Wireless speed haircut using wpa vs wep vs no security.

I'm just curious what type of speed haircuts people experience when using wpa vs wep vs no security. I would have expected something like a 10 to 20% decrease in download and file transfer speeds instead of what I'm seeing.
My non scientific tests are as follows:
d/l u/l
wpa
1.280 692
1,189 338
909 1,602
wep 8.089 1,043
no security
11,485 1,658
4,813 1.072
3,047 1.842
Please ignore the obvious anomilies in the test speeds other than the slow wpa transfers.
The tests were taken at dslreports, but reflect my "real world" observations including transferring files. I used a linksys 54GS router, a linksys54??? wireless desktop card running on a 15MB cable connection. The connection was establish using netcfg2.
I was just curious if other people are experiencing the same type of speed slowdowns using wpa. Before I started using netcfg, I assumed I screwed up, but the information needed for netcfg seems pretty simple and basic.
If this is typical, I might turn the access point off, and use wep when I need wireless access.

upstream results are not the best test scenario, as they are entirely too variant.
For testing, I would connect a box to one of the ethernet ports on the linksys, and then use iperf to test between a node on the wireless to the wired node.
note: wireless is more suseptible to packet loss, so udp throughput over wireless will most likely be crappy. Make sure to test with tcp instead of udp.
It was my "real world" experience that caused me to make the speed tests and to try wep and no encryption. The tests only confirmed what I was already seeing and was drastic enough to not be concerned about speed variations or anomalies. WPA browsing was sluggish with d/l speeds of 1 to 1.5 MBs but both WEP and no security was responsive with good downloads including pacman upgrades. I am usually able to close to my rated bandwidth of 15MBs using WEP with 128 bit encyrption.
The wireless card is in a desktop and would be a pain to connect with a cable. The fact that I'm getting such good speeds with WEP indicates that the router and card are working OK. At this point I'm just going to go with 128 bit WEP encryption and try to turn off SSID broadcasting when I'm not using the wireless computer.
I pretty much assumed it was my fault when I was using ifconfig, iwconfig and iwpriv to make the connection, but netcfg2 seems pretty easy and hard to mess up. I'm really not that concerned about the security with WEP, but I was curious if anybody else had the same type of experiences.
Thanks

Can WRT54G use WPA and WEP at the same time?

I used to have a smc 802.11b wireless router and a dlink 802.11b wireless print server.
In order to have WPA and a firewall, I replaced the wireless router with a linksys WRT54G.
Then I realize the dlink print server, even though it has the "g" keyword in the model name, does not do WPA (DP-G321).
Do I have to buy a 802.11g wireless print server? Or is there another solution?
I don't supposed the linksys router can do both WPA and WEP at the same time?
Connecting the print server to the router with a cable is not feasible. They are on different floors.

both of your devices are has a wireless b technology settings, just set a wep encryption on your network rather than wpa because some wireless b devices don;t work with wpa. with regards to your query if wep and wpa can be used at the same time, the answer is no.

Creating Wireless Security- Use WPA or WEP?

I need to know which wireless security to use. I need to note that I am sharing the wireless connection with my roomate's Windows PC.
Which one of the following do I need to use:
-WEP Password
-WEP 40/128-bit hex
-WEP 40/128-bit ASCII
-LEAP
_WPA Personal
-WPA Enterprise
_WPA2 Personal
-WPA2 Enterprise
-802.1X WEP
These are all of the choices it gives me in Network Preferences. Any advice would be greatly appreciated. Thanks

WPA2 Personal gives the best security. I suggest you use that unless there is a reason not to, e.g. incompatibility with your non-Mac equipment. WEP is much less secure and has inherent potential incompatibility problems.

Slow wireless speed with PPPoE

I'm using a WRT54G wireless router configured with PPPoE connected to a DSL router which is acting as the DHCP server. The DSL connection is 10 Mbps. I have two roommates wired to the router and me and another roommate wirelessly. The two computers that are wired directly are getting speeds around 8.5-9.5 Mbps, but I'm getting 3 tops. And lately its diminishing to a few hundred Kbps. while the others are still up at full speed. Is there some setting on the router that is throttling down the wireless speed when using PPPoE? Thanks

Wireless connections are always slower than wired connections, but in most cases, you should be able to achieve at least 50% or more of the wired speed (unless you are so far away from the router that your signal is poor just from distance).
There are many causes for poor wireless connections, and many solutions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your wireless card.
If your troubles persist, note that with newer routers, some users have found that WPA or WPA2 encryption works better than WEP.
If you still have trouble, for wireless g routers, try setting the "Transmission Rate" to 54 Mbps. For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
Another option is to try to adjust the QOS (Quality of Service) options on your router. You might be able to give yourself a higher priority, and the wired connections a lower priority.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

Wireless speed difference with WEP and WPA2?

