Every time I log into my imac system, i have to reestablish the network connection running the diagnostics. This only became an issue after updating the OS; I run a time capsule as my modem. This is very irritating, any recommendations?

My iMac is set up wireless. Every time it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network and request it to reconnect to my home wireless network. It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

every time i open my macbook pro from sleep mode there is no internet connection, even though my wifi bars are full and black and my home router is found and ticked. after a 1-2 minute delay my mac then connects to the internet. this happens every time i open my laptop from sleep mode. i have to wait 1-2 mins. this has only started to happen in the last few days and is driving me mad as it shows it is connected to the internet.

I have 2 x 2Tb external hard drives (Hitachi Touro Desk Pro), both of which have been formatted. I am using one of them for my entire iTunes Library, whilst the other one is being used as a Time Machine back-up for the first external plus the MacBook HD.Â
All is fine with both drives until I go to use Time Machine. The external with the iTunes Library will just lose connection and I get an error message saying that "the disk has not been ejected properly and may result in damge...etc..." - just like the USB cable has been yanked out (which it hasn't). I then have to unplug it from the Mac and unplug it from the power supply, then re-conect it all for it to be able to mount again.Â
Not sure why this is happening and am getting worried that this behaviour is going to damage the drive which has all my iTunes music, TV shows & movies on it, before I get a chance to back it up.Â
Could this be an external drive issue, a cable issue or a Time Machine issue??Â

Recently my MBP (mid-09) has had issues with airport as it continually loses connection and I have to turn it off and on again in order for it to work again sometimes within seconds of doing so. I would opt for a fresh install but my dvd drive seems to be scratching the dvds and it rendered my Windows XP DVD useless when I tried to install that. So it wouldnt be ideal unless there is a method of doing so without using the dvd drive.

I use my iMac for business. So even if the mouse loses connection once a day, that it 1 time too many. Some days it loses connection 2 to 3 times a day. When it does this, I go into system prefs/mouse and it says no mouse found. Sometimes it will find my mouse, then it after searching for a minute or 2, goes back to no mouse found and searching.
Sometimes it finds the mouse and sometimes it does not. Right now, I am using a hard wired mouse. Its been about 5 minutes and its still not finding my apple mouse. In fact, this all started after I replaced the original batteries. The mouse was working flawlessly up until that point. Its a brand new 27" IMac I got Christmas 2011, so its running Lion.

My 2011 Macbook pro i7 has a chronic problem: as soon as it goes to sleep, the wireless connection is lost, and has to be manually coerced back to the computer by turning the wireless off, waiting several seconds, turning it back on again, and waiting for it to find the router again. It finds the router in a few more seconds, then everything is OK until it goes to sleep again. Â
A real pain in the butt, and shouldn't be a problem on a supposedly high end computer. Â

I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here [URL] ...., which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem).Â
I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection. Â
My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes:Â
1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets
2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).
3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.
4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets.Â
The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.Â

Just got a new MacBook Pro a few months ago. Migrated everything successfully from my old MBPro. Now, however, when I wake my computer each morning, it can't connect to the internet. It shows that my wifi is connected, but when I try to get mail or use Safari/Firefox/Chrome, it just spins until it tells me I have no internet connection. I then have to restart the computer and it works fine after that.Â
The fact that it works fine after restarting tells me it's something other than my wifi or my cable modem.Â
I'm running 10.9.3. Using 'Automatic' location.Â
Everything was ok until last night when I noticed this. I'm sure I didn't change anything manually in the network settings, but now I can't keep a connection for more than 10 mins. To get it back again I have to shut the airport connection (checking the diagnostics, I get a red light on the ISP circle,yellow on Internet and server) and that lasts me another 10 mins
so far I've tried sending pings, deleting this network entry and adding it back,changing the router position, but no luck. I'm able to check the router settings (tp link), but not sure what I should be looking for
the laptop works fine at my sister's place. It's just this network at home I'm having troubles with. the same thing happened all of a sudden with my imac,so I left the Ethernet cable connected to that, as it's right next to the router and it works fine.
I try to use my new Mac Mini has a HTPC. However, when in the middle of watching video, say 20 minutes in a show or something, the warning keeps coming up on screen "lost connection," with the keyboard. Anyway around this? Doesn't seem like you should have to use a wired keyboard, for a computer that so many use in the living room?

