@C9Clarkey ,

This once again proves the importance of double-checking configuration information.

This is also definitely a recommended solution.

So after all this time it turns out i was getting the password wrong!

When i was given it originally it was over the phone as the live chat messages wasn't coming through for me so they rang and gave it me over the phone, nonetheless clearly there was a mix up as to what letter were uppercase and lowercase. 

I only knew about this today when I went back on the live chat to start a new one to confirm that vodafone weren't blocking me from using a 3rd party router and to get the details again. However, this time I did recieve there messages via the chat so they were able to email me the details and low and behold the problem different password. 

I then went to check to see if it worked using the VLAN ID i was given and it didn't so i did the very first thing that was suggested by @Tail_uk and as if by magic it worked - so i've now got a functioning router without using the ISP router

Thanks to all that has responded with this trying to help figure out what the issue was!
