Hi,
For the last two months I've been experiencing constant drops from the internet.
Today I was trying to figure out what's going on and I noticed on syslog that the reboots are every 5 minutes. The router doesn't reboot, but looks like it is rebooting the dnsmasq.
I already tried different builds and doing factory reset several times, with no luck.

Here's my syslog for about 20 minutes, as you can see it is cyclic and happens every 5 minutes.

Does someone know what can it be?

Router: Linksys E4200
Firmware: DD-WRT v3.0-r35034 (but this is happening for about two month with every build)

Doesn't look likes it rebooting, but it is reinitializing the WAN every 5 minutes. And strangely, there's not a single message between the time it restarts and comes back down again. And it's almost 5 mins on the nose every time.

Is it possible your ISP is only providing a short term lease (5 or 10 mins) over the WAN? (Status->WAN)


That's not the case. This is only happening since November/December I think. Now I went back to some August build and everything runs well.
I will try all versions one by one to find which one brought this problem.

Some models are having wireless issues on recent builds. Try e.g. 33006, 33555, 33772, and 34411...though atm the file servers are down.
