airport extreme wifi issues
I have recently bought an airport extreme as I was told this will significantly improve my wifi reception in my house. Sadly this has not been the case and I have been trying all manner of positioning and channels to get it to work. Is this a fault or is there another setting I am not sure about? The wifi works when you are within 10-15 feet and at the same level. However if you walk one flight of stairs to my bedroom (even though the router is immediatly below, through a plastic roof) the signal is lost. Any suggestions please?
