My wife and I live in a newish flat and immediately below us in a smaller one bed flat lives my elderly mother. We have optic fibre BB upstairs and with a well positioned 'NetGear' range extender, my mother has a sufficiently strong BB signal downstairs for her needs, that is until this week. Something has changed and her signal is quite dreadful and I suspect it is permanent caused perhaps by one of the many high rise developments going up, plus of course the increased demand for BB due home workers. I have alternated all of our computers and the problem is the signal not the computer. I would like recommendations for boosting her BB reception over and above our existing 'NetGear' extender which seems no longer able to cope. I know a little about power line adapter but surely this will not be suitable for our needs as I understand a continuous electric domestic wiring installation is needed and we are in two separate flats. I really don't want to go into a 'Mesh' installation because of the cost, the setting up difficulty (?) and mindful her needs are hardly demanding - 3 hours per day total to read the news, e mails to friends but no sapping downloads or video games. A wired connection from our router will not be possible for many reasons, it really has to be WiFi. Help !!
