Is it my devices or broadband that's slow?

Hello,

I recently came back to Virgin media broadband and setup new hub 3 on Monday however, I am experiencing similar issues as to why I left a year or two ago with slower than expected WiFi speeds.  I have gone through the standard checks as per FAQ and called the helpline.

There was an issue they resolved but I'm not noticing any difference.

I did a full reset of the router yesterday.

I downloaded the connect app which shows every room of my house has great wifi connection.

Same issue with 2 smartphones and 1 laptop.  I have tried with only one device connected (my smartphone) and only get half of the advertised speed using it.

The laptop was only getting 23Mbps whereas phones are around 50-53Mbps (these are by no means terrible speeds but when I signed up was advised to expect around 100Mbps), I am suspicious there could still be something limiting my account from previous setup which I think was 50Mbps given it doesn't seem to get any higher but it may be that my phone is too low spec etc it is honor 9 lite on Android 9, doesn't support 5Ghz.

 

I tried splitting the networks to have a guest one and use the smart TV on that while my partner used the main one on his laptop but didn't seem to make a difference so am having to not stream video etc while he is using the laptop for work.  The whole reason we came back to Virgin was due to temperamental connection/speeds using mobile phone as a hot spot when trying to work from home during lockdown band being unable to use the laptop and something else at the same time, it is at least a bit better but not much so far!

We've not managed to get the ethernet working on the laptop yet, it's my partners work one so may be down to some security settings as asking for credentials we can't find.  

When I looked for others with similar issues I saw a post asking to copy & paste some details.  I am including these below.

Does anyone has any insight or ideas of what else to try?  Any other useful information I could source?

The cable coming into my house goes into a metal box not the white ones as per the photos online.

I will update with the details of the other smartphone & laptop when my partner has finished work, I know the smartphone is galaxy note 9 edge or something like that but need to check what speed it gets. I'll also try setting up the ethernet cable in case it was user error unable to get it working yesterday so can compare the speeds

Re: Is it my devices or broadband that's slow?

I have hopefully setup the think broadband monitor correctly, I am having issue sharing the link https://www.thinkbroadband.com/broadband/monitoring/quality/share/1d297b0ebcccf3e65c1418080b18a1022a...

If it removes it again the code after share is 1d297b0ebcccf3e65c1418080b18a1022a870525

17.5 Mbps on Samsung Galaxy Note 9 (the laptop was also connected at the same time)

Difficult to tell from the copy/pasted text however:

  • Your downstream power levels are out of spec (-6 to +10 is in spec, 0dB optimal).
  • Your upstream channels (Two of them) are out of spec on QAM (All channels should be 64).

I couldn't get through on the support phone line earlier so will give them a call tomorrow as certainly seems as though there is a fault.

Re: Is it my devices or broadband that's slow?

The wired connection to laptop was even worse! 7.8Mbps at least I have the comparison now for when I call tomorrow and can't try to fob me off with it being my WiFi signal 😄 

It was so bad the speed test link from virgin couldn't even open the adverts

Re: Is it my devices or broadband that's slow?

Engineer visit this morning and in much better shape now, he was surprised we had even managed to get online.  Excellent customer service from retentions & engineer.  Not so much from the helpline when you have a fault with your broadband line.

Still one upstream channel out of spec but going to see how we get on with it over the next few days.
