1.) Set up QoS (Quality Of Service) on your router. Though not the most efficent method, it may help stabilize the connection, though you may see latency issues on your hardlined machine
2.) Setting a dedicated channel for the wireless. This may or may not work depending on the WNIC on the laptop. Placing the laptop on 5Ghz and dropping the connection on all other wireless connected devices may reduce latency.
3.) Remove any wireless device that can only broadcast on the 2.5Ghz spectrum. These devices will be labeled with a "G" connection. If there is a "G" card on the LAN and the router does not have dual band, all devices that negotiate OTA (Over The Air) will be brought down to it's speed impacting performance.
4.) Relocate the Router. Try to preserve a stable LoS (line Of Sight) between the router and the laptop. Materials such as copper, aluminum, studs, or improperly grounded connections will resonate EMI (electromagnetic interference) impacting connection and performance.
5.) Purchase a dual band router. Ideally, these routers will have external antennas and have separate repeaters for the 2.5Ghz (G and below) and 5Ghz (N or better) bands.
6.) Run trace route and ping tests on the laptops connection. From the client hop, to LAN, to local server, you shouldn't have too much latency. The issue may not be on your end. If the spike occurs further downstream (Seattle, Chicago, Montreal), the issue isn't with your wireless network or equipment.
You may want to hold off on active troubleshooting though, as Square is currently set up to bring the servers down for what I imagine is going to be a physical MPLS and port upgrade on the racks and nodes Final Fantasy is hosted on. If accurate, latency should subside to tolerable levels.
