Does WEP Affect Wireless Performance? in Wireless Security http://www.dslreports.com/forum/r20961224 en Wed, 11 Nov 2009 03:42:06 EDT Wed, 11 Nov 2009 03:42:06 EDT Re: Does WEP Affect Wireless Performance? http://www.dslreports.com/forum/remark,21037441 Anav : Yes, I asked for a captive portal feature but it did not get into the mix. Its a matter of volume usage to add a feature, at that price point every penny counts. I was basically asking for an on-board SSL type authentication list, so no need to use an external server, and would protect password and user name. Could be useful in many situations.]]> http://www.dslreports.com/forum/remark,21037441 Sun, 31 Aug 2008 19:56:01 EDT Re: Does WEP Affect Wireless Performance? http://www.dslreports.com/forum/remark,21017692 anon :

If you need to run WEP this is the best way to do it. That way you will only lose internet bandwidth (unless the bandwidth thief is doing something illegal with the stolen bandwidth). ]]> http://www.dslreports.com/forum/remark,21017692 Wed, 27 Aug 2008 22:22:54 EDT Re: Does WEP Affect Wireless Performance? http://www.dslreports.com/forum/remark,21017672 anon :

Only if the neighbors don't want in anyway. When using WEP anyone who wants in will get in. How long it takes depends on how fast they read the articles describing how to get in and how long it takes them to download the tools to get in.

As long as people using WEP understand that it is basically no security at all there is not a problem. It is people who think WEP makes them security who are most at risk.]]> http://www.dslreports.com/forum/remark,21017672 Wed, 27 Aug 2008 22:19:30 EDT Re: Does WEP Affect Wireless Performance? http://www.dslreports.com/forum/remark,21015836 Bink : Thanks/very cool. So while it can’t act as a captive portal, you can still set bandwidth restrictions on your guests.

You won't notice the difference unless you have an older router or network cards that have a "bad" implementation of WPA that slows things down or causes the router to reboot. But if you have the WRT54G, you are golden! For older equipment, WPA-tkip is easier to implement then WPA-aes.

Go WPA and sleep well at knight knowing no one can get in! Just use a long enough key.

You can also turn off the "broadcast ssid info" to keep nosey people from seeing if your wireless AND change the DEFAULT router name.]]> http://www.dslreports.com/forum/remark,20976412 Tue, 19 Aug 2008 20:30:22 EDT Re: Does WEP Affect Wireless Performance? http://www.dslreports.com/forum/remark,20966894 Nerdtalker : WPA2 simply mandates AES. There are a number of other changes, but for your PSK implementation that's really all that you'll need to be concerned about. I'd recommend using AES either way. The length of the PSK is really what matters.

No, this doesn't affect gaming. Honestly, I never ever ever game over WiFi to begin with if it's anything really latency sensitive (FPS, RTS, e.t.c.). I guess you could get away with MMOs and the like, but, I just spare myself the frustration in general. There's a certain amount of potential for random latency introduced which is inherent in wireless itself.

Yes, I'm sure there's overhead Bink See Profile. The point is that it's so negligible it's impossible to really differentiate from interference/normal throughput drops from the fact that the interfaces are wireless to begin with.

WCN saves off the settings to a flash drive so you can reconfigure your clients if required or add clients easily. If your wireless access point/router or clients do not support WCN you can easily copy-n-paste the network key by opening the flash drive and navigating to the \Smrtntky\Wsetting.txt file and copying the key to the wireless access point/router or client. Links here along with my general wireless guidelines.

Personally I use a 63-character random ASCII key and WPA-PSK [AES] to secure my home wireless network, ie. an XP Pro wireless desktop client and a laptop running Ubuntu or Vista Ultimate.

If your router is fast enough, there isn't any throughput hit to speak of, honestly.

Additionally, if you're going to bother implementing encryption, WEP is strongly not recommended because of its inherent insecurity and ease-of-cracking. WPA/WPA2 with either TKIP or AES and a 20 character random password (everyone has already said as much) is accepted as bulletproof right now. WEP on the other hand, is insecure.

Performance will not be degraded because there is a bit-overhead to encrypting the traffic; these schemes are 1:1. I've read a few tests and haven't seen any throughput hit to worry about.

As long as it isnt 0123456789 ;-)

As for 802.1X, I would certainly recommmend that for any office usage, especially if handling other peoples information.

Certificates and rolling codes certainly add another layer of security for business purposes.

Use WPA-PSK or WPA2-PSK and use at least a 20 character key for the only wifi security you need to setup.

It is also recommended that you have as large as possible random ROUTER password as well.

Here is one random generator service.
