Internet speed

Speed changing after reboot.

  • Strange one.  I'm paying for Superfast 2, 55mb.   Been slow since September after a power cut (was getting 70mb but dropped to mid 30s).   Last Friday about 3am my router rebooted and suddenly syncing at 80mb and getting 75mb on Speedtest.  Been constantly high since then......until today.  Had a new smart meter fitted and turned off the router as the electricity was being switched off.  Turned it back on and back to 35mb again.

 

The dsl Status says 

 

Current rate 36,036

Maximum rate 80,455

 

The maximum rate has been that high since September, but until last week I was stuck in mid 30s sync speed.

Hi @NewtonBoy, do you know what your minimum guaranteed speed is for the service? Since posting the message a couple of days ago, have you seen any improvement with the sync speed?

I think it's 33.4.  Current sync speed is 31.2.   But our village was upgraded after I signed up with Vodafone.

 

My neighbour is with you too.  He gets a fast speed and I've even tried his wifi from my house and get twice the speed I'm getting!

 

The current line quality stats on my router in the DSL Status are:-

 

Current rate 31189 kbps Maximum rate 73947  SNR 23.8db

The router is obviously having trouble negotiating a stable speed with the cabinet, the SNR should be around 6db.

Have you tried with the router connected to the test socket?

Yes.  I had it connected to the test socket for months (I've spent hours and hours on the phone to tech support,  so I didn't bother removing it).   But when Openreach came in September they put a new master socket in which doesn't have a socket for the phone when the test socket is used. 

 

I'll try it tomorrow (I need to move a cupboard).  Should I just remove the phone lead and switch sockets or turn off the router and reboot?

 

When I had my 80mb sync speed last week my SNR was IIRC 5.6db.

You will need to use a plug-in filter, however if Openreach have just fitted the new socket they will have ensured that problems such as those caused by internal wiring have been eliminated. If you have the latest filtered socket you remove the front panel by squeezing the sides, no tools required.

If you try to plug the router into the phone connection of a filtered socket (the one with separate phone and internet connections) it wont work at all, it will be already filtered.

I would power off and back on, but to be honest either should work.

Your line appears to be much like mine. If I reboot I get a sync of approx 79Mbs with an SNR of 6.3db, but after a few days DLM seems to cause my router to reboot, at about 2am, and it changes to 80 at 5.5. Why yours starts so low is a puzzle. It's worth trying the test socket again, but from what you say it doesn't sound likely to make much difference. If does improve things then maybe the (new) filtered faceplate is faulty.

Incidentally, I did an online chat yesterday and was told to change the DNS settings to 1111 and 1001 and everything will be good in 24 hours.  Would that affect my sync speed.  24 hours later, nothing's changed.

I'm afraid that DNS settings are not related to Sync Speed.

Try this link https://www.broadbandchecker.btwholesale.com/#/ADSL and it should tell you a number of things including the expected max and min speeds. The Sync Speed is an indication of the line capacity and is not the same as the experienced download rate which depends on a number of things.

I totally despair at the things Vodafone tells customers. A change of DNS in the router will take effect immediately, but will have no effect on sync speed.

That website gives me:-

Range A (clean) high  61.4  low 42.9

Range B (impacted) high 60 low 40

 

Last tested Jan 4.  

 

Should my guaranteed minimum speed be so much lower than the low figure?

Guaranteed minimum speed is a pretty meaningless figure, but it should be no lower than the Handback
Threshold shown on the webpage @cynric posted.

You can see what Vodafone think you should get here:

https://www.vodafone.co.uk/broadband/deals/superfast

You line is capable of much more, your SNR figure proves that. You may need Openreach out again to do more checks. They seem to dig a little deeper on the second visit.

Have you tried in the test socket? Vodafone will probably not take it any further unless you have been connected in there for 72 hours.

The Vodafone website says I should get 63mb on Superfast 2.

 

Can't use the test socket and the landline simultaneously with the new master socket that Openreach fitted in September.   

 

I had the problem in December when I tried again to get this sorted. The tech team told me to plug the router into the test socket and they'd phone me to talk through it.  When I plugged it in I realised that I couldn't use the landline.  

 

Unfortunately,  we don't get a mobile signal indoors!

Yes you can, you use the plug-in filter that was supplied with the router.

Silly me!   Done that.

 

Figures immediately after connecting to test socket with splitter.  Current 44,501 Max 45xxx SNR 3.6.

 

Five minutes after reboot,  Current 44,501 Max 88xxx SNR 18.6.

Your rapid changes of SNR looks just like the problem I had and mine turned out to be a faulty fibre port in, I believe, the cabinet. Openreach swapped me to another port and all has been good since.

Obviously yours may not be the same cause and Vodafone tried a replacement router first before calling out Openreach for a second time.

The only trouble you will have is convincing Vodafone to do anything. I would not bother with chat or social media but call them direct on the broadband support line 08080 034 515. It will still be a hard process but you will have more chance of a resolution.

I'll ring them tomorrow.   They sent a new router after the first Openreach visit, which made no difference.   

At least I'm getting a fairly decent speed after using the test socket, but it's costing Vodafone a 15% discount every month.  

 

I had a very terse phone call in December saying I was getting Guaranteed Minimum Speed so I should stop complaining.   

 

Only 17 months of my contract left!

 

Thanks for your time and help.  Much appreciated.   I wish I had the same service from Vodafone.

The trouble with a varying SNR is if it reaches O the router will reboot. I was getting sometimes 4 or 5 a day, possibly that many in an hour, other times it might go a week without rebooting but during that time it would be running at a much reduced speed and still with varying SNR. It took all told 3 months from joining Vodafone to getting a stable line, and it was hell.

Good Luck.
