I don;t know what is going on, but sometimes I receive full speed @ speedtest.net (approx. 80 Mb/s) and afterwards, a few minutes later I receive approx. 20-24 Mb/s.
Don't know why the speed is so different.
Moreover my TP LINK 841N router is freezing very often (need to be rebooted to start working again). Don't know if it is connected with Intel Dual Band Wireless N7260, but before I bought T440s I didn't have such problems.
Any news regarding new updates?
