hi there. after what i think is a total fluke, my sure signal box is working. i got infinity on monday and sure signal today. set sure signal up as pr instructions, and nothing. after reading the internet i turned off my new hubs firewall, and set vpn to port clapping and still no bars. thought that i would have to downgrade infinity back to normal broadband as my phone is my working life. while on the phone to bt to downgrade, it came on, about 3 hours after i have set it all up. when i spoke to vodafone, they said that it wouldn't work, the fact that infinity is pppoe and not pppoa being the problem. anyway, baffled, but its on and working. currently enjoying full five bars on an iphone 4, with 3g and everything.
