I recently bought a Samsung Smart TV having in mind to connect it to the Internet. Because my router is very far from it and not wanting to buy an expensive wireless for the TV, I created a homemade solution. I have the laptop (an smartphone and the PC) connected to the router which is connected to the internet. I shared the laptop's wireless connection to the ethernet port which I connected to the TV. So far, the TV is connected to the internet, but is there any way to make him part of the router's network instead of the 2 devices network (the laptop and the TV)?

Does the solution you require have to be free? –  Bon Gart Jul 2 '12 at 23:38
    
Not necessarly, it could cost around 10-15$ –  Serban Razvan Jul 3 '12 at 10:01

Hm. For $10-$15 your solution would be an ethernet cable. I know, you don't want to run one... but that's the solution that fits in that budget.

For $25-$50, you could get a Wireless Ethernet Bridge... like this TP-Link WA500G. I present this particular one simply because if you shop around, you'll find it fits within that price range. There are others as well that will cost that much or more (Poke about eBay for a Linksys WET54g perhaps). This is a good solution because you configure the device itself to connect to your wireless network. It then passes an internal IP address to the device you connect it to... your TV. Your TV is now on your internal network and within the same subnet as all the other devices on your network... just as if it had a wireless card itself, or as if it was wired directly to your router. I keep one of these handy for when I want to connect client's desktops to my network without having to install driver software. These things will work with any device that has an ethernet port.... game consoles, TVs, DVR boxes... you name it. There are even fancier ones that have 4 ethernet ports on them.

For $55-$100 you could go with a power-line adapter, as has been suggested. For that outlay of cash, you get a pair of special plugs that will turn a segment of your electrical conduits in the walls, into a network segment. There isn't any configuration like you would see with a wireless ethernet bridge. You just plug an ethernet cable into your router, plug the other end of that cable into one of the power line adapters, then plug that power line adapter into the wall. You then plug the other adapter into the wall near the TV, and use a second ethernet cable between the TV and the adapter. The more expensive ones will not take up the wall socket as they come with a power pass-thru, but the ones at the lower end of the price range don't have pass-thru plugs... so in order to use them you would need to be able to give up a wall socket. Can be an elegant solution, but then again, can end up being more expensive than you need it to be.

Thanks, I think I will use an wireless ethernet bridge, as it is an excellent way to connect more devices to the network, but also it will be cheap enough. Thanks again –  Serban Razvan Jul 3 '12 at 14:23
    
@SerbanRazvan take your time on this when searching for one. This is one of those pieces of hardware you might be able to get more cheaply if you dig around. eBay is a great possibility, if you first get prices and models of some inexpensive 802.11g based ones, and then search the auction sites for them. Online hardware retail gateways like pricewatch.com might help you locate one for $5 to $10 less as well. –  Bon Gart Jul 3 '12 at 14:31
    
Thanks a lot for the tip! –  Serban Razvan Jul 3 '12 at 14:54

The question you really have to ask yourself is why you want the TV to be part of the same subnet as the router? If there is no functional difference, then why bother? But if you must make them part of the same subnet, I would suggest bridging the two connections. Here is a link on how to do that:

The difference is that the Android app for remote controling of the tv only works if the phone is in the same subnet with the tv –  Serban Razvan Jul 3 '12 at 8:41

Just get a power line adapter! You'll need 2 but it basically lets you run Ethernet through your homes electrical wiring! Here's what I'm talking about (not endorsing the vendor either):
