Area 21 - stuttering?

subsantial packets loss

Hi, called 0800 561 0061, no issues reported. Broadband appears to be very unstable though.

substantial packet loss

Hi, I'll appreciate some help. Called 08005610061, no issues reported. Broadband appears to be, at least, very unstable.

Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)

Click on 'router status'
Copy/paste the data from each of the tabs. The forum software will remove the MAC addresses for you (you may need to click the 'post' button again).

[lotharmat]

Are they the only downstream channels you have?

I believe there should be 24!

[llanero]

Thanks for replying @lotharmat,

this is a Hub 2 - I recall they've come around to setup the Hub 3 but the engineer couldn't so left me with the Hub 2.

I haven't got a clue, otherwise, this is as far as the log shows unless I'm looking in the wrong place altogether.

[lotharmat]

Ah - Ok - I think the 2 is only on 8 channels (Someone will correct me if I'm wrong)

Even so - the post RS errors look way to high, indicating noise on the circuit.

Power levels look fine though but RxMER could be on the low side particularly on one channel - I'd say VM need to investigate more on their side or book a tech to take a look!

[llanero]

thanks Lotharmat, I do look forward to VM having a look at this issue - will greatly appreciate if you can mark it for someone to have a look?

Other than that would like to ask you whether that noise might be internal or external please?

[lotharmat]

I would if I could! Alas, I'm not a VIP / Mod

Noise could be external and at any point on the segment - Or it could be a bad connection internally.

Are all the connectors finger-tight from the hub to the wall?

[llanero]

fair point, thanks Lotharmat, but no one was using any devices here between 6 and 8 am (which is where incidentally the first spike of "noise" took place). Then between 9 and 13 there's been the same use (same number of devices and connections) as of when the second noise spike began.
