    Recently I installed a WRT54G (Tomato 1.28) as an outside AP in client mode.The distance link is about 100 meters but there are several obstacles in front of the link.
    The best singnal i can get is
    RSSI : from -76 to -81
    SIGNAL QUALITY :from 13 to 20

    Most of the time the RSSI is about -76 and the Signal quality about 15 but sometimes i see the values i mentioned before.

    My question is how many Mbps can pass through this link.I acctualy want the link to pass 13 Mbps of internet.Can i achieve this speed with such a link.

    Thanks a lot
    Friendly Nick.

    I suggest you use a directional antenna such as a panel or parabolic at both ends.

    How many Mbps is extremely difficult to work out and remember WLAN has lots of overhead so the throughput is not even half the link speed negotiated by the router.

    e.g. a wireless G router at full strength can deliver to about 3.5MB/s (28Mbps)

    P.S. I have a similar scenario: distance is about 200m, I use a panel antenna 18dbi and a Buffalo WHR-HP-G54 (built in amplifier) as a wireless client where the AP router is a third party HW with omnidirectional antenna. I also have a bush in between and get between 19-37 signal quality but this varies greatly based on weather condition.

    I did improve the throughput/stability enabling the built in amplifier (not available in other HW AFAIK), disabling "Enhanced RX Sensitivity" and enabling interface mitigation.
