wifi problem

[kejzak]

Hello its my first post.
So start descibe it my problem. When using wifi at home, no problem. I notice scan less network compare window but till I using only my wifi at home not so worry me. But now when I leave home, got problem.
sometime I see wifi network, i log in and after few minuts lose connection. Sometime after reboot even one time doesn't see any wifi conection , but smartphone have all the time. I am sure is not problem with password or smth. If switch on Windows discovery at least 15 wifi networks, and works fine if connect

Any ideas?? please help

1.may be the driver is wrong, ieee 802.11 network is a little different between Asian and the USA, you can install ndiswapper to make the driver for windows work for linux
2.may be you use the wrong input maction .

Welcome to the forums. Yes often a later kernel can fix problems.
