Working on UC520w My Demo box. Pulled it out of storage in prep of a demo. Well ofcourse it decides to be a pain from beginning. I have tried three different laptops and the UC simply will not give an IP from DHCP. The only way I can communicate with it is assigned static ip on laptop. 2nd problem. UC will not allow me to do factory reset through CCA. keeps giving me a Vlan error for my static IP address. Tried on another laptop through CCA and also times out with vlan error message. So then I tried default through CLI just so I can get back to factory and start a new. CLI seemed to work until still needing to assign Static IP to laptop. Seems like a Vlan issue.
I should also mention I tried to TFTP an old config from PC. Well TFTP server times out also and eventually fails.
