so... how to fix this sir ?It means that the RADIUS server you configured the Hotspot to send accounting records to isn't responding. Usually that's due to a mismatch of shared secrets, or incorrectly configured NAS/server IPs.
thanks for you fewi, I think you can understand what I mean, once again thank you and sorry for the english language. OKYes, a 750 can handle 6 megs of traffic just fine.
Help with what? What's the question?
