Got confused here.. I've been getting the full 54Mbps but with anything less than very good signal strength in fact today got very low for the first time whilst being on low for the average day. I'm using the Netgear USB wireless dongle 108mbps. Should i be worried cause really the speed hasn't dropped from 54Mbps whilst the drop in signal strenght... The browsing/downloading doesn't seem bad too for low/good signal..
