Using multiple WiFi connections synchronously beneficial?

Hello!

I currently have one default WiFi connection (the card built into my Asus G74sx), but I also have another external USB WiFi adapter, a Hawking dish. I can use both separately, but I've noticed that I am often connected to my network by both at the same time. I was wondering if this has any sort of benefit: as in, does it improve speed/connection reliability/etc? Or is it the same as just having one connected?

Thanks, and if you need any specific information about the WiFi devices, let me know

Assuming both adapters negotiate with the base station at the same speed, running two WiFi connections won't make any difference. If one adapter is slower than the other, you could disable it to make sure your connection works at the highest speed available.
