Encrypting slows down the router =S?

Hey there!

I have just got a new router. The Asus RT-N16. I have just used it for a LAN-party, and it worked great, with 25 megabit download and upload speed. But when I use it wireless with WEP or WPA encryption, it slows down to 14/14!

The only thing that solves the wireless problem, is to take the security off. Then it works flawlessly.

I have also tried to switch channel. No luck. How do I fix this?

Kind Regards, Peter


EDIT: I fixed it! I turned "B/G protection" off. What does it do ? I was able to get 20/20 with wep and 25/25 with WPA

 

You are not specific enough- does WPA mean WPA or WPA & WPA2?
Anyway- current generation of Wi-Fi chips is optimized for WPA2 + AES and anything else like TKIP not to mention WEP will severely reduce throughput.
I admit it's one of those things that may not seem to make sense when you hear it but that's how it is- there’s an article and test conforming this on smallnetbuilder somewhere.

 

Thanks for your answer.

But after I turned "B/G protection" off, it runs MUCH faster - Even with WEP. Why does it do that?

 

I have no idea what settings on RT-N16 are but still the principle stands- use WPA2.
I couldn't find the article I mentioned but I found this in one of the tests on smallnetbuilder.
For this particular router throughput had been reduced by 71% when using WEP and 75% for WPA-TKIP compared to non-secured connection. WPA2 means only 10% of the throughput lost. That was for uplink.
For downlink it's 63% lost for WEP & WPA and no loss for WPA2.

This number are specific for tested router or rather its radio chip but the principle stands for all modern routers- you lose a lot with if not using WPA2.

You are right. With WPA2 (AES) I get 26/26, that means, nothing is lost!

But then I found out that my brothers computer doesen't support WPA2. Damn! But we think we can live with the standard WPA-Personal (TKIP), we only loose 2-3 megabit.

Thanks for the answers.

 

That's gotta be an old one. I haven't seen anything that doesn't support WPA2 since 2005. Driver update maybe?

 

Check if your router has WPA/WPA2 Personal Mixed mode (TKIP+AES), which allows both WPA and WPA2 devices to connect.

 

It's a special edition of WGA 111 v2 wireless card. Yes, there is a driver update, that makes it possible to use WPA2, but the driver doesen't work.

I actually have a normal version of this card, and on that, the driver works.

Flipfire: Thanks for the tip! There was a option for that! Thanks mate
