BT hub 5 WAN not working [Help]

I have recently bought a BT hub 5 router with LEDE pre-installed but unfortunately the WAN isn't working and i cant connect to google ect, i have had no previous experience with LEDE. If anyone could help me it would be much appreciated.

more information please:
BT hub 5 A or B ?
How are the connection parameter from your ISP ?
for example which kind of xDSL do you use: VDSL or ADSL ?
which Annex ?

Have you seen the HH5A guide published here?
LEDE install guide for HH5A

see section 9 of the document.

Thanks for the swift reply, i already found the manual and worked it out by the end of the night but thanks anyways.
