Joined Network but Self-Assigned IP from ethernet.
I am trying to use my previous generation Airport Extreme to act as a wireless switch for my PS3 that can't seem to find my network up in my room. I managed to get the airport to join the netowork of my Netgear WNDR3400. Connecting through wifi is fine and I can manage the airport when connect to said wifi. It is when I try to connect through ethernet that I get a self Assigned IP using DHCP and Airport Utility can't find the AEBS. I have tried manual address using DHCP and manually configuring both the Airport and the Wifi connection on my MacBook Pro to make sure it works before connecting to the PS3, but as of yet I have had no luck getting any kind of inernet connection through ethernet.
If I'm posting on here it means I've spent several hours trouble shooting with no luck 😕. Thanks for any help.
MacBook Pro, OS X Mavericks (10.9.1)
