2.4 not working on router
i have a sengled hub that requires 2.4 i have reset router and device it cant find the router and it right next to it. i even added the mac address to the router and it cant connect it shows 2.4 is working on router. i have had this hub for couple of years and never had problem getting it to reconnect until tonight.
I found something about disabling the 5ghz on router still says it cant find 2.4 after rebooting both device and router.
