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 had the same experience as @Mattyk66  last March I phoned Three about a problem with the router disconnecting, the second level technical advisor, said he had done something to the line (him saying line made me chuckle) which caused my router to be limited to 120mbps ever since, before I used to get 400-500mbps on the router,  on my phone I still get just over 600mbps, it’s can’t be coincidence that after you speak to the tech department you’re forever limited to 120mbps

Out of curiosity can you run your speed test with and without a VPN?

Hi - I don't generally use a VPN. But I have Windscribe installed on my phone, which comes in handy when I'm on holiday, so I just tested and the speed test ran fine, although the speeds were slower than without the VPN as follows -

VPN Active - 83.6mbps download, 59.5mbps upload

VPN Off - 120mbps download, 68.0mbps upload

As per usual, the download speed is bang on 120mbps, but not throttling of the speed of course!

I am going to look into broadband forums and post everywhere I can. I have also messaged one of the Three moderators @JonathanB  on here that others have said has been helpful with their queries or issues so hopefully they get back to me.

One of the tests for throttling is with and without VPN. VPN faster then possible throttling, speeds similar no throttling. Faster without the VPN was not mentioned.

I ran a few more speeds tests picking different VPN locations, and when using a London VPN, the speeds were slower, but when using anywhere else, the speeds were almost identical -

If this is not speed throttling, what else could it be. The moment Three changed settings their end I am stuck on 120mbps? Could it be a firmware update to the router which is limiting the speeds?

There are a few cases where people have questioned whether 3, Vodafone and EE are throttling ang the consensus is no. They give a range of plausible suggestions as to why drops in speeds happen. I still say that 3 cannot increase capacity fast enough to maintain the initial high speeds which is why they aim for 150meg. Bandwidth is not infinite and people are just beginning to realise it. PeteG posted that 3 do not throttle.

3 use the usual weasel words in their contracts and don't appear to offer any minimum guaranteed speed. This is what they say:

Advertised 5G Home Broadband Speed Claim –The advertised 5G download speed of 150Mbps applies to at least 50% of 5G Broadband customers between the peak hours of 8pm and 10pm. We measure the speeds delivered by our 5G Radio Access Network to customers across our 5G Network and calculate the average (median) 5G data throughput rate at peak hours on a daily basis. In Dec 23 - Jan 24 the median figure was well above 150 Mbps each day and we continue to monitor this on an ongoing basis. Due to the nature of the wireless technology delivering your Broadband, the speed that any individual premises will experience is not guaranteed, may vary and can be impacted by local factors, such as the positioning of the hub, line of sight to your nearest mast, local topography (such as hills), number of users accessing the network in your area and thickness of walls and windows.

If you then read the contract there is no mention of performance other than to refer you back to the above statement.

In the old days unlimited did not mean unlimited. If the provider thought you were using too much data they would limit your speed. If it was widespread now I would have expected to see more complaints in the media.

PS. This it not the best place to post this as there is very little traffic as you can see by the number of people who read your post and even fewer who reply. I would try posting on a broader consumer based forum/website to see if it is a widespread issue.
