Hi guys,
I have a wireless usb adapter:
BUFFALO INC. (formerly MelCo., Inc.) WLI-UC-G300N Wireless LAN Adapter [Ralink RT2870]On booting into linux after a restart from windows, i have an issue where it seems to not pick up/connect to any wireless networks (using networkmanager with gnome).
I can connect however, by simply restarting networkmanager.
I don't know if this has anything to do with the usb driver (not resetting the usb adapter or something?), or if its a problem with networkmanager.
If i reboot once the network is working in linux (i.e. reboot again into linux without booting into windows), then i have no further issues, which seems to suggest an issue with the state of the card?
If it was a problem like this, then i don't know if/why restarting networkmanager would 'reset' the state/driver?
(I don't know if the problem occurred due to a recent kernel update, or recent NM update, as arch had not been updated in a month or so).
The logs from networkmanager both seem to show the same initialisation, but then one seems to just stop before connecting:

Any ideas?

Ok so ignore the above about networkmanager.
A simple ifconfig wlan0 down/up allows me to connect to the network.
If a solution to the above problem doesnt exist. Would it be possible to implement a workaround, for example by performing an ifconfig down/up before network manager starts somehow?
That way i wouldnt have to manually perform the operation after working in windows.
Cheers
