I'm not familiar with the Super Hub, and frankly, very jealous of the speeds Virgin offers!
I had to look up some info about the super hub and had some questions that might clarify the situation:
When you have the SH in router mode, the ethernet cable coming from the SH connects to which port on the Almond+? While intuitively, the incoming internet connection should connect to the WAN port on the A+, try connecting it to one of the LAN ports and run the test again (and another LAN connection going to the computer)
Keep in mind the following:
- This SH-to-LAN port setup isn't optimal when the SH is in modem mode.
- The A+ may not correctly report that it is online, even though it obviously is.
I've been reading reports on another topic that the A+ using firmware R065 may be introducing garbled packets when crossing from WAN to LAN. It may explain why you're seeing faster wifi speeds compared to your current wired connection.
