Broadband speed

[mahutchinson]

Just noticed that my discount period has ended and in May bill went up to around £75 for 200 Mb Broadband, TV and phone. In June it went up again to around £95 and has stayed there. Some of my speeds this year have been 11.46 Mb/s (13 Jan), 21.90 Mb/s (23 Feb), 0.68 Mb/s (21 May), 0.49 Mb/s (20 Jun), 8.39 Mb/s (8 Jul) and 1.71 Mb/s (7 Aug). This is way worse than I was getting on the 100Mb service. I think I've only seen the speed over 100 Mb a couple of times. I just did a test on here and it tells me my hub needs re-setting as it is in modem mode and this could cause issues. I have been using that mode as the wi-fi was so poor using the Virgin router. What issues could be caused by modem mode ? I have read a number of times of people claiming that Virgin deliberately scupper the speed when you use modem mode and re-route your broadband via a slower server.

Modem mode is just fine - been in it for 20 odd years with no issues

Can you check speeds this way
______________________

If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, you cannot rely on wifi tests, - no BB supplier guarantees those - only speeds "TO" the Hub are guaranteed.

So, can you test speeds directly like this. If you expect >100Mbps then connect a 1GB enabled computer/laptop, with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode” (https://www.virginmedia.com/help/virgin-media-hub-modem-mode ). This ensures that NO other devices are connected

Test speeds at https://speedtest.samknows.com/ - try on 2 different browsers as Chrome sometimes gives odd results.

If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.

There are many posts on here (I have a list of ~30!) where QoS software, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.

Report back what that gets. examples why... see message 7 9 in the first thread and 9 in in the second and 3 in the third

Thanks, I'll look at this although my desktop was connected exactly like this until it was moved for re-decorating. Also, regardless of the method of testing the range of speeds and getting speeds of less than 1 Mb/s suggests to me something going other then the method of testing. I also get extreme buffering on TV sometimes so these results are not just from one source.

Lets see the Hub connection data - can you do this
_________________________________________
In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) (DONT click these links) - and hit return. On the first page up dont login (unless you have the Hub4/5 - when you do login) - just click on the “router status” icon/text at bottom-middle (Hub3/4) or top/right (SH’s) of the Login page and then Navigate to these “pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again. If character limits are “exceeded” - just do two posts

If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. Click the lower link (Share Live Graph) then click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

BQM looks fine - no evidence of Network disconnections on there yet

All stats look spot on.

What were the speedtest results after doing it as I suggested in message 2

[mahutchinson]

I tried to connect direct to the hub but couldn't make it work. When I did diagnostics on the ethernet adaptor it said that the IP configuration was invalid. Do I have to put it back in router mode first ?
