Ok,
This problem is very frustrating. I have installed the above two routers and everything seems to be working fine.
I have made use of the 3G backup and this will work fine along side or independantly of the ADSL Connection.
My problem is, wait for it.... I can not seem to get the 3G to kick in automatically when the Primary connection fails!!!!
Its all set up in Backup/fail over mode but when I disconnected the ADSL connection it will not trip over to the 3G. I however can start the 3G Manually.
Go figure!!!!
Thank you in advance for any replies.
