Hi,

Can someone point me in the right direction as to there is a substantial difference between these two connections. The second question would be is Connection B a bad connection ??

First off both are using exactly the same router (Netcomm NB6Plus4Wn)
Connection A is 1.2 km from the exchange, Connection B is 1.3 km from the exchange
Both have master splitters installed.
Both are connected to the Orcon+ Network on exactly the same plan.
A couple of differences is that they are connected to different exchanges and in the case of Connection B it is within an area which has been cabnetised. Connection A has not been cabnetised.

Any ideas why Connection B is syncing at almost half the speed that Connection A is syncing ?? Is a 34dB line attenuation setting ok or is Connection B seeing some feedback from the cabnetisation ??

Cheers for any feedback.

If you are already connected on an unbundled Orcon+ plan and your line is connected to a roadside cabinet then it is likely that the speed at which your modem sync's (your connection speed) will be negatively affected. This ranges from a small impact, through to (in a small percentage of cases) making your connection unusable. In the event that your connection is severely affected we are more than happy to discuss alternative options with you. This may include the option to transition back to our traditional Orcon network.
