I'm not sure if this is the right forum for this, but it's a networking question.
I have in my basement a router (DLink DIR-655) which is connecting to our ISP, and I have cables running to wall jacks in the first floor. A wall jack which terminates in the living room I have connected to a switch, a DLink 10/100/1000 (DGS-1005G). To this I have my PS3 connected which can connect to the internet fine (although it seems to not get the same upload / download speeds other devices get) and my Sony Bravia TV (KDL-46Z5100). The PS3 registers as GB, while the TV 100MB (its port lights orange).
The problem is I can't get the TV to connect to the internet. If I try DHCP, it doesn't seem to find the DNS server (on another switch connected to the same router in a different room). If I hard code the IP address, still nothing.
I found that if I connect the TV directly into the wall, it can connect. It's just through the switch I'm having problems. Additionally, even if I then plug it back into the switch and connect the switch to the wall jack, the connect continues to work. It just seems that I can't get it initialize when connected to the switch.
