OS X :: Frequent Wireless Disconnects - How To Repair
Mar 31, 2007
When I turn my computer on or wake it up, I am 'connected' or so it says, but I am never able to reach the internet until I (wait a long, seemingly random amount of time or) disable my wireless adapter, re-enable it, and select my wireless network.
I did not experience this problem prior to:
-Trying out a new AirPort Extreme, returning it and going back to my old G router. The AirPort worked great for this computer, but it had problems with the PCs and the xbox 360 (yes.. i know there is a workaround now...)

I recently purchased the $1699 Macbook Pro a couple of weeks back and now it seems that my airport randomly turns off. I can't even get it to turn back on; I have to restart my macbook to get it working again.

I have the Samsung SCX 4500w and its IMPOSSIBLE on wireless network.
Once I have paired it, which I?ve done four times now, after some time, for some reason - it disconnects itself from the net.
So I cant access the IP adress, even though the configuration-report says that its still connected and has the same IP. So it wont print, unless I turn it off, and pair it with my router again.
Samsungs customer service refuse to help me. They dont have a clue on how to resolve the problem when it comes to Macs. They dont even know OSX, they dont know the interface. They are just guessing what I have to do, and its shocking and awkward.
Samsung really sucks with customer service for Mac!
Does anyone have this printer? This is driving me completely insane, and I dont know what to do. Im considering returning it, and never buying a Samsung printer again.
This is too bad, because the function is great, quality and design is great too. The few times it works, its great.

I have a new (June 09 model) 15" MacBook Pro, 2.66 GHz and I'm experiencing frequent (every 3-5 minute) drop outs on my wireless internet connection, but only when I'm running Mac OS X-- my Windows Vista Ultimate partition is operating flawlessly. After Googling, I have come to the conclusion that this is extremely common in MBPro's since there is such a saturation of search results?
Background on the wireless networks used:
- home: 128-bit WEP-open
- work: WPA2-Enterprise
Again, I haven't experienced a single disconnect when running the following:
- Vista - wireless
- Vista - wired
- Mac OS X - wired

1x Macbook 2.4Ghz, 4Gig RAM. December 08 model.
1x 24" monitor connected via DVI connector
1x USB mouse
1x mac wireless keyboard (was used on iMac 21.5" new 2010 model)
Latest version of Snow Leopard, patched to the latest on everything. Software update says that everything is up to date.
I've unregistered the keyboard with the iMac and associated it with the Macbook. I'm typing this message with the wireless keyboard no problems.
This is where the problem comes in, when I start up for example MacTheRipper, or Handbrake. Essentially any tool that kicks the CPU into overdrive the keyboard starts acting strangely.
Typing will go to a crawl, it takes longer for the letters to appear, as if in slow motion. It will popup the keyboard disconnect and reconnect image every once in a while and if I leave the keyboard for a while it will disconnect from bluetooth completely, when I then try to reconnect by tapping a key it doesn't connect for sometime. Even if I hold the key down for several seconds.
Once the program has completed processing and the CPU drops back down to nothing, the keyboard works just fine again.

Recently got the new Mac pro and the internet connects briefly via (wire less) and then disconnects after 30 secs. I notice the DNS server switches numbers. After this happens I no longer have internet connection.
Connecting via ethernet is no good either. It doesn't connect at all. I did do a migration from another system. I am wondering whether the setting were saved from my previous system and are getting corrupted with the new system.

Mac Pro, OS X Mavericks (10.9.4)

My MBP recently had a bunch of problems with the logic board and speakers. I brought it into the Apple Store (on Monday) and they gave me the option of them sending it into a repair center, or them repairing it locally in store. I requested that they sent out just because I was curious to see how long it would take. To my surprise, my MBP arrived, fixed and as good as new on my doorstep today. That's amazingly fast for sending it out to a offsite repair center. The repair center is in Philadelphia. I live in Maine. You do the math. When I've had things repaired locally in the Apple Store it's taken weeks to repair instead of days because they need to order the parts.
Anyways, the point of this thread was to suggest to people that they choose the offsite repair option. It's amazingly fast, and it saved me a trip to the Apple Store (they shipped my MBP directly to my house).

