Guys, I have a C1200 v1.0 with TIME connection. Every once in a while (sometimes once a few days, sometimes once a few hours), the router would seem to be unresponsive, WiFi and LAN will show to have no internet connection, and neither the wired PC or WiFi connected phone can access the router interface. It will only recover when the router is powered off and on. I have searched from Google, and some have suggested to disable 5Ghz WiFi, and some have suggested to disable ipv6. I have done both but it seems like these solutions are temporary, the issue will come back after a few days/weeks. The firmware is 1.0.0 Build 20180502 rel.45702 (EU).

Does anyone of you have this experience before? Any solution?

Thank you.
