I have a single device in my network that will connect to the wifi (a separate box) but not pull any data off the network and I believe it’s my Mikrotik 750GR3.
This started to happen only recently after having worked for a couple of years with no issue. I thought it was the wifi, so I swapped it out - it wasn’t. I thought it was a recent routeros firmware upgrade (the latest test version) but a downgrade to the latest stable release (which used to be fine) didn’t cure the problem. I can’t find anything in the settings that would prejudice one device over the others.
Is there anything anyone could suggest or a way to snoop on what’s happening with this device? It negotiates the wifi connection fine but fails to connect to the WAN.
Steps would be to determine its MAC address, check that it is registered as WiFi client, check that it has successfully accepted an IP address by DHCP (/ip dhcp-server lease print where mac-address~“xx:xx:xx:xx:xx:xx”), then use /tool sniffer quick ip-address=xxx.xxx.xxx.xxx to see whether it attempts to query DNS and whether it gets any responses.
That’s pretty common here, I’ve reverted to guessing. Here in particular, I’ve guessed that “it’s my Mikrotik” actually means “it’s caused by some issue on my Mikrotik”. Let’s see whether the guess was correct.
