I am frustrated. I have a WRT54GL Wireless Router and I used to have speed of 54 Mbps at all times... now I struggle to get 36, and only operate at 24 most of the time. Could someone please help me boost my speed? I have tried: - Router power cycle - Modem power cycle - Calling Comcast, who said the modem was doing great - Reseting the internet signal What else can I try??
