TomatoUSB

Until two weeks ago, my RT-N16 had the basic build 54 of TomatoUSB K26 MIPSR2 from tomatousb.org, and had run flawlessly for months. I never had any downtime with this thing. The week of Thanksgiving, it locked up, and just the power light was on - both wifi and ethernet connections died. Since then, it has died almost every day. Nothing changed prior to the crashing, it had run so flawlessly for months without downtime that I never had any reason to change even a QoS setting.

I've tried multiple nvram resets, upgrading to Tomato RAF (which I had read was the most stable updated release available), and finally doing multiple nvram resets while using ASUS recovery tool to upload Toastman's newest build, followed by more nvram resets and even a 30-30-30 attempt, but no luck, it is still crashing.

Anyone had a similar experience and found a fix? Are there any troubleshooting tips I can try, perhaps checking logs for info, or does it sound like I have a dead router? It's frustrating, because with the new toastman, I've doubled my speeds and the wireless, and I'd prefer to find a fix instead of having to spend $150 (I'd upgrade to the RT-N66u).

I've also posted this on linksysinfo.org, sorry to spam, just really hoping I can get it figured out! Thanks for your help!

Not sure what version of Toastman you're running, but I had a similar issue awhile back with my N16. I believe I performed a 30-30-30, put the router into recovery mode, then uploaded Toastman 7499 VPN. Manually typed in all of my settings (didn't try to restore). Once I had it running solid for a week I put on 7500.4 VPN-VLAN and it currently has an uptime of ~39days.

Perhaps doing factory reset will change something? What do you see in your dmesg logs, btw?

I've done factory reset many time and always manually enter the settings again, the only thing I haven't tried is going back to ASUS firmware. I have tried a couple different brands of Tomato, none of them experimental builds either.

For now, I've contacted ASUS support in the hopes of an RMA, and have moved the router to get some better airflow while lowering the CPU freq from 480 to 453. Hopefully that will keep its table for a little longer.

Also forgot to mention that the logs don't save between crashes, I might be able to set it up to save externally, but I really think it dies instantly and the logs aren't going to be able to record an error fast enough, if at all.
