Upgraded to Full Fibre - Low Speed, High Packet Loss, No Resolution

Last Friday, we eagerly upgraded from 72mb EE internet to Full Fibre Gigabit (900) and have had nothing but issues ever since. We already had a Smart Hub Plus SH31B so EE didn't send new equipment.

We are seeing terribly slow speeds, EE's speed test within their own app often showing 2-4 Mbps (nowhere near the guaranteed 700 Mbps) and Openreach's preferred speed test site fast.com not going higher than 140 Mbps at all. ee.co.uk itself takes almost 2 minutes to load all the images, it looks like I'm back on dialup from the 90s.

Packet loss is unbearable and makes gaming impossible, and video streaming on netflix, disney+, amazon prime video is impossible as it constantly buffers, seemingly due to the packet loss.

It's been almost impossible to get any support from EE's "Tech Guides", after the usual "lets try rebooting your router" they want to schedule an openreach engineer to visit. We've had 2 openreach engineers visit now, both have run multiple tests including their full SFFP test which show the line itself reaching speeds of 825 and 900. As soon as we reconnect to EE, speed is crawling again. Openreach have replaced the ONT, swapped the fibre to another port on the CBT, and confirmed no faults or alarms have been noted on the line. The light reading on the fibre into the property reads -15, which is meant to be a good strength. Openreach also rebuilt the config their side, but no change. 

Openreach tried to get through to someone higher up at EE to escalate and were told EE would send a new Smart Hub Plus SH31B, we waited for this to arrive and it didn't make any difference either. There literally is nothing else we / openreach can do at our property to eliminate issues so we're stuck hitting a brick wall trying to get EE to investigate further.

What makes it worse, also last Friday our next door neighbour had their full fibre upgrade, 500 Mbps through BT Retail, and they are getting their full service and not experiencing the same problems. They are connected to the same CBT as us (its just us 2 connected as it's only just become available in the area)

EE tech guides claim they've never heard of anyone have such issues, although the Openreach engineers hinted that the majority of their repair calls at the moment are to EE customers with issues not too dissimilar to ours.


Has anyone else had similar issues on EE's Full Fibre service and reached a positive conclusion with EE? Any advice on how best to escalate this would be appreciated

Just to close this out, after 4 Openreach engineer visits, all whom were very professional and carried out all their checks even though we had an extensive history on our account proving the line was fine. In the end I had 4 openreach engineers, 3 replacement ONTs, new cabling, port switched on the CBT, config on Openreach's side rebuilt 3 times, but after all of this EE still wouldn't escalate to anyone at BT Wholesale who could fix the actual problem higher up the chain than openreach.

I cancelled within the 14 day cooldown period and had Sky activated this morning. Zero packet loss, full speed from Sky on the exact line EE couldn't service.

Don't let them fob you off that it's an openreach issue if the openreach engineers have been and confirmed their equipment is fine. Theres an issue at EE / BT Wholesale which they are refusing to acknowledge / deal with

I am seeing similar on a new Full Fibre install from EE. EE speed tests within the app show 2mbps download when I am guaranteed 700mbps, and EE have zero interest in fixing it 7 days later. We've had 2 openreach engineer visits, swapped the ONT, Smart Hub, all cables and yet still no fix offered. Our neighbours had Sky full fibre installed the same day as us, and aren't seeing these issues.

The core servers where I'm seeing high packet loss are all around the same range

62.6.204.98
62.6.204.99
62.6.204.100
62.6.204.101

Did anyone get anywhere with EE tech support actually taking these reports seriously? Gaming, video streaming and video calls are all affected as the packet loss is pretty constant throughout the past 7 days at least

The addresses that you mentioned -

62.6.204.98
62.6.204.99
62.6.204.100
62.6.204.101

Are all core routers in the main BT core network - AS2856

I have now tracked down that some, if not all the drops that I was seeing on my EE router were not on the local copper or fibre section but were on the BT core network or where Openreach connects to the BT core network run by BT Wholesale (if I remember correctly).

Openreach can do whatever they do on the local loop (copper or fibre) and it will not effect the situation with some of the drops; if not all the drops.

There seems to be now process or procedure in either BT Retail or EE to report this type of issue and even if the front office accepts it there is now way of getting it fixed unless you escalate it to senior staff in EE or BT Retail.

This might even get worse with the greater number of customers going through these core routers. I have noticed on my connection that they do re-router the connections into the core regularly, but after a while they go back to the high latency and drops.

I have attached the latest monitor of the path to SamKnows, who provide monitoring for OFCOM. Not Good.

any idea how best to escalate this to someone who can look into it?

I can't get past the "have you restarted your router" followed by "we'll send an openreach engineer" loop. I've had 2 ONT boxes, 2 Smart Hub Plus routers, 2 new ethernet cables, 2 openreach engineer visits and still haven't reached anyone who can actually look into the issue. I'm on the 900mbps plan with a speed guarantee of 700mbps and EE's own speed test in the EE app reports just 2-5 mbps download speed, with a continuous 5-7% packet loss when gaming or video streaming

Did the Openreach engineers give you any hint of where they thought the issue was?

I am assuming that you did your speed tests on an ethernet connected device, is that correct? If it is via a WiFi device, what device was it? 

The only way I ended up getting something done to improve the situation is to contact them (EE front desk) again, again and get them to make a formal escalation out of it. They have wasted so far  just a few hundred pounds getting Openreach engineers out to the issue as Openreach charge EE and BT Retail for all calls that are made on the Openreach engineers. The equipment will just go into the pool to be refurbished, fixed and sent out again.

Make sure you have all the VOL case numbers that have caused the actions on the 2 ONT boxes, 2 Smart Hub Plus routers, 2 new ethernet cables, 2 Openreach engineer visits as they will be on your customer services record for EE / BT Retail. You can then say to them these are the cases etc. and nothing has happened.

OFTON can take the complaint but it only goes into the list for their stats.

The Ombudsman Commission Communications, you can go to but it takes a very long time. EE would have to not be able to fix the issue, EE would have to send you a "dead lock" letter saying hey couldn't get it fixed as well and then it takes a long time for the Ombudsman to go through their process.

Please don't ask in public area how I know all  this but I do,

Please keep me updated on how it is going as a FTTP (fibre to the home) based broadband should not have these sort of issues.

The openreach engineers believe it's somewhere on EE's network, they ran i think SFFP tests from their phones and when EE's kit was bypassed, the line would display 825 mbps download and 110 mbps upload. As soon as it's going through the EE network again, speeds are 2-5 mbps download and 110 mbps upload.

It feels like it's an EE configuration / provisioning issue as our neighbour, connected via the same CFT, is on a 400mbps package and is getting their full speed and not experiencing the same packet loss. They are with BT

You'd think (and hope) EE are getting alarms and alerts about the packet loss and slow speeds on their kit. Hopefully they monitor it once in a while

@evans57   not much to see there, no packet loss, just those routers not responding to pings.

Not sure the Openreach comments help, EE like BT Retail use BTW's core network, this really needs investigating by 2nd line, good luck trying to get hold of them.

There is definitely packet loss on the line, games skip continually, video streaming buffers continually, video calls stutter as they catch up

I understand about the SFFP test. It really only tests the Openreach part of the network where it connects to the access layer if the core network (BT Wholesale) in your case. 

Unless there is an issue in the copper / fibre Openreach part it will come up clean like it did in you case.

It was specifically design when Openreach was setup to look into the Openreach part of the BT Broadband solution as well as all the other broadband companies that use Openreach as their access layer. e. g. Vodafone uses Openreach for it's copper broadband solution.
