Affiliate Marketing Secrets

I have a D-Link DIR-615 wireless router operating to 802.11n installed in my office. Unfortunately, the signal is very weak in the room and niche where my LG DVD player (with wireless capability) is, making watching streamed Netflix shows on the main TV nearly impossible. Plus, my house is not wired for ethernet, and there’s no easy way to run an ethernet connection from the router to the DVD player. I’ve heard that I could get another router that will act as a repeater, buy a repeater (one Yahoo Answer mentioned a bi-directional Wi-Fi signal amplifier; not sure if it’s the same as a repeater), or perhaps buy a newer router that has longer range. I’d greatly appreciate your ideas on a cost-effective solution. Thanks in advance.