Looking at my console log I see that my computer is being woken up repeatedly by Time Machine.Since I don't backup every hour this seems to be a wasteful interruption to Sleep Mode, and effectively disables it; not something I want. The console message I see is "Not starting Time Machine backup after wake"..Is there a parm that I can set somewhere to prevent this? I have "Don't wake for network access" set but that seems to affect incoming rather than internally

Problem with Time Capsule acting as a router for home Internet connection. It would lose it's WAN IP address after 5-10 minutes, sometimes longer. Rebooting the Time Capsule would fix it temporarily. Also, renewing the DHCP lease for the Time Capsule using the Airport Utility would bring it back instantly. It's a 500 GB Time Capsule and has 7.4.2 firmware. An update check says that that's the latest. I tried a factory settings reset. At first I thought it helped because it lasted more than 20 minutes afterward. But then did the same thing again.
Some background: Time Capsule faithfully did it's duty at another home for extended period of time without any known issues. At old home it was connected to a different cable modem - an RCA I believe. At the new home it's connected to an Arris modem that provides data and voice. For the first three or four hours it worked without issue, then it started losing it's connection (right about the time I was leaving )
The cable company tech had me believing that I had a glitchy Time Capsule. Now I think I have either a:
- incompatibility between the Time Capsule and the new Arris Telephony cable modem
- network conflict on the cable company's side of things. The Time Capsule was running connected to a different modem at a different address (and account, I believe).
- final choice is a glitchy Time Capsule.
(I first wrote this post on 9/30/10, at that time firmware 7.4.2 was current, now 7.5.2 is latest. I'm attempting to recreate the problem now. This happened at a client's home with their setup - I'm now hooking it up as my main router and using the same Arris Telephony modem. It's been running with my Arris Telephony modem on my Internet connection for over twelve hours without issue).
I have Alltel Mobile Broadband. Up until the other day, it's been working fine. I'd set up a network on my macbook after connecting to the Alltel network, then I'd enable internet sharing. Then my iPod Touch, iPad, etc would all be able to go online.
The past couple days, however, the connection just won't share.Anyone have any idea what could be doing this and how to fix it?
I have the current generation $599 Mac Mini, with Nvidia graphics (just to clarify the model).
My wireless network is setup from an Airport Express.
My iMac, Powerbook, iPhones, Apple TV, Wii, etc. can all stay connected without problem.
However, my Mac Mini loses the connection constantly. It shows full signal, but then it drops out 100 percent for a few minutes, nonstop all day. It makes it completely useless effectively.
What kind of settings and things could I try to change?
Or, is this likely a hardware issue?
When i wake my 2.4 Ghz aluminum MacBook with 4GB ram from sleep it takes the AirPort about 10 minutes to connect to the internet. The status is that the AirPort is connected but there is no internet coming through. What could be making my MacBook take so long to connect to the internet?
View 2 Replies View RelatedI've searched and don't see anybody else with this problem. I tried to set up an ad hoc network on my MBP so I could use TouchAble with my new iPad. But now I can't get my MBP (or iPad) to see my home wifi network.
(TouchAble is a music performance app on the iPad that controls Ableton Live on the MBP. It works on an ad hoc network so the combo will work on gigs without depending on local wifi.)
I set up a new network ok, with a password. The iPad saw it, but before I tested it further I wanted to make sure I could reinstate my regular network. So I tried switching back to the regular wifi. No dice! The MBP sees the network, but I can't log in. It acts like the password is wrong. Same on the iPad.
Yes, the network works. I didn't make changes to the settings in my router, and my iPhone still sees it with the same password.
I tried a tip I found online and deleted the network preferences file (com.apple.smb.server.plist) and rebooting. No dice. (The system didn't write a new one, as I had expected; I had to reinstate it from the Trash). I rebooted a few times, both MBP and iPad. Nope.
What's going on here? 1) How can I get my MBP to see my network, so I can switch back and forth from the ad hoc to the local network. 2) Ditto for the iPad.
MBP is new. All systems and versions are up to date. No other funny stuff with the network--it's been stable for two years. Everything is stand-alone; this is in my home office. I'm the admin. (But I'm not a techie, so if you start talking about IP addresses and subnet masks, please be clear what I should try.)
I have a late 2008 Unibody MacBook 13" with Windows 7 Ultimate x64 installed under BootCamp upgraded to 3.1.
Here's my problem: when I'm connected to a wired network that uses DHCP and I wake from sleep the adapter does not acquire the IP. I need to disable the adapter, reenable it and everything works fine.
After Lion upgrade I cannot get my remote access program (Timbuktu) to show my desktop to remote users. The sleeping screen (not the hard drive) is set for "Wake for network access" and all other settings are checked and appropriate including an update to the newest Timbuktu 8.8.3. The screen wakes from keyboard or trackball activity but not for incoming access. Note: The remote user sees the frame for the desktop in Timbuktu but is shows a sleeping (dark) screen. The file and clipboard exchanges still work but the screen ignores the instruction to wake. Access worked perfectly with Timbuktu until three weeks ago. Then it just sleeps like a teenager on Saturday morning unless tapped on the shoulder by a parent. Call-ins don't get answered.
