1832i ME not joining controller

Hello

I have a 3800 running as a ME and its running as a controller, which works fine.  I have added additional 1832i which is converted and image is matching that of 3800.  To power the 1832i i am using the AIR-PWR-C= but it won't join the controller.

 

I keep getting "Max retransmission count exceeded, going back to DISCOVER mode."  I am not sure what i am doing wrong, any help would be great. Thanks

Re: 1832i ME not joining controller

Here are my answers:

 

1. yes

2. Yes it will work if you both APs (ME WLC and 1832 ap)in same domain.

3. -B and -A domain belongs to USA thats the reason both working together.

4. Canada regulatory domain must be -A. If you use -S domain in canda then its not legel and it will not work.

Re: 1832i ME not joining controller

AP(1832) is with -S domain which is not correct and you are running US as country code on WLC.

 

To connect to US coutnry code wlc you must AP with -B domain.

 

Edit: -S domain is used for Brunei, Hongcong, ..etc

Cisco Employee

Re: 1832i ME not joining controller

So the AP needs to be "B" in it? instead of S

Cisco Employee

Re: 1832i ME not joining controller

My 3800 has "B" in the model number and i have 2800 which are "A"

This AP has -S domain, whcih will not comatibile with 3800 (-B) domain. It will not work.

Re: 1832i ME not joining controller

Thank you for reply so in summary i need to match Domain of AP with Domain of controller? Could you please answer my question below.

1. Since my AP Controller is B and this AP is S, is this why its mismatch?
2. What if i make the -S domain the controller and have the other -S AP join this controller, will that work? and i totally remove 3800 from network?
3. How come i can connect AP Controller B (3800) and 2802-A and they both work together?
4. If i am trying to make these work in Canada with 3 x 1832 all 3 with -S domain will that work in Canada? If controller is hosted on one of the 1832?

Re: 1832i ME not joining controller

Thank you for that.

2. So what prevents me from changing the domain on the ME controller to that of -S to match AP? i just tried that and its working

My speed is running great on all my devices except the iPhone X and Apple Tv, i can't seem to get more than 50mb while other devices are getting 400mb on wifi, connecting to same AP. Anything to check here?
