Slow 5G since few days

mbedna123 — Thu, 24 Apr 2025 22:35:09 GMT

Around 2-3 days ago my latency has experienced spikes while playing games, usually i get around 20-30ms, now its 25-600ms with spikes.

I live around W3 in London, i have tried everything, checking my Lan cable, resetting my hub and network status.

Hi @mbedna123,

Sorry to hear that you've been experiencing lag recently. Did the Network Status checker show that we're aware of any local issues? I appreciate it doesn't solve the issue, but can help indicate what sort of issue we're dealing with. Are the issues persistent on your wired connection and when using Wi-Fi?

Thanks,
Jonathan

Status checker showed nothing, I'm used to seeing some engineering work being done few times a year but now it shows nothing. The main problem is that the ethernet and WIFI works fine, I can download apps and other things, however when I try to play games or talk online I have very high latency,ping,ms the games run very poorly, stuttering and lag. It never happened before. I have updated my contract today (25/04/25) for a new 5G router and same plan, nothing has changed. What should I do ? The Three Broadband app tells me I have "excellent" signal strength.

That's strange. What speeds are you getting on the downloads that are working? It might be worth doing a network speed test, and also checking the packet loss% to see if there's any signs of issues there.

600-900Mps on Download, 50-90Mbps Upload

What about the data packet loss?

Hey, im having the same issue, specifically seeing latency spikes on applications like discord or dns requests for sites. Just replying to see if a mod could assist. 🙂

Also you should try google's public dns in replacement, seems to drop the latency by a bit.

Hi Pete,

Im having the exact same problem too. High speeds, low ping, 0% packet loss. The Internet is working perfectly but as soon as I try to play a game online its constant lag and latency spikes. Im baffled. Been for abkut a week now and previously worked with no issues and no changes to cause this issue.

Hi @Jawaad,

We've seen a few posts about latency and ping issues recently, so I've flagged the feedback in case there is some sort of network issue. Are you getting good speeds, but disproportionately high ping?

It may not be suitable for your networking set up, but one community member has mentioned changing their APN from 3internet to three.co.uk here:

three.co.uk is the mobile data APN, so it uses CG NAT, and won't support some features like port forwarding, but may help depending on your set up, and may point to whether it's a similar issue.

Thanks,
Jonathan

Hi @mbedna123, @Joe_W89,

I've linked a thread above that could possibly be linked, and the OP mentioned a workaround that may help.

Thanks,
Jonathan

I have been having this Issue as well for nearly 2 weeks now. download and upload speed has not changed but my latency goes from 30ms-500ms. Been using the internet service for 2 years with no issues until now.

Switching apn from 3internet to three.co.uk solved it for me, was experiencing this exact problem - Three needs to look into it

In Leeds area and having exact same issue. Normald download speeds remain but have had very high ping (300+) for the last week and a half making games unplayable. Changing the APN made no difference for me. Hoping this is fixed soon.

Hi @Venny,

Thanks for reporting this, we've had a few confirmations that the three.co.uk APN is a workaround from similar reports. Just in case this isn't a related issue have you checked the Network Status Checker? This may help determine if there's a local mast fault.

Thanks,
Jonathan

In Manchester area and also having this issue. The Network status checker is saying there is working going on in the area, however I am fairly certain this issue started before it said this? Is there any way to get more detail on the work being done? Area is M32 ***.

Hi @Gorrie59282,

Sorry to hear you've been experiencing similar issues. It's best not to share your full postcode in a public forum. Customer services may be able to share a little more insight on a network problem, but generally they can't say much more than when it started, and an estimate on when we're hoping to have the issue resolved.

Please let us know if the engineering work clears this up for you in the next few days, I'm continuing to pass feedback along about this issue.

Thanks,
Jonathan
