    Hey all,

    I've got two WRT54G routers. A v4 and a GL. With DD-WRT, HyperWRT, and stock firmware, I have bad disconnect/reconnect problems. This is with both an Atheros based b/g miniPCI and an Intel based b miniPCI in my laptop. I'm fairly new to the WRT scene and am disappointed I can't get this figured out.

    I can stay connected for a few hours, then a disconnect occurs with no ability to reconnect for several minutes. I can reboot the router, shut the wireless card off/on, etc, and sometimes I can reconnect immediately, but sometimes not until several minutes later. The different routers with different firmwares, with WPA, WEP, no security, etc, all exhibit the same problem.

    What the heck? I've been thinking this is a Broadcom to non-Broadcom problem? Or is the WRT54G just not that stable with any firmware? Previously I used an Atheros based Netgear MR814 wireless router that was ridiculously stable with only very rare disconnects.

    What should I try next? Disable DHCP? Transmit power is the defalt 50% so this shouldn't be overheating, right? I had been thinking of buying a BCM94318 miniPCI off ebay, but don't know now since the Intel 2100 b card had problems too.

    I've read countless posts, and many people found WPA to be the problem. No such luck for me.

    Thanks, Doug

    Yikes, looks like the community is stumped. I'm just gonna buy a Broadcom miniPCI off ebay and see what happens. I'll replace the .11b adapter in the second lappy and go all .11g. If the routers are still flaky, I'll move to some other brand. Sad, since the configurability of the WRT with HyperWRT is just so awesome.

    Sounds like something is interfering with your wireless signal. Something else you might want to try

    - using diff. freq.
    - upgrading to the latest dd-wrt firmware
    - upgrading to latest driver if there is one

    I hope it helps

    Major stupid on my part. I did not try a different channel. I have a 5.8 gig cordless phone and rarely use my microwave so didn't think of this. Plus my card and router may just work better on a diff channel, we'll see. Site surveys show no other WLANs running regularly nearby. But my router is against a wall with someone else's kitchen on the other side, so possibly their micro is interfering.

    I ran the latest DD-WRT (about 2 weeks ago) with the same results, so not that. I had the latest Intel drivers when using that card, and a late Atheros driver for the other card. Late Atheros drivers are hard to find.

    Good ideas, thanks.
