Replaced router - now download speed has dropped

mikeyb200 — Thu, 31 Oct 2024 17:14:13 GMT

Hi, my TT Sagemcom router died last week, and has been replaced by TT with an identical new one.

With the old router, the download speed I was getting was always above 70Mb/s, sometimes as high as 75Mb/s - using the Ookla speed test. But with the new router, the speed has dropped to no more than 67Mb/s. It's been like this for 5 days now.

Will it eventually return to the previous levels of its own accord, or does TalkTalk need to do something to speed it back up again?

Switch off your router for a good 30 minutes and then on again to refresh the session to the cabinet, this should improve your speed.

Thanks, I'll try that this evening.

Hi sajid, that doesn't seem to have made any difference. Any thoughts on what I should do next?

Hi Chris,

Still got the same problem.

While I was waiting for the engineer to come, I hooked up my old Huawei router. It was happily singing along at 70+ Mb/s. It's just the new Sagemcom that's running slow!

Here's a screengrab of my broadband speed history. You can see the change on the day the router was changed:

OK thanks. Can you please update your community profile to include your:

Name
Telephone number
Alternative contact number

We'll then look into this further. Please do not post this information on this thread. Once you've updated your profile please post in your topic to confirm it's updated.

Thanks

Hi Chris,

OK, done the profile stuff.

OK thanks. Line test is passing and your current sync speed is 70.9Mbps. Which router do you currently have connected?

Hi Chris, I have the new Sagemcom router connected.

By 'sync speed' I presume you mean the speed listed in the router's admin page?

I've seen that reporting 73Mb/s or more, but the actual download speed as tested either using the TT or Ookla speed tests still maxes out at 66-67Mb/s.

I'm not at home so I can't run an actual speed test for you.

Is your router currently connected to your test socket - Your guide to main phone sockets - TalkTalk Help & Support

Hi Chris,

No, it's just in the regular router socket. It's an NTE 5C Mk4 Master Socket, and there's no phone connected at all - and no microfilter either.

Do you have any extension sockets or is that the only telephone socket in your home?

mikeyb200 — Fri, 01 Nov 2024 13:38:36 GMT

It's the only telephone socket in the house. We don't have a landline phone at all, we only use mobiles.

Chris-TalkTalk — Fri, 01 Nov 2024 14:08:12 GMT

OK thanks, are you using the cable provided with the new router?

Re: Replaced router - now download speed has dropped

mikeyb200 — Fri, 01 Nov 2024 15:48:51 GMT

No, I'm not. But the Huawei router was, and it wasn't running slow.

Hi Chris,

Just checked speed this morning. Same old 66.5Mb/s.

@mikeyb200,

If the connection is still in sync at 70.9Mbps, as reported by Chris-TalkTalk yesterday, then that download speed is to be expected. [Download speed is lower than sync speed due to overheads.]

Only if the connection is re-established at a higher sync speed would a higher download speed be possible, hence an earlier suggestion about disconnecting for 30 minutes, which you may already have tried without any improvement.

It may just be that the connection sync speed is lower with the replacement modem/router compared to the previous one. I have seen a difference of about 4Mbps between two modem/routers of the same make/model.

Hi Xplorer, I get what you're saying, but this morning the sync speed is showing as 74.7 Mb/s, and it is generally in that ballpark. So my router throughput at 66.5Mb/s seems rather low to me - don't you agree?

@mikeyb200,

Yes, I would expect the maximum download speed to be around 70Mbps for a sync speed of 74.7Mbps.

Are you conducting the tests with an ethernet connection rather than wireless?

Do the replacement Sagemcom modem/router have the same firmware version as the previous one?
