Hey everyone, 

Apologies if this has been posted before - I have spent hours scouring through google searches etc. Up until today my router has been fine. Today my wifi speed has dropped to under 1mbps if I'm lucky. Connecting via Ethernet is fine, and disconnecting the C50 and connecting the PC to the Virgin Media Hub 3 directly shows that the VM speed is fine. I've upgraded the firmware on my router, and then the internet LED on the router changed to orange for a while. I disconnected the coxial from the hub and internet is back through cable and wifi but the wifi is back to being incredibly slow. The LED is back to normal at least. 

Before today nothing changed in terms of hardware, the speed just plummeted. Any ideas what else I can do?
