5G Broadband Drastic Speed Drop & Throttling to 120mbps after Settings Changed by customer service!

I have replied to other peoples posts multiple times about this but thought I would start another post as well to keep up the pressure on Three as they are refusing to admit they are throttling connections, yet multiple users have posted on the community site about this and stating they can now only hit 120mbps download when they used to hit much higher, these are different people in different parts of the country, being impacted exactly the same.  

I live right next to the 5G mast in my area, literally 30meters away. When I first went with three 5G broadband in October 2022 and up until November 2023, I was hitting anything from 600 to 900mbps download, all the time, even peak hours, I still have all the results recorded on my Ookla speed test app/account on my mobile phone.

In November, Disney plus stopped loading on my TV stating I was out of region, nothing I did/changed could get it to load so contacted three to see what was going on, they advised they could fix the issue by making some changes to my account settings and to restart my router and try and open Disney Plus again on my TV. Sure enough Disney loaded after the they messed with the settings, but from that exact point on (14/11/23) my download speed is stuck at 120mbps, won't go any higher. It jumps sometimes to around 400mbps when the speed test initially starts and then immediately and dramatically drops down to 120mbps with a second or two and stays there, clearly this is throttling and limiting the download speed. 

I contacted them on multiple occasions over the next few months and they were giving me all sorts of excuses and said they had changed settings and to try again, and another said they were working in the area but it would be back to normal in a month. I ran a speed test every week and nothing has changed, stuck on 120. I have had a month refunded and a month half price but all this time they are still claiming they do not limit the download speeds which is obviously absolute rubbish.

As someone else has mentioned on the community site, when I do a speed test on my phone when I am not connected to the Home broadband, and I'm also with three for my mobile contract, I still hit the usual 500mbps+ and nothing has changed with the speeds on my phone, just my broadband from November onwards. 

At the time I googled and couldn't find any posts on this so thought it was just an issue in my area, but after a speed test earlier, stuck on my 120, I googled and found this. Now I know this is happening to others I am going to contact them again and keep up the fight! Since I originally posted this only a month or so ago I can see there are new posts popping up weekly from people experiencing the exact same issue, so it seems to me Three and rolling out this download throttling across the country now. 

For those that want to leave three, due to the speed decreases, who are stuck in contract, they agreed with me that I could leave with no charges due to the change in service. When you first sign up, you get 14 days no quibble trial to see how it works and what speeds you get and you can send back if you not happy. So, if the speeds you are getting now, do not match the ones when you first got it, you can argue this and say you want to leave without a charge!

A further update to this - I made three send me out a brand new replacement router only 2 weeks ago at the start of Feb 24, so I could rule out that being an issue. I have a brand new replacement router (Zyxel NR5103), brand new sim card, and nothing changed. exactly the same and stuck at 120mbps. I have attached screenshots of speeds tests below and you can clearly see the moment they made the changes at their end on the 14/11/23, and from this point on my speed has been throttled to 120mbps, when the speed only 3 days before that was 544mbps.  I have also added screenshots of speed tests from Feb 2023, compared to speed tests from Feb 2024 and the differences are striking. My speed used to vary, as non throttled speeds should, between 400mbps up to 900mbps depending on the time of day/load on the network, as you would expect. Now, my download speeds have no variation at all, 7pm on Saturday evening at peak times, 120mpbs, 3am on a Sunday at the quietest time possible, still 120mbps. If speeds were not being throttled there would be a variation to the speeds I could hit. When I do the same speed tests on the Three mobile network when not connected to the home broadband, I get much quicker speeds, as previously mentioned, and I get the expected variation depending on the time of day. As I am about to post this, at 1:15am on a Sunday, I have ran a speed test on the 5G Mobile network and just hit 656mbps download, and then the speed test when connected to my home broadband, 119mbps, five and a half times slower!! Admittedly the upload speed was the opposite way around hitting 30.3mbps on mobile and 63.3mbps on the home broadband, but this again just shows that the speeds are being controlled and throttled. And again, I have attached the screenshot of this test below. 

I would like someone from Three technical support team to respond and finally admit that they are throttling speeds on the home broadband now, may be they are doing this as the network is getting busier as more people have joined over the last 12 months, but they need to admit this and stop the lies.

I took your advice @sc1999 and have looked at other forums, and found the issue with Three clocking peoples speeds at 120mbps download is common and widespread throughout the UK and occurs when settings are changed or a new contact is signed and started. It appears those of us who signed up early had no limitations on the download speed at all and were therefore able to hit these high speeds. But now everyone is slowly but surely being capped to 120mbps. Some interesting feeds and posts on Overclockers Forum below, I have just registered and posted -

Same issues here. Had a new router delivered yesterday - wouldn’t connect to sky or video door bell. Spoke to 3 support who did resets still won’t connect. They are sending a new router now. Plugged my old three router in and now speeds have dropped to 118/120 no matter time of day, 5g phone on the 3 network gets much 400 odd. Prior to calls with 3 the speeds were in the 300s.  Another call to 3 ???