I am connecting to my FiOS router wirelessly, since I was new on wireless networking, I did lots of reading they all say WEP encryption is flawed, and WPA2 should be used instead. So I changed the router's default WEP to WPA2 the same day I got FiOS installed. When I check about 10 of my neighbor's wireless networks, 8 of them using WEP, 1 has Security Disabled(D'oh), and I am the only one using WPA2-personal. My question is will I see any connection speed difference between using WEP and WPA2?
Solved!
Go to Solution.

in every day use, your experience will vary. There is more "going on" with WPA and WPA2 than with WEP, such as message checking and encryption key changes for each data transmission, so these, combined with other possibilities inherent in computer-connected-to-internet use, can slow you down. Another factor: There will be more administrative overhead to use WPA or WPA2. such as if you ever have to reset the router (to default settings), the default is WEP, so you have to go into the router to then chage it (or import a config file you previously saved on your PC). AND If you need to call verizon tier one tech support, they only support default settings. Their premium service is called Expert Care.

Leopard problem connecting with wifi AP using WPA PSK instead of WEP

I cannot connect via Airport to Speedtouch 580i accesspoint using WPA PSK.
WEP works just fine, but using WPA PSK I keep getting the message invalid password and then cannot connect wirelessly.
Tiger as of version 10.4.3 through .11 worked flawlessly via WPA PSK with the same AP.
I installed 10.5.4 Leopard from scratch and used combo 10.5.5 and and a few days ago combo update 10.5.6 but problem remain.
After the clean install I used migration assistent to get user data and logins from Tiger into Leopard, having used an image made with SuperDuper.
I have read many support forums and suggestions, it all didn't result in a working internet connection at all with WPA PSK :-...(
What I did until now:
- Disabled IPv6 for the airport interface
- Changed to a simple WPA PSK password without CAPITALS instead of something like #A!$($D$%\T@q{|
- Changed to a fixed channel in the wireless accesspoint instead of auto. http://discussions.apple.com/thread.jspa?threadID=1195706
- Rebooted Accesspoint various times.
- Changed to 802.11g only instead of b+g
- Tried both TKIP and AES as encryption type
- Disabled and re-enabled Firewall in Leopard
- Changed to fixed ip adress instead of via DHCP for network addres assignment
- Tried connecting with and without broadcast of SSID to AP.
- Repaired keychain , http://discussions.apple.com/thread.jspa?messageID=5858982
- Did various keychain changes incl deleting old values
- Deleted some items from library, as per suggestions from forums.
In the end I have a suspicion that it all drills down to something simple, quotes (" ") are used to present the password in the password field, at least this is the case with WEP, but this does not harm the functionality for WEP as this is working alright.
With the current WPA PSK implementation it perhaps does influence, because it keeps saying invalid password. I have tested both with and without quotes and things did not improve at all.
I'm running out of ideas to solve this matter, therefore I have sent a report to Apple via their Feedback webpage.
While having using 10.5.5 fo a while I had big hopes 10.5.6 would cure the problem , unfortunately this is not the case.
Please provide more suggestions to solve this problem.

Checked Accesspoint firmware upgrade. The only difference between the current 4.2.7.25 and the latest version, 4.2.7.30 is the support of WDS i.e. expanding the wireless network by connecting 2 APs together (via WEP).
Still tried upgrading via the MAC OS X update software, it did not fire up, I think the software is not fond of Leopards
As WEP works ok with Leopard on my G4 Powerbook 12inch, I didn't want to focus further on the speedtouch because of the motto 'if it ain't broke don't fix it.'
Am going to research more on Keychain and DHCP, others are reporting issues with it along with this 'airport crisis' http://forums.macrumors.com/showthread.php?t=375838

WPA versus WEP for Wireless Routher Setup

What is the difference between WPA and WEP for the wireless router setup?
I have a WRT160N router and after a lot of hassle and downgrading my firmware to build 8, I had to change the wireless setup from WPA to WEP in order to get my wireless laptop to connect to the internet.
Previously, I had been able to connect with the WPA setup, but after the firmware downgrade I was unable to connect and customer support had me change the wireless setup to WEP.

