wifi network down randomly
Hi, i'm using a dell xps 13 l322x, with on-board wireless card Centrino Advanced-N 6235 (Vendor ID:8086, Device ID:088e) on wlan0. The wifi can usually work at least in the first a few minutes when I start the system, but at random point of time, the wifi would be down. The router i'm connecting to is NTUSECURE. This problem has been replicated on liveCD as well as connecting to other wifi routers using the same machine.
i notice the line "iwlwifi 0000:01:00.0: fail to flush all tx fifo queues Q 0"
I'm not sure if that's what causes the failure.
