Smart Hub 2 - internet connection painfully slow today

Go to solution

Hello,

Received a Smart Hub 2 in July 2020 and it has worked great until today. Internet is painfully slow and will time-out before some pages load. YouTube videos are buffering, but not all the time. Occasionally it will work fine for a few minutes then fail to load.

I turned off the Hub and disconnected the power. Still having problems although the blue light is constantly showing. 

Several devices are connected over WiFi and the PC is connected via a cable to the Hub.

Any help, suggestions or advice appreciated.

welcome to the BT community forum where customers help customers and only BT employees are the forum mods

in order for the forum members to help please can you post the stats from your router (if hub enter 192.168.1.254 in your browser SH2 then advanced settings then technical log information . 

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

 

enter your phone number and post results  remember to delete number   https://www.broadbandchecker.btwholesale.com/#/ADSL

Your stats look ok with actual connection just below attainable. Short connection time I assume was the manual reset you mention.

You are obviously uploading large amounts of data compared to download and that would cause slow reaction time.

You are on a Huawei cab and if you can maintain a stable connection then DLM will improve speed withG.INP  but you need to maintain a stable connection for a few weeks first

Thanks for your reply. I'm not very technical so might need someone to elaborate on a few bits:

You are obviously uploading large amounts of data compared to download and that would cause slow reaction time.

Not doing anything different today than usual. We are a family of four; kids play games on their tablets, we watch TV via a smart stick, use PC for work.

You are on a Huawei cab and if you can maintain a stable connection then DLM will improve speed withG.INP  but you need to maintain a stable connection for a few weeks first

Please can you explain; cab, DLM, G.INP

Just tried to load YouTube and got this:

Thank you for providing an explanation.

Sadly our internet connection is still not right - I had to reload the page several times to be able to post a reply...

As already stated , something looks odd on your upload ( especially if you don’t knowingly upload large amounts of data, like uploading video etc. ) , in the approximate 5 hours the router stats show, you uploaded 11 times more data than you downloaded , over 56Gb .
With most regular domestic broadband usage , download is greater than upload, watching video, downloading games , etc  …in part that’s why most ‘broadband ’ is asymmetrical , the download bandwidth greater than the upload as that’s where the need is greater, your usage is in effect backwards ….something may well be saturating your upload and it’s having a detrimental affect on your download…you could try isolating various devices to see which is causing that, basically connect one device at a time , and check performance.
AFAIK , malicious software can hijack your connection and in effect use your connection for nefarious purposes, so you may have an infected device ‘using’ your bandwidth .

This is often cause by Peer To Peer software running, like Bit Torrent.

Go into the hub settings and disable UPnP, then restart the home hub. That will disconnect and disable any unauthorised uploading. If the speed improves, then you need to identify the device which is running that software.

Uploading to cloud services like BT Cloud, can also slow things down.

Any excess uploading will slow downloads, as it prevents acknowledgement being sent for received packets.
