I've had this issue for a couple of weeks on and off. I can be working on my laptop and suddenly it disconnects and states "connected, no internet". This happens on various devices at various times but other devices will still be online and able to access the internet. It doesn't just affect my laptop. This morning I had Wi-Fi on my iPad, opened my computer and couldn't connect, my son's laptops could not connect, my phone could not connect, but my other son was working on his laptop fine and all connected.
If we are lucky a hub reboot will fix it, or will let some devices on and kick others off.
We upgraded to the Hub 5 which we installed yesterday, hoping it would fix the issue (and improve speeds). It worked perfect yesterday until my sons came home and then would not let them connect any devices to the wifi. Turned the Hub off twice and eventually it let us all connect.
I've phoned Virgin 3 or 4 times to be told its a 24 hour stability issue, or its congestion in my area but I don't see how it could be when some devices are fine and others are not. I don't know much about Wifi/broadband but it seems to me that the Hub is preventing devices from connecting. I just don't know why.
Has anyone got any idea what's going on and how I can fix it?
