Computer loses Wifi connection

Every 15 minutes my computer tells me I am not connected to the internet. I go to diagnostics and when I select my network the red lights go out , turn green and say my connection is working. This happens over and over. My son has a pc that does not lose the connection when my Mac does. Any ideas?

My imac loses wifi connection when it goes to sleep, how to correct?

My iMac loses wif connection when it goes to sleep. How do I correct?

Are you running OS X Lion? If so there are unfortunately numerous threads on here discussing exactly the same problem. So far there doesn't seem to be a definitive solution, with everyone hoping that Apple will come up with a permanent fix.
Here's a quick search of these forums alone - depressing reading:

This 'fix' has worked for a few people but, unfortunately, not everyone:

Why does my airport loses wifi connectivity often?

I am trying to find out my my airport loses wifi connectivity. All of a sudden, there is no wifi in the house. What do i need to check?

Hey barbaraeberle,
Thanks for the question. I understand that your AirPort seems to have lost its connection to the internet. To troubleshoot this issues, let’s try the following:
See if you can isolate the issue first by using Wireless Diagnostics:

Additionally, check for sources of interference and reset your base station:

My ipad loses wifi connection every night, why?

My ipad loses wifi connection every night, why?

This is a user forum so no one here would know Apple's plans. By the way the problem may very well not be Apple's.
Even if your router is "new" visit the manufacturer's support web page to see if there is a firmware update for it. Also check to see if there is a support hotline or forum.
If you need more help please give the make, model, and version of your WiFi router.

My iPad 2 loses wifi connection on home network?

My iPad 2 loses wifi connection at home, iPhone remains constant and macbook remains constant. iPad rechecks every couple of minutes, then about every 15min or so loses connection, then I have to reselect network. Wifi is working on husbands iPad and iPhone without problem... suggestions?
Is a pain while surfing - suddenly get the "no internet connection", have to exit and go to settings and reselect the network. Frequently takes more than one attempt to reconnect.
Thanks

Try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.

Itouch loses wifi connection constantly

itouch constantly loses wifi connection, similar itouch has no such problem, updated software to latest version available but issue persists

Additional information, I have D-Link router that came free when I signed up with my cable company so I'm sure it's a basic model. I did update the firmware to the latest and greatest as well.

Time Capsule continually loses wifi connection

What causes time capsule to continually lose wifi connection with iMac (Early 2011 - 12,2) and how can I prevent this?

Troubleshooting Wi-Fi issues

Lose wifi connection

The last 6 mons or so, since buying a new macbook pro, iPad and macmini my wifi randomly disconnects to my airport extreme and therefore to all items in the house (including my iphone) and I have to go unplug it and plug it back in. It can work for days at a time or cut out over 20 times a day. It is incredibly frustrating. Is this fixable or just a giant bug for me to enjoy? I love mac products but this is incredibly frustrating.
Do I have to recreate my entire wireless account on the airport from scratch again to fix it? If so, how? It was working fine with our old macs until we upgraded everything.

Not sure that is the issue, as the airport extreme is directly connected to the shaw internet connection box by cable, yet still somehow loses internet connection. The two units are right beside each other. When i unplug it and plug it back in after a minute the wireless is ok again for a while. The issue is all my computing items will randomly all of a sudden lose wifi signal...nut just reduced bars but the signal is gone all together. It is wierd.

Loses wifi connection

Hi. I experience an intermittent problem with my Macbook Pro. Occasioanlly, after waking up after sleep mode, it loses the wifi link. I have it linked to a WEP protected hidden network. The only way (that I have figured out) is to restart and it finds the network automatically just fine.
Anyone have any ideas?

Hello redticket
For that issue, follow the steps in the Symptom: After restarting or waking from sleep, my computer might not connect to the Internet and that should resolve the issue of when it disconnects and then does not reconnect.

When my daughter connects to our home wifi she has to be within 5 feet of the modem, once she moves upstairs she loses wifi connection and then when choosing the network, it can't find our wifi network?

When my daughter tries to connect to our home wifi, she has to be in the basement within 5 feet of our modem. Once she comes upstairs she loses the connection. All of our other devices connect to the wifi on all levels of our house, including her Dad who also got an iphone 4 and her ipod works as well as her brother's ipod and my blackberry. I have tried resetting the network settings to no avail. I have already had our modem rebooted through our internet provider so I know the signal is good (as well as all other devices connect to wifi) I am losing sleep over this and she is quite frustrated so any help would be appreciated. I'm starting to wonder if it's a defect in her phone???

Is her iPhone in a case by any chance? If so, remove the case and try again. How does her iPhone work in free Wi-Fi locations?
Try resetting the iPhone...
Press and hold the Home and On/Off buttons simultaneously until you see the Apple logo, then release. This may take up to 10 seconds. This is the equivalent of a re-boot and you will not lose any data.
If none of the above work take it to an Apple store or AASP for evaluation. She will not be charged folr this and they will suggest a solution if there is a fault.