Hello jns, WPA is stronger than WEP encryption. Check out their description.
Wired Equivalent Privacy (WEP) is a 64-bit key with 10 hexadecimal digits or a 128-bit WEP key with 26 hexadecimal digits. This encryption will prevent other users from connecting to a wireless network using your own WEP key. It will also protect your wireless transmissions/communications from being accessed or received by other users.
Wi-Fi Protected Access (WPA) is a Wi-Fi standard that was designed to improve the security features of WEP. WPA is stronger than WEP encryption. PSK and PSK2, types of WPA, give you a choice of two encryption methods, TKIP (Temporal Key Integrity Protocol), which incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes a symmetric 128-Bit block data encryption.
If your PC is using WinXP SP1 then WPA is not advisable for your wireless security because WinXP SP1 is not supported with WPA, you can use WEP for your wireless security but if your PC is using WinXP SP2 or Vista OS or MAC then I suggest you use WPA personal for your wireless security to make your wireless key stronger.
Hope that helps!

Need help with wireless speeds..

I just got myself a WRT54GS wireless router and i have noticed the speeds being extremely slow. I've gone through all of the threads and didn't get anything that could help. I have tried what some mention, about changing the beacon interval to 50 and the Frag and RTS to 2304. Also i have changed the wireless channel a couple of times. Still nothing..
Now onto my connection in general, i have cable and the speeds when direct connected are very fast. I typically download at about 300kb+ and i can get mb download speeds as well. But while hooked up wirelessly it has been going at about 20kbs. When i try and watch streaming videos and all, it will be break up and all of that..due to the slow speed. BTW i don't believe there is anything interfering at all. The comp is in the same room as the router as well
This is my first time dealing with wireless, so any info and help would be greatly appreciated. What are some good ways to get the speeds up? The comp i have is new as well lol I know it limits a lot of the help, but this is a pain in the butt. Thanks

What encryption are you using? WEP? WPA? WPA2? Some systems work significantly better with one encryption system vs. another. So try something different. WEP is no longer recommended. You should be using WPA or preferably WPA2. Password (key) should not have any spaces in it.
Windows XP requires a patch to run WPA2 (= PSK2 = WPA with AES ). Go to Microsoft Knowledge base, article ID=893357 and it will direct you to the patch.
Sadly, the patch is not part of the automatic Windows XP updates, so lots of people are missing the patch.
Hope this helps.

Slow Wireless Speeds WRT160N V3!!

I know this has already been posted several times and I actually took the time to go through most of the threads regarding this issue. I still cannot fix this problem. My problem is that my speed is suppose to be 30Mbps but using wireless, it is only around 10Mbps. These values were provided by speedtest.net. Connecting directly to the modem or using a wired connection from the router gives me 30 Mbps but the speed is much slower using wireless.
Here are my current settings:
FW: v3.0.02 build 004
MTU: 1350
Network Mode: Wireless-G only
Channel: 7
Security Mode: WEP
Beacon Interval: 75
Frag Threshold: 2304
RTS Threshold: 2304

Just so you know, speedtest.net and the likes are not accurate in measuring the actual speed your ISP is providing. I suggest connect to the modem. Download a large file from the internet, measure the download speed and how long it took to download. You do the same using the router's LAN port then wireless.
You might want to use WPA or WPA2 to secure your network. WEP is kinda old and insecure. While testing the speed, disable it in the meantime.

Just got a new IPOD Touch and it wont connect to our Wifi home network with a Belken N Router. Our router uses WEP 64 bit security, but had a "blank" password field, which the IPOD did not like. Changing to a 6 char numeric PW didnt help either.

OS is whatever OS ships with current IPOD Touch
I cannot understand why the APPLE engineers have designed this product so that it has SO MANY WIFI problems. This is supposed to be an easy-to-use product. We've had no problems connecting our new laptop, our ROKU box, etc, but it seems impossible to get the IPOD touch to work. NOTHING LIKE SPENDING XMAS MORNING DOING APPLE TECH SUPPORT TROUBLESHOOTING TO LEAVE YOU IN THE CHRISTMAS SPIRIT!!! Argh!
In fact, the only way we have been able to get this expensive brand new IPOD to work on our home network is to DISABLE SECURITY in the router settings. THIS IS ANYTHING BUT A GOOD IDEA.
DON"T KNOW WHY BUT MANY OTHER USERS ARE REPORTING THE SAME KIND OF PROBLEM SO APPLE ENGINEERING NEEDS TO GET BUSY AND FIX THIS PROBLEM SO THAT NEW USERS CAN CONNECT TO THE INTERNET WITHOUT HAVING TO BE TRAINED ROUTER ENGINEERS TO DO IT!!!!
Ok, sorry for the rant, but surely those of you who are experiencing this share my frustration. This is not why I bought an APPLE product.
IS THERE ANY POSSIBILITY THAT APPLE WILL NOT ALLOW A WIFI PASSWORD with more than one identical alphanumeric character? Any ideas? We also tried eliminating the 40 MHZ setting under Bandwidth settings in the router settings for our router, but it made no difference. The router has the latest firmware, too. Running out of ideas, and am ready to box this unit up and send it back!

