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.

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

HT1695 changed broadband providers when I type in Wireless Security Key (WPA) on my Ipod it comes up as Incorrect password and I cannot log in

I have changed broadband providers - when I type in their Wireless Security Key (WPA) into my Ipod it comes up - INCORRECT PASSWORD - I know it is case sensitive I am putting in numbers and capitals but does not work. Is there another Password I should be using ???

I have recently upgraded to Mountain Lion thinking that it might solve the problem but it hasn't worked.
It's possible your current os has different keychain troubleshooting solutions. Try re-posting (copy paste) over in the OS X Mountain Lion forum area and do a Knowledge Base search.
Have you tried setting up a new account to see if your issue appears there? If you have Apple Care, give them a call or take your computer to the nearest Apple Store or an AASP as you are still under warranty.

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.

TS2756 How do i change my Mobile Hotspot Security from WPA to WEP?

I need help someone please

Well try WEP security on your router and connect the DSi to the network and see you you can connect the iphone to the network with WEP. I did find this https://discussions.apple.com/thread/1286293?start=0&tstart=0
I am not sure what you want to do has to do with personal hotpsot though

Wireless Lan using WPA 2 crypt is not working under windows

Hello,
is it a known problem that i can not connect to my WPA2 crypted WLAN ?
if i set up a non-cyrpted WLAN it works quite well, but not the WPA2 way.
Is there a workaround ,bugfix or whatever, or do i have to wait for newer drivers ?
Best regards
fidel

ok, problem is solved. thx again.
the only thing was really to get a windows/microsoft
patch for wpa2 support, which is linked in the wikipedia article.
(only available after succesful genuince check).
After that my crpyted wlan worked without problems
shame on me that i havent checked that before.
best regards

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!

Question connecting iphone 4s wifi using SSID and WEP where do I

Question, I am trying to connect my iphone 4s to a wireless router using SSID and WEP. I have entered the MAC Address on the phone into the Router's Security list.
I think that I also need to enter a code or passphrase on to the phone as well.
Does anyone know how this is done and where do I do it?
Thank you in advance.

Check the wireless security option of your Wi-Fi router:
If you are using WEP security and have multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key in key index 1.
Consider using WPA or WPA2 instead. WPA and WPA2 encryption protocols are newer, more effective security options for wireless networks than the older WEP protocol.

WRT54G Strange connection issue when wireless security is enabled

The model # is WRT54G v2.2 with firmware 4.21.1. I knew that my internet connection was good because I connected my laptop directly to the wireless antenna. When the antenna is connected to my wireless router I can't connect, wired or wireless. I decided to reset the router and program back in the changes that I have made. I checked for internet connection after the reset, it's there. Made more changes, still good. Then when I enabled wireless security using WEP the wired and wireless internet connection goes away. Any ideas to fix this. Can I go back to the previous version of firmware?

hi... go to ftp.linksys.com/pub/network and try downloading older firmware for the router and downgrade the firmware, after that reset the router back to factory default settings and reconfigure it...

Problems auto-connecting after sleep & startup (Changed from WPA to WEP)

Okay, I know there have been several issues similar to this, but after two days of sifting through posts, I still can't resolve this.
A few days ago I switched my AirPort network security from WPA to WEP-128. This was required to allow my Nintendo DS to connect to the netwrok, by the way. After the change, two similar, but slightly different problems started:
My 15" PowerBook G4 no longer auto-connects to the network at startup. The network is listed in the drop-down, and connects with no problem when I choose it manually. The computer seems to have no problem re-connecting after waking from sleep, which is odd because...
My other PowerBook, a 12" G4, won't auto-connect at startup AND won't re-connect after sleep. As above, it has no problem connecting using the Keychain once the network is selected from the drop-down.
So far I have tried, on both machines:
- trashing the system airport prefs
- deleting and resetting the network's keychain entry
- repairing the keychain (no errors found)
- turning off some unneeded power mgt options
- disconnecting USB peripherals
I have also reloaded the software on both my AirPort Extreme base and my AirPort Express hub, as well as restarting both hubs. I've also made sure that AirPort is at the top of the network connection list.
Both laptops are running 10.4.3 and have all the latest software updates installed.
What am I missing?
Thanks.

Both of these replies are helpful, in that they help confirm something I figured out this morning, almost accidentally.
One thing I didn't mention was that during the change from WPA to WEP I changed the network password. Now, I assumed that since the Keychain seemed to be working and I could get on the network manually without needing to enter the password each time, that meant the new password had correctly propagated throughout the system.
So, this morning I go into the Network settings, switch from Automatic to Preferred, select my network, look at the properties, and notice that somehow it has way too many bullets for that to be the correct password. I re-entered the password and that seems to have solved the problem. The new password I had entered somehow didn't make it into this setting. I guess trashing the network prefs, or renaming the network would have had the same effect.

