I have problems to connect via Wifi with my Acer Aspire V 13 V3-371-39MA for several month. The strange thing is, sometimes I can connect and the conection would stay for the whole day...on other days it's not possible at all or isn't working for few hours and suddenly I can connect. In the beginning this problem wasn't so bad and mostly everthing worked out fine, but now I have this problem whereever I try to connect and I tried it with several routers already. With a wired connection the internet works out very well.
I was already making some research and from what I red I assume that it has to do with the wifi driver. I found out that my network adaptor is an Atheros 9462.
That article might be similar to my problem, but none of the commands really worked out ( it could have been my fault, as I'm not that much into ubuntu at the moment): Atheros AR9462 WiFI very unstable & package loss
Is there anybody who is able to explain me in simple words how I could solve my problem?
