    I am running toastman tomato on Tomato 1.28.7626 ND Std on a WRT54GL and I can't seem to get a decent wireless signal. I have set up a few tomato routers and was always happy. I configured this one and sent it to my brother. He replaced a old linksys unit and the wireless on the new tomato router bairly works. Lots of dropped packets at best. the other router(in the same place) got a good signal everywhere

    Power is a 80mW.

    I did notice that when my laptop or ipad connects and a I ping from the router I get really long ping times.
    Round-Trip: 1297.641 min, 2509.059 avg, 3992.594 max

    Looking at the laptop in the device list - RSSI is around -67/-68, quality numbers of 23-26. I assume the quality number of 23-26 isnt great but I sometimes see numbers like that on my router and it works fine.

    Not sure what else to try... but I did notice a few things.
    • Sometimes after a restart the quality number is around 90 but then kicks down do 50 or so and then this 23-26 number
    • Not sure if there is any relation but on the bandwidth page I cant get any of the graphs on the bandwidth page to display. it displays the transfer rates but the graphs dont work...
    I scanned for other wireless access points and I found none(as expected as he lives in a rural area). I dont know what is my next move, is there something I should install on laptop or router to test this further?

    The signal strength/quality is fine. Your brother's setup has another issue. Did he erase NVRAM after flashing, and reconfigure the router? I used it on hundreds of WRT54GL's without problems.

    we did erase the nvram... here is where is gets more interesting. I had shipped him a second wrt54gl to use as a dumb access point on the top floor. I set that up and had similar massive packet loss on this unit also... this made me assume the laptop was a fault but we had he same problem on both routers when i used an ipad instead of the laptop.

    the only other weird thing I noticed was here was no graphs on the bandwidth pages. is that something that has to be enabled seperatly?

    no. There's some strange problem that you have, I don't know what it is though. 7626 was downloaded by several thousand people and didn't seem to have any major issues, but I did make some major changes to the builds not long after. So if you have remote access you might try flashing 7633.3 which has many improvements.

    If you do flash remotely, wait for at least 10-20 minutes before assuming a flash has failed, or open a second window to the router and see if it still responds (I have never had a remote flash fail yet).

    Do you get the same symptoms with the laptop closer to the router?
    With ethernet?
    With no modem connected?
    When you ping the modem?

    What changes did you make from the default?
    Did you try testing with no/minimal changes?

    Thanks for all the help.... To answer some questions... The long wireless ping times exist even if I am close to the router. If I plug in the laptop to the router it works great. I looked at the results from ipconfig /all on laptop and the gateway/dns etc that I get from a wireless connection all look same as what I get from the wired connection

    As far as setting that I changed.
    I will try to re-flash 7633.3. I agree with toastman I dont see the build as being the issue. I have used this same build on other units before.

    I really want to blame my brothers laptop but the fact that his ipad responds exactly the same way has me baffled. The core thing that I see as a problem is when I ping either the laptop or the IPAD from the router the round trip times are crazy.

    I can use logmein to get to my brothers computer. My problem with flashing is if I erase the nvram the unit goes back to defaults on a differnt subnet without DHCP and then I need him to manually set his laptop to 192.168.1.* subnet and change a few things on the router so I can remote in. When you remote flash is there a trick so I dont lose the abilty to remote in?

    Thanks again...

    On the WRT54 builds, they usually flash OK and reboot without too many problems from NVRAM. It's worth a try if you don't want to drive there and fiddle with it !

    Just FYI, the two things that always seem to give me trouble is Apple devices, and Intel wireless cards. You have an iPad, if the other laptop is an Intel device, then it just coincidentally might not be the router.

    I flashed 7633.3 andhad no better luck with the wireless. I brought over another linksys router on stock firmware and it connected so I know the laptop's wireless is okay.

    I am starting to think maybe the router itself it is bad. Maybe a bad antenna or something else inside the router being bad. If I wanted to flash it back to original linksys firmware do I need to take any intermediate steps or can I just flash the linksys firmware right from the tomato admin page?

    Thanks for all the help...
