So I’m going to copy paste what I wrote on a Toms Hardware forum:
"So I played around with it some more last night, and still no luck.
I have tried manually connecting and inputting all the details to try and create the network (Tried TKIP and AES too). Still nothing, but instead of saying the password is wrong it just states that it could not connect to the network.
I have also tried changing the password to something else and then connecting. Other devices worked. PC wireless did not.
I am going to try and set the router up with no password at all and see if I can connect. I’ll have to do this in the small hours of the morning as to not piss off people in my building.
If it still cannot connect does that mean there is an incompatibility with a Linksys routher and a TP-Link / ASUS wireless adapters? If so that’s absurd.
Will report back."
Then I **think **I fixed it:
"So I think I may have “fixed” the issue somewhat.
I got so pissed off that I turned off the password, but still couldn’t connect. I then moved the whole PC round every single room in my house, and pretty much in every corner.
I have no idea what is so special about my kitchen, but the WiFi card loves it there. I then switched to passworded and it still worked!
So for some bizarre reason, the area directly next to the router but on the other side of the wall is not the best place for my PC. The new location is around 5 meters further away.
Anyone heard of something like this? Interference? Stability issues? Act of a supreme being? I’m not sure.
I guess you could say this is solved…"
