I have a RouterBoard 433 with a 5GHz XR-5 radio card and a 2.4GHz XR-2 radio card, both running AP mode. I was running v4.17 but was having problems with clients staying associated to the 5GHz XR-5. The 2.4GHz XR-2 was working fine. I upgraded to v5.22 and my problem with clients staying associated to the XR-5 card seems to be better. Now I have no associations to my 2.4GHz XR-2 card. Any ideas why? All settings seem to be the same. I have upgraded the firmware. I have disabled then enabled the XR-2 card.
Thanks ... Jay
