Replaced router - now download speed has dropped

[mikeyb200]

Hi, my TT Sagemcom router died last week, and has been replaced  by TT with an identical new one.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

Hi @mikeyb200 

That's great, thank you for letting us know 🙂

Yes please can you return the old router using the pre paid returns bag.

I have sent you a Private Message with a link to a short survey for the Community.

Thanks again.

Hi Michelle and Chris,

Just hooked up the replacement router and run a speed test. Straight off, it came up with 70.35mb/s. 

That's more like it!

I presume I just put the other one in the box and send it back to you?

[mikeyb200]

Hi Michelle,

Yes thanks, it arrived while I was at work today. 

Just about to hook it up...

Hi @Anonymous 

The router Chris sent was for @mikeyb200 

[Michelle-TalkTalk]

Morning,

Just checking back in to see if the replacement router has arrived?

Thanks

Michelle

Thanks 🙂

[mikeyb200]

Will do.

[Chris-TalkTalk]

No problem, please let us know if there's any improvement with the replacement router 🙂

Chris

[mikeyb200]

Many thanks, I appreciate this. 

PS

I should explain - I do a lot of downloading big files in the course of my work, and for me a 10% loss of speed translates directly into 10% more time waiting for my stuff to arrive. As they say, Time Is Money!

I've ordered the router, it should be with you within a couple of working days

Hi Chris,

Thanks for offering. I will take you up on this, as I just can't understand why the replacement router is limiting my download speed in the way it is. Surely an identical replacement should perform identically, and it just isn't.

Cheers,

Mike

Hi mikeyb200,

I can send another router to test with but I think it's unlikely to make any difference. As ferguson says, it's quite normal for different routers with different chipsets to sync at different speeds

Yes, I'm still above the minimum guaranteed. The line stats are good. I've also done the turn-it-off-for-30-mins routine.

As you say, let's see what Monday brings.

[ferguson]

I doubt it will make much difference to be honest. I assume your speeds are above the minimum guaranteed for your line? They could only swap it out for another one of the same model. Have you checked the router stats regarding SNR and so on? Have you been restarting it regularly at all? Let's see what the support team have to say when they pick this up again on Monday. 

[mikeyb200]

I've just borrowed my neighbour's Windoze laptop -  which I mustn't be too rude about as it at least has an ethernet port.

I've run 3 speed tests, and the best of the bunch came in at (drum roll....) 66.8Mb/s

So my interpretation of that is that there's something internal to the router that's  limiting its throughput - agreed?

What do you think my chances are of persuading TT to replace the router again?

[ferguson]

Not "dodgy" at all, I understand where you're coming from. But throw the capabilities of different routers and chipsets into the mix along with the other variables and you are still well within expected tolerances. 

[mikeyb200]

Hi ferguson, I realise I'm on slightly dodgy ground complaining about 'only' 66.5Mb/s - but the facts remain that (a) I was doing 6-8Mb/s better before, with a supposedly identical router, and (b) I could instantly get back to that speed again if I threw the new router away and reinstalled my 10-year-old Huawei!

[ferguson]

Wireless throughput is always likely to be less again, in truth your numbers are really not that bad.

And as a MacBook user myself I long ago purchased an ethernet adapter so that I could connect that way if required for testing purposes.

[mikeyb200]

Sadly since Apple decided MacBook Pros didn't need Ethernet I have no choice but WiFi. 

Regarding the firmware version, I don't know. The old router was just over 2 years old, and had had one firmware upgrade, but I didn't think to make a note of what it was. When it died, I couldn't connect to it at all - its Wifi totally packed up.

I was told by the engineer that the new router did a firmware update almost immediately it connected, and I can see it's now on SG4K100174. It also says it is hardware version FAST5364 3.00.

@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?
