Vivid 500 slow speeds.

DC
On our wavelength

Hi, I'm getting download speeds as low as 45mb on my vivid 500 connection. Spinning circles when we're watching TV and Movie apps at various times of the day. I think I've done the below correctly, any advice would be appreciated:

Down powers are a little high - but within spec there are afew RS erros that need checking so can you do the below.

Also you havent said, are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection/Hub related?

What Hub model is it? What are the various Hub lights showing/doing when this happens?
________________________________________________________________________

Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.

Thanks very much for the quick and detailed response John. I will run through those checks and report back. It is happening on both. We have a Sony Bravia TV connected directly to the hub via ethernet. We quite frequently get dropped connection messages or spinning circles when watching apps etc. The same on the WiFi linked TV in the bedroom.

OK lets see what happens after a clear to 0.

Also, If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

Thanks John. 

Which IP address should I include for the monitor? I can hook a laptop up and leave that on?

Hi John,

I done the reset on the router. When it restarted the WiFi wouldn't work and I ended up having to do the 10 minute hub reset routine. Anyway. Network Log below. I note it's still showing data from the 20th, is that correct?

Had the same issues trying to watch STV and Channel 5 players last night on the TV connected by LAN. Spinning circles and no Internet connection error messages. Mostly between 7 - 9 pm 🙁

Hi Nat,

To my knowledge John is not a VM employee, although he is a very insightful and helpful person. I would appreciate a colleague taking a look. I did receive a PM about average speeds on a different thread but that's something quite different. If you take a look at the chart I have linked in an earlier post you will see some of the activity on connection over the last few days of which John has pointed out some issues of interest.
