See todays Internet connection above - I had a total Internet Dropout from 11:28-11:34 - is this normal? I've had this problem for last 6-8  weeks. As I work home, in the middle of a meeting I go dead and it's a matter of 'earning your living'!! They've now replaced my external cable and given me a new Hub, however the problem is ever present. Internet goes DEAD at the Hub itself as there's no difference with the Ethernet cable too. Even today after getting a new Hub I can still see my old Hub in my Wifi connections - this surprised the Virgin guy who came to replace the cable as it appeared in his Wifi list!! Appears like there's no solution for me?? I

You say ethernet connections are affected too? Have you changed the ethernet cable in case its going faulty (they can!).

What Hub model is it and what do the lights on it do when this happens?

Can you do this so we can look at the connection
__________________________________________

Post up your Hub/network connection details and someone will check to see if there is a problem there.  In your browser’s URL box type in http://192.168.0.1  (or http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before unless you have the New Hub4 when you do] click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages 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.

Also, in the meantime... If you haven’t already, set up a free and secure “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” (as per instructions on the TB website) when it starts to develop.

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired, 2 on WiFi) Hub5 in modem mode with Apple Airport Extreme Router +2 Airport Express's & TP-Link Archer C64 WAP. On Volt 350Mbps, Talk Anytime Phone, x2 Mobile SIM only iPhones.

RIght now I've got 101mbps - I'll need to wait for it to drop off to see the lights. You can see the loss clearly in the link & below...Hub 3.0

I've even invested in a ASUS router but now disconnected as the router doesn't appear to be the issue...

It dropped at ~11.30 - lets see the stats and the logs as requested and we may be able to spot why

Downstream stats look fine!

 

Upstream power looks a tad low!
