Re: No Ranging Response received - T3 time-out

Try a reboot to see if the Hub can renegotiate a better connection using this method ...

Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.

While the Hub is powered off go around all the accessible co-ax connectors inside and outside to ensure that they are finger tight.

Give it a good 5 minutes put the plug back in and switch the Hub back on.

Allow the Hub a few minutes to fully restart then try your connection again.

Re: No Ranging Response received - T3 time-out

HI Mike

Thanks for the suggestion.

I have done this many times, spent most of new years eve doing this. Although i have not checked the connections outside.

Based on the logs i posted do you see any issues with the data, that would point to a problem?

Thanks

Naeem
