unsupported operation

[chrsfrm]

Hi Guys, finally having to admit defeat after days trying to set these up.
Basically my DG834G has all the lights on, including 2 hardwire LANs, thankfully so I can at least post here.
The WG111v3 seems to be the problem, it just will not allow me to connect via wireless. I have tried via Windows rather than Smart Wizard, also removing all security & passphrases, uninstalling & reinstalling using drivers from the Netgear site, all with no success.
Also Smart Wizard launches as a WG511v2 version!!! and always provides the error message "An unsupported operation was attempted".
Please can any of you experts help....I hoped Wireless would be an easy upgrade..but not so far.
Regards & Happy New Year,
Chris
