WRT54GL v1.1 with Thibor 15c Restarts and Unstable Wireless

    Hello,

    I’ve got a WRT54GL v1.1 with Thibor 15c on it. I’ve only been using it for a few weeks. I really like it, except for the two issues I’ve been having that may or may not be related.

    1. Wireless connectivity is unstable. My wireless card has to reconnect at random intervals. Sometimes it’ll be stable for several hours, other times it will reconnect every 20 or 30 minutes. It says the signal strength is excellent and it’s sitting 3 feet away from the router. There are also 2 other wireless cards about 30 feet away which also experience the random signal dropping. They do not all disconnect at the same time though. Wired clients rarely loose their connections. I’ve tried running on channels 1 and 3 (6 and 11 are what other people are using according to the routers “Site Surveyâ€. The wireless cards worked well with the D-Link DI-524 I had.
    2. The router itself reboots every 1 to 4 days. The web GUI is very slow to respond under heavy BitTorrent traffic (maybe that’s normal?). There seems to be no pattern to the reboots…often they are when there is little or no traffic.

    Settings I’ve changed:
    --Changed password and time zone
    --Moved to the 10.x.x.x. internal IP block
    --Added static DHCP entries
    --Enabled WPA on wireless (running on G-only)
    --Redirected 4 ports
    --Enabled QoS
    --Enabled SSH

    The strange part is that I had another WRT54GL v1.1 that was doing nearly the same as this one is (actually it was rebooting more often). After trying to figure it out, I figured it was a hardware problem so I RMA’d it and Newegg sent me the current router. Since this router is doing the same thing, I’m not so sure it’s a hardware problem now and wouldn’t be surprise if I’m doing something dumb.

    Do you guys have any suggestions that would help me figure out the cause of all this?

    Unless you've updated from stock firmware to Thibor so OK, otherwise reset the unit and clear NVRAM too before starting new setup in Thibor.
    On "Site Survey" takes a notice on RSSI higher is better, than you can consider which channel your wireless signal is best suited for you (changing around)

    If you pay close attention, we're talking majorly about disconnections. :frown:

    My RSSI numbers are all negative. They range from -43 dBm to -72 dBm. When you say "...on RSSI higher is better", are you talking the absolute value or not? (i.e. is the -43 or -72 better?)

    You're right talking about the absolute value! Your channel can be on the same channel w/o interference if RSSI has a good value.

    lol, dude, he's not talking about that.

    does it disconnect only when u run p2p?

    Your post isn't much to help!
    - Instability could lead to WRT54G restarts so often
    - Disconnection could be the channel isn't selected right
    Using my WRT54G as WDS for months so the hyperwrt firmware itself is very stable, the rest is how the setup could lead to the bad result

    But that's the thing, he's asking what value is better, a higher negative or a lower negative.

    Not how the channels need to overlap and RSSI this or RSSI that, lol.

    It happens when I'm not running P2P also. I've actually only done maybe 5 hours of P2P traffic on it, and it didn't restart or drop a connection once during that. It's restarted and/or dropped connections under general web browsing and sometimes in the middle of the night when it's idle. So, no, it doesn't look like there's a usage pattern that causes these problems.

    I tried using an older router for the past 5 days and had the Linksys in the corner of the room, with no WAN or cabled LAN and just a single wireless connection to it. I reflashed with Thibor 15c before putting it there (and restarted and cleared NVRAM) and changed only the wireless encryption and password. It seems a bit more stable, but restarted itself once at about the 4 day mark and dropped wireless every so often.

    Is there a way to save the system logs on the router or somehow get the router to tell me why it reboots? The logs unfortunately get purged on each roboot.

    I have a WRT54GL v1.1 as well, bought it after I bricked my WRT54G v2.2. I have experienced the wireless disconnects you are facing too, and still had problems when I switched to Tomato firmware.

    I'm still using Tomato, but have since removed WPA encryption and merely use wireless filter. Perhaps there is some problem with WRT54GL and WPA, I cannot sau for sure.

    Thanks for the reply. I've got a couple quick questions:
    1) Did your wireless become more stable when you stopped using encryption?
    2) Does your router restart itself every so often? What's your uptime on the status tab? My router restarts itself after about 4 days, give or take about a day.

    I think it's been a few days since I had a drop in the wireless connection, and that possibly due to me being out of range of the router.

    Sorry, can't answer your second question though. I recently set up my router to reboot early every morning.

    I get disconnects too, and I have no clue why.

    Now, I even disabled Wireless security, and I get disconnected very randomly after 5-6 hours or so.

    My roomies' laptops get disconnected as well.
    I'm using XP pro D-link DUA-1340 with the GUI provided by D-link, new drivers as well.

    Seriously now, how can I have a stable, constant connection to my router running 15c?

    I'm using Windows XP Pro SP2. The wireless adapter is a USB one from Zonet. Specs are at http://zonetusa.com/DispProduct.asp?ProductID=139

    Since the router has been sitting in the corner of my room not being used (but plugged in), the router itself and wireless has been a bit more stable, but I'm still getting random disconnects.
