Problem: Wireless network is connected, internet drops from time to time
Linux Mint 14 Nadia, it connects to router (ZTE) - wireless is connected all the time, also there are no driver problem(product: AR9485 Wireless Network Adapter
, vendor: Atheros Communications Inc.), however, in random time, internet suddenly stops working. Even connecting to the wireless router is not possible during internet "blackout". And all of suddenly starts to work again, all by itself. Then drops again etc. At the same time, the internet is working fine on Windows PC.
Solution is - add static IP address.
That was temporary fix, fix was plugging to network cable.
