Well wideboy and Ralph I have spent the greater part of today trying to fix the problem, causing a new problem on the way.( fortunately resolved) Isp suggested likely to be Mercury USB adapter but thought firmware update might well be appropriate so I will phone etec tech support tomorrow have number, laptop helpline thinks router faulty
Wideboy I was very interested in your finally comment about a connection with a windows update. It would not be the first time that happened and I am pretty sure that all these problems started soon after an update. However, I am always being advised to download them all and do not usually get any support for my doubts about them
