WRT54G connection trouble

Discussion in 'Cisco/Linksys Wireless Routers' started by Davido, Jul 1, 2005.

    I have a WRT54G v2.2 flashed to HyperWRT 2.1b1. Ever since I began using this router, all the clients connected wirelessly to my wrt have had their connections drop every so often or even hours at a time. When I flashed to HyperWRT, the drops have become less frequent but are still a problem. I got this highly regarded router to replace my previous Microshitty MN-500 but the way things are going I am tempted to switch back.

    I really don't know what to do now. Should I try to flash it to the 4.00.7 firmware?

    The clients connect to the router wirelessly with the Microsoft wireless USB adapters(MN-510, I know I know)

    To me it sounds like a signal issue. You need to see what your signal qualiy looks like. Also, If you use programs such as bittorrent then that will cause issues.

    WLAN quality denends on weather and solar activity (believe it or not)
    also, humidity and moisture absorbes in the 2.4GHz spectrum, which is WLAN 802.11b/g.

    the effect you seem to have is your WLAN client (PC) trying to MAX up the bandwidth of your link.
    either reduce the basic transmission rate of your WRTxxx whatever, or reduce it on your PC.
    I have a signal reception of -17dBm, or something like 66-70%, and a 6Mbps link in 802.11g which is rock solid.
    54mbps however is a no-go, obviously.

    so throttle that down, or throttle your TX power of the wrtxx up ;)

    if all that doesnt help, adjust the antennas of the WRTxxx or buy seperate, directional antennas.
    depending on how much you want to spend, you can grab several dBs EIRP ;)

    I had my wireless network mode at Mixed because my brother has a laptop with a 802.11g card. I changed it to B-Only and changed the Transmission rate from Auto to 6Mbps. I hope this fixes my problem. In case it doesn't, ho w do I adjust my TX power and what should I adjust it to? Is it the same as "Transmit Power"? If so, it's at 42 mW due to the HyperWRT.

    yes, thats the Transmit Power.
    42mW is above standard already.
    imho 128mW is the max you can get.

    Try to get hold of a reception signal indicator on your windows PCs / laptops, and then fiddle with the WRT54G antennas.

    also, you might consider buying a bigger directional antenna. they're cheap. shouldnt be more than a few bucks.

    Okay, I'll use netstumbler and fiddle around with the antennas. I was actually considering buying the HGA7T for my WRT.

    I've fiddled around with the antennas and simply can't get a good position for them. Any position I put the antennas my client computer still gets disconnected. I've also raised my TX power to 67%. I am really disappointed with the performance of the WRT but I haven't given up hope. I will try to build the Ez-10 10 dBi Corner Reflector as a last resort. If I use the reflector, will the signal to the computers in the opposite direction worsen? I was also thinking about building the Ez-12 Parabolic Reflector. Will that also worsen the signal to the computer opposite in direction of the Windsurfer?

    Can no one help? I've tried switching to the official Linksys firmware v.4.00.7 and it's done nothing, it may have even worsened the situation. Any ideas? :cry: I need to get the family off my back.

    the antennas in those USB adapters are smaller than ant penisses....

    Have you tried a built in PCI card for the desktop type PCs?
  12. Davido

    Davido Network Guru Member

    I know, it's a pretty crappy usb adapter but it works. I haven't tried a pci adapter but I know it must be the router as my client computers pick up other signals just fine. The laptop computer with built-in wireless gets disconnects as well.
