Hi, my package is with volt 1 gig but I'm only getting 300mb/s

My broadband speed has dropped to 300 - 500 Mb/s, was OK, can you please fix it? Thanks

    Share a screen shot of the Speed to the VM Hub and at your device...

    https://www.samknows.com/realspeed/

    ( also very handy is the Samknows Realspeed app for Android & iPhone )

    Once the test begins click on: Run full test to include: Latency, Jitter, Packet loss & Upload speed

    The speed at the Hub should reflect your subscription.

  • Thanks for the replies

    Hub is in modem mode, will it work in modem mode, also any idea if their white box can be used with the hub in modem mode? Desktop is connected by ethernet to my router, which is connected via ethernet to my hub. I'm sure I was getting over 900Mb/s before this recent check.

    Thanks

      Will not work in modem mode. Drop the hub back to router mode, run real speed, and then return to modem mode. Also post some stats.

      How to get stats from a VM hub (no need to logon to the hub)

      Open a web browser and go to 192.168.0.1 router mode or 192.168.100.1 modem mode

      • Click on the “> Check router status” button
      • Click on the “Downstream” tab, copy the text and paste into your reply, do not take a screen shot
      • Click on the “Upstream” tab, copy the text and paste into your reply
      • Click on the “Networking” tab, copy the text and paste into your reply.
        • Do NOT post photos or screen shots they will be rejected as they contain MAC addresses. The board software will automatically change MAC addresses to **:** if done as above.
  • Hi Tudor

    I connected my desktop directly to the hub, which I switched to router mode. Samknows couldn't find it. So did a standard speed test, got 950Mb/s, so looks OK. The info you requested is pasted below. Switching back to modem mode and trying again later! Thanks for your help, though I'd be interested in what you think re the info below.

    Have to paste info one at a time, character count exceeded!

      Those downstream stats show some channels are too low and it is backed up by the error counts. You definitely need a technician’s visit to rectify. Phone it in as a fault. 

      The primary place to report faults or for service requests is Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post. This board is not a fault reporting system.
