    Linksys WRT54G Ver 7 Resets itself Randomly thus Drops Connections

    Hello All,

    Although I have posted on the forum earlier as well, I would specifically like to ask the problem of “ Linksys WRT54G Ver 7 resetting itself randomly breaking the wireless connections”.

    The supporting information is as follows :

    -- Linksys WRT54G Wireless Router Ver 7, with firmware 7.00.6 upgraded as of March-2007 (available from Chinese website of the manufacturer). Configured on Ethernet Internet Cable Connection (used in local neighborhoods, CAT5 wire running from Cable Provider’s Switch to Ethernet NIC of the customer’s desktop).

    -- There already is a switch (and probably other routers) at Cable Internet Provider’s end and at my home end I have to connect WRT54G Wireless Router with it to use this Internet connection over wireless. That’s why the CAT5 wire from the cable provider is plugged in “Regular Switch LAN Ports (1-4)” of the Wireless router, not in the “WAN” port. This lets me access the LAN shared resources of my neighborhood PCs as well (instead of using NAT and router’s assigning DHCP which gives an internal IP address to my laptop and isolates internal network from the whole neigbourhood LAN).


    My Laptop’s configuration is as follows ;

    -- HP Pavillion Dv1000 Laptop, running Windows XP SP2 (with almost all released updates from Microsoft online update) .

    -- Intel PRO/Wireless BG 2200 Wireless LAN Adapter with Intel latest drivers 9.0.4.33. In the wireless driver configuration “Power Management” and “Transmit Power” sliders are set to maximum, while “Throughout Enhancement (packet bursting)” is enabled. Wireless adapter configured and working with Ubuntu Linux 6.04 as well.

    -- “Wireless Zero Configuration” as of Windows default is used to manage the Wi-Fi settings (not the Intel PROSet Utility which usually comes around with latest drivers download). The “Infrastructure Mode” for wireless LAN is used. The wireless connection in the Windows is set on DHCP mode to obtain the IP address automatically.


    My Wireless Network Configuration (in Linksys Original Firmware Configuration page)

    -- Have made a unique SSID and set to broadcast. The router and wireless card on the laptop both set in “G Only” mode since I do not have any 802.11b devices, so no need for mixed mode.

    -- Using default “Channel 11”. WEP security method with an ”Open Passkey” authenticated when connecting to my wireless network. The MTU is default ‘1500’. Beacon Interval is ‘50’. RTS and Fragmentation threshold set to ‘2307’. Enabled ‘Burst Mode’. Made all these settings as advised by some of the gurus whom I came across searching for ways to optimize the Wireless connection.

    -- There are no other wireless routers / networks in my area neighborhood “for sure”. Router is placed within “2 feet” vicinity of the laptop. (basically both are placed on my room table). No substantial obstruction is present b/w the router and the laptop at all.

    My Problem

    -- The Wireless connection drops out at random intervals while browsing internet or LAN resources. This intermittent disconnection may occurs in 5 minutes or maybe in 2 hours, and causes all ongoing connections to break out and reset. The wireless connection icon in the Windows Taskbar disappears and resets itself to show the Pop-up balloon of the network name and connection strength.

    -- Initially I thought it was something to do with the Intel PRO/Wireless BG 2200 Wireless LAN Adapter, but when it happened quite often, I saw that the “Router Resets itself at random intervals”. All the lights go off and come back after a while. That’s why the wireless connection with my laptop is broken. It may equally be with the WLAN Adapter but I have tried swapping the WLAN adapter too.

    -- Any idea on why is it happening or do other customers of this Linksys WRT54G Ver 7 have the same problem. Any specific firmware available to eliminate this issue, otherwise I am thinking to send it back.

    Please advise and share your information,

    Best Regards,
    S.F.Hasan.,

    I've been having the same problem since I got my WRT54G v6 with Speedbooster. It's apparently a common problem, and a few people say that replacing the firmware with the open-source Linux based DD-WRT fixed it. In my case, it seems to have helped a bit.

    Lately though (this summer), the wireless network drops out randomly, quite a bit more often during heavy network traffic. When it's close to dropping, pings (ping -t router-IP-address) get slow (500+ ms). Also, it drops out more when I set the transmit power higher (a DD-WRT feature; default is 28 mw, can go up to 251 mw). The wired connections are not effected.

    Today the network dropped out and I couldn't even see it from 3 feet away from the router! Today was a bit hot, but not hot enough to run the air conditioning, and the *left* side of the router felt pretty hot. Suspecting that it was overheating, I put a standard 12 volt computer fan about 1 cm from the side of the router, stuck it in place with sticky putty and powered it from a GameCube power brick.

    The router cooled down within about a minute. The network reappeared and is now giving consistently good pings (under 3 ms).

    I suggest you either put a small fan blowing at the router or move the router somewhere there's more air circulation. (Actually, it's better to have it blowing *away* from the router, drawing air past it, but can't really be done here with a standard desk fan.) If you use DD-WRT firmware, set the power as low as you can and still have the network perform at full capacity.
