Windows 7: Windows 7 and Intel WiFi Link 5100

I've been having issues with my laptop and its wifi card for the past couple of months. It's an Intel WiFi Link 5100 and my internet just randomly stops working, other computers and devices still work fine, but on my computer I cannot browse the internet (however sometimes downloads don't stop for some reason). Updated my drivers, turning it off and on does nothing, and I'm pretty sure it's not my firewall but next time the internet stops working i'll make sure.



When I say it randomly stops working I mean I'll turn the computer on it will work for a bit then just stop then a little bit later it will work. No other computers or devices experience those kind of pulses here.

What AV and firewall are you using?
Some reported problems with AV and wifi.

using AVG antivirus, which gives a bunch of problems i'm finding out

I use MSE for my AV(free) and have had no problems with it.
Avast is another good free AV.

AVG is not causing it, disabled it and internet didn't come back until I rebooted the computer. I had a similar problem before but it was caused by my computer going into hibernation (it was actually an intel driver issue) and when I would wake it up the internet wouldn't work until I restarted. But it's different this time because it will do it at random times without going into stand by..

Resetting the computer fix it, everytime i've tried it at least

Just out of curiosity are all your drives up to date.
Go to manufactures site to get the latest updates on drives.
Have a great week-end.

Might be drop-outs in your internet connection...i've got an intel 5100 aswell and sometimes it does...

Check if transmission is set at max in the properties of your card in the device manager, then in power plan settings if it is also set to max performance

Check your power options, make sure you don't
have it set to: Allow the computer to turn off this
device to save power.

First thing I did was check the drivers and they were. Already have done what rvb said in the past, and i'll check on what NoN said when I get off work
