    Ok, I think the wireless ability on my router is on the fritz. This all started happening when I upgraded from 1.22 to 1.23.

    I want to basically "reformat" the entire router and make sure that I rule out all possibility that the firmware is to blame.

    How do I do this?

    Well, I suppose you could do a thorough NVRAM clear via the Tomato GUI. Then, during the reboot window (the nvram clear will reboot the router), you could flash to a different firmware using tftp. Then, there should be no trace of Tomato left.

    In addition to admin->config (clear nvram, thorough), you could power off the router, press (and hold) the reset button, power on, and hold the button for 30 seconds before releasing it.

    I got that from DD-WRT's site. They seem to be obsessed with ways to boot, safe-boot, hard-boot, clear and boot routers. There seems be a variety of ways to do it depending on what is desired. I never understood how they differ, etc.

    I also saw some discussion there and doing things multiple times, power resetting between each one, etc. Doing it before and after flashes.

    I tend to do that 30-second reset a few times before flashing. I clear NVRAM after flashing.

    I have a wrt54gl but haven't tried wireless after flashing to 1.23. I'll try it and report if I have any trouble. If you don't hear from me it means there was none.

    I don't think it's the 1.23 update. Otherwise thousands of posts would have appeared. I think if I place the router next to the power strip, it kills the signal... I've never even heard of that.

    I thought you can place a router anywhere in a small house?,,, guess not

    Can I trust that cool feature in Tomato that scans all of the channels to tell you which is free?

    it tells you which channels are in use. It doesn't tell you which channels have interference.

    Try 1, 6, and 11 - use the one that works best.

    I've been running wrt54gl with TKIP/AES without problem.

    I've read a couple things where people's routers became flakey and it was the power supply going out (supplying low power).

    It's hard to believe that's the problem, and it's just a coincidence it happened when you upgraded. But, I know Linksys's power supply looks pretty cheesy.

    Very true. I had to replace the power supply twice on my WRT54gv1.0 twice. Could very well be the problem.
