About WiFi antennas
The main factor is the antenna placement. Even a high-quality antenna will struggle if it’s blocked between your device and a wall. That’s why, when installing a PCIe Wi-Fi card, I always recommend choosing one that includes a base for optimal positioning, as illustrated here.
Long antenna cables often cause more losses than benefits, so they’re kept short. To reduce these losses, use a much larger conductor—similar to cable TV coax. You don’t have to replace your router just for an Access Point; if you can run Ethernet nearer to where you need WiFi, you can add it alongside or even swap the whole setup.
You may want to explore Ethernet powerline adapters. When they function properly, they perform exceptionally well and resolved my problems when my PC was far from the router and Wi-Fi didn't work because a brick wall blocked the signal. These devices enable you to transmit Ethernet signals through your home's copper wiring.