Thanks, Bob! You are correct. And, we learned this as we spoke with APPLE TECH SUPPORT by phone on Christmas day (800-APL-CARE). One of their reps spent the time to help us troubleshoot this, but the boiled down conclusion is your answer, and to repeat for the benefit of others, here is what worked:
1. With our Belkin router set to "out-of-the-box" WEP 64 bit security, we could not get wireless access of any kind. Only with the Security Mode set to DISABLED, could we gain access.
2. Changing the router's security mode setting to "WPA/WPA-2...." and entering a new min. 8 char passphrase, and then entering that same passphrase into the IPOD Touch, and restarting the router, did the trick!
Based on this, and some info found in another posting, I can only conclude that the IPODs and IPHONES do not support WEP security mode in many generic routers used by thousands of consumers. Hopefully, those same consumers can figure out how to change their wireless router setttings to WPA/WPA-2 security mode and ALSO get all their other wireless devices (PCs, laptops, WII boxes, ROKU boxes) all reconfigured to WPA mode, too.
I THINK THE BOTTOM LINE HERE IS THAT THERE IS AN ISSUE THAT APPLE NEEDS TO ADDRESS WITH WEP COMPATIBILITY and it may also be the case that MOST CONSUMERS ARE USING WEP 64 BIT security on their home wireless routers?
In any case, it's working now, so anyone who is having problems should try changing to WPA mode and post back here if it worked for them!

How best to get my OS 9.1 Powerbook to use WPA encryption

My Wall Street Powerbook (upgraded to G4/500 with a USB adapter and Wavelan Silver [WEP] wi-fi card) can sometimes see but not successfully connect to public (or private, even with the password) wi-fi networks. I get a generic Airport error message that it cannot connect. I think it's because the network are WPA and WEP won't work with them. Thus, I'm looking for a way to add WPA capability to my PB.
I saw a post elsewhere on this forum about wireless ethernet adapters that can be used for this purpose. Problem is, only some are OS 9 compatible or even Mac-compatible, and they run close to $100. The one that are OS X-compatible can be configured first there, then used with an OS 9 Mac.
On the manufacturers' sites I also see USB wireless adapters, which are much cheaper. Can they be used with my PB? If they are OS X-compatible I could do the configuration (whatever that means) on my OS 10.4.11 Mac Mini.
To tell the truth I'm not sure what "configuration" means with wi-fi adapters but it seems to be a one-time thing and you don't have to use the adapter with the device you configured it with. If that's the case, why couldn't I just go to, say, MicroCenter, buy either a wireless ethernet or USB adapter, and have them configure it on one of their Windoze machines (or does it have to be a Mac, even one running a different OS from the intended hardware?)

I saw a post elsewhere on this forum about wireless ethernet adapters that can be used for this purpose. Problem is, only some are OS 9 compatible or even Mac-compatible, and they run close to $100.
A number of wireless Ethernet bridge devices (also known as gaming adapters) have WPA capabilities (with or without a firmware update). To be sure exactly which model (or versions of a model), check the specifications. You may want to have a closer look at, for example, D-Link DWL-G820, Linksys WET54G and Linksys WGA600N.
Generally speaking, security and all other wireless aspects are handled by the wireless Ethernet bridge. No special drivers normally needed. Therefore, you should not have a problem with system versions in this very case. A wireless Ethernet bridge can be used with older computers under almost any operating system. The main disadvantage here may be size and the need for an external power supply, which would make the wireless Ethernet bridge solution a little less portable.

With a wireless Ethernet bridge, you could carry out the initial configuration via another computer. On the other hand, bridge devices usually require a normal web browser for this task, so it may be possible to use an older Mac, too. Once configured, the wireless bridge acts rather independently (necessary when used with network printers et cetera).
The situation is quite different with USB wireless adapters. These units rely heavily on special driver software in close connection with an operating system. Most USB adapters need at least Mac OS X 10.3 (if Mac drivers are available at all).

