Hi,
Sorry for late reply and thanks for replies
Ports: Have swapped ports - no effect
Client: Win7
Age: New installs
Browser: Firefox / Chrome/ IE
Test servers: All of em
Long story short i rang VM tech support. They tested everything, no faults found. Connected remotely to one of the 'slow' PCs. Played with drivers and duplex settings as i have done many times. Reset SHub to factory settings (for the 99th time). No change.
They are sending out new SHub within 2 - 3 working days.
We were going to bite the bullet and buy an Asus RT-A68U router, but are going to hang fire.
Will report back when new SHub arrives.
