no ranging response received - t3 time-out

Hi

This has been going on for quite some time (months) and has reached the point of being super annoying now.  I'm having problems connecting to any pages without having to refresh multiple times and can no longer use Steam to play games.  Tonight has been really bad.

I have copied the logs:

Re: no ranging response received - t3 time-out

To be honest, it's probably not the Hub but rather a bad cable connection between the Hub and the street cabinet. To start with just go round and check all the connections are in nice and tight including in the 'omnibox' on the outside will where the cable comes in.

There's nothing obviously too wrong in the network logs (except you left your public IP address on view, which is a bit unwise and it's too late for you to go back and edit it out so I've alerted the mods to take a look and remove the address just to be safe), but your downstream power levels are on the high side (in fact some of them are over the upper limit) and the upstream are a bit low - plus the upstream is only running at 16 QAM which is often an indication of interference getting into the connection.

By the way do you really only have eight downstream channels? What speed are you supposed to be getting?

You will probably need an engineer visit to correct the power levels and test them, you can either call in to customer services and insist on one or hold on for a member of the forum team to get to this thread and offer to get in touch with you directly.

Hi John, thanks for the help

I'm supposed to be getting 100MBs down speed - when it's working that's what ookla speedtest says I get.

The connection is intermittent and has got a lot worse since my next door neighbours were connected up to Virgin.

Have setup a logging service to see what happens over 24 hours.

Will check cables.

Re: no ranging response received - t3 time-out

I would start with the basics, are you experiencing the dropouts whilst connected directly to the Hub by ethernet cable or only on wirelessly connected devices?

As said the downstream power levels are a tad high, the upstream power levels are fine. The power levels are possibility an indicator that you are fairly close to the street cab.

Which Hub do you have? The stats suggest a SH1 or one of the SH2 variants.
I would test with a device connected directly to the Hub by Ethernet cable to test the actual internet connection if not done so already.
Do the Hub's lights change behaviour when the connection drops?

Hi

Thanks for your time.  I contacted tech support today, they tested the home hub and want to replace it, they say it's old.  I'll go with this and see if that sorts the problem out.

I'm old fashioned, wired all the way.
