    Long time user of Tomato, I recently upgraded to the latest version 115 of AdvancedTomato (tomato-K26USB-1.28.AT-RT-MIPSR2-1.15.14-Big-VPN.trx) from 114 Shibby (non AT). Since the upgrade, I experienced random reboots occurring mainly 1 time per day (but I did have a day with 4 or 5 reboots).

    First thing done, I did a full NVRAM reset and reconfigured all settings manually (full config at bottom of post). Nothing change, still getting random reboots almost every 24 hours + ~1-4 hours.

    As It was not working, I switched to the standard Shibby version (tomato-K26USB-1.28.RT-MIPSR2-115-Big-VPN.trx). I did a full NVRAM reset again and reconfigured all. Same thing.

    As this was getting weird, I enabled logging on an USB flash drive but I did not get any useful log. The log just stop when the router reboots and after that, I get only the standard boot log...

    Finally, I switched to Toastman (tomato-K26USB-1.28.7503.5MIPSR2Toastman-RT-Std), NVRAM reset, redid all my settings. No reboot since.

    FULL CONFIG (if nothing is indicated for a particular setting, assume default) :

    I had this same issue with AdvancedTomato and using a Linksys E4200v1. It would constantly drop all internet connections every few hours causing me to reboot the router.

    I loved the GUI, but it was too unstable for my liking, so I went back to BB-WRT

    Unfortunately, I don't have time for testing. It's my home router and I can't just take it down. My current installed firmware works fine and has all the features I need at the moment.

    My initial post was more a warning/informative post to members in case it was not something weird in my setup.

    I believe we don't have the same issue at all. My router rebooted by itself and the connection came back naturally after 1 or 2 mins (boot time).
