Once you've manually cycled the power and the laptop connects, do you have any further problems? Will the laptop re-connect if you shut it down and re-start? It's normal to have to cycle power and bring equipment up in the correct order to get things working.
You didn't ask about your phone service, but your packet discards on the downlink are atrocious. Do you get similar results from both the wired computer and the laptop? How is your call quality?

I hope one of the networking experts jumps in to address your primary problem. It's not normal to have to recycle the router each time you need to establish a wireless connection.
In the meanwhile, you should still address the dropped packet issue. It has improved, but is still marginal. If you plug your wired computer directly into the modem, does it get any better?

The wired computer is hooked directly to the WRT54GP2 router. Are you saying I should unhook it from the router, plug it directly into my cable modem, and then run the "testyourvoip.com" test?
Yes, just as a test. If things suddenly get a lot better, it suggests something is wrong with your primary router. If things don't get better, it suggests that you should have a talk with your ISP.

This certainly suggests an issue with your wireless router/adapter. While we're waiting for the networking experts to dip their oars in the water, have you tried a hard reset on the router? Are you running any intensive data transfer programs?
Are you running any intensive data transfer programs?
Not "download", but I did recently transfer a about 30 TV programs from my TiVo to my computer. The TiVo is hard wired to one of the three ports on the WRT54GP2 router, as is my computer.
