WRT54G-GS Interfere with each other?

    I have 1 G and 1 GS back to back and I am encountering speed problems with the GS......

    I am using the G router as a B-Only AP for my wireless media center and the GS router is set for G-Only for the rest of my network.

    Before I set my wireless media center I had both routers running the same configuration and never had a problem with network speed droping below 48Mbps. Since I have set the G router to B-Only my GS drops off to 1Mbps with the G router staying at a steady 11Mbps.

    I had the dd-wrt v23 final in both and thought that was causing the speed.

    Now I have Hyperwrt in both and still experincing the same problem.

    I have gone through multipal config settings on the GS router and the remote PC with no luck getting the speed up. After each setting change it would come back at 54Mbps and slowly drop to 1Mbps after about 5 min and stay there.

    Internet--------->GS router--------->G router-------->PC

    Am I overlooking something simple?

    How close are the two routers to each other? Are they using the same channel?

    If they are overlapping each other then I'd definately keep them on seperate channels or they would interfere with each other.

    I had the 2 routers stacked on top of each other at first. Getting down to the root of the problem I have them seperated at 7ft (longest set of cables I have) and still no difference.

    I have the G router on channel 11 and tried every channel on the GS router. Again same thing.

    Yes, that is supposed to happen.

    You need to change your "G only" router to mixed. If it is set on "G only" then it will not correctly recieve "B" signals. Instead, they will be interpreted as a loud electronic screaming sound that it can't understand, and it can't hear over that.

    The actual switch between "B" and "G" with the WRT54 G/GL/GS is the "CTS PROTECTION" switch. Set Enabled to prefer "B" signals. Set Disabled to prefer "G" signals.

    Try channel 3 for one of these and channel 9 for the other.

    Since power comes out of the broad side, not tip, not base of the antenna, perhaps you can set the routers in some way so that their antennas are seperated by 90 degrees from the other router and not paralell to the other router's antennas (one WRT54G points lefty, one WRT54G points righty).

    I have both routers sitting at different levels now and the GS router is now set to mixed. The G router is at channel 3 and the GS router is at channel 9.

    I disabled the CTS Protection and it seems to be holding better at 36Mbps But still droping off to 1 after about 15 to 20 mins now.

    It appears I am close to a solution to this very numbing experience.

    With the help I have received and to what has yet to be said I thank everyone for the info.

    The WUSB54GS adapter sucks..................That is what was causing my slow speeds.

    Went out and got a WMP54G pci adapter and havent had a single issue with speed.
