I bought NetGear WNA 3100 wireless usb adapter(https://www.netgear.com/support/product/WNA3100.aspx) for my desktop, It was working just fine until I reinstalled my Win7 which made it to work in some funky way. It stopped detecting my main router and only it, if I try using my cellphone as an access point, it sees it and I can browse Internet no problem, it detects the router of my neighbor, although it's further away than mine, which is like in the next room. And the funniest thing it detects my main router no problem if I connect it to my laptop. So the only time it chooses to ignore the main router is when it's connected to my desktop. I tried:

Downloading newest drivers from NetGear

Connecting adapter to all 6 USB

Reinstalling Win 7 2 times

Resetting both NetGear adapter and main router multiple times

Looking for similar cases in Internet

Do you have any ideas how to fix it?

    Not possible, it was working before like for 3 months in this very apartment. Unless I became the aluminum. And it detects everything else, like my cellphone, my neighbor's rooter in the house next to mine and the main router as well, when I connect it to laptop.

  • This case=>superuser.com/questions/1065250/… is surprisingly similar to mine, unfortunately I have no idea where on Sagem F@st 1704 port forwarding page I can change 802.11b+g+n modes.

So, I connected my laptop to my router via LAN cable, and did this: enter image description here

Don't ask me how it works, I have no idea. If it helped me it might help you.
