If you've got to the stage of using the reset button, you'll probably have wiped all the specific settings you had for wireless channel, security etc. Make sure the connecting wireless stuff also has those settings removed.

If something odd is happening, start by configuring the system without any security and stuff. You can add that later once you have basic connectivity established. The only thing worht playing with is the channel, as that can conflict with other stuff in the house. If your router has been moved, as the modem moved, make sure it isn't somewhere where the wireless can't get out or be seen by other appliances - higher is better and away from electromagnetic radiation sources.
