I spent about 4 hours trying to get this damn Netgear WG311v3 to work this afternoon with my new install of Windows 7 64 bit. Either there’s an issue with it working with > 2gb of ram, or it’s an unsigned driver, or both. Anyways, after several hours of furious googling and finding nothing but people talking about the problem, I found an excellent writeup on the solution here. It works! I’m going to quote it in case it goes down, as this seems to be the only solution currently. The files you need are here. In short, you are installing the Win7 Netgear drivers, then “updating” them from inside the System Manager with an old unsigned Vista 64 driver (driver linked to above) for the same wifi chipset (Marvell 8335). Relevant information is after the cut:

Ok, well I had some troubles getting my Netgear WG311v3 working in Windows 7 64-bit with more than 2Gb of RAM (I’m using 8Gb). It would run fine using official Netgear v3.1 drivers if I only had 2Gb of RAM, but I was getting sick and tired of having to turn off, then restart my computer to add more RAM to play games at their potential (but then also not being able to play online unless I got my network cable out). So I searched for a fix and never really found anything that worked. I ended up fixing it myself by combining a few answers. Here is how you too, can get your WG311v3 working with more than 2Gb of RAM.
First you’ll need to download and extract the Marvell v220.127.116.11 driver.
or got to THIS page and go to Libertas 802.11a/b/g Wireless (MRV-8335) and select Version 18.104.22.168 beta under the headingWindows Vista 32/64bits
Unfortunately these drivers are not signed so it will ask you if you really want to install it, so click yes.
There is an alternative though. It is called ReadyDriverPlus and it pretty much presses the F8 button for you and selects the Disable menu automatically
If Microsoft ever makes it so you can run unsigned drivers without having to stab the F8 key at boot, leave me a note so I can update this. I am shocked that Netgear sold this WG311v3 card into December of 2009 without any functioning Windows 7 64 bit drivers. Hope this helps.
