USB can be iffy on some PCs. If I were to tackle this one I would have to know more about the host PC and why a normal PC Card wasn't used.
Also, the choice of machine drivers and antivirus can factor in. This can be very upsetting to folk but I do not expect Netgear to own the issue.
Let's hear more and how about a Web Speccy to read?

I own a Netgear WNDA3100v3 N600 USB Network adapter because the router is too damn far away for me to use an ethernet cable. Basically, this thing is fine for just browsing the web. But when I try to play games, the ping ******* destroys my ***. I'm talking jumps from 20-30ish to over 1000ms around once a minute-ish. Because of this I've been pretty much barred from playing any game at a level even close to competitive. I've spoken with Netgear support 3 times now. They're useless. First time the lady was supposed to call me back and didn't. Second time the guy got my email wrong (I told him to just send me the flowchart he was using), and the third time they finally got my email right and it was just some links to ****** articles with vague troubleshooting steps that I'd already seen multiple times. So that's why I'm here. I can provide logs where I ping my router or the logs of various ping tests for proof if needed. I'd seriously prefer to not have to buy any new devices, so if there's any way to make this thing stop with the spikes, that would be preferable.
PS: I've tested the ping of multiple other devices on this network to see if it was on my ISPs end, and they were fine. No spikes.
Thanks in advance!
