    I've read the majority of the "disconnect" posts here, but am still at odds end, and since there seem to be many very knowlegeable people here, I'm hoping that you can help me troubleshoot.

    Setting: Appartment Building, WRT54G router, WEP on, set to mixed mode, B&G.


    Frequent losses of signal from 2 different laptops (one b, one g). When the signal is lost, it does not matter where the laptop is located in relation to the router. It can be in the same room, within a foot of the hardware. To make it re-aquire a signal from the router, you have to change the channel on the router. Usually after 2 or 3 channel changes the router is re-aquired by the computers. Lately it only seems to re-aquire on channels 1 and 2, and 10 and 11. The channels in-between never re-aquire.

    I had previously used an SMC router, and had a similar disconnect problem. I actually thought it was the router, so I trashed it and picked up the linksys.

    I have tried changing the location of the router, with no change in symptoms. Attached a hawkind directional antenna to one of the antenna ports, again no change in behaviour.

    Installed HyperWRT firmware and maxed out the output. Again, no change.
    Changed the beacon interval from 100 to 50, with again no change.

    Now I'm at odds end as to where to go next..

    maybe it is a 2.4ghz cordless phone. becasue everytime that i use my cordless phone the network just stops completly. the really bad thing is that the phone bonds the whole specturm so i can not change to a differnet channel on the router.

    being an appartment building, there is obviously a chance that there are 2.4Ghz phones around, but this seems pretty extreme behaviour for phone interference. I've seen lots of these routers work near 2.4Ghz devices at colleagues places.

    If its phone interference though, would it still have such an effect even if I was 3 feet from the router with the computer?

    Thanks for the comment though!

    Maybe you could use Netstumbler to do a site survey and track down any interference.
