[cisco-voip] problem with 7921g wireless phone

[venkata sashank]

Hi,

I have uc520 and 9 ip phones and 4 7921g wireless phones. The 9 ip phones
are working fine but there is an issue with 7921g ip phones. Out of 4 2 wifi
phones are registered fine, but the other two are saying locating network
services. and they come up saying connection failed. i have given the same
config on all the 4 ip phones. The two phones are giving the same error. And
one more question does the usb cable for upgrading firmware for 7921g comes
by default or do we have to buy? Please give me some suggestions.
I am giving the devices list that i am using


uc520, dlink 4port wireless router, and 7921g phone
