> Did you try reseting the router? Yes. > Did you try changing channels? I must confess I didn't know this was possible. I don't have the instructions for the router anymore. Is this easy to do? (Thanks to Linda for this suggestion too.) > Do you see the same problem when the connected via an ethernet cable? I don't have an ethernet cable to hand, but was intending to try this when I get hold of one. > Does moving the router to a new location change results? I'm going to try that too! Thanks for these suggestions, I'm hanging my head in shame at not trying these latter two before asking... All the best, Colin.
