I have this issue which I once corrected by following a reset procedure for my Mikrotik Hap Routerboard. It involved no wifi being present so I reset the router to factory settings. I did this by following a YouTube tutorial. The problem occured yet again which had me change a few things on the router, had no idea what I was doing.
So I went back to resetting to factory settings, followed the steps yet again, wifi worked although I could not connect any devices to it. My POE is plugged into the POE port (1) and another ethernet cable into port 2 which goes directly into my PC. The internet works fine.
However once I try to connect to the router via wifi my mobile says "Failed to obtain IP address". Thought that changing the DCHP to static would help but it did not. Might not have entered the correct IP or gateway but I entered those displayed on the router itself. I have the router set to automatic internet detection. The same procedure I followed when I 1st encountered the problem. This time around the wifi is there but my mobile or any wireless device can't get an IP address.
Is there something I have changed unknowingly in the IP settings? Maybe someone can link me a guide? I dont know why it doesn't work after I followed the exact same steps as before.
Thanks
