I spent 3 hours last night google search forums, talking to Xnet and Snap tech support. No one really knows why the 7390 is not connecting to Xnet ADSL.
I have updated the 7390 to the latest firmware.
The Fritzbox itself shows a DSL connect is live, but apparently it is not trying to register with Xnet (sorry for laymans explanation). Xnet said that they could see no activity from their end.
The modem currently used by the household is a draytek 2710VN, however the modem is having issues with the LAN side of things hence me trying out the 7390.
I'm at my wits end with this. I'm starting to wonder if the unit is faulty or simply incompatible with Xnet.