Internet disconnecting when using WPA

About 3 weeks ago my wireless connection started dropping on a regular basis. I would be on the web, and then i would not be able to access any pages. Everytime, I would have to power cycle the router and the wireless would reconnect....then about an hour later, same issue.
I contacted Verizon tech suppot and he could not connect to my router because I was using WPA for security instead of the default WEP. The tech told me that Verizon was trying to push out some updates or something and that they could not because I was not using THEIR recommended security settings of 64 bit WEP.....he said I would have to revert to WEP or I would continue to have problems.
I reverted back to WEP and have had no problems at all. Everytime I try to put WPA back, I have the same issue.
Anyone else having this issue?
Personally, if this is true, I'm not going to be very happy about this. So either the tech was an idiot or Verizon is being **bleep** by not allowing people to use a different security setting.

thats what i was thinking too. I'll have to check the setup for WPA, I have the Westell 9100 router, so I'm not sure it has the same setup as the ActionTec.
Thanks for the info. I'll check tonight/tomorrow and post my findings.

WRT54GL Can't set WPA or WEP and connect

Okay, brand new WRT54GL, setup on the network, can connect, no problem. If I goto setup the WPA or WEP and enter the corresponding info on the Windows machine, I can't connect to the router. It leases an IP, and I can see in ipconfig (dhcp client) that I have a IP from the router, the new router IP (I changed it to 250 to verify I'm connecting and not getting something legacy) shows up as my router, but then I can't ping it or connect to the router in any way. If I disable the WPA or WEP, it works fine.
Just for the record, I run WEP on everything I touch, home, work, family and friends houses when I set up their wireless, etc. I do networking day to day, but granted I'm not changing my WEP WPA regularly (often enough to consider myself safe, but not Best Practices regularly) so I know what's up there. But on this box, it doesn't do. This is my first foray into the GL (I was thinking of the WRT fw's, but this isn't my box), so I didn't know if there was something different I should look at?
So, as you can probably guess, this box isn't at my house, it's at my buddies. I can go over and check on things, but I can't do it immediately. I'ld like to just see if maybe I overlooked something stupid. The part that's throwing me off is that I've done this countless times. Does this sort of thing ever happen to anyone else? I'm trusting that one of the forum regulars can thump me on the head and I'll see clearly. He is using it right now in unsecured mode, so no problem there.

Tried resetting about a dozen times while I was attempting this the first time. I did that because I knew that would be the first thing I would be asked to do.
The only error I was getting was that Windows could not authenticate with the device. (I forget the error, and did not go over there this weekend). Wouldn't it be nice if Windows told you exactly what the error was? What has me stymied is that Windows got it's complete DHCP info from the router, but wouldn't let me connect to the router (or anything else) so obviously it did auth at some point.

I changed my WRT54G security settings from WPA to WEP

I changed my WRT54G security settings from WPA to WEP and now one of my latops (Dell 5100) will not connect wirelessly. It is using a linksys wireless-B notebook adapter. I am at a loss at how to reconnect this to my wireless network.

Go to the setup page of the router on the wired computer and click on the Wireless tab,check the network name(SSID),change the Wireless Channel to 11-2.462 GHz,Keep the SSID broadcast enable and click on save settings...Click on the subtab Wireless Security and change the Security mode to WEP or WPA as per your requirement.If you are using WEP then,note down the KEY1 as the network key(case sensitive)...
Now,on the laptops,delete the preferred network and then,try to connect the Wireless Network.

EA6200 in Bridge Mode Slow Wireless Speeds

Hello All,
I just purchased a Linsys EA6200 AC router (refurb) to extend my existing wireless network. I have setup the 6200 as an access point using the Bridge Mode outlined in the Users Guide (automatic configuration). While I am able to connect to the Internet from the router wirelessly, my Internet speeds while connected are roughly a third of my max MBPS, I have a 55 MBPS connection and consistently get speeds around 14-20 MBPS with this router from a 10-12 foot wireless distance. I get full speed while wired in, however, as soon as I go back to WiFI I get a significant performance drop.
Is there something that can be done to correct this? I am running the latest firmware and have set the 2.4G channel to 20mhz and the 5G channel to 40mhz while specifying a channel number with no increase in performance or speed. Any help would be greatly appreciated. Thank you.

What Mfr and model is the main host router?
Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or Mixed on 5Ghz on the main host router?
Channel Width set for Auto 20/40Mhz. 20Mhz can slow the wireless speeds down.
Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
