Nortel SpectraLink 6120 handset - 802.11 a/b/g capable
The phone can see the SSID in survey mode but does not appear to be able to authenticate or associate to the AP. No client records found in logs. Client displays "No Net AP Found"
5210 EWC running 10.31.03.0012
Trial and error:
We have tried turning off as many non-legacy features as possible, 20 MHz wide channels, enabling lower data rates, adjusting the DTIM (1,3, & 5), etc.
Phone is configured to use WPA2 PSK on 5 GHz - UNII 1 & UNII 3 channels only. Have also tested using the 2.4 GHz b/g and with same result. Have reset, changed, reviewed, and confirmed settings in the phones several times.
Any advice? Besides buying new phones...:)
