WRT54GL (v1.1) - Bad signal/connection quality

Discussion in 'Tomato Firmware' started by JoeP, Mar 27, 2009.

    Ok, so I just hooked up a Linksys WRT54GL and immediately installed the Tomato firmware on it. Windows Vista (without SP1).

    I went with this setup because I was having signal quality issues and I was forced to powercycle my router at least a couple times a week. I got it all up and running, hooked up to the internet and all. It was all very easy.

    -------------------------------------------------------------

    My connection after installing this new router and Tomato seems to be worse than my previous standard Wireless-G setup. My Internet connection quality now fluctuates greatly. It is fine one minute then stops to a crawl the next minute and this cycle repeats constantly. Also I should mention that when my connection starts to really crawl, I will jump on my roommates computer (approximately 20-25ft closer to router) to see if that computer is having the same problems but his connection is fine, almost never has hiccups and is constantly smooth.

    That is my site survey if it is any help, I am "linksys".

    That is my device list, I am "Joe-PC".

    And change your wireless channel (look > optimumwifi have this same channel about you and optimumwifi is strongest)
    Set channel 9.

    Thank you. I read that entire thread and all I got out of that was to add this to my Init script:

    nvram set wl0_country=US
    nvram set wl0_country_code=US
    nvram set wl_country=US
    nvram set wl_country_code=US
    nvram set pa0maxpwr=251
    wl country US

    When I did this I was able to notice gains when I increased antenna power but I am fearful or raising this setting because I don't want to burn out my router. Is there a universal safe number to raise this to?


    I changed it to channel 9 and using inSSIDer I noticed my signal fluctuating between 50-60dBm instead of 60-70. While my signal seems to be better now I am not noticing any real changes in Internet connection. Fine one minute, crawling the next and repeat.

    My old Dell Wireless-G router was giving me much better results.

    JoeP - see this post re. Tx Power: http://www.linksysinfo.org/forums/showpost.php?p=340935&postcount=10

    If your existing transmit level is 42mW, then you should be able to get a significant increase from 150mW setting. It may help, but the problem may well be that your PC signal is not strong enough at the router, if so this won't help you. Your clearest channel from the screenshot is channel 11. What is the signal level at your PC using it's own software?

    In fact, you mention 50-60dBm signal, with that sort of strength your connection should be 54Mbps solid. I believe signal levels may not be the source of your problem. The problem you describe sounds more like an incompatible wireless client, what are you using on your PC? Intel? If so, change to Victek release. Read through this thread: http://www.linksysinfo.org/forums/showthread.php?t=60509

    BTW - I'm confused, you posted a site survey, is this from your tomato router? How is it able to list itself in a site survey?

    Thanks for all the posts.

    I don't have time to read the links or make any posts right now but I did want to post this picture from inSSIDer really quick:

    I'm going to assume that is not normal?

    Ralink I believe. I'm in the process of downloading the newest driver from Ralink's website but it'll be a while (5 KB/s).

    I have Everest installed and I've located my wireless card under Devices > PCI Devices but I don't see anything about chipset?

    I had trouble getting the Realtek driver to install so I had to reinstall the bundled software and this is what inSSIDer reads now:

    No matter where I put the wireless adapter the signal is steady as a rock.

    My internet continues to be pretty much terrible. I'm starting to think it might be a signal problem but maybe something else?

    Suggestion - might work, might not. There are 2 ways to connect - the OEM wireless card software, and Windows Zero Configuration utility. Whatever you are using now, try swapping to the other one. On D-Link (Ralink) USB adapters that often makes a big difference.

    Ok, I'm going to mess around with the card software and the Windows software and see if I can get some results.

    Also, I did not do this. Am I screwed?
    Edit: I have internet access but I am unable to access the router CP because of an invalid password. Is there to reset the password?

    Yeah, hold in the reset button on the back of the router for 30 seconds.
