I upgraded the RV130 from 18.104.22.168 to 22.214.171.124 and right away noticed that the RV130 would disconnected from ISP for 0.5 second 2-3 times per hour. Turned on logging and can see numerous entries sets of entries: WAN Ethernet Interface is UP, Address= Site-to-site IPsec VPN tunnel is connected, name=tunnel_name Each time those entries are logged all services in the house would disconnect (VOIP, VPN to office, etc.). I rebooted all equipment several times, tried changing MTU, and several other settings with no luck. Reverted back to 126.96.36.199 and the issue did not reoccur.
I hope you are doing well. You probably has this information already but I would like to let you know that there is already a new firmware release 188.8.131.52 in which there are some fix that you can double check on this release notes