MacBook Pro loses wifi connection upon wake since I bought a new AirPort Express

Hi. I've been using Apple devices and computers since february 2008 and had no problems until now. I currently own an early 2011 13" MacBook Pro and a PC running Windows 7 and Ubuntu 12.10. Until early February, I used a 2nd gen AirPort Extreme to connect to wifi upstairs, being connected via Ethernet to my ISP's modem located downstairs which provides a weak wifi signal (of course my ISP says it's impossible since their modem is the best on the market), not even compatible with Apple's wifi systems (all other French ISPs modems are compatible with it), that's why I had to get a 30 ft ethernet cable running down the stairs. My connection was lost everytime I went upstairs/downstairs so I bought a new Airport Express to replace my ISP's modem wifi signal and I'm using my AirPort Extreme to extend the wifi network upstairs. Now all my devices and computers have a strong wifi signal anywhere in my house with only one downside: My MacBook Pro (and only it) loses the wifi connection upon wake after sleep and I have to disconnect/reconnect it manually. I didn't bother installing Windows on it as I removed the Superdrive to setup a DIY Fusion Drive a few months ago so I can no longer boot optical medias and I can't know if it's a hardware or software problem. Again, everything was working all right on it until I changed my Wifi network configuration a month ago when I bought my Airport Express.
Can anyone help me ?
Thanks in advance.

Well this isn't making sence.
What is the model # on your extreme?

Mac mini loses wifi connection when using vnc....

I currently dont have an aextra keyboard, mouse and monitor so for short term id like to connect remotely to it. I configured the sharing settings in system preferences on my mac. Im running Mac OS X Lion 10.7 and Im using tightvnc on my windows computer and its having a hard time getting connected to the mac mini. I notice when I try to connect my wifi connection on the mini drops. Can anyone tell me why this is? Any help would be greatly appreciated.
Thanks
Angelo

We'd need a Monitor & KB/Mouse on the Mini, or another Mac to log into it, but you might try navigation to...
/private/var/log folder on the Mac & maybe look at the system.log if you can on a PC.

Mac loses WIFI Connection...

I just start experiencing this problem since I moved to a house with some DSL router but never experienced it when I was using my own NetGear router with a cable connection. My Mac loses its connection every once in a while and I have to turn off WIFI and select the router again. Since I am the only one having the problem people will say its my Mac, but I am not sure. Perhaps because I am living in a city with about 15 other WIFI networks around my be the problem as before I was living in a more isolated area with only a few WIFI networks.

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, sometimes any one of the following can help although, unfortunately, not always - in no particular order:
Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
Change the wifi channel on the router
Create a new Network Location: http://support.apple.com/kb/HT5289
Reboot the router
Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

Apple TV loses WiFi Connectively After waking up from sleep

My Apple TV, software version 3.0.2 (which gives us 1080P btw), works fine, until I put it to "sleep." Later, when I use the Apple TV, it says: "Not connected to the Internet." In effect, my wifi has disappeared from the memory of the Apple TV, and I have to enter the wifi network's password again on the Apple TV.
I have had this Apple TV for about a year; the problem appeared maybe one month ago.
I took it to the Apple Store after Apple Care Telephone Support consulted with engineers. The Apple engineers said it could be a hardware problem, and for me to bring my Apple TV to the Apple Store so they could diagnose it. But at the Genius bar, they put it to sleep and woke it up and it never lost connectivity every time. I suggested that as the Apple Engineers wanted the hardware looked at, why doesn't the Apple Store keep my unit, put it to sleep, and wake it the next business day? The genius bar refused, as the problem did not replicate itself at the genius bar. I told them that trying after 10 minutes wasn't enough. They should try it overnight, as I do (go to bed, try it the next day, only to discover that the Apple TV lost it's connection to the WiFi.
So for now, my work-a-round is that after a few hours, I have to reenter the password for the wifi. I've been reading threads about similar issues with the iPad, but I don't know if the problems are related (technology wise).
Bottom line: My Apple TV loses its connectivity after being in sleep mode for awhile. Nothing to do with the iTunes store or 3.0.2 as far as I can determine; if I don't put it to sleep I don't lose connectivity.

Thank you, Jamie Cox1. However, after rebooting the Apple TV, I lose my 1080P; it goes to 720P and takes about 5 minutes or so to reboot. Then I have to set the 1080P again. The good news is that the wifi returns But it is quicker merely to re-enter my password.
The problem remains: After a while of having the Apple TV in sleep mode, I lose connectivity to my wifi And while I have a complicated password (upper and lower case letters, numbers, and not a dictionary word), it still is quicker to re-enter my password than to wait for the Apple TV to reboot and re-enter the settings for 1080P.
Thanks anyway; if I only had 720P perhaps this solution might be enough - but I have 1080P.
I am working with Apple Care; I have reconfigured my wifi twice with Airport Utility, removed all interference (microwaves, cordless phones), and still the problem remains. Apple Care hasn't solved the problem. The Genius Bar at the Apple Store hasn't solved the problem. Re-booting does find the wifi again, but it takes a long time, and then I still have to re-set the resolution to 1080P. So I just re-enter my password each time.
And that's my update! I appreciate everyone's suggestions. However, the problem remains: after putting the Apple TV in sleep mode, and then later when I want to use the Apple TV, the Apple TV forgets that it is connected to wifi and I have to re-enter my password, or I can take some time and reboot the Apple TV but then while the wifi returns, the 1080P disappears.
Thank you everyone for all your suggestions
But the problem remains
