Larry, Thanks for the response. I am coming to the conclusion that it is the transmission strength of the wireless. However, I am no expert in this. Have put the old router downstairs and maintained a connection for the rest of the evening. Clearly it would appear that the laptop is not picking up the router's signal as effectively as my old laptop. Only conclusion since both laptops in the same location and 2 different routers tried. The 20db reported in iwconfig by mac80211 is not the actual data, is the signal strength please? I can see the signal strength change upon repeated calls to iwconfig and downstairs even when seemingly "out of range" and failing to ping anything, it still reports a signal strength of above 50%. Since there is nothing to fix per se with the driver, is there anything further to interrogate to eek out any info on what is going on when the network seemingly drops? Cheers for your help.
