WRT54GS and Intel 2200BG - not enough channels ?

    I have a WRT54GS-UK v1.0 and am using it with a PC that has a WMP54GS v1.0 card and a laptop that has an integrated Intel 2200BG based chip/card. Prior to this point, the WRT had been running the 3.76 version of the Linksys firmware.

    Up until recently, all was running well, and then I started to have network dropouts on the PC with the WMP card, which was most irritating, as it is my media server.

    On checking, I noticed that reported speed of the WMP had decreased significantly, and I have had cases very recently, where both the laptop and the PC go off the air completely and cannot even see the wireless network.

    I upgraded drivers, installed new (standard) firmware on the router, changed all the channels, tried all the combinations of settings on/off, all to no avail, the problem persisted. I strongly started to suspect that some of my neighbours must have bought wireless kit, or were using DECT phones, which in the UK operate in the same 2.4GHz band as the router and that one of these things or more were responsible for my current problems.

    Someone then mentioned this site, so I came here and did some reading and was greatly interested in all the new firmwares available, particularly in ones that might allow me to boost signal strength or adjust roaming "stickiness". Being a cautious fellow, I did not want to stray too far away from the "official" firmware however, so I tried the latest 2.1b1 revision of the HyperWRT firmware. I turned the signal strength up to max, and there was an immediate improvement in performance.

    Success, but it's still not as quick as it used to be. I then noticed that the HyperWRT firmware had added two additional channels (12 & 13) that I did not have previously and so I bumped the channel to 13. Again, success !!

    The WMP is now perfectly happy talking to the router and is at full speed again, seemingly confirming that the channels and frequencies from channel 11 downwards, were being swamped by outside interference. However, the Intel card goes off the air completely and will not come back on again until I change the channel to 11 or below, at which point it connects again at full speed, but the rest of my network degrades again.

    In short, is there any way of getting the Intel card to operate at the frequencies and channels above channel 11, because that would put the final piece into the jigsaw for me and make me a very happy man ?

    Depending on where you live, it can be illegal to operate on channels above 11.

    I live in Northern Ireland.
    Anyone have any idea whether it is illegal in the UK to use channels above 11 ?

    if you live in northern ireland its ok to use channel 13.

    the channels you can use are:

    Channels 802.11b / 802.11g

    1-11 Channels (US, Canada)
    1-13 Channels (Europe)
    1-14 Channels (Japan)

    So no Problem for you. I got the same Problem with my Centrino Notebook, with the 2200 BG i cant see my WLAN with channel 13. Try to get a europe driver for the 2200bg chipset.

    Thank you very much for your response. The laptop in question with the 2200BG in it, is a Fujitsu-Siemens S6120 and as you rightly surmise, is currently running the US driver. I have managed to locate an earlier, European version of the driver (v9.1.0.9) and will be trying that later. I will post back with the results.

    Thanks again for your help. Most useful.
