Wifi Adapters, PCI vs USB

[Japster]

I'm looking to buy myself a wifi adapters for my pc's. At present Im using D-Link DWA-121 Wireless N USB adapters, but i have been having serious issues with it. It has no range and when we are playing games via LAN it causes massive lag.

Now what I want to know is, does the pci adapters give much better performance then the usb adapters?

The card I'm looking at buying is the D-Link DWA-547 Rangebooster 650N. I do not know if anyone have ever used this card. What I do see is that it only support the 2.4Ghz range and only the 802.11N Draft. Well the 2.4Ghz frequency limit is not that much of an issue though.

The PCI cards usually come with better antennas, so they should also work better than the USB ones.

USB 2.0 has a small power output limit (like 0.5A, which is 2.5W @ 5V), but it should be more than enough for WiFi, because WiFi is usually like 100mW (or less even).

Wireless N is also useless if you don't have a Wireless N AP (Access Point).

That D-Link DWA-121 (Wireless N150 Pico USB adapter) one that you have will have a terrible range due to it having no external antenna and its internal antenna would probably be terrible too due to its miniature size!

You can get an affordable dual band (2.4GHz / 5GHz) PCI 300Mbps WiFi card with nice external antennas for like R400: http://www.wootware.co.za/gigabyte-...-0-2-4-5-0ghz-dual-band-pci-e-combo-card.html
From the design, it even looks like you can swap that wireless module out (with this PCI card) for a laptop one, which you may want to do when you get like an 802.11ac AP.
