I went through router settings, and DHCP is on, no MAC filtering is happening. Any ideas? Short of setting my router to completely normal settings?
@paravorheim are there free IP addresses for the DHCP to lease out? Is the LED flashing green RAPIDLY (very fast blink) or MODERATELY (about twice per second)? How far is the Photon from the router?
Try disabling your firewall. my Xfinity router blocks port 5683 (outbound CoAP port) at all but its lowest firewall settings, and a Photon will never connect when thatās blocked.
It is a very fast blink. @ParticleD, I disabled my firewall completely and still no connection. Unless my modem or ISP is blocking that port somehow, which doesnāt make sense to me.
Itās difficult to pinpoint the exact cause without having access to everything that youāre working with, but the fact you were able to get it online with your hotspot and not the router seems to imply the router is still not allowing something through for whatever reason.
I would think itās unreasonable to think your ISP is blocking the port or protocol, so Iād be inclined to think thereās something on the router thatās not playing nice. peekay123ās suggestions donāt seem unreasonable either in terms of potential causes.
