LWAPP won't joint controller. Possible US/Mexico Issue
I have some LWAPPs in Mexico that will not join a controller set to MX country code until I first join them to a US controller, let it update the firmware, then join them to the MX controller. Is this normal? It seems very inefficient to do it this way. Any help would be appreciated. Thanks, Dan . . .
Re: LWAPP won't joint controller. Possible US/Mexico Issue
No, this doesn't sound normal at all. I have not worked with AP's in different countries (Canada only :) but it sounds like you have some sort of mix and match between Country codes on the AP's vs WLC. Maybe you could look into what Country Code is set on each WLC. In WLC 184.108.40.206 and later you can set the controller for Multiple Country Codes. Maybe this would help;
