My laptop seems to be blocking other computers when connected to home DSL/cable routers via WIFI.
The problem is reproduced at several locations with the same laptop: other users complain that they are not able to connect to the WiFi router anymore, and when connected, they experience extremely slow traffic. On my own laptop, everything seems to be fine, apart from occasional disconnections followed by difficult re-connections to the router.
The laptop is an HP Pavilion DM4 with Ubuntu 12.04. The wifi adapter is handled by cfg80211.
This is extremely annoying, and I cannot find any reports of similar problems on the Internet.
By any chance, could my problem be related to this? http://intel.com/support/wireless/wlan/sb/cs-006205.htm
