|Just for extra info, before the number of channels increased above 11, for minimum overlap 1, 6 & 11 were favoured:|
Is the computer further away from the router? Look at signal strength - sometimes a surprisingly small movement of the router can make a lot of difference.
This freebie Wifi channel scanner gives the channels used - avoid being on or near the same channel of a nearby strong signal.
Always pop back and let us know the outcome - thanks
