Here’s and update: The problem isn’t fixed but i’ve found why it’s happening. I have a Diskstation from synology a nas drive that won’t let me access the router pages on dumaOS. When I turn the Diskstation off, I can then access the dumaOS. Upnp is working fine all though it does sound like a port conflict. Maybe they’re trying to use the same protocol at the same time like ssh or telnet. Either way I can’t use my nas drive with your router. I’m about to give up on this router as it’s too much hard work to just getting it to work.
