Internect connection issues

[Cwilson1985]

Internet Keeps Dropping, wont reconnect, and says hub seems to not be connected properly.

If i restart router as suggested etc it stays the same, i have to leave it off overnight for it to work for any period of time

Check for a known local fault on 0800 561 0061 - it is an automated service.

Upstream Power levels are all above the preferred range (engineer fix required),   Downstream has also logged high number of errors.

[Cwilson1985]

Do you understand the jargon/numbers above? 

[Client62]

Yes indeed, there is a Gig 1 connection & possibly using a Hub 5.

The Downstream Power levels and SNR are both OK, though quite a number of hard error have been logged.

The Upstream Modulation mode of QAM 64 is correct, but the Power levels are too high on all 5 channels  i.e. the Hub is working very hard to be heard at the street cabinet.

This could be a locality issue or a fault just on this connection..

[Cwilson1985]

Ty, ive rang them but ive got to wait 24 hours, as they cannot run any more diagnostics before the.

Apparently can oy do them every 24 hours... Even tho ive followed everything they have told me to do, for the last 4 days. I now have to wait

[Cwilson1985]

Just rebooted after leavibg the router off for an hour, abd these are the

It is good to keep the Hub turned on. 

If the Hub has may connections / disconnections VM can see that needs attention.
