Hi this is a bit of a strange one

I have a TM Twin and up until 2 nights ago was working fine. Now all of a sudden (and i have done nothing to change it) it will not connect to the network

i have it set up on a static connection but here's the kicker i also have a sony smart android tv which is also on a ethernet connection on DHCP which is also not connecting.

however the pc connects fine to the ethernet connection (whichever socket i put it in) and on the whole the wifi works (it may take a couple of goes to connect to my phone)

strangely i can connect to my TM Twin via filezilla and can transfer stuff to the box.

has anyone any ideas what's up and how to solve it.

i'd be tearing my hair out if i had any.

thanks in advance
