Slow with latency issues: 200Mb in NW6

I recently upgraded to the 200Mb service and Hub 3.0 and thing seem to be slower. I'm running the Hub in modem mode. Even on a wired connection, I can experience buffering on Youtube (seems to be quite common on Virgin from what I've read) and occasional issues with Netflix and Amazon Video. Latency can be a real issue, with browsers waiting some time before loading the webpage. Surprisingly downloads can be quite speedy although not significantly better than my previous 100Mb connection. 

Router status is below. Any help would be appreciated!

Re: Slow with latency issues: 200Mb in NW6

SNR is too low. Forum staff are taking up to 2 weeks to reply at the moment, probably best to phone in. Early morning is best to avoid off shore and to speak to someone who has a clue.

Re: Slow with latency issues: 200Mb in NW6

any help from Customer service would be appreciated.

Main issues are time waiting for websites to load, ping times and slow speed test results.

Thanks

Re: Slow with latency issues: 200Mb in NW6

Hi browncoat

 

Thanks for posting back on the community.

 

My apologies that you are experiencing issues with your broadband connection.

 

As HiVMBye mentioned the Modem SNR (signal to noise ratio) is running low and I can arrange an engineer appointment for you, to check this over. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please. Once you have replied I can go ahead with the appointment.

 

Hope to hear from you soon

Sam

Re: Slow with latency issues: 200Mb in NW6

Too many concurrent users online in NW6, especially on Saturday & Sunday.  The local cable network needs a massive upgrade.  I am typing this using my neighbour's free BT WiFi hotspot.  Maybe time to find better broadband provider...

Re: Slow with latency issues: 200Mb in NW6

Further to my previous reply just to update that minutes after posting it, surprise surprise, my broadband leapt into life on both wired and wireless after being continuously down or slow for about 6 hours today. Seems that perhaps someone reads my post and then flicks a switch somewhere...!

Re: Slow with latency issues: 200Mb in NW6

Quick update:

An engineer visited and confirmed there were no SNR issues. He replaced the Hub 3.0. On router mode it seemed fine but on switching to modem mode everything started crawling again. I spoke to 150 and they recommended a Hub 2+ (2ac) router. Modem mode remained slow. I have since switched the router back to router mode and initially speed was excellent. 

Tonight download <10Mbs with stuttering iplayer. I think a new broadband provider maybe required....
