The internal brick walls in my old house significantly reduces the wireless range of my D-Link WBR-2310 router. I would like to move up to an AC router, and from articles I've seen online, I understand that I may be able to use the older router as an access point.
I currently have an ethernet cable running from my office in the back of the house to a laptop and HDTV in a room at the front of the house. For watching TV or connecting via the laptop, the ethernet connection is excellent, but the wireless signal in the TV room is virtually unusable -- typically ~-75dB (vs -40dB and better in the office).
I have found several articles online about how to turn a router into an AP for wireless connections, and feel reasonably confident that I can follow the instructions to do it. However, I am unclear about whether this will allow seamless roaming with portable devices. For example, will I be able to walk from the office to the TV room with my Nexus 7 while it is streaming a YouTube video?
I'd appreciate any insight into this -- and especially if this is not a reasonable solution.
