I have a WRT1900AC v1 router. I had tried using the firmware with the 4.9 kernel, which gave me the rebooting error, so I downgraded to 4.4 (r4222) and restoring a backup. While the rebooting is solved, there are some warningsin the logs that I can't solve. I am getting a lot of warnings from igmpproxy (see below). I have a static lease for an NAS device at 192.168.1.101. These redirects are happening several times per minute, which may be making the wireless connection worse and causing the router to run hotter than usual.
When searching for answers online to this warning, most results were bug reports with a maintainer saying "try this new version and see if it fixes it", which is not helpful to me...
