I have four Arlan 640's and may have had one or more fail. Is the Arlan 640 compatible with the Aironet 340 or 350, or is there a direct replacement for these units from Cisco?
It's kind of funny that your efer to "Aironet 340" as "new equipment" :-)
From what I see on google, the Arlan runs on 900Mhz so that's a totally different product. No-go !
