I saw there was another thread on this but with out a solution and I didn't want to piggyback on it. Not sure if my issue is 100% the same. My wireless connection drops when I try to download a file (ie, google chrome). Once it drops however, it will not reconnect until i reboot.
I am using a Dell Inspiron mini 12 with the following adapter: 03:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) 03:00.0 0280: 14e4:4315 (rev 01)
