Tomato 1.28 by shibby flaking out - refuses to serve DNS

    This is a peculiar problem. I've been running Shibby on my network for 6+ months without any issues except the occasional reboot was required. But for the past week we have begun observing a peculiar problem that is getting worse by the day.

    After a bit of uptime, the router stops providing DNS to the machines on the network. I have my DNS set to, & When this happens, you can go into network settings on windows and manually add DNS to your connection and everything will continue to work perfectly but if you set it to get DNS automatically it will not work. This problem has popped up out of nowhere. It used to happen once a month or so before but a reboot of the router fixed it. But now, it is happening several times a day to the point that DNS only works for a couple minutes after reboot and then breaks down again.

    Manually setting DNS is not an option for devices such as Roku & Xbox even if I can do that on the PCs. Any advice would be much appreciated.

    I use OpenDNS and have never experienced such an issue. Their DNS servers are found at and perhaps you can give them a try...

    I would suggest you stop using and, for starters. These resolvers are Verizon/GTEI-provided "to the Internet as a nicety", and are highly susceptible to whatever practises Verizon puts in place on their network, ditto with some other providers that peer with them. Basically, and are supposed to be used by people as a temporary DNS server for testing purposes, and not as permanent public recursive resolvers. Verizon/GTEI has been very clear about this. People using their resolvers indefinitely is considered rude and potential for blockage or rate-limiting.

    I would suggest trying OpenDNS or Google's public recursive resolver ( and see if the issue persists. Although, if I was in person giving you advice verbally? I'd be asking "Why aren't you using your ISP's DNS servers?" (it's a legit question).

    I was using until 2 days ago when it went down (for me at least). I thought that was the cause of all my woes so I replaced Google with Verizon.

    I am in Costa Rica. My ISP's DNS servers are unreliable, have really long refresh times and generally are a clusterf***. The only people I imagine who would use them would be the people who don't know how to change the ISP's default DNS servers after the cable guy sets them up.

    I should reiterate that I have already done all necessary research and I can confirm that what DNS servers I am using is not related to this issue since I put the same DNS servers that are on the router directly in my windows network settings and they work fine. It is something the router is flaking out on.
