dmesg

I'm on a Dell Inspiron 15 7548 and all of a sudden no more wifi. dmesg show a nice call trace. 


ethtool -i wlp7s0 | grep firmware
firmware-version: 21.302800.0

lspci -v | grep -i wireless
07:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)

(I also own a Dell Latitude E7450 and the same symptons show: internet randomly is unavailable, even though I still have the wlp*s0 interface and ip addr still shows having an ip address, but not able to ping any local or external ip. But on this latitude I get no call trace in dmesg or any message at all. This laptop uses same kernel and exactly same wifi card

lspci -v | grep -i wireless
02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)
)
