PowerPC :: Ethernet Not Working Properly - Randomly Connects / Disconnects
Oct 11, 2006
I've been having problems staying connected on my Powerbook G4. The wireless works perfectly but the ethernet does not. I've been using the dorm ethernet jack to connect. The problem is that my computer can't maintain a consistent connection through ethernet so it randomly connects and disconnects. I called my campus' IT department and they told me that it must be my computer because they're system said that it didn't detect my computers IP address. I called Applecare and the person told me that it must be something wrong with either the network card or the ethernet port. Anyway, he gives me a case number so I can go get a repair. Unfortunately an Apple Store is far away from where my school is so I went to my school's bookstore instead.
The bookstore is an authorized service place. I drop the computer off to them and they sent it to Apple. I got a call today from the bookstore guy saying that the Apple technicians discovered that "liquid" had gotten into the motherboard and refused to service my computer. I was really angry when I heard this because I keep absolute care of my laptop. I know for a fact that no water has ever been around my laptop. I'm guessing it must have been negligence on the bookstore's part. I declined the $1300+ repair estimate so now its on its way back to me. I have a brother that works at the Apple Store and he just suggested going directly to an Apple Store this time. Will they just refuse warranty repair again?

So, after getting it hooked up and connected to my router, which is set to only allow only 4 devices to have access to it (my comp, iphone, wii, and gf's laptop), i find that my gf's laptop (which is the only device using a corded connection) is the only machine able to get online without problems now.
I can pick up my WiFi network occasionally after a restart, but then it usually goes out after a random amount of time... anywhere between 10 minutes to an hour or 2.

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)

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?

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.

My iBook G4 is having network issues. Since waking from sleep, it will connect to my Airport Extreme base station, but I can't access the web, or access the router from Airport Utility.
Things I've tried so far:
*Rebooting
*Resetting the router to factory defaults
*Swapping out the router for a Linksys
*Clearing out network passwords from Keychain
I doubt it's a hardware issue, as everything works in Tiger (booting from an external drive).

I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.
I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?

My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.

I have a external SATA drive that was used on my old Windows laptop. The interface for the drive is USB 3.0. Whenever i try to view my files on the drive, the drive randomly disconnects, and notifications pop up saying that the drive was not ejected properly.
Also the drive has been reformatted to a Mac format, but it still continues to do this.

MacBook Pro with Retina display, OS X Mavericks (10.9.4)

I have had several issues with the USB on my brand-new Core i5 macbook pro. It randomly disconnects USB devices. I've had the issue with multiple USB devices - same story with each one. Further, iTunes will only recognize my iPhone if it is in the port nearest the magsafe connector. The other port fails to recognize my iPhone entirely. Anyone else having a USB issue on their base 15" that was released today?
Furthermore, any suggestions of what to do about it? I'm having a hell of a time restoring my iPhone with this issue... And the Apple Store is over an hour away-I planned a special trip to buy this laptop.

I'm renting a house for the week with several friends, and there's only one ethernet port. I figured I could plug one friend's Powerbook G4 into the ethernet, go into Sharing, turn on Internet Sharing, and then nearby computers could borrow the connection - this isn't working. The network doesn't even display on my other friend's powerbook. The little upwards arrow does not display ontop of the airport icon in the menubar, which I think it's supposed to, what's going wrong? I have "Personal Web Sharing" turned on under "Services," still no go...

I'm running OSX 10.5.8 on a Macbook Pro, and today I've been unable to connect to the internet via ethernet or wi-fi, unless I'm in safe mode. Then everything seems to work as it should, which makes me believe that this is a software issue rather than a hardware problem. I've tried making a new account with administrator priveleges, but that doesn't solve my issue. Does anyone have any advice on how I can connect to the internet under my normal user account, rather than in safe mode? I should note that I won't be able to get my hands on my repair CD or perform a clean install of OSX because that stuff is at home, and I'm in college. Also, I'm at a university and don't have a router. I just use the campus-wide wi-fi. Finally, my roommate has no problem accessing the internet in our room via ethernet or wi-fi, but I do. Thanks for the help everyone.

