what could be causing repeated internet connection dropping on a wireless network (the wireless does not disconnect), which can be momentarily fixed by disconnecting and reconnecting in 14.04? Here is the wireless info list http://pastebin.com/ZgGxQ9qE

I am using a USB TP-Link TL-WN821N wireless adapter (Realtek rtl8192cu).

  • @Pilot6 - hi, I tried that command but it prints nothing on the terminal, if I type just lspci -knn there is a long list.

  • @Pilot6 - yes, it is a TP-Link TL-WN821N. But the wireless connection does not disconnect, I can ping the router at its ip address.
