Cannot connect to DWC (wifi) but printer says wifi connecting
-
I have had this up and running a couple of weeks now. At some point I rebooted and ever since I cannot connect to the DWC. When I startup the printer the screen says it connects to wifi but I can't get to DWC.
I have manually reinstalled RRF and DWC using instructions here https://forum.duet3d.com/topic/9134/can-t-connect-to-dwc ; issuing M997 S0 and M997 S1 through direct connect to computer. No luck.Anybody see any issues? What should I try?

@EricE555 said in Cannot connect to DWC (wifi) but printer says wifi connecting:
WiFi IP address 192.168.0.100
I thinks it has this IP address. What URL are you trying to connect to in your browser? http://192.1168.0.100 should work, provided your computer is on the same subnet as the Duet. Can you ping that address?
On your computer open a command prompt window and send
ping 192.168.0.100and post the response Then sendipconfigand post the response. -
thank you for the reply.
I cannot ping the address. I don't know networking, my brother does though. I might have to get his help.
My wifi was not strong enough to reach here reliably so I added a tp-link RE450 in my room with an eithernet plugged in. then I configured it as an access point for the printer. It is up and running fine (as we know because the computer connects to it). It is putting out a wifi with the name 3dprinter. I guess I should try to access that with my computer or phone. I'll post back after I test that. -
It sounds like the Duet is on a different subnet than your computer. The RE450 is probably creating a new network and not bridging between the existing network and it's own wifi network. There might be some settings you can change to allow that.
Running the Duet in access point mode might be an option, but isn't as convenient.

Mystery Solved!
My switch had gotten bumped and lost power. So my computer happily connected to my wifi and continued to work but had no access to the Access Point that my printer was on because that AP was Ethernet. So now that my computer is back on eithernet and wifi is off, all is well. Whew!
