Thanks, will do.
All went well, in the end I connected the smart hub 2 for the changeover and then connected the vr2100 an hour later. Interestingly the the vr 2100 synced at 25Mb compared to 18Mb on the smarthub. Been running for 24 hrs now with no drops and pkt errors in single figures. I am 1.7 km from the cabinet so it has exceeded my expectations. Hopefully it remain so! Thanks for your inputs.