I called them multiple times when it happened to me, and they were completely useless and claimed there was nothing being limited but couldn't explain the huge drop in speeds. They did give me money off my rental though, and eventually agreed I could leave whenever I wanted with no charge. I feel I will eventually be moving back to Virgin, as Three don't seem interested one bit. Fastest 5G network in the UK apparently, limited to 120mbps!

Update on this  -  another 2.5 hours on the phone to support  - got nowhere and speeds 120 all the time which is strange that it doesn’t fluctuate at all.  So, popped off to a three store and picked up a new router and SIM card - new number. Speed test on this 500 then 590! Go figure that.  Now cancelled the old contract and returning the router which was delivered yesterday.  Strange situation!

That's interesting. I got a new router delivered with a new sim but the same number and made no difference. It must be something to do with thr account settings against the number. I will request a new sim card and number if they don't sort themselves then. I just wonder how long will your new speeds last, before they fiddle with the settings and your back to 120? May be they prioritise new connections to get people on board ans to sign up, then limit everyone else's and hope they don't notice. As I mentioned before there will be hundreds or potentially thousands of people where their speed has dropped but they don't notice!

I just want to chime in and say that I signed up for Three 5g broadband last Feb and was getting very good speeds upwards of 800mbps. I'm less than 200 metres from the 5g tower and get a perfect 5g signal, this is the exact reason I signed up for this service. Now I am experiencing exactly the same issues nearly word for word as has been previously posted, and I am now limited to 120mbps max. I have obviously called them and they have reset everything and my speeds will jump back up to what they were for 24 hours and then drop off to 120Mbps again so it is not a network issue and is definitely a deliberate speed limit put in place by Three when in the contract I signed there are zero mentions of a speed limit. Anyone experiencing this, I would urge you to just drop an email or call Ofcom to let them know that Three are not honouring their own contract terms by doing this and trying to blame it on "network issues" when it is clearly not the case. I am in the midlands for reference.

Here are my speedtest results. You can see the times when (07/02/24) I have contacted customer support and had my connection reset, and it jump up to expected speeds for 24 hours then get limited again, this has happened a few times now. Speedtest by Ookla - The Global Broadband Speed Test

I have something really interesting to share with regards to this. As I am with Three for Broadband and mobile, I thought I would do some tests today and swap the sim cards over, and the results are not what I was expecting!

Test 1 -
Broadband Sim Card in Phone - I removed the sim card from the router, and put it into my phone, ran a speed test and guess what, I’m hitting normal speeds with my 5G Broadband Sim in my phone, I ran 2 speed tests, the first at my desk, still hitting 354mbps, and the 2nd I stood at the window where my router is and hit 740mbps download! So, the problem doesn’t appear to be with the sim card itself and there is no limit when using in my phone.

Test 2 -
Phone Sim Card in Router – I removed the Three sim card from my phone and put it into the router to see if the issue is with the router. Speed Tests 576mbps & 617mbps. So, the problem does not appear to be the router directly.

Test 3 -
Broadband Sim back into Router – Now, I was really hoping that things might have just sorted themselves out and gone back to normal after my swapping sim exercise, but I was wrong. Speed test with the Broadband Sim back into the router = 118mbps & 119mbps, back to being limited again.

Mattyk66_1-1708447619462.png

There is clearly something that has been set at Three's end to limit the download speed of the broadband account when the sim card is in the router, but it only limits it when it is in the router!

I have passed all this information on to the moderator who messaged me today to say he is going to help and look into this, so watch this space!

Good stuff, I'm not on three mobile so can't try this myself, unfortunately. I still believe this is a deliberate move to help their network load, nothing else makes sense to me after the conversations I've had with support who after many months still have no answer as to why it's happening other than vague aspersions to some 'hidden' network issues that do not show customer side, and only they can see on their end!?? At worst, they are outright lying to their customers and trying to pull the wool over our eyes (very poorly) or they are just that clueless. I would be very interested to hear what the moderator has to say, but I would be surprised if they can shed any light on it. And I just want to make it clear that they still even now advertise the service as

Truly Unlimited Data

No speed limits. No data caps. Just endless streaming, browsing, and sharing in the UK.

https://www.three.co.uk/broadband

So not only are they in a potential breach of contract, they are also lying in their advertising of the service.

Soooo

The stability of the new routers is also shockingly bad. I am literally watching my router go from a 5 bar signal to having no signal every few mins. I have been having real issues with this since we got out new ZTE MF286D router at the end of Dec 23. I also had to manually change my APN settings and for most people who just want a plug and play internet connection that should t be a thing.
