Wifi blackspot is probably a separate issue from the poor connection. You can either phone in and take your chances with VM's famous telephone support. or you can follow the instructions below and we can take a look for you:
Connect to the hub by clicking on this link http://192.168.0.1/ That should pull up the log in page for the hub. But don't log in, just click on the link "Check router status" That'll bring up a window with five tabs. Open the Downstream tab. Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as text not screenshots. Post that, do the same for the Upstream and Network log. You'll get an error message when you post the Network log, just click on "post" a second time. If the hub was a self install, you may be required to select language and log in the first time you connect. Then we can check for any obvious problems with power, noise or error counts.
Then, setup a BQM over at https://www.thinkbroadband.com/broadband/monitoring/quality that'll show what's going on with your VM connection. Post a link to a live, shared graph here and we'll see what's happening. Usually needs to run for 24 hours before we can draw reasonable conclusions, but the live graph will continuously update so you can do that immediately.
