Recently bought this in the hope it would be an improvement in the range of my reliable HH3. What a disappointment. The range is nowhere as good as the advert says, in fact its only a smidgeon better than HH3. 1 exterior wall and it will barely reach 50 ft. As far as I know I've done all the checks and its no better. Any help would be appreciated as its a waste of £60 so far.
Send it back and spend your money on a third party VDSLModem/router that has external aerials. Any router with internal aerials such as the Homehubs will never give great range despite what the adverts say.
