USB Share not accessible when WAN is down

My internet went down for a few hours, so decided to watch a movie stored on the USB drive attached to the XR1000 router. While every device in the house was able to make a connection to the router, ...

    Welp, seems I got the share to work as expected with the WAN cable unplugged. Darned if I can fully explain why, but here's what I did...

     

    I noticed in Windows Networking that my Sony 4k player UBP-X800 was still connecting via wireless from the last time I had it check for firmware updates. It showed as a media player and media source. Looking into the settings on it, apparently by default it had enabled it's media server and also network access control using UPNP. I turned all that off, and disabled the wireless conection on it so it no longer was connecting. I then turned on, then off, UPNP on the router under Advanced settings, which seemed to do a long reset each time. I'm guessing it was resetting some kind of networking cache and in the process flushed out the bad junk from the Sony player. If I had to guess, the Sony player was doing some kind of loop on UPNP bogging down other services....maybe.

     

    I'm glad that my previous suspicion that the router was disabling SMB share functionality when WAN is down was wrong. Thanks to all who put time in to help work through this.

Whatt brand and model # USB drive and drive size do you have connected to the router? 

Maybe try a factory reset on your router and setup from scratch. I would try setting up with out it being connected to the ISP modem. 

 

MS Edge caches was cleared prior to connecting to the routers web UI. So all was new and clear with the browser and saw no issues using IP address or host name to access the web ui. 

 

Seems like your router maybe in some bad state or there is a mis-configuration at some level with your environment that seems to be maybe causing problems. 

 

Extreme altternative would be to try a different router with your USB drive and see the same problem follows on that router as well.

 

The XR1000 is not working for me to access the web ui. Only 192.168.1.1 or routerlogin.net. I've always used the IP asddress with out fail.
