WRT54G in WDS Mode....how much boost & other questions..

    Here is my configuration...

    [​IMG]

    the WRT54Gs 2 and 3 are configured for WDS, they both show WDS as functioning under the wireless status page but report a big fat 0 for signal strength. When I move them in the same room, the signal strenth increases but they still arent speaking to each other.

    I can get the 3rd WRT54G to connect to my laptop but its not passing though any DHCP or whatnot from the LAN. From every guide I have read I have WDS set up properly as well.

    Now regarding signal here is the kicker. with a regular PCI linksys card in computer 1 it not ONLY picks up signal from WRT54G #2 (with a decent signal) and #3, obviously but gets a very faint signal from #1. I can connect the computer 1 or 2 to AP #2 (which is hooked up to LAN) but it only gets an IP like half the time and when it does it works for like 1-2 minutes before it drops out.

    So questions.

    1) Since the computers can connect to AP #2, should I just scrap the whole WDS and #3 router idea?

    2) Why the hell is the signal dropping out. Netstumber reports about a -60 db signal from AP #2...

    3) What should the transmit rate be set to? Default is 28mW but with this firmware I can crank it to 251mW. Changing the signal on AP #2 doesnt seem to change the signal much although when I crank it real high it stops getting an IP all together and even higher the computers stop seeing AP #2 all together.

    4) Do you think my problems are related to this specific firmware? Perhaps I should go back and try the regular firmware again? Or OpenWRT / DD-WRT ?? I am running Sveasoft Alchemy 1.0

    As far as WDS not communicating, try removing all encryption. See if you can get a plain-jane vanilla WDS connection. For some odd reason, my WDS setup using three 54Gs will not talk with encryption enabled (I'm researching this now)

    Also, as far as DHCP goes, one workaround I needed to do for mine was to enable "Use DNSMasq for DHCP" in the primary router. If I set a static IP, everything would work fine. Set for DHCP and it would never pull an address.

    Both are problems I've run into and hopefully they'll provide some insight on where you can focus your troubleshooting at.

    Good luck!

    Alright, I will try disabling WPA and using DNS Masq when I go in tomorrow.

    From 84 to 126 is an appropriate signal strength. You may use up to 168 without any problems, given an average room temperature and no nonstop accesses.

    By all means, collect all of the devices into the same room until you get WDS working. Relocate them after you have WDS working.

    Thibor's HyperWRT and DD-WRT V23 Basic Generic can both work wonders on WDS with WPA encryption. I can't remember which one prefers TKIP and which one prefers AES. I think that Thibor's demands that you set the Wan port on Disable (for those devices that do not connect directly to the Internet). Maybe both of these require that setting for WDS use.
