1. Replace the router to somewhere in between (if it's not included in modem)
2. Don't use the wireless built into the modem, but buy a router, connect with an Ethernet cable and put it somewhere in the middle.
3. A powerline extender. Connect with the modem/router on one side, with your TV (via an Ethernet cable, or another router if it needs to be wireless) on the other side.
I was kindly given a 40" tv, Samsung LN40E550F7FXZA. I ordered a replacement remote that will arrive today. I've been looking for a wireless adapter so I can watch Hulu & Netflix, but not wanting to spend hundreds if dollars on one. The router is on the other side of the house. Not a big house, but still can't find a signal.
I have found the manual and followed instructions to try to find my network (using the buttons on the tv) with no luck, just says "weak signal".
I'd appreciate some good suggestions.
