Synology released two router updates recently. The first was back on December 19th which was re-packed and re-released on December 26th to fix a bug introduced in the update. The second was released December 26th and included a few updates in addition to fixing the bug they introduced on December 19th.

The December 19th update, SRM Version 1.1.6-6931 broke the LAN 1 port on the RT2600ac router. All I lost was time since it is the only port I use (to connect to a switch) and I could just move to another one. I can also report that the December 26th update does fix the problem and I’m now back on LAN 1. While I would not have expected a firmware update to break just one LAN port checking ports is early in the troubleshooting process and easy to do. In retrospect, it’s less surprising since the port can do double duty as a second WAN port.

SRM version 1.1.6-6931

Released December 19th (re-packed December 26th) and contains the following changes and fixes.

Just under two weeks ago Synology released a DSM update that had to be pulled back to be fixed, and they needed a follow-up update to fix what it broke. Now an SRM update breaks a LAN port. While relatively minor, it required troubleshooting and the back-to-back problems are a concern.