I took my late 2007 macbook in because the case was cracked. I read that this was a known issue and they would repair for free.(I had no warranty) also my battery was expanding and bloated, so much that it will no longer fit in my comp.
When I took it in, the tech said that my bottom case was cracked and he said that wasn't part of the known issue. He said it was caused by accidental damage (it was cracked clean through, so much so that it could be physically separated from the comp.(I informed him that the comp had never been dropped or damaged in anyway, he apparently didn't believe me but said he would see what he could do.
Anyway, he said he could fix the top case ( but they would not fix the bottom case)and give me a new battery although he had never seen a battery with the problem that mine had. He said it was probably expanded cells. I agreed to that as something is better than nothing but then, I asked him if the battery expanding could have caused the bottom case to crack since it was cracked near the battery compartment but on the side of the comp. After he tinkered around for a bit with the battery and the cracked part, he said he wasn't sure but he would send it in for repairs and I would not be charged.
First he said he would quote me a repair price and I told him that I had no intentions of paying for anything. After several instances of him running to the back to talk to people, he agreed to send it in. On the repair form it is listed as tier 4 accidental damage and I know that the tier 4 comes with a hefty charge for repair. Anyway, I am out of town and my comp is scheduled to be returned to me today. I dropped it off at the apple store on the 30th, it was received by the repair center on the 1st, repaired today( the second) and shipped back to me today and scheduled to be delivered today as well.
I was trying to find out if they actually repaired the bottom case or not as I will not be home to receive my comp until next week sometime. The repair form also said call if additional repairs are needed to quote a price. I have not received any calls at this number and do not know if they left any messages on my home phone. The repair turnaround seems rather quick and I was just wondering if they actually repaired it or sent in back in the same condition.
Apple support has no details of the actual repair just the time it was received, repaired and sent back to me. Also will they just leave it outside because no one is home to receive it?

I have a linksys BEFSX41 v2.1 router (not wireless, hard wired) router. Ever since I hooked my macbook to it is appears that it drops and the reconnects regularly in regards to iChat. I am using my AIM screen name, and I receive this message "Error: Serv:RequestTimeout" frequently. This makes it tough because I can never tell if the person got my last IM or not, and since my screen name signs off and then back on again all the time it drives my friends insane.
I can get AV chat going, and I can use screen share with other macs. I enabled UPnP on my router in hopes that would work but it does not appear to have fixed it. I tried opening up a port that I heard AIM uses (5190) but that didnt fix things either. I'm thinking opening ports probably wont work since if I can IM people, or AV chat without having opened any ports then the program must be already opening ports as needed on its own.

I recently upgraded to OS 10.5 on two desktops. The PowerMac Intel works fine. The G5 Quad seems to be having weekly kernel panics and frequent software crashes (an example yesterday: Word and Safari were open. After a few minutes of no keyboard input whilst reading a webpage, Word crashed, followed by Safari). Running Maya seems to cause the kernel panics. It did so, once in a while, on OX 10.4, but with 10.5 it's become a frequent occurrence. Calling Apple (still on Applecare) doesn't help. They run some diagnostics and can't pinpoint anything. Clearly if they don't recognize the problem, they can't fix it. (I also run Maya on the PowerMac Intel with no problems, so Maya isn't the problem.)
Realplayer, streaming, has been playing during some of these occurrences — is this a known culprit? Any suggestions? Was the G5 Quad just a bad model? Can I turn off whatever causes the kernel panic alerts that freeze my computer? Should I be demanding more out of Applecare — is there anything I should expect them to replace? Should I downgrade to OS 10.4? If so, how do I do this? Many questions I know...

I'm new here to this forum and I'd like to get some advice. I've had my 2008 macbook 2.4ghz-160gb since august of last year. I upgraded it to 4gb of ram in the early stages and had no issues till lately.
For the last week, almost daily, Id get the beachball for a long period of time. This happens most frequently when I surf the internet. Occasionally this may occur when i play music in itunes but that is probably due to my library being store on an external hd. With that being said though, as I mentioned, it most likely occurs when I surf the internet. Many times, its not just a browser crash but a system wide crash where my mouse can move but when i click anything in the background, it would have no effect (but my mouse can move still). Only way to 'resolve' this was to do a hard shutdown and restart by holding the power button for few seconds. Of course, this issue keeps happening and it pissed me off so I looked around the net to find some possible solutions and many sites claimed flash being an issue. I uninstalled flash and retested and the problem still occurred. Reading maclife, it mentioned about some fsck -fy thing during boot up so i ran that test and found no errors. Restarted again, did some surfing and still the problem.

