I am usually the first one to criticise VM's customer support but Stephen does have a point. You should also be aware that whilst there are many tech savvy peeps on this forum, it is in no way affiliated with VM and they won't read your post or respond to it. If you want them to take a look at your problem then you need to make a post on the official VM support forums
here.
That being said, if you would like to post your power levels etc we'll take a look and point you in the right direction so you understand what is going on. Click this
link and scroll down to the fifth post and you'll see what we want. You'll probably need to go to
http://192.168.0.1 instead of
http://192.168.100.1 as instructed in the post.
While you are at it, can you also provide additional info as to whether your connection to the shub is solely wireless, what device you are using (e.g Galaxy tablet or Dell laptop), the make and model and which OS it is running.
