I have an EdgeRouter POE5 connected to a microsoft surfboard cabel modem. Using 2 of the POE ports for UAP-AC wireless and another port going to a Cisco switch to distribute throughout our office. I setup the router with the wan2 + lan2 configuration, opened 2 ports for our VPN and NAS access. Everything has worked brilliantly for over a year, this router is absolutely bulletproof. Until recently...
We are now experiencing intermittent disconnections of our internet. Did some troubleshooting and have good internet when I connect to the modem directly, internet doesn't drop at all. Connect directly to the router and I get internet for a time, and then it drops. Powercycle the modem and interenet comes back for a time and then goes out again. This doesn't seem to happen and any set interval or specific time of day.
Anyone have any suggestions for further troubleshooting? I know enough to be dangerous, I'm no network engineer or IT professional, just a small business owner limping along as best I can. Any help would be appreciated.