I recently (2 months ago) purchased a new mac book pro and migrated everything from my older mac book pro running Snow Leopard to Lion.Since moving to Lion I have been experiencing frequent crashes of Mac Mail, I spend a large portion of my work day in mail and experience this as many as a dozen times a day. Mac Mail will crash while
1) composing an email,
2) when clicking a link in an email
3) clicking the attachment icon to add an attachment
4) clicking on an attachment that has been sent to me
5) somestimes just trying to exit/close Mac Mail and the it hangs and I have tp force quit. After Mac Mail crashes and is restarted, clicking on the same link or attachment will workI have removed my mail IMAP folder and settings and re-established the connection from scratch but the problem persists.I have ran the disk permissions repair utility and the problem persists. I have ran the verfiy disk utility and it reports no problems.I have ran the Apple hardware tests including the extended tests and no hardware issues are found. Has one experienced somewthing similiar?Does anyone have any suggestions where to start looking for the root cause? All crash reports seem to look [code]

I have a Mac Pro Early 2008. Here's my set-up: BootDrive (Mercury Excelsior PCI SSD 240 GB): contains OS X and applicationsDataDrive (2.25 TB RAID 0 with three 750 GB drives): contains files, pictures, music, videoTime Machine Backup (2 TB drive) Recently I've been experiencing frequent crashes. These mostly happen when the computer is sleeping. For example, I'll put it to sleep before going to bed, and I'll wake up in the morning to find it unresponsive when I attempt to wake it up. (Also: the computer tends to be waking itself up from sleep, i.e. I'll wake up and it will be powered up, even though I put it to sleep the night before.) When I notice that it has crashed, I hold down the power button on the tower until it shuts off, then press it again to start up. When I do, it boots into Safe Mode. Does this suggest a problem is due to a peripheral or drive?
The first time this happened, one of my internal drives got corrupted and I had to use Disk Utility to repair it. The second time it happened the permissions on my data drive got screwed up, and a few files on that drive got corrupted (including my Lightroom library). It just happened a third time, and once again the permissions on the Data drive are screwed up. If I recall, this all started happening after I installed the Mercury Excelsior PCI SSD. But it appears to be functioning well. I've run Verify Disk and it says it has no problems.

I use Mail on 10.9.3 with multiple IMAP accounts (but almost nothing the servers, all local in many folders). In the last days Mail started to crash several times a day, mostly when I interact with messages (replies, moving to folders, attachment stuff etc.) I am too fast for Mail - but that never was the case before and I have a fast machine and Internet connection.

I own a few external harddrives, however one in particular (western digital 2tb) will randomly disconnect and a window will show about "device removal with the red little stop sign shape" then it will randomly connect again (and sometimes i have to physically unplug it and plug it back in), does anyone know what is going on here? None of the cables are being touched, it's really strange, the only thing i can think of, is maybe i have a loose usb cable and need to replace it? or maybe a faulty usb port?

We have Comcast internet hooked up to a Linksys router. When only Windows machines are using the connection, everything works fine. When I use my Macbook Pro on the connection, it works for a while, then eventually the connection dies for everyone, and usually restarting the modem makes it work again. I am now trying to use the connection on Windows XP on my Macbook Pro using Boot Camp, and it seems to be working, so it seems like the modem doesn't like something about Mac OS X.

I'd like to be able to VNC to my Mac at home. Here are the steps I followed (on my Mac - latest version of Leopard)
1) In the "sharing" control panel options I turned on Screen Sharing
2) In the screen sharing options I set "allow VNC access with password" (or something like that) and set my password
3) On my airport extreme I entered "manual setup" and in the port forwarding menu (I forget what it's called) I selected "remote desktop access" from the dropdown menu. That seemed to add the correct ports (5900 was one of them), and I entered my local IP address for my mac in the dialog as well.
NOW, here are my symptoms:.........................

I didn't know where to put this question, so I thought this would be the most appropriate. My computer (A macbook pro, with mac OS X, version 10.4.11) will randomly disconnect from the internet, mostly when I'm playing online games. Sometimes I can play for hours, other times only minutes before the next DC. I can restart and it will work for a few more minutes. The funny thing is it only does this when using the wired connection at my apartment, when i'm using the wireless at college it works fine. Part of my inquiry is checking if it's my computer or the ISP. None of my roommates have similar problems (though they all use PC's). One interesting thing I found when a tech from the ISP was trying to fix things is when I try to renew my IP it gives the same address after it "renews". I know I threw alot of jumbled info out there, but I'd like input from someone who knows macs.

I'm using my G5 for both personal use and work so it's on all the time. It has worked flawless with this same hardware config for almost 2 years, but for the past week or so I've had about 4 to 5 kernel panics or complete system freeze a day. This happens when doing web browsing, Final Cut Pro editing, playing a game etc, so basically I can't pinpoint it to a specific application, or to a piece of hardware I've added. I have ran REMBER to test my ram and all seems fine.

As the topic suggests I keep getting kernel panics when playing games on the 9600 m GT (it never happens on the 9400 m). I never have kernel panics when playing left 4 dead 2, but I get them playing left 4 dead 1 and games like WoW and Age of Empires 3. Here is my crash report, and I don't game in bootcamp. Running 10.6.5 on a late 2008 unibody macbook pro. Can anyone tell me from the crash report what's going on?

