Will encryption always make wirelss slower?

I am currently running a Wireless N router and N PCI card and N based network card at my home. I simply use MAC filtering as my protection. I have stopped using any sort of encryption from the days of WEP. Do the newer ones case slowdowns etc on a wireless setup? Do I need to enable encryption to get anything special with N based setups or it works the same with or without?

Are there any drawbacks to using WPK or whatever the newer options are?
 
No, not at all. It's all done in hardware.

However newer devices are actually going back to doing wep in software because it's so old and considered "dead".

So encrypt your stuff or anybody can record everything you do. Just use WPA2/AES with a preshared key of 12 characters and you're good.
 
Yeah, we were using WEP on our router because of our printer and speeds across the whole network suffered. We found out how to get the printer to use WPA 1 even though its not technically supported or available in printer settings the wireless chipset inside could support it. Once we got it running WPA 1 the speeds went right back up and were pretty comparable to our use before using any security whatsoever.
 
Some of the 802.11b Wireless Devices while using WEP introduced significant slow down.

With the introduction of 802.11g and WPA the problem gone.

In theory encryption does insert few msec. delay but it is insignificant to proper work.

The main problem of Wireless id Environmental noise and physical obstructions of signal.

--------------------
From the weakest to the strongest, Wireless security capacity is.

No Security
MAC______(Band Aid if nothing else is available).
WEP64____(Easy, to "Brake" by knowledgeable people).
WEP128___(A little Harder, but "Hackable" too).
WPA-PSK__(Very Hard to Brake ).
WPA-AES__(Not functionally Breakable)
WPA2____ (Not functionally Breakable).

Note 1: WPA-AES the the current entry level rendition of WPA2.

Note 2: If you use WinXP and did not updated it you would have to download the WPA2 patch from Microsoft. http://support.microsoft.com/kb/893357

The documentation of your Wireless devices (Wireless Router, and Wireless Computer's Card) should state the type of security that is available with your Wireless hardware.

All devices MUST be set to the same security level using the same pass phrase.
Therefore the security must be set according what ever is the best possible of one of the Wireless devices.
I.e. even if most of your system might be capable to be configured to the max. with WPA2, but one device is only capable to be configured to max . of WEP, to whole system must be configured to WEP.

If you need more good security and one device (like a Wireless card that can do WEP only) is holding better security for the whole Network, replace the device with a better one.
