[SOLVED] Spontaneous wifi device disassociation.

[edbarx]

I would like to know what Broadcom wifi users do when their computer loses connection after a couple of minutes of network inactivilty. The disassociation is recorded in dmesg. Running iwconfig on a broken connection restores it.

Code: Select all

# iwconfig wlan0 essid mycoolessid

Added Later:
I have been given enough information, thanks.

I suspect that you would increase your chances of getting helpful information by posting which broadcom interface you are using. Even the Debian version might be useful information.

If it one on this Debian Wiki page then it might be related to power management of the card and you might try the solution offered on that page under "Known Issues", "Frequent disconnections can be ..."

You could also try searching with the keywords, <substitute whatever the broadcom name is> and "disconnect"

I agree with wizard10000

We could identify the device positively with:

Code: Select all

# update-pciids && lspci -knn | grep -iA2 net

You could also try switching to the (vendor-supplied) wl driver — some users report a better experience with that.

See https://wiki.debian.org/wl for the method.
