Base station and wifi connection

I’ve seen quite a few postings from people who have had difficulties going from Ethernet to wifi with the base station, but I still have not seen a definitive solution to the problem. I’ve tried several times to connect my base station to my mesh wifi (yes, I did change the setting of the router to only broadcast 2.4 GH) but when I remove the Ethernet cable, the base station just flashes blue endlessly. Has anyone come up with a solution to this problem?
