I purchased Synology RT2600ac router and a Netgear DM200 modem because one of my suggested me. After setting them, I was enjoying hassle-free web browsing but the main problem arise after updating as my Synology router is not connecting to Netgear modem. When I use only the modem, my desktop PC works fine but when I plug the Synology router in, there exists no internet. I have tried a hard reset of the Synology router but still, Synology router is not working with Netgear modem. Help me guys to troubleshoot this problem!!
