Well, I've had a home hub for almost a year and thus far - THUS FAR - it's performed reasonably OK. Occasionally (perhaps three or four times in all), when trying to open a web page I get a message from the hub instead, saying something like 'internet not available', but a re-try usually fixes it: once I tried power-off and on again. I put this down to glitches in the broadband connection, not the hub.
What connections between hub and PC are people using? I use the ethernet lead to connect to the desktop PC, in preference to USB - it's faster, but the connectors do need to be handled carefully, admittedly. Anyone whose ethernet lead has broken could always go over to the USB connection as a backup - a lead should have been provided in the box with the hub. I also use the radio connection to the laptop and this works quite well, except when something else in the house is radiating interference (microwave oven?).
[edit] I never tried the phone connection btw.
