Firewall is active from the setup of my wireless router.
cant access beacon interval on my router.
No tweaking on my wireless router since i've installed Ubuntu 12.04, a few months ago.
Distance is less than a meter

All other devices connected (Windows computers, tablets, laptops) did not experience disconnecting.
