I’ve had Peplink 300 for ~5 years, and I love it. I’ve been using it with multiple ISP’s but all with a static IP configurations, and no issues. I just moved to a new house, and I’m trying out residential service from Comcast Xfinity and it works great if I plug it directly into one of my computers. But if I plug it into a WAN port on my 300, it never acquires the IP settings via DHCP, even when configured to do so. I’ve tried varying MTU, just about everything, nothing works. Is there a secret out there I don’t know about? Any help would be appreciated.
