I did not use 12.04 which was preinstalled very long, but I think the problem did NOT occur in that release. My wireless hotspot is Netwjork 150mbps which is re-branded name for Tenda W268R 4-Port Switch 150Mbps Wireless-N Broadband Router I think. I am using 802.11 b/g/n mixed mode. Now I reconfigured my AP to use only channel 11 instead of auto-select and only mode 11g instead of mixed mode. Distance from AP is about 5 meters there is one corner between the ap and my laptop but nothing changes even if I bring my laptop next to router.
