Dual Wifi Connection?

[Yingda Wang]

Hi,
I have 2 wifi adapter installed in my sytem.
What happens if I connect both card to my router at same time?
Does it provides better connection and better speed?

Dont think so.

It will only use one or the other. It needs very special software on both sides to bond connection together. Both your PC and the router would have to support a method to do it.
It really doesn't matter current 802.11n uses 40mhz of the 60mhz total on the 2.4g band (so there is not room for 2 40mhz signals) and 802.11ac will soon have the ability to use 160mhz out of the total 180mhz on 5g with a signal adapter.

So the adapters are already trying to use all the bandwidth.....and so are all your neighbors which is why everyone get poor performance.

one card runs on 5 g and the other one runs on 2.4. The 5ghz band has higher download speed but has occational lagg spike which is annoying for gaming. The 2.4 is about 20% slower but doesnt lagg spike :O.
Any way to get the better of both world?
Both are pcie based.
First one is a cheap realtek adapter(2.4ghz) and the other is a Intel Centrino Ultimate 6300

I wouldnt trust Intel cards. Their drivers are buggy and can crash a system

You can not connect both to the same router..you can connect to different router/subnets but you can not put them both on the same subnet.

The windows driver prevents this and only allows one nic to function. If you dig you will find discussion of bonding these but so far I have not found free code to run in a router that can do this. There are a couple commercial companies that sell custom solutions.

Still none of these run on windows they are used to create bonded point to point links.
