If you're concerned with the score then yes you'll need to wait for the fix I mentioned. Otherwise try the other suggestions and see if that helps with the delay - I don't think it's related to your bufferbloat score at all. It's not a case of better hardware in this instance.

Possibly, it is a big change from the previous version so it is worth a try

As in a bug on our side which we'll resolve. That's what I mean, having a good bufferbloat score won't necessarily result in an improved experience if you're experiencing bufferbloat at that time if you see what I mean. For the delay you're talking about people often try forcing servers further away which can help and some try throttling their speeds severely.

You don't need to keep updating that list, as it's located on our website, if we make a change you'll see that change. That's why it isn't working, QoS needs to be enabled for the Adblocker to work.

Your ISP may be prioritizing IPv6 over IPv4, as for the bufferbloat issue with IPv6 I think that's due to a bug we're currently looking at. I wouldn't worry too much about your bufferbloat score. Bufferbloat/lag only occurs when the connection is saturated and with Congestion Control enabled that can't happen.

Very strange, I'll pass the log on and see if they can see any reason why this may be happening

As above, is that the list you've added? Have you disabled QoS fully at all?

Thanks for that, was OFDMA enabled by default? Could you check if you see the same behavior with Smart Connect enabled please?

Have you disabled WMM in Advanced WiFi settings by any chance?

That's very bizarre, not seen anyone have this issue without the connection methods above, has this always been the case for you even after a factory reset?

Are you using VLAN, PPPoE, IPv6 or DHCP identifiers for your connection?

Connection Benchmark isn't likely to show your speeds accurately but what do they show? It may be worth setting scheduled tests for Benchmark say every hour or so to see if it's picking up this instability as well.

Can you switch to devices and see if the same behavior occurs please? Do you have any Traffic Prio rules active? Thanks for the app bug, if you wait 10 seconds before going to another page does it save?

Okay go ahead and get access back if you haven't already, we'll see what we can do to reproduce it.

When the speeds are lower than they should be, could you take a look at the Network Monitor please and see if there is anything else using a significant amount of bandwidth at that time?

If you have Share Excess enabled that will be why and is expected behavior

Thanks for the list! The cloud can be done without a new firmware, I've already asked for that to be done. What QoS rules is Bandwidth Allocation disabling exactly?

Are there any other options it has at all?

It's quite unlikely both routers would have the exact same issue so I do wonder if it's something else entirely, where is the router located and are there any electrical / wireless devices e.g headphones etc within close proximity ~3 feet? Do you have a microwave closeish to it?

I'm not sure what it is for your model, it likely has a sticker on the underside with that information, it's probably 192.168.0.1 There won't be many options but I'm hoping it has one option specifically - Energy Efficient Ethernet

I'm saying on the Arris modem interface, not the XR

It's when Alex has a chance to do so, I will nudge him to get caught up.

Could you provide a screenshot of the page you're seeing there please?

It wouldn't necessarily but will keep your network as stable as possible should any device use a lot of bandwidth. Have you tried forcing servers further away?

Have you tried the suggestions so far such as fine tuning Congestion Control?
