internet speed here in the US? the reason why i posted this is my wireless shows low signal and flactuates from 4Mbps - 30 to 54Mbps.. does it affect internet usage like opening sites that has graphics?
802.11g advertises 54Mbps, but in reality, you only get about half that once overhead and other issues are over and done with. As long as your pipe to the internet doesn't exceed your wireless/network speeds, it shouldn't be a problem except within network.
How quick your internet speed is depends on your connection. Check what you pay for, it states the speed (or maximum speed anyway). I doubt it's more than the 4 Mbps you said was the low end on the wireless.
