Intel WiFi 4965AGN: limited access

Lots of problems reported with wireless adapters on here at the moment. As suggested elsewhere make sure you have access to a copy of the latest Vista driver for your wireless adapter to install into Win7, as the WDDM standard drivers (if available) often have poor performance.

WiFi drivers seem to be a bit of a black art. I found out that my desktops Linksys Card actually uses a Broadcom chip set. By installing the latest Broadcom driver (rather than using the ancient Linksys driver) my WiFi performance increased by about 30dB!! (RSSI has shot up from about -85dB to -55dB). I t also seems to be fully compatible with Win 7.

I have the same adapter and it works just fine.
Zepto 3215 1,7 dual core 2 Gb ram.
As i remember I got the driver at windows update - but I am not shure.

If you have a trouble with WiFi connection than you have to only change channel of your AP. Use lower than 11 and everything will be working.

Hi all,

I have the same adapter, and it has been working fine on Windows 7 until (I think) the latest Microsoft Updates.

The way I have been working around the problem is uninstalling the driver before shutting down. The next time I boot, windows successfully installs the driver, I enter my network key and all is well. However if I don't uninstall then I only get local access!

I have just updated my installation from build 7137 to 7229 hoping this would cure my issue (connected to internet during install), but no such luck

Every time I Boot to Vista I connect straight away...

Any suggestions?

Just found another work-around: I entered a static IP address, rebooted and it connected straight-away

Hi Guys
I have the same problem and adapter...
I tried connect to my acces point with static ip but nothing change and then i tried reinstall the driver but nothing change

please help me

Hi Nathe Fellow,
I was a bit premature leaving my previous post, it must have been a fluke that it worked 1 time only! What I resorted to in the end was uninstalling the driver prior to shutting down, then the next time I booted up, windows installed the driver and I had to re-enter my key.

Anyway, this continued for a few days and then it miraculously cured itself! I am back on DHCP and not had a problem in a few weeks!!!

Good luck

What Win 7 build are you guys on? There was a big improvement for me in network connectivity and discovery with build 7232.

I have a Lenovo X61t that has the 4965AGN and it works great, wired or wireless. If I have both on, it uses the Gigabit (they both connect to my 3Com switch). If I yank the wired it switches to the wireless automatically. I also did have it on when installing, although 7232 x64 was an upgrade from 7201.

Clarification: the wireless connects to my Verizon DSL router, which in turn is wired to the switch.

Also try disabling then re-enabling the network adapter. Sometimes forcing the DHCP server to give you a new address works. You can do this in the Network & Sharing Center, click on the connection, then on Disable in the connection properties. Once disabled, click on Troubleshoot Problems and follow the instructions.
