Title:
NM randomly loses wireless connection, both Wi-Fi and wireless
broadband -- Atheros AR5001 ath5k
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: network-manager
This has happened with very many versions of Ubuntu. The problem is
that sometimes, like once a month, my computer loses the wireless
connection. Then nm-applet starts trying to find the connection again.
After that wireless networking doesn't work, until it does. I don't
know why it starts work again, but i have rebooted Ubuntu until my
wireless networking starts working again. Maybe something in the boot
process goes sometimes wrong?
It also does the same with my mobile broadband. Mobile broadband and
wireless networking don't usually get crippled at the same time.
Sometimes the problem also occurs in a case in which the wireless
networking or mobile broadband has been working last time the computer
was on. On the next boot it just doesn't work.
I don't know is the problem in nm-applet or network-manager. I guess
it is in network-manager. The problem could also be in hardware
detection or kernel. Anyway, nowadays lots of things depend on
Internet connection and I can't use Ubuntu for working purposes
because I cannot trust my Internet connection just works.
* I'm using Ubuntu 10.04.1.
* My network-manager is 0.8-0ubuntu3.
* I expected my wireless networking to work.
* Instead of working, nm-applet didn't show any available wireless networks.
I don't exactly know how to reproduce the issue. With time it can be
reproduced for example with Ubuntu 10.04 and Acer Aspire One 3G (model
no. ZG5) and using it.