I originally posted on needing a reliable way to extend an open network so my Macbook's waning Wifi would still get some kind of service. Recently, however, my Macbook will not maintain a reliable connection for more than 5 minutes when sitting 2 or 3 feet from the base station, so buying a wireless repeater is obviously not my only concern here.
I would normally plug in the Ethernet directly from the modem, but my Ethernet jack will not respond. No connection whatsoever. I've read in other places that this is a logic board problem, which always means expensive or impossible. Is there another option?
I would send the thing in, but my warranty may have been used up replacing the hard drive when it fried.
I'm getting to the end of my rope. Is there a semi-reliable fix here? I have owned Macs all my life and have NEVER had this many problems.....
P.S. the reason I am looking for a way to maintain a reliable connection is not only for convenience. I'm working as a data entry station for a company and I need to stay connected to their network for more than a few minutes.

iBook G4 shows that the airport has full connectivity (full bars) yet it doesn't connect and states that there is no IP address. The iBook connects using its internal airport to a Netgear Router. There is a PC that runs windows that is connected to the cable modem. For a month or so both computers were able to access the internet simultaneously. All of a sudden the computers are unable to access the internet at the same time. When I attempt to connect at the same time my Mac gives me an error stating that another IP is in use and so I can't connect.
How can I give my iBook an IP address so that both computers can be online at the same time?

I have no idea what has changed other than I have been messing with GeekTool today. Some of my widgets are not working properly.
iStatPro
VersionTracker
and any WebClip widget
They are all stuck at a fixed size (not the same form one to the next) and redownloading has not fixed the problem.

out of the blue about 3 months ago my MacBook(version10.4.11) started refusing to recognize my home wireless. the problem has now reached the point where it AT TIMES will display that the wireless newtwork is on in the toolbar yet the computer will not jump onto the internet. Now it has reached the point where it won't even show that it sees the wireless in the toolbar. I have reloaded all passwords , checked the Verizon wirelss set up, reloaded firefox , checked all firewalls. The wierd thing is that my kids macbook is fine. Mine is the one with the problem.I checked all my settingts to correspond/copy hers and they do. Have zapped pram too. It works fine EVERYWHERE else but home.

I have an iMac Core 2 Duo running Snow Leopard V10.6.3 with 4 GB RAM... I've seen the threads regarding the inability to "Empty Trash" and the error code. When I open the Trash window, it is empty. When I place a single item into Trash, there is one item seen in the window. When I Empty Trash, there are then six items being deleted. If I place three items into Trash, then eight items are deleted... etc., etc. What are those weird ghostly five items??

Starting about 4 months ago my 3 year-old 2.0GHz Core Duo MacBook's wireless started to not work very well. What was happening is that after starting the computer or waking it from sleep, it was able to connect to my network, but after about 5 seconds it would lose the signal despite being physically very close to the router without anything to block the signal. The problem progressively got worse, and at its worst it was only able to connect about 1 in 10 times. Either it wouldn't find the network at all, or it would find it but couldn't connect because "The connection timed out" or something like that.
I never bothered fixing the problem because my Mac was having a bunch of other issues at the time, so I was just going to fix them all by doing a fresh install of Snow Leopard once it came out.
So 3 days ago I did a fresh install of Snow Leopard (I formatted the harddrive then did a fresh install, not an archive and install). Unfortunately, it only kinda helped the wireless problem: I can now connect half the time rather than 1 in 10 times like it used to be.
I'm quite sure my network isn't the problem because everyone that has used my network in the recent past (which has been about 10 different PCs, Macs, and iPhones) hasn't had any problems. FYI, I have a Linksys WRT54G wireless router.

Suddenly my Wacom Bamboo Fun isn't working properly. The pen works fine but the mouse is eratic and wants to open everything it touches. The clickers don't seem to work and it seems to be clicking on everything on its own.I downloaded the most recent software and it hasn't changed anything. I have Leopard on a Mac Powerbook Pro.

I've got a macbook pro unibody and basically of the two usb ports. The lower one is working fine
but the top one is acting a bit funny. If I put my mouse or graphics tablet in there it doesn't work but if I put my phone or usb drive in there they work perfectly.

After doing the superdrive update 2.1 on my macbookpro the drive stopped working. I have tried all the numerous fixes posted on the web. Nothing works. Among other things, I flashed the drive and it now shows as set to all regions, but still doesn't work. Region X cannot change the region either.
Is there any useful news about this widespread problem?

After re-installing Lion I've had this very annoying issue with tap-to-click on the trackpad of my MBP. While it seems to work most of the time, I often have to move the cursor away from the button or click on a window as if to make it active in orer for the click to work. A similar problem is occuring in MS Word when I'm going through the spell check process - I have to sometimes click "ignore" multiple times or click somewhere else in that window for the click to register.

I have a macbook pro running 10.6.8 & the cap lock turns on when I press the 2nd bracket key. The cap lock stays on until I press the 2nd bracket key again. It will not turn on when I press the cap lock key or shift cap lock key. I tried resetting all shortcuts in system preferences & rebooting the computer, but it is still the same. I can't use the 2nd bracket key now
