1.6Gbit connection new smart hub (white, small box) sporadic issues? DNS MITM?

Hello all,

So I recently changed my service from 900mbit to 1.6Gbit and that involved a change of router and obviously the OR ONT on the wall.

Ever since having it installed there seems to be an issue with (most likely DNS issues). Whatever is loaded/playing/game continue to work, but I have spells where NO further DNS requests seem to make it through.

I totally forgot to nslookup during one of these issues, but I will the next time it happens (it's pretty frequent and annoying). I can ping 8.8.8.8 (google) whilst being unable to load any webpages on any device/browser. Thus removing the possibility of it being localised to a single machine/device as some were using the router, some were set to DNS over HTTPS and some were using Google's 8.8.8.8 etc. 

It is very much like the router is playing the MITM and intercepting the requests and then slowly, or failing to process these requests at all for a period of time which ranges up to about 45 seconds.

As I said, cached requests, or those already in process are fine, but even something as trivial as trying to watch a YT video is met with 45 seconds of nothing, totally unable to look up ANY address, but established connections and new connections not requiring DNS all work fine.

I'm not really one for conspiracies but I really feel like this new router is intercepting (MITM), attempting to do something with, and failing the DNS requests. This behaviour is only been present since getting the new Smart Hub (the tall, thing white one).

I did a quick google and it seems I'm not alone with this - is anyone else noticing this type of behavior?

Mixture of wired and wireless devices, same behaviour.

EE have promised to get back to me by around 1pm today, but I'm not holding my breath.

I have noticed my firmware has changed at around 3am on Saturday morning, but I can confirm this has not solved the issue.

I am currently running an independent DHCP and DNS service having turned the DHCP off on my Smart Hub Pro and this has not improved the issues under discussion.


This is my day-to-day setup. DHCP disabled on the hub and a wired Raspberry Pi doing DNS/DHCP duties (Pihole with a local Unbound instance). I've noticed none of these issues and I have Smokeping running on the Raspberrry Pi too, repeatedly pinging the hub and running DNS lookups to various sources - the graphs look clean.

I've just re-enabled DHCP on my hub and put the Pihole into standby to see if I can replicate what others are seeing with @ryajohnst's script.

I'm on Busiest Home with a 1.6Gbps service. 

Edit: script now running, will report back after a day or so...

So for now ive disconnected the ee router and extender and gone back to my older asus ax-11000 router which i had been using in ap mode previously.

Whats funny is since ditching the ee router all my weird anomalies have gone, my nest speakers respond quicker, my doorbell loads immediately instead of a few seconds, web browsing is noticeably faster and even though the asus router loses signal towards the end of my house it still feels faster.

I had high hopes for the ee router based on the spec sheets, but i really feel isps need to offer subscriptions without the hardware if whats being provided isnt fit for purpose, even offer no router, isp router or ubiquiti hardware at different price points.

@jasonpartington  Yea the way I think of it is all-in-all is these EE routers are selling on line for about £50.  So it's not mega-money lost - and if you already have a different router in the house (which we all do) it'd not really that big a deal as the other router just works *immediately, completely*.

Out of general principle I'd have liked to use the new shiny kit.  But when I plugged in my old router everything felt so much better, more responsive, immediate, no problems whatsoever.  

Plus all I do is wait for 3+ people to start writing on this thread 'Holy moly, that patch last night, I think it's solved it you know' and I'm back on the new kit again anyway.

If the problem was on the ISP-end (rather than on the hardware in my house) I'd have been TOTALLY GUTTED as I'm tied in for 2 years.  However as I can get flawless internet through EE just by flipping in a different router in about 4 minutes .. ach, it's hard to get mega-upset.

I think they offer the new router because the discount they must get for buying in 150,000, or 300,000 of them must be insane (like, I bet they're paying £20 per unit or something) - and their marketing guys are saying 'People want a new toy through the post, it gets the sales, acts as a 'differentiator' between ISPs, you can invent something called 'Gamers mode' which is another differentiator, so trust us, you gotta give 'em a shiny physical box of tech'.   

If they offered without the shiny new router, and it only knocked £2 or something off the monthly price (which I reckon is all it would, as it only cost EE 20 quid or so) - people might start to work out the shiny new box isn't a super-duper fantastic expensive must-have thing anyway.

@jasonpartington I have noticed Cuckoo broadband provide a eero Pro 6E as their standard router.  

@jasonpartington Just think what a more up to date Asus would do for you, You get what you pay for, and a ISP router is not that!

In principle you might be right @Britboy4321 , but some of us have network configuration which can be a pain to transition between two sets of routers, especially if you have some IoT devices and a few services like either HomeBridge or Home Assistant running.

Regardless it is clear that the latest firmware release for the EE router and extenders are currently borked. This will be impacting more people than just the more technically minded people in this thread. EE really need to get their testing game on as really this release should never have gone out to the public. 🙂

I've noticed, the problem doesn't seem to exist when you enable and use the "Guest" network on the EE router.

I know this isn't ideal but may be a quick fix for some people until EE get their act together and get it fixed.

How curious.

So, findings from my testing using @ryajohnst's script below. Note, my hub was rebooted around 2am so failures around that time are expected.

Wired desktop (~22hrs of script execution) - https://pastebin.com/cMGY6THq

Zero DNS failures (excepting hub reboot), Maybe 2-3 occurrences of elevated pings to external site but nothing concerning (still < 15ms) and zero loss. There's heavy upload on my line during early hours too when my desktop drives are backed up.

Wireless laptop, connected to extender that's using wired backhaul (~17hrs of script execution) - https://pastebin.com/xaAiNJ8c

Zero DNS failures (excepting hub reboot), more occurrences of slightly elevated pings to hub/external site but again, nothing too eye-opening and I expect variance due to the nature of Wi-Fi. A single packet lost at 3:09am. Script was terminated prematurely around 4am due to a Windows update.

So, I'm not seeing what others are reporting. Unsure if relevant but both my extender and the desktop are wired back to the hub via unmanaged switches.

I do have Guest WiFi enabled though so in light of @ryajohnst's latest observation, I'm going to try disabling it and repeating my tests...

@ryajohnst : sadly the issue still exists with the Guest network enabled - I do have this enabled myself and have the whole time as I do have guests that pop over from time to time and I’d prefer them to use that network.
