Is this wireless adapter the one installed by factory or did you install it later? If it is the one installed by factory, we recommend that you contact your computer manufactorer to see if they have any updates that might help you resolve this issue. What Operating System are you using?
What could also be causing this issue is your antivirus. Some antiviruses configuration can impact from time to time with other drivers. Test your connection with the antivirus disabled. *You need to take extra precaution when testing your wireless adapter while you have your antivirus desabled.
its a self build and I right now I use the one and only Intel driver, the speed is fine now though, I dont use Anti-Virus, Im an IT technician and know what im doing, i have other means of protection such as Private Firewall and Winpatrol with some on demand scanners and Malwarebytes Anti-Exploit...no real-time scanning on this machine so cant be corrupting the intel driver
I havent had a BSOD since putting intel driver in , but give it time
Then, let us know if the issue comes back again. We will be more than glad to assist you.
I also had lots of BSODs with the 4965AGN using the driver that comes with Windows 7 x64, both on my laptop (Core 2 Duo/Intel 965) and my desktop (i5-2500k/P67) using a PCIE to MiniPCIE adapter.
I can confirm that the BSOD is gone with the latest Intel driver (from 2010). I still have problems, though. After being on for a while, especially after resuming from standby, it gets this weird thing where it alternates between a second or two of 100% packetloss and a second or two of it working, back and forth, repeated until the PC is rebooted. It makes a graph that resembles a comb in the task manager. TCP throughput is cut to about 3-4 MB/s (as it is doing a ton of retransmissions), which is still more than my internet connection (which is probably why I did not notice it before), but about a quarter of what it gets when everything is working fine.
That issue is what I came to see here... if I can't find anything, I will post about it.
As for Aleki-Intel's advice to contact the laptop manufacturer: It would be nice, but the 4965 is quite old (though still useful), so any laptop that had it as original (as mine did) would be just as old, and I don't know of any laptop manufacturer that doesn't drop support for older models like a hot potato.
