WRT54G seems to periodically stop transmitting

    Hey Guys,

    I have a WRT54G running sveasoft firmware off of a cable connection. In the house I have a Dell WinXP tower and a Dell XP laptop.

    The laptop was previously connected without problems to an 802.11b network at another site for months.

    The problem we're seeing is that the wireless connection off the wrt54g will be fine for awhile, then suddenly kick out on both laptop and tower simultaneously. The windows wireless network search won't even show the SSID of my wireless network as an available network to connect to.

    But if we plug into the wrt54g with a cat5 cable, the connection is fine.

    Eventually, the wireless comes back up on its own.

    Rebooting the linksys doesn't really seem to clear the problem (sometimes it does, but that could be coincidental).

    Any idea what this could be?

    When I first installed the sveasoft firmware, I boosted the wireless signal strength up to about half the maximum (the tower is in a bad location, so I needed to boost the signal). Is it possible something is overheating in the antenna setup of the wrt54g because of this?

    Any chance of interference? (2.4GHz cordless phones, microwave, etc?)

    So you're running at about 100mW? I've never heard of this problem (although I don't claim to read all the forums) and I know people have run at even higher power without problems but then again it is a considerable increase. You don't have the router sitting on another electrical device (or vise versa) do you? (Can greatly increase the operating temp) Can you run at a lower TX power for a while to see if the problem improves?

    Good luck.

    The only cordless phone we have is a 5.8GHz one, and this occurs at times our microwave is not in use. Of course, we're in a block of condos, and there are other wireless networks right around, so it IS a possibility.

    As a precaution, I've changed the wireless channel that the router is transmitting on. Maybe that will make a difference.

    It was 125mW (I wasn't able to check at the time of posting, but have now). I've dropped it down to 80mW, which is the lowest I can put it at where the tower will still get sufficient signal. Maybe that will make a difference.

    It was also on top of a stack on Linksys devices (the cable modem and an unrelated voip router), so the temperature thing COULD be a concern. I've moved it off to the side as a precaution.

    Thanks for the helpful suggestions, and I'll update as to whether they have had an impact!
