Slow Broadband in the evenings

Highlighted
2: Seeker

Hello,

 

I’ve been finding I’m getting quite slow broadband speeds in the evening more recently, I’ve tried the usual but haven’t yet called Vodafone support as I’m using my own router - and I’m anticipating the need to revert back to my Vodafone router to get any meaningful analysis.

 

However I’ve been reading through the forums about how the symptom of slow broadband just in the evenings is often an over subscription issue (I appreciate it’s impossible to say 100% until tests are performed).  The blame seems often to be put towards BT Openreach, however often the forum posts speak of fewer problems on providers such as BT.

 

I had assumed that this over subscription was in relation to the local exchange and so wondered how changing Broadband providers would help the situation.  My initial opinion was that the cheaper price of Vodafone Broadband is attracting many customers and so it’s becoming a little saturated but wondered if that’s even possible - or if it’s more a case of just a saturated exchange.  But would be good if someone could help explain.

 

To add a little more context, I live on a relatively new estate (3 years old) with new houses being built nearby, so could appreciate the local exchange gradually having an increased number of total subscribers regardless of their ISP.  Oh and I work in IT, so do to keep an eye on my network performance / troublesome devices / WiFi connections.

 

Thanks

Rob

If you call Vodafone's tech support they will require you to use their router in order that they can attempt to diagnose any fault(s).

 

The systems fault that appeared around November last year is now (mostly) fixed, but there are always going to be users that experience faults.  In the case of new build estates, those faults can be more common, and as more lines get used in the cabinet you can get more cross talk and so speeds drop.

Thanks for the reply @KeithAlger, but I’m not sure that really answers my questions - although maybe the point about cross talk may?

 

In my original post, I tried to highlight the fact that I haven’t called Vodafone, along with the reason.  I’m also not using this post as a means to get my issue fixed, I’m simply trying to understand how the over subscription works in relation to other forum posts as per my original post.

 

I appreciate the response, but would be good to understand as per original post.

 

*EDIT* Just realised I didn’t actually put a question into my original post so just added that in - apologies @KeithAlger

 

Thanks

Rob

The problem is jumping to the conclusion that the problem is oversubscription!  Vodafone piggybacks on the Openreach network in at least two different ways.

For most of us, our connection over the Openreach network stretches from the cabinet to the BT exchange.  At the BT exchange, we are connected to the ex-C&W DSLGB network which feeds back to VF's regional data centers.  It is the case that there may be exchanges where the DSLGB link to VFs datacentres doesn't have the capacity and you'd get slow-downs as a result, at least until more capacity is brought online!

The other common connection route is where there is no VF equipment at the local exchange and the data remains within the BT Openreach for more of the route to a regional VF datacentre.  Generally these experience less congestion, but due to the higher costs involved in using someone else's network, they are not going to be VF's first choice!

I guess the big question is how much of a slow down are you seeing, and how are you measuring this?

Thanks for that, helps make a bit more sense.

 

The speed has gone from around 28-32Mbps during the day to around 6-10Mbps from around 7pm until 10pm, although as I type right now it’s still gradually increasing back, currently at 10-18Mbps (11pm).

 

I’ve been testing the difference between single/multi connections and there’s a little difference but nothing too major. Both fall within the limits I mentioned above.  I’m also getting similar speeds via VPN.

 

I’ve measured using a few different speed test services, Google (M-Lab), Speedtest.net, SamKnows and BT Wholesale. Although less scientific, it’s also very noticeable with general tablet / PC usage.

 

So from what I understand from your response, the point around over saturation being any better when changing ISP’s all depends on whether there’s Vodafone equipment in my local exchange. Appreciate I’m perhaps over simplifying it a bit, but is that about right?

Hey @Daint, I'm sorry to hear you're getting slower speeds than you expected and know how frustrating this can be. 

As you already mentioned, you'll need to have your Vodafone router connected for us to run diagnostics. If you'd like to do this and have one of our team take a closer look into your speeds for you, I've sent you a private message with details on how to get in touch.

yes facing the same issue too.

Just as an add on to what's already been posted, there are various sites that allow you to see which ISPs have their equipment installed in the local exchange.

So you can do this using https://availability.samknows.com/broadband/exchange_search though other sites are available!

It's disappointing to hear you're having the same speed issues @Adrianosaunder - I've also popped you a private message over, so you can contact us directly too.

As I'm probably more in favour of just moving to another ISP when my contract is up rather than the hassle of ISP router and the internal DNS changes that I'll have to make - I wondered @Adrianosaunder what had come of your issue?

You might be a better judge of these are my evening speeds...

My Broadband Speed Test - Avg Down: 0.9 Mbps, Avg Up: 0.4 Mbps (via @thinkbroadband) http://tbb.st/1557007322604039255

 

I am still trying to get my head around the speed guarantee scheme?? I am on Superfast Broadband 2 package!!!

@wolves2005 not only are those speeds appalling but ideally, the graph should be relatively smooth.  It kinda suggests there is either a line fault, a major source of radio interference, or that you have a faulty router.  If you've not posted this already, it'd be interesting to see your sync speed too (from the router web admin pages).

Speed test results 06.05.19.png  @KeithAlger - Thanks Keith. You are right about the appalling speeds. These are results for test run done just now. I received a call today from the Vodafone Customer Care team in response to my written complaint. The person agreed that the speeds were quite low and have assured that the technical team is going to look into resolving the issue as early as possible. Fingers Crossed!
