best firmware for mesh network

    Any recommendations on which firmware is best for configuring a 20 acre mesh setup? I need to get coverage for a 20 acre senior citizen mobile home park and would like to deploy several (as needed) WRT54GL units in a mesh. They all would talk back to one business class broad band link.

    Any recommendations?

    i think that would stirr up an argument.. i think any firmware supporting WDS would work fine: Hyperwrt, dd-wrt, sveasoft and more

    Why use wds? That will seriously limit your wireless bandwidth with so many WRTS. I would reccomend running an ethernet cable to all of them and giving them all the same SSID just on different channels. Then disable DHCP on all of them and have a central server or router assigning it across them all. This would allow the clients to roam throughout the area with full bandwidth.

    i was assuming that running wires was not an option, but yes that would be better, he didnt say either way though

    WDS is not really suitable for a mesh network. You should use the ad-hoc mode with OpenWrt and something like OLSR.

    running wires is an option

    I like the suggestion of same SSID and running wires does seem to be an option at this senior citizen park. But I have some followup questions and really appreciate any assistance.

    (1) if I boost the signal (power) on a WRT54GL what kind of coverage will that give me? assume I am covering approx 20 acres in a rough square configuration - for example 400 yards by 400 yards. How many boosted WRT54GL's would it take to get decent coverage?

    (2) if I have to place these units beyond the recommended run length of cat5e type setup (90-100m) do I just put powered switches at intermediate points to get further distances? I have seen references to "industrial ethernet" - any idea what that is and how far you can run that before it exceeds the recommended length?

    (3) lastly would you recommend I use PoE (power over ethernet) or just try to get these units pole mounted near a regular power source...

    Forget the transmit power tweaking. Use decent antennas....
