    I would like everyone to post here the longest radio links which are made with Tomato and the speed results.
    I made the ~8.5km link with no full line of side with 2 Buffalo HPs, 24dBi grid antennas and Tomato 1.09.
    The signal is ~-54dBm, noise ~-80dBm. The download speed(LAN to LAN, TCP, windows file copy, the source speed is ~1.5MBYTES/s) is 6.5Mbites/s, ping is 1ms.

    ACK=7800, Mode: WDS with WPA-AES, 50mW Xmit power.

    The world record was just broken for wireless link distance with off the shelf routers, i believe it was linksys wrt series. If i remember right it was 137miles (apprx 220km).

    No. I didn't mean the world record. I mean a real life high speed and working links with Tomato only.
    For example 20km ~2Mbites/s or something like that. What settings, what problems and etc. :)

    Does the wall counts ?;) With default antennas I've got a 3-concrete-wall conection at -80 db with an Asus WL-138G WiFi card.

    I have 2 buffalo HP at 7 Km with 24 dB grids. With Tomato 1.07 I have 1 radio set for 10 mW and one set for 18 mW. Both radios have the RX pre-amp enabled. The 10 mW radio has -40 dB from the 18 mW radio and the 18 mW radio receives -44 dB from the 10 mW radio. Noise level is -99. ACK seems to center best at 6600 but has a nice wide margin. Bandwidth is everything the 7 Mbps the cable can give me. I've never loop tested, but pings are a string of 1 ms. I am locked at 36 Mbps air rate and with frame bursting enabled so I should have at least 16 Mbps bandwidth available. Mode = WDS only, no encryption.
