My rt-n16 seems to be rebooting at random points. Sometimes every 3 or 4 days, or sometimes a couple times a day. I first noticed it when the uptime status was not increasing beyond a few days. Then my chumby started to come up with the "select network connection" screen sometimes.

I enabled logging remotely to my server to retain the logs between reboots, but don't really see anything in particular that looks bad. Here's the log file that's been captured since 6/26:

I tried to just edit out my MAC addresses and WAN IP…

I had the same problem. I ended up sending it in for a new one. I think there is an overheating issue.

After searching some more here, I found and installed the 9055 build. Up 1 day so far, hopefully it continues!

I've got the same issue with the latest toastman builds on my RT-N16. I don't exactly know at which build it started as the issue does not happen straight away - uptime can be anything between a few hours and a 2-3 days. Logs do not show anything at all. I'll try connecting a serial console and see if I can get a kernel crash log this way.

Heavy P2P traffic seem to trigger the bug as far as I can tell - I've got 2 RT-N16s, one at home serving 10+ people downloading all day, and one at work serving around 25 computers doing only web browsing/email/other work-related stuff. Same build, the configurations are a bit different of course, but the work router is rock solid, while the home router randomly crashes every now and then.

docdocdoc9 - Can you post which versions you found stable and which ones are rebooting? Thanks.

Toastman, I'll try to get a serial dump next time it happens. I'd love to try older versions but as crashes only happen every few days this could be a very, very lengthy process :)

FWIW, I use an Asus RT-N16 with "Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB Ext" and do not experience any sporadic reboots. My RT-N16 is stock (no fan modifications, no overheating issues). I'm talking 2-3 months of uptime (and only that short due to the fact that I tend to disconnect power when working on unrelated equipment).

By the way, how would you go about getting a serial console dump on the RT-N16 without modding it? Are you sure something didn't get damaged in the process of using something like this (assuming this is what you're using) http://infodepot.wikia.com/wiki/USB_to_Serial_TTL_Mod#Asus_RT-N16 ? Wired it up wrong briefly which may have sent voltage to the wrong pins, etc…?

One more thing: OpenWRT's site claims these things don't even have serial ports, so you'd have to do some sort of mod or have an in-line AD233BK doing the work, which means a PCB with voltage running across it that could be pressed up against something (shorting something out), grounded improperly, etc… http://wiki.openwrt.org/inbox/asusrt-n16#serial

Just saying it's something to consider.

A different page on OpenWRT's site (a "WIP" version) indicates there's a serial header, but you still need something like an AD233BK to do the conversion. http://wiki.openwrt.org/inbox/asusrt-n16/wip

RT-N16 has pcb tracking for both serial header and JTAG header. The serial header needs level shifting via the usual methods to interface with a PC. Easiest way is to use an easily obtainable mobile phone interface cable - plenty of information on the web about this.
