faster internet and new router - advice needed.

Hi guys, need help in upgrading my internets.

Currently with Slingshot on ADSL with an old Linksys WAG200G modem/router. Getting 13.5Mb/s down and 0.5Mb/s up. Needing faster up speed for uploading to youtube.

VDSL and fibre is available on my street. However I am four houses off the street and have a shared driveway which is all concrete with no grass verge.

Although I'd like fibre, getting permission from my neighbours is going to be difficult so am leaning towards VDSL.

My questions:

1) does this router support VDSL? - D-link DSL2880AL

2) does this router support fibre? - D-link DSL-2877AL

3) Does the term "UFB" only relate to fibre connections, or can it also refer to VDSL connections?

4) is WPS still a security flaw on modern modem/routers? eg Do they now actually turn off wps if you select this option in the settings?

thanks in advance for any help
