@Bocon,

If your office and TL-PA211 are on the same circuit you can simply add a powerline connection into the office. Some of our powerline devices will be able to broadcast and extend your network from your house. If they are on different circuits, your results could vary greatly. Keep in mind, however, that devices such as Range Extenders and Powerline Connectors will have a lower connection than hard wiring an Access Point.

The other option would be to use a Range Extender to Extend your network, however, this comes with a steep dropoff of speed by default, often seen as 50% Speed when using Range Extenders. However, Any kind of upgrade that ups the overall bandwidth of the network will cause the network to operate at higher efficiency. While this may not result in more speed, the network should be more stable due to not having to prioritize traffic as much.
