Windows 7: 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 Windows 7, 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.

whoever is getting limited conectivity, we need more information to see what is wrong:
goto command prompt type

ipconfig /all

This will show what IP address it is using, and your gateway / DNS servers
make sure the gatewat is on the same subnet and you can ping it.
if you can ping the gateway, check if you can ping something on the internet
like 74.125.87.104 which is google.com. if that works then try pinging Google

Sometimes if you have norton or eset running they can distrupt your network or DHCP, do you have any firewall or protection solutions? sometimes protection solutions such as norton or eset have a hidden firewall feature that is still active even when disabled.

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.
