following reboot the speedtest still showing approx 20Mbps ... however upon getting up this morning and testing it has shown me 30-35 Mbps...
The Xirrus monitor is showing both local VM wifis registering approx 60 dbm (as it was last night).
I am going to attempt to remove all adapters again and reinstall the necessary ones, I'm a little unsure why my USB LAN card is showing as Ralink as I'm sure that was the old one (?), and I'm unsure precisely what the IntelR network connection is.
Thank you again for advice :-)
