Having a lot of issues with pages failing to load on their first attempt, in game disconnects and generally frustrating internet to use.

This is happening on wired and wireless computers.

Below is some WinMTR that is showing a lot of packet loss to the fritz. I also have seen timed out packets in cmd with a ping -t to the router.

Done the usual restart of routers, check latest firmware, tried alternative cable to router.

I get very similar results to the below also on Wifi

While your MTR traces look okay because the destination hops show 396/397 and 397/397 and 390/392 minimal lost packets, time outs in cmd with a ping -t for packets destined to the router/Fritz IP point to an issue on your internal network... do you have another router you can try? I think Activision/Blizzard games only use IPv4 so you don't have to set up IPv6 for testing in case there is some interface flapping on your LAN. Does your issue present only during evening peak times or does it also happen (at off peak times) during the day?

Also - do they really hand out 111.69.69.68 for DNS to CG-NAT customers? Surely there is a 100.x.x.x IP for a DNS resolver that is a single hop away.

Noticing it during the day and evening.

The 111 IP was just a random pick from some other posts to run for a comparison (connection is set to default ISP DNS)

No other router on hand to test at the moment.

Is it normal to have so many dropped packets in WinMTR to the fritz? I've run a couple for longer and seems to fall on ~30% loss.

The BNG is ~20% loss on these runs

A snapshot of some ping -t to the router - cant say i've seen spikes in ping like this direct to the router. No other activity on the network during this time (no updates, streaming etc, just idle mobile)

As long as the loss does not carry on through to subsequent hops there is no issue as you are still only getting less than 1% loss toward the target/destination hop most likely due to Wi-Fi losses.

A few things come to mind:

Try changing the ISP preset on the Fritz to "Callplus" as described in this thread:

You say there are issues with pages failing to load, do you get any error messages e.g. ERR_CONNECTION_REFUSED ?

The page errors would be
ERR_CONNECTION_TIMED_OUT

I've just made those changes - Still got some times out page loads.

TY for explaining a bit more on the loss rates

high packet loss on the first hop makes me wonder if there is a problem with your router or the NIC or the cable between your computer and the router or a switch in between if there is one. if wifi, obviously we blame that :)

Replicated it on two PCs, one on Wifi, one on direct cable to the Fritz. I'll try get a loaner router or something to try in place of it

How is the Fritz connected back to the fibre box (ONT)? Power cycle the ONT and also try an alternative cable between ONT and Fritz (try an alternative power source/outlet for the Fritz i.e. move the Fritz closer to the ONT if you can).

How frequently do you experience the disconnections and when did it start? Is there any pattern to the web sites that go down (e.g. some sites always work but others are intermittent)

Both units are very close - Ill try replace the ethernet cable between them - has the cable that was supplied when fiber was installed

I've power cycled each unit individually and everything at once with a decent off time of everything as well

Fritz reports no reconnection in logs, and internet uptime is good

I notice it mostly when gaming(WoW) with zone changes, they fail regularly (feels like ~50% of the time). We have two players and can generally be playing with no issues, but zone changes must do something a bit extra

General web use is just frustrating - very intermittent, can be smooth as for a bit then it will stop, and then work fine again.

Been noticed for maybe 2 weeks

I once had an ethernet cable fail that had been working for years, so it does happen, but it's probably rare. Replacing the cable then trying another router is a good approach.

Replaced the fritz router with a new one, - Still having the same issues.. logged with 2D. Either the ONT or something else somewhere further up the connection

Considering the loss is to your router the issue is within your network, not with 2degrees.

to me, looks like you’re still using Wireless over Ethernet.

Chorus will charge a no fault found fee in this situation. You need to figure out where the loss is. Could be third party antivirus on your computer inspecting traffic, could be a faulty Ethernet cable, could be you think you’re using Ethernet but in-fact are using WiFi. Do more testing and ensure that testing is across multiple devices and eliminate things like switches off your network to ensure that’s not the cause.

appreciate the reply, but the issue is persistent after replacing the fritz, ethernet cables and happens on wifi+cable on multiple devices and device types

Issue occurs on multiple desktop PC. On Wifi and ethernet direct to the fritz, as well as mobile devices.

I've removed all other components on the network and experienced it with just the one PC connected to the master fritz

The ethernet cables have been replaced, including between the router and ONT.

Since replacing the Fritz, the loss packets to the router have gone, but there is still connectivity issues/page load issues.

It does seem to be when a page/app/game is establishing a connection rather than general loading - Things like logging into battle net. Shopify, Trademe. Starting a youtube video, stream - often fail to establish, but once a stream starts it runs fine, while pages will sometimes fail to load at the same time.

Taking a divide-and-conquer approach and supposing the issue is at the ISP end you could test by purchasing a static IP ($10/month) to rule out any potential CG-NAT issues.

This recent post seemed to suggest CG-NAT can affect gaming:

Just to add as well, putting the desktop onto mobile hotspot (with wifi turned off) runs smooth - mobiles on 4G, no issues at all, flick it back onto the wifi and its back to issues

ForumLurker: Since replacing the Fritz, the loss packets to the router have gone, but there is still connectivity issues/page load issues.

Your first hop (to fritz.box) or to your router is suffering packet loss.

Doesn't matter if you've replaced your router or cables here - your testing concludes this is still a factor. This is NOT your internet service provider, this is within your own network if this is the case.

Test to your router by pinging your router. If there is still packet loss to here then it is your computer or something between your computer and your router. It is very very clear in your first post especially this may be the case. Test this and confirm you're getting 0% packet loss and a stable ping. It should look like this:

C:\Users\micha>ping 192.168.2.1

Pinging 192.168.2.1 with 32 bytes of data:
Reply from 192.168.2.1: bytes=32 time<1ms TTL=255
Reply from 192.168.2.1: bytes=32 time<1ms TTL=255
Reply from 192.168.2.1: bytes=32 time<1ms TTL=255
Reply from 192.168.2.1: bytes=32 time<1ms TTL=255

Ping statistics for 192.168.2.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

Note the <1ms? Your pings above don't look like that indicating you're using WiFi more than likely and are not connected via Ethernet to your router.
