Hi Everyone.

I new to the whole home theater thing and have a question I can't seem to find an answer to.

I just purchased a LG LHB977 blu ray home theater system. I also have Comcast internet for my home (it's not a home network or anything, I do not have a router of any type. I just go from the wall to the cable modem and from the cable modem into my computer). On my b-ray there is a place where I can connect an ethernet cable. So I thought that I could just unplug the cable that goes from the modem to the computer (leaving the connection to the wall intact) and plug in the cable that goes to my blu ray player. Well I did that but my blu ray player says there is no internet connection. I'm guessing that I can't do that type of hookup (since it isn't working) but I don't know what I need to hook it up because I do want to stream Netflix and get software/firmware updates.

Any help anyone can provide is greatly appreciated!!

You now have more than one device on your network, so you'll need something to "split" the internet signal from your modem.

I would purchase a wireless router with 4 ethernet ports. See an example here. You do not have to use wireless unless you want to now or in the future.

Connect the single cable coming from your modem to the "Internet" port on the router. Then use ethernet cables to connect both your computer and blu-ray player to separate blue ports on the router..

But the OP did not add two devices. He just unplugged the ethernet cable from his computer and plugged it into the BR player. Is that correct? If so, it should have worked. May be the DHCP server did not give an IP address to the BR player. You need to troubleshoot more. You can try rebooting the cable modem and see if that helps.

But he linked the PC to the BD player not the hub

On his network the hub is the DHCP server, and the PC is a client

So basically you have two devices connected together and the following conversation going on

BD: Hey there, can I have an IP address please?
PC: I was just going to ask you the same question, dont you have any?
BD: Nope, I need to get one, dont you have any to give me?
PC: I was just going to ask you the same question, dont you have any?

etc etc ad infinitum

The BD player wants an "internet connection" not a peer to peer connection, so it would only work if he cabled it directly to the hub in that scenario

Otherwise he could put another network card in his PC and share the connection to the BD player

But the most versatile solution is the one suggested earlier where he buys a cheap router (NOT a hub) and plugs both devices into that and connects it to his modem

If you have two IP enabled devices and you would like for them to share an internet connection you will need a router.

Cable Modem>Router>networked computer and BR Player and any other device.

The topology is hub and spoke (like a bicycle rim). Hub being the router, spokes being the networked devices.

Hit dealnews.com, spend $20-40 and be done with it.

An audiophile likes to talk about how much they spent and how good it sounds.

A DIY'er likes to talk about how little they spent and how good it sounds.
