Help interpreting my BQM

Hi, we have been putting up with random dropouts throughout the day since joining NowTV broadband - no problems before with Plusnet. I called customer services but was told the line is good & they cannot do anything.

I set up a BQM & was hoping someone could help decipher if it's showing anything untoward ?

Thanks for any help

Unless you're hammering the line, that is very much *not* normal.
(1) You have 100% paxcketloss for hours - oddly it seems to have a pattern where it very slightly improves every couple of hours.
(2) You are seeing very high maximum latency - this can happen if you're hammering the line heavily.

Are you sure that's your IP and not dynamic and pinging something else?

Have you tried an 'mtr'? this may show you how the latency varies to different destinations.

Going to a website like https://ip4.me/ will tell you what public IP address you're being mapped to - check this matches what you've configured for BQM.

If you were behind a CGN then that would be the address of the CGN box, not the address of your own router. However, I didn't think NowTV were using CGN.

I am assuming that you're BQM'ing the IPv4 address? Since they are part of Sky, NowTV might be doling out IPv6 addresses too. There should be no issue with BQM'ing that, I'm just interested.

we have a similar page (thinkbroadband.com/ip) and we take the IP by default I think when you add a sensor - We will ping an IPv4 address if you supply an IPv4 address.
Best way to test would be for you to unplug your router when you're seeing non-red for 2 mins.. and then back in.. if you see a 1-2 pixel wide red streak then it's likely to be correct IP. It may take another couple of minutes to update the graph so wait before you check.

Sorry Im just learning how to do all this, I'm prob doing it wrong.

When I set up the BQM I just used the IP that was auto detected already & left it as that. It was/is an IPv6 address. The 100% red on the graph corresponds to when my computer is off.

I've just checked my IP address with https://www.thinkbroadband.com/tools/what-is-my-ip
& it is an IPv6 address but it is not the same as what is in the BQM. So yes looks like I am doing something wrong. Ive just set up an additional BQM to monitor the new IP.

Thanks

Because you have a Sky/Now TV router you can make that respond rather than your PC, you can tweak the IP address like below, just replace 'xxx' with what you have. The 'xxx' may represent 3 or 4 characters between the colons as leading zeros are not required.

2a02:xxx:xxx:xxx::1

I would want to check your router as well as computer to rule that out. As per dect's reply try to set up the router and see what that shows.
v6 routing will be independent of v4 so any troubleshooting needs to be v6. If you know your v4 address (and it's on your router) this may be useful to compare to track down the problem.

Edit: I've checked based on your forum IP address (where you're posting from) based on Dect's suggestion and the result looks much more normal. I do see some very high latency packets so the max might still be high but it's a lot less variable than your computer's IP. This may not be as visible on the BQM graph as you'd need to look at the average variations. Set that ip and see what it shows on BQM over a few hours.

Is your computer on wi-fi by any chance? This might explain the results too.

2a02:xxx:xxx:xxx::1

I have two set up, one uses:

2a00:xxx:xxx:xxx::

and the other:

2a00:xxx:xxx:xxx::1

the second having the final 1 added although both are almost identical.


edit to add:

I wrote this over an hour ago, just after your original, then got distracted

If you can get into the router's web admin page and see what IP address it has for its WAN interface, that's the safest one to go for.

If both of them show the same latency, they're probably both on the router (e.g. WAN and LAN addresses).

However, xxxx:: and xxxx::1 *might* be the Sky side of the link and your router respectively. There are lots of different ways this might be configured and I've not see a NowTV connection in action.

In this case :: ending IP is stable too. both ::0 and ::1 are getting consistent ping times.
