I have a caption telephone that requires an Internet connection in addition to the traditional wired telephone connection. It has wireless capability, but the requirement for uninterrupted streaming sometimes is not consistently supported by my WiFi (LinkSys 2500 router). The phone is about 20 feet away on the other side of a brick wall. I can get 3-4 out of 5 bars on the signal, but experience some drops. I'm considering a power line Ethernet to get a more reliable wired connection to the phone. I would run a Cat 5 cable from one of the router ports to the powerline adapter unit and from the other adapter to the phone. The outlets are not on the same circuit. Is this a feasible strategy or is there a better solution? I thought of using a WiFi range extender, but my router does not have external antennas - the normal solution for upgrading the power output. Any suggestions along these lines would be welcome.