I'm kinda concerned about my MBP, though nothing's been happening to it as of yet.Basically, I've been putting it through a lot of gaming and encoding recently (this thing performs like a champ).I'm just concerned that any of this could potentially shorten the MBP's life.
I know that excessive heat can shorten logic board life.When encoding, the CPU's around 200-205 degrees Fahrenheit, same for gaming.The fans run fine, and it feels to be about the same temperature every time (I use smcFan Control in OSX and Lubbos in Windows 7).

I open and close my 2010 MBP a lot. Maybe 15 times per day. Am I running the risk of breaking a cable between the base and screen or something? Should I just set it down and let it run?

I have a Macbook Pro that's about two years and 4 months old, running the latest version of Leopard. I was problem free for about two years until last October when my MBP suddenly wouldn't boot up (hung at the grey apple screen). I took it to my University's computer repair center, and they said either there was a corrupt OS file, or my HDD was going bad. I went home and booted from my OSX disc and did a full erase and install. My computer worked fine for a few months following the erase and install

My macbook pro's HD is in bad shape. S.M.A.R.T status is not ok. Sometimes the OS freezes, but so far this is the main problem I detected so far. Until now. I reinstalled the OS X - clean install - to see if things got better, but no luck. Although I think the system is more stable now, the machine is unable to restart or shut down as before. I have to hold the shut down button for a couple of seconds. With this in mind, is it dangerous for the machine to do frequent force shut-downs, or it just deteriorates the HD even more?

i'm experiencing frequent kernel panics on Lion with 10.7.3. This has only started occuring in the last week with no obvious changes before it started. I've repaired disk permissions, used OnyX to clean everything up, and it still occurs (approx 4-5 times per day). My computer is a 15" MacBook Pro with 8gb ram, 2.66 GHz Intel Core 2 Duo, NVidia GeForce 9400m 256mb video card. It seems to occur more frequently when I have an external drive attached (either Firewire or USB). As my profession is video editing, it's not really viable for me to simply not have one connected!! This is starting to get quite frustrating as it interrupts my work significantly.

There appears to be a rather serious (IMHO) design oversight in OS X's file system routines, as concerns the handling of external drives with power-save features. I've never bothered mentioning this online before, as I've always expected it to be resolved, "in the next update". But I've been waiting now since 10.4 Tiger and nothing yet. So I figured I'd raise the issue in here, at least to see what others might have to say about it.
I keep an external (Seagate) USB drive connected to my personal iMac, for use mostly by Time Machine. I'm sure I'm by no means alone in this practice. :-D The drive is, of course, modern and nice enough to power down when not in use (well, "spin down" at least.) The trouble is, even though OS X's disk caching system really ought to know (IMHO) that the drive has not been unplugged or accessed by anything else since OS X itself last did so -- alas, for the likes of Save As ... dialog boxes, we still get a several-second Finder UI "lock up" -- usually accompanied by "the spinning beach-ball of death" -- while the OS merely waits for the external USB drive to spin up and say, "Yup. Still here. Nothing has changed and all is well. Carry on!", before finally presenting the list of places I might want to save my file at.
This happens in all applications, apparently any and every time the OS wants to refresh the list of available storage devices. So it's obviously an OS X cache/driver issue, as opposed to anything in user-land. Wouldn't you agreed?
I guess my first question would have to be, "Is there something I've not been able to find, which I can in fact already do to fix this problem?"
I know it's not just me, actually, because we have five (5) Macs in and about the home office, which all exhibit this highly frustrating behavior. Two use Seagate USB drives (one is 5.25", the other 3.5") while two others use Western Digital drives and the final has two Samsung drives, in custom enclosures. In fact, that last machine -- with an second drive solely for additional mass storage -- has us waiting while both drives spin up, in turn, which is frankly just terrible.
Indeed, the retired TV producer gentleman who owns this particular machine, swears that his iMac is, "the worse Mac I've ever owned", solely because of this problem of, "... constant $@#% delays ...", as he puts it.
Meanwhile, I've been trying to convince the old fellow that doing a full system re-install is highly unlikely to fix his problem. He harkens back to the days of OS 7?P.S: While I remember it -- there's another problem you might have come across, whereby if an external display is connected but turned off, the UI (mouse pointer etc) continuously pauses about even second or so, forcing me to either unplug the external (DVI) display or leave it turned on, even when I'm not using it for hours on end. This one is not nearly such a biggie as the USB drive one, in my view. But a curiosity, none the less.
