Hi,
Here are the answers:
1:Can we run it with mixed mode like the device which has 802.11ac/N Compatible run with 802.11 ac/n mode and device has 802 11.B/G run with 802 11.B/G mode ?
Yes you can.
2.We will run our all Cisco LAP1242AG-N-K9 Access Point with External Antena AIR-ANT24020V-R through Cisco WLC 5508 please confirm.
You can. Info: 1242AG last SW support is 8.0.x. so your WLC must not have the higher version then this otherwise your AP will not join to WLC.
Regards
