I am trying to simplify my life by switching to Clear G4 internet. I bought their refurbished Home Modem (has no WIFI) and connected it via ethernet cable to a Netgear WIFI modem/router. My Imac has very good connection up to 7 or even 10MBPS, but both laptops: MAcBook and new MacAir WIFI performance is very spotty and unstable. It is the WIFI signal that I am concerned about, but once connected to Wifi the G4 signal also varies quite a bit. All computers are on the same desk, so there should not be any difference in reaching the WIFI signal. Can anyone explain what is going on?
