Betreff: [DNG] Wifi dropping ramdomly
Hi,

My wifi connection drops randomly. It can sometimes run for days.
Other times it may drop within hours of a reboot. There seems to be
no pattern to when. Initially rebooting seemed to be the only way to
get the network back. Under xfce4 disabling the wifi and/or network,
then re-enabling them had no effect. After many google searches
I finally found at:

https://askubuntu.com/questions/26054/how-to-restart-wifi-interface-without-rebooting-it-drops-connection

I now have the alias(zsh):

alias reload_network_module='sudo modprobe -r iwldvm && sudo modprobe
iwldvm'

to re-enable the wifi. So far this has restored the network connection
without having to reboot. Strange as it may seem, the wifi connection
has stopped dropping as frequently since reloading the iwldvm module
this way.?? FWIW

Not sure if this is a hardware or software or firmware issue. No other
devices/systems are having this issue on the same wifi network.

If anyone has any advice it would be appreciated. Since I have a
workaround it is just an annoyance.
