Upgrading Autonomous to Lightweight

Unanswered Question
Jan 30th, 2008

Hey Guys,

I was wondering if a 1220 AP (AIR-AP1220-A-K9) is capable of converting to lightweight mode. The AP does B Radio only (AIR-MP20B-A-K9). On the Cisco site it says that B-Only Radio is not capable of converting to ligthweight. I just need a confirmation if this is true or not? Thanks.

I have this problem too.

Hi Tyler,

Sadly this is correct.

The 1200 Series can be upgraded to LWAPP with the G Radio model listed below;

Solution Requirements

Migration from autonomous access point mode to lightweight mode is possible on these Cisco Aironet access point platforms:

All 1130AG access points

All 1240 AG access points

For all IOS-based 1200 series modular access points (**1200/1220 Cisco IOS Software Upgrade, 1210 and 1230 AP) platforms, it depends on the radio:

if 802.11G, MP21G and MP31G are supported

if 802.11A, RM21A and RM22A are supported

The 1200 series access points can be upgraded with any combination of supported radios: G only, A only, or both G and A.

From this good doc;


Hope this helps!
