Reply With QuoteHave you checked the service issues page on BT?
Since, Thursday evening I have had an issues with some websites not loading bbc, hotmail and pistonheads for example. This website took too long to respond.
TZ and home.bt.com loads OK.
E-mails are slow to appear on tablet.
Tried on multiple devices iPad, android phone, desktop and laptop running Windows 7. Tried phone and tablet at work and works fine.
Can run Speedtest app on iPad and get good results Ping 8 ms, Jitter 0.76 ms, Upload 72 Mbs, Download 19 Mbs. However, cannot access speedtest and BT speed test check websites.
I have restarted BT hub 5, reset it. Changed to a brand new Hub 6 with new filter. In Hub manager status I connected and light is blue on the router.
Tried Safari and Chrome on iPad and Firefox and Opera on PC.
Sky Box does not download and can't stream via Amazon Firestick.
BBC app slow to update and photos not always displayed on news story.
Inserted into BT test socket.
Have tried with Ethernet cable from router to laptop same issues. Changed to Google and Open DNS no change.
Called BT and they run various test, but can't find any problem. Suggestion, was to book an engineer, which may result in a charge.
Any ideas and what to try next?
Thanks
Have you checked the service issues page on BT?
All Ok. Also called BT, they can,t see any issues.Originally Posted by Chalet
I doubt it is malware, because it is affecting multiple devices including sky box and fire stick. Also, tried on a computer that I have have not used for months and had the same issue.
If you lived local, I'd pop round with my network analyser and have a look. And drink your beer.

The fact you can't ping www.bbc.co.uk by name looks like some DNS issue. I'll have a check on my router as I have BT Infinity too. Once I've got out of bed. It is Christmas after all!

No Rush.
Going to Church and then to mu Mum's will be back latter on tonight.
are you on windows ??
Try - RUN CMD ipconfig /displaydns
then
ipconfig /flushdns
I do this periodically. Sometimes BT do switching when doing maintenance -- I fiond that this helps.

Thanks
Running Windows, Android and iOS.
Tried the ipconfig commands. No success.
BT Engineer booked, because the issue remains and they can't see any issues after doing some further testing.
I'd be astonished if it was anything to do with the line.
It does have all the hallmarks of a DNS issue. At the risk of asking a silly question, do you have DNS settings on your router that might be worth changing?
It's difficult to diagnose remotely. The OP mentioned that he had swapped hubs so unless he had manually changed DNS on both hubs, at least one should be automatically set to the correct address. In my experience with work, Openreach engineers are great at fixing physical issues (at least they are in my local area) but not so hot with internet routing etc. Could be a job for Teamviewer and coffee.
Can't change the DNS on a BT router, as far as I am aware. However, I have changed the DNS (Google and Open DNS) on a few devices with no success. It appears most websites just time and a few other are OK. There is a lag before e-mails arrive on my ipad.
If you log in with your admin account you can configure all of your settings on a BT router in the Advanced Settings tab. The password is on the card at the rear of the device.
Did you check the BT DNS helper yet?
No, what is it?
Thanks
This is almost definitely DNS related. When you say you're changing your DNS, where are you making the change? At router or adapter level?
On some of the individual devices.
Not sure how to do on the Hub. Have gone to Advance Settings on BT Smart Hub Manager and then IPv4 configuration. What do I do next? See attached JPG file.
Which model is the hub? Ie hub 3, hub 5, business hub? I couldn't tell you how off the top of my head but if you Google "change DNS home hub 3" it should give you the result you need.

It's hub 6 the smart hub. The limited search results that I can see suggest it. To possible to change the DNS on hub 6?
What happens if you type "http://212.58.244.56/" into your web browser? Does the BBC News site come up? is it any different to when you type "http://www.bbc.co.uk/news"?
If you open a Command Window ("<Win>-R" and then "cmd") and type "ipconfig / flushdns", can you then access the problematic web sites?
http://preferences.webaddresshelp.bt.com/selfcare/
BBC News does appear however, it is slow to load and photos are not displayed. If I use http://www.bbc.co.uk/news photos are displayed. But, when I click on Health section photos are not displayed and when I refresh the site does not load.
Did the flush command. Tried some other websites and receive the message "This site can’t be reached"

Using the following DNS on the wireless connection for the PC.
Preferred: 8.8.8.
Alternate: 192.168.1.254
Hmm - like others, i had also thought that it sounded very much like a DNS issue. But if you are getting equally slow loading when you use the IP address, then that would tend to rule out DNS.
I assume you mean 8.8.8.8 as your primary DNS server. It might be worth also trying 9.9.9.9.
What's 192.168.1.254? Is this the (LAN) address of your router (It's a non-routable address, so it will be something local to you, and this address might be the cause of your problems). I would try removing it (you only need a second DNS address as a backup in case the primary one is unavailable, but normally both would be external - personally, I use 9.9.9.9 and 8.8.8.8).
Also, in a command window could you try both "tracert www.avforums.com" and "tracert 176.56.60.158"? The results might help show where the issue is.

I believe 192.168.1.254, is the DNS on the BT Hub.
Have changed Primary and Secondary DNS to 9.9.9.9 and 8.8.8.8 on the wireless connection on my desktop.

Update, the BT Engineer has come and can't find any issues with the line. This type issue has occurred in the past with the solution being to cease the line and then reinstate it.
Hopefully, that will work?
Does he mean reset the line? It sounds like there is an issue between your hub and the local DP, especially since the engineer has referred to it. It will affect the line speed, possibly taking you back to the days of 28.8K modems.
Did you ever get to the bottom of this?
No, apart from the engineer have seen this only once before and the only solution was to cease the line. So waiting for BT to reconnect my broadband , after doing a cease on it.
I assume that you have done a clean up with CCleaner or something of the like.
I have a BT homehub 6 - Have you changed any homehub settings I'm thinking firewall etc ?
