NOTE: reboot is not always happening at the same time. 
to reproduce: it's better to test few times.

most likely bug resides inside open source driver for broadcom ethernet

This may not be a software problem. These routers are known to have issues with 
bad capacitors in the power supply wall wart and the router itself. For 
example, see: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=56939

My WL-500W used to be perfectly stable when copying multiple gigabytes from a 
fast file server on wired Ethernet to wireless or from Samba on the router 
itself to wireless. Recently, the router was stable enough for web browsing, 
but even downloading software from the net was enough to cause a reboot. I 
thought I was running into this bug, but then I downgraded to r2624 which was 
stable before and it was also unstable. After opening the router I saw an 
obviously bad capacitor right by the toroidal inductor near the power input. 
(To open, remove the rubber feet, unscrew the 4 screws hidden by rubber feet, 
and remove the top.)

No, it's not related to hardware at all.

I have r3323 right now. It's pretty stable, no reboots at all under heavy load, 
the only problem is internet disconnects sometimes if there is a heavy load, 
like there is no enough network bandwidth to keep connection alive.

Hm, interesting, after replacing capacitors inside the router has it fixed the 
bug?
I don't think in my case it's capacitors - when AC dead router obviously wasn't 
working at all, so I replaced capacitors in the AC.

If I do copy a lot over Samba / LAN-WIFI this issue is not happening, so most 
likely it's not a hardware issue. It only happens if you do massive download 
from the WAN.

P.S. I'm gonna try r2624 and report back shortly..

The AC adapter was bad too: it couldn't maintain a reasonable voltage under 
load, and the 1200µF 10V output filtering cap was bulging. After replacing 
that and the 1000µF 6.3V cap in the router that filters 3.3V power, my WL-500W 
appears stable. 

I'm just using as it as a switch, wireless AP and occasionally internal router, 
and not as my Internet gateway. If you only have instability during heavy 
Internet connection load, that seems more like a software issue.

Well, in my case it's definitely not AC adapter or internal capacitors inside 
router, it's firmware itself bugging.

I never had such issues on 2.4.20 Oleg's original firmware - it was stable as 
f**k.

I have to use this new -rtn firmware due 802.11n card BCM43222 inside my router.

No useful info in issue

I don't care anymore, because I got rid of my WL-500gP v1, so you can close 
this issue if you want.
