Sourrounded by 13 other AP's, what to do?

    Hi there guys,

    I'm using a WRT54GL with Tomato 1.07 and a WMP54G with RaLink-drivers to connect my PC to my 6 meter away router which hangs at a cable-con.

    What I'm experiencing here, are huge lags which I hadn't earlier when gaming BF2 and bandwidth issues.
    That started around one month ago. After experiencing with another Linksys router (WRT350N) and changing the drivers of my WMP54G from the original Linksys ones to the native RaLink I at least discovered the reason for those lags. Well, I hope i did...
    Thirteen other AP's, trying to reach their masters...
    And by using those drivers, the lags reduced from around one per minute to one every four minutes (estimated).
    I discovered a "Noise strength" of 79 dBm measured by RaLinks tool. "Link quality" is at 100 % and "signal strength" around 50 dBm. Am I right that those numbers aren't good?

    Here are some results: sorry for the germish
    Code:
    Ping-Statistik für 81.3.59.4:
        Pakete: sent = 50, received = 50, lost = 0 (0% loss),
    Ca. Zeitangaben in Millisek.:
        Minimum = 24ms, Maximum = 3628ms, average = 108ms
    Code:
    Ping-Statistik für 81.3.59.4:
        Pakete: sent = 50, received = 50, lost = 0 (0% loss)
    Ca. Zeitangaben in Millisek.:
        Minimum = 23ms, Maximum = 872ms, average = 49ms
    Those stats are done in a row thru the cmd-prompt of XP SP2.

    And now some with the implemented ping-tool of Tomato:

    Code:
    Round-Trip: 22.2 min, 25.9 avg, 42.4 max (ms)
       Packets: 50 transmitted, 50 received, 0% lost
    Code:
    Round-Trip: 22.4 min, 26.0 avg, 38.9 max (ms)
       Packets: 50 transmitted, 50 received, 0% lost
    I tested also the difference between connecting directly to the cable modem thru TP with my gf's lappy: rockstable, 16 MBit. When using any of both routers, connected thru TP: rockstable, 16 MBit. Same laptop, 10 seconds later by W-LAN, 50 cm distance: 2-4 MBit. :help:

    So, does anyone has a suggestion what to do to get a stable WLAN again as I used to? Preferably without any crazy transmit power settings. That could just lead to problems with officials here so I would preferably avoid that option.

    Thanks for your thoughts.

    I just played around with the channels here. Now using channel 2, which dropped the signal strength to 63 dBm but the Noise improved from 79 dBm to 95 dBm. Seems to work for the moment but isn't a solution as I expect more AP's to be added in the neighbourhood.

    Could it be of any use to buy a Draft-N/MiMo Adaptor or even another Antenna with a higher gain? How much should that be, 10 dBi?

    Ok, I'm still getting disconnected.
