I have just made the switch from BT FTTC to 100MB Virgin. The install went smoothly, however the wireless range on the Superhub is noticeably poorer than the BT Home Hub. Admittedly the hub is in a different location to my previous Home Hub, but I would still expect wireless coverage in my typical 3 bed semi.
Would people recommend running it in modem mode with a different router or would a wireless access point be a simpler fix?
The Superhub is well known for it's useless wireless. If the distinctly low budget routing capabilities meet your needs that there is no need to splash out on a new router and run it in modem mode as a TP-Link wireless extender should fix that at lower cost than a full blown router. If you need a decent router though then modem mode is the way to go.
The Home Hub had good coverage, but I did suffer from wireless dropouts regularly. I am not sure whether this was the internet connection dropping or the wireless itself - I think it was the wifi as I wouldnt be able to connect to the wireless during the drops.
I may try this again, but have a feeling I may have the same issues, albeit with better wireless coverage
