Hello all,
I recently did a cheap(ish) upgrade to my home lab because I hadn't done anything for a while and my 2600 APs were getting a little dated. I bought a batch of 2702i's off ebay to lab with. The first AP I plugged in worked fine (with a date modification on my WLC *sigh*), and all seemed to be going well. However, 2 of the 5 APs I ordered only show one (5G) radio present (both in sh ver and in the interfaces tab of the AP from the GUI). I spent a couple hours trying to diagnose the frequency issues. They're just straight up missing the 2.4 radio, and surely that cannot be by design!? I don't think it's a WLC/Firmware/version problem (running 8.3.112.0 on a 5508, no issues ever with the WLC image), because three of the 5 I ordered worked fine. I can't even find a part number for a 2702i radio module...
Short of cracking the ones that are showing single radio interface (and effectively useless to me), is there any good diagnostic to run against these APs? I'm more R&S than wireless, but I've never run into a wireless problem like this... I'm suspecting the surplus parts vendor I ordered from sent me a batch of APs with burnt-out NIC cards, which would explain the price... is that even a thing? Is it common for these radio modules to burn out under heavy use? My used 2602s have been running hard for a year with no issues at all.
It's super late where I live (I've stayed up all night fighting with this). I'll check answers/reply in the morning.
Appreciate any help. Thanks.
