Can't contact DHCP server? (wired)

[H0ax!]

Came home today to Unidentified network, Access; Limited Connectivity.

After a quick Google, I tried most of the steps... I use homeplugs and both have a red LED for status and Green LED for ethernet, so I guess the cables are working okay? I've tried using a different network adapter, my IP and DNS are set to receive automatically, but I'm still getting this could not contact DHCP server. Also, I noticed my default gateway is blank, does this mean anything?! The only way I could connect was by wireless, my router is a BT Homehub...

Here is my ipconfig /all

Any help would be appreciated = D

Thanks.

Whilst at work today I realised I never actually tested the homeplugs with the laptop, just the cables!

Turns out it was the homeplugs preventing me from connectiong (they had previously worked for about a year straight with no problems). Just had to reconfigure the end point unit again... Apparently, we also had a power cut, which probably caused this^^^
