So, this isn't a FFXIV issue, but it is something that's causing me issues. I have both a PC and a laptop. My laptop has no issues connecting wirelessly to my home router, but it's incapable of playing FFXIV. My PC can run FFXIV, but has MASSIVE issues connecting to the router.

In a position where my laptop, with an internal wireless NIC, is getting 4 bars, my PC is getting 1, or 0. Oftentimes it just stops seeing the router altogether, disconnecting me. I've tried with numerous wireless NICs as well as a NIC card inserted into my PC with the antenna (against all expectations, the card performs worst). It seems to be an issue with my router, but I can't understand what could POSSIBLY be the issue.

Does anyone have any idea what about a PC could make it struggle to receive wireless signals?
