 Posted: Fri Jul 11, 2014 4:53 pm Post subject: Tp-link Wifi Adapter Problem (Solved) |
 |
|
I'm having some difficulty getting my usb wifi adapter to perform well. The same hardware booted into windows works great but in linux I'm seeing massive delays. Hopefully I've just configured something wrong. I'm using wicd although I've used wpa_supplicant and get the same results. A couple screenshots capture the problem:
