Thread: Wireless network connection very unstable.

i'm having troubles internet connection in ubuntu right now. well, few actually.

first, when compare speeds between ubuntu , windows, i'm getting double link speed on windows on ubuntu.

second, internet connection periodically drops. when i'm downloading large file or putting large load on connection. can't connect internet few seconds , connection drops , tries reconnect (which after few seconds).

i've tried few fixes i've found around google none of them have helped me. wired connection fine router in place can't use wired default connection. wireless connection 1 problems.
