Help needed w/ WRT54GS

    I have problems where the connection drops completely for a while and then comes back. I have:

    * WRT54GS rev 3, just installed Hyperwrt_GS_Thibor-120106.bin last night. I followed for the most part this procedure: http://www.hyperwrt.org/forum/viewtopic.php?id=885, except for the initial part where he loads the first firmware ( he has a G, I have a GS). But did everything else exactly. In fact, I did the erase nvram; reboot thing twice, cause I'm anal. My router is located on the 2nd floor in the center of the house. It is my only router and is installed behind my Comcast cable modem.

    * WMP54GS card in an XP home machine on the first floor, almost directly below and to the right of the router, with latest drivers.

    * WPC54GS card in an XP pro laptop, with latest drivers. Location varies.

    * I have a PC wired 100/full to the router that never loses connectivity.

    I also have a two-handset, 2.4ghz Uniden phone system located on the first floor.

    I have the router set to all defaults except:
    - transmitter output is 67%
    - Wireless Mode is set to Access Point. Is that right??
    - Wireless Network Mode is G-only
    - I changed the default SSID name
    - Wireless channel is set to 11
    - SSID broadcast is disabled
    - Security Mode is WPA2 Personal
    - WPA algorithm is TPIK+AES
    - shared key is a bunch of random characters i made up
    - Wireless MAC filter is enabled
    - advanced settings are all default EXCEPT transmit power is 67% and beacon interval is set to 50

    I had hoped that the new firmware plus the nvram clear and hard resets would help but they have not. I have noticed that connections sometimes drop when we're using the phone, but sometimes they drop for no reason - like maybe I'm getting interference from a neighbor. If there are advanced settings I can fine tune to fix this problem, I'm all for that. Also, please comment on my security settings. I want good security, but not at the expense of poor connectivity.

    Would simply turning up the output power help? I guess it might help with the transmit, side, but it won't help with the receive side, will it? And will running with the transmitter cranked way up cause excessive heat or other issues with the router? Of course, it may have some indirect benefit, by encouraging my neighbors to ditch their wireless routers. Just kidding. I'd rather not cause them undue problems if I can avoid it.

    Would playing with the transmit and receive side of the antennas help? My kids' computer is down and to the right of the router. How about the direction I point the antennas? Should I point them at the ground?

    What if I cranked up the output power, then added some sort of custom "receive" antenna on the router that could catch my remote computers' signals better?

    Any other suggestions, besides running a CAT5 cable from the router to the onboard ethernet port on the PC? :cry: 8O

    1. Do a "Survey" from Status->Wireless. Pick channel that is 5 channels distant from other strongest signals, use that.

    2. Disable your 2.4 GHz phones, substitute 900 MHz or 5 GHz phones.

    3. Get better antenna. Good antenna increase BOTH ability to hear distant/weak clients and they improve transmit gain as well. Increasing transmit power is like shouting across the room at a party ,doesn't do anything to help you hear the person whispering back. Improving your antenna could be a simple as making a reflector like the ones at http://www.freeantennas.com/

    Vincent, thanks for your fast reply. Dumb question: does the antenna go on my router or on the PCI adapter on the PC?

    What commercial antenna(s) do you recommend?
