WRT45G V2 - Wireless loosing connection upon heavy file transfers.

    I started a series of downloads today, not using many connections but all of my 10mbit/s bandwidth.

    My wireless connection is dropping very often, about every 10-30 minutes and reconnecting directly. Checking the firmware (using Tomato 1.6) it seems as the whole router is rebooting every now and then.

    Could this be due to overheating? My ambient temperature is about 22 degrees celsius, and the router has space around it.

    I've been using it for a while and I haven't had any problems before, but this is the first time I've used this much bandwidth over such a long time (now it rebooted agains as i wrote this).

    For those of us not in tune with the measurements of the rest of the world, thats roughly 72. Could it be heat? Well yes but at that temp unless you have the device overclocked or the output power pumped way up i dont think that is the case. As to what else could be causing it i am not sure, its really sounds hardware based but to be sure, reset the router to factory to flush out any potential issues and then test. Its problem is still present you could try another firmware and see if the problem is still there. Once determine either way where it lies then you will be much better prepared to move down the road to resolve.

    I just let it idle for some while now and it hasn't rebootet yet, so it is due to heavy traffic.

    I'll see if I can dig up another CAT5 cable and see if it is exclusive for the WLAN and not also for the LAN.

    I'll keep you guys posted on my progress..

    I reverted to the original firmware. The problem is still there.

    The router does not reboot when idle, only when having around 1MB/s throughput for a while.

    could be a long shot but try a new wallwart (power supply) to see if it helps any

    Not so much a long shot as when the router in under load it should draw more current, though i dont considef 1Mb heavy load.

    10Mbit/s is the speed available here, so 1MB/s is about maximum I can get, though the router should be able to handle more.

    Do these routers have any history of overheating, even when not overclocking or such? I got a tip that tomato by default boosts the transmission and that consumes more power, but the problem is still there using the original firmware.

    Where in the original firmware can one find the uptime of the router?

    Tried connecting using a cable instead of wireless and so far so good. How can the wireless make the router reboot, or did I interpret something wrong in the tomato firmware?

    (Seems like I'm just replying to myself :) )

    I think I'm onto something. Could it be a heat issue?

    I tried DD-WRT instead of tomato, I like tomato better but DD-WRT has the option of under/overclocking. DD-WRT overclocks to 216MHz by default and it made the reboots happen even more often. Now I am running underclocked to 192MHz and it seems stable. Have had 10mbit throughput over my WLAN for the last 1-2 hours and no reboots so far!

    Should it overheat when running at stock speed? It sure seems that way.
