Title: WPA2 vs WPA...
Post by: Sammydad1 on August 31, 2011, 12:53:12 PM
Hi,

Was just re-reading at article from PC World April-2011 issue and one of the things they mention for speeding up wireless LAN speeds is to NOT use WPA for wireless encryption when using .11N because it runs at roughly 1/2 the speed of WPA2 encryption.

I had never seen that statement before, but maybe it has some relevance for folks in here seeing wireless speeds slower than expected ?

It's been generally known to run WPA2 and AES if possible and if devices can support these options.

I switched my setting from WPA/WPA2 to WPA2 Only....so far none of the kids have called me out to fix their networking....

See what happens over the next couple days....

Yea I sat down one day and tried to figure out what the difference is between WPA with AES and WPA2. Because when you look up WPA2 it says it uses AES. So wouldn't WPA2 with anything but AES be WPA? And wouldn't WPA with AES be WPA2? Is there some important difference? I know in use, there is. Just now a persons PS3 fat wouldn't connect with WPA2 with AES, but would connect WPA with AES. Its confusing.

The 802.11n spec states that the high throughput rates (link rates above 54 Mbps) can't be enabled if WEP or WPA/TKIP are used as they are outdated security methods. You also want WMM enabled on the router when using N.

WMM just conserves battery life with minimal loses on bandwidth. Granted, I think its a good idea to leave enabled, it doesn't really speed anything up. And while I agree the rates capable with N aren't possible with TKIP, that doesn't explain the different between WPA+AES and WPA2+AES. Both still use AES. Not only devices can connect at WPA2+AES. So whats the difference?

WPA and WEP use the old RC4 encryption scheme while WPA2 uses AES (Advanced Encryption Standard).

You can use WPA with AES though. I think the difference is the WPA2 standard forces while the WPA standard does not. WPA can either use TKIP or AES.