WRT54GX2 Wireless Security Enabled DHCP blocked for wireless clients

Hey gang,
My subject says it all. Yesterday I updated my WRT54GX2 version 1's firmware to the latest and greatest.I first reset the box, and rebooted. I updated the firmware. On the first attempt I picked the wrong image file. The machine halted and told me bad image. I then found and installed the correct image. I then added an Admin password, and entered a new SSID. I left the DHCP settings at the default. I then set wireless security at WPA Personl/WPA2 with TKIP&AES.
I found the wired client could obtain an IP address and to connect to the internet. The wireless clients could connect, but could not obtain an IP address.
I left the wireless security settings off.
Any suggestions?

The wireless security settings are correct. The wireless clients "CONNECT" to the WRT54GX2. The clients stall on obtaining an IP address via DHCP. Fixing the clients with static IP addresses also does not work.
I repeat: The wireless clients successfully connect to the WRT54GX2. The WPA/WPA2 & TKIP/AES settings are correct. The clients cannot receive a dynamic IP address.
On Friday I will reset the box for 30+ seconds. I doubt this will have any effect. I reset it on Tuesday twice on Tuesday, and still have the problem.
Any help appreciated.

Can I use the Airport Express to create a secure wireless network in a wireless-only hotel?

Can I use the Airport Express to log onto an unsecured hotel wireless network, without an ethernet cable, to create a secure wireless network for my MacbookAir, IPad, IPhone, etc.? If so, how is that done?

will the Airport Express allow you to log onto a hotel wireless network, and broadcast a secure wireless network in your room for your wireless devices, like the Ipad, Iphone, etc.?
The bottom line with a single AirPort Express is no.
The AirPort Express can only "extend" a wireless network when the network is being provided by another Apple router.
As you might imagine, it is extremely unlikely that that the hotel network....which no doubt uses professional wireless access points provided by a manufacturer of commercial systems.....would be compatible with an AirPort Express.
In many years of travel domestically and internationally, I cannot recall a time when a single AirPort Express would "extend" the signal provided by a hotel's wireless network.
However, if you had two AirPort Express devices handy, you might be able to configure one to "join" the hotel network and provide an Ethernet signal to the second AirPort Express, which would be configured to "create" your own "private" wireless network.

Network security - using two wireless WRT54G Routers

I have lots of ports on my router open for numerous family software applications that are all on one computer and I would like to isolate these risky activities from the rest of my network.
I recently read I could use two routers, plug one router into another, assign each a different starting IP address (such as 192.168.1.1 and 192.168.2.1). Then attach my at-risk PCs--to the router that's directly connected to my broadband modem, and all other computers to the second router.
Internet traffic to and from the unsafe PC area would then not reach my secure subnetwork at all.
I currently use a WRT54G V5...does buying a second one and using it as described make sense? It sounds like a rather inexpensive way to add security to my network.
I assume the second router gets connected from it's internet jack to one of the port jacks on the first router? Is there anything else that would need to be changed or set in either router to make this work?
Can I please ask if u respond to try and keep your response at a level that a non expert could understand.....I would really appreciate it!
Thanks for everyones advice!

Thanks for the quick response....it is disappointing to see that I would lose the ability to share files......I assume this is also true for printers as well??? Do you have another solution that you think would do a better job?
Anyway I did get a rather detailed response on how to make it work and it's in a fashion that even I could understand.
I thought I would share it in case anyone else had a interest to isolate a computer.
Thanks
With regards to your concern, the setup that you suggested does address your concern. With this setup, we are somehow creating two networks on your location. In this manner, the computer that needs the set of ports will not be part of the network of the second router thus, it will not be able to affect the other computers.
With this type of setup, we will just have to leave the current settings of the WRT54G v5 (as long as its working properly this time). All we have to configure is the second router wherein we will have to change its LAN IP Address and also, configure its wireless settings in order for the said router to provide wired and wireless connection to all computers connecting to it. Please allow me to give you the steps.
Once we have the second router available, please connect one of the computers straight to the second router using one of the four ports (Ethernet port). With the configuration, only the second router and the computer will be connected with each other.
Before setting up the second router, I suggest that we do a hard reset on the router to make sure that it is on default settings and that we have a stable connection during the setup.
Here’s how to do a reset:
1. Locate the reset button of the router at the back panel.
2. Hold the reset button for 30 seconds using a pen or a paper clip.
3. Release the reset button.
Configuring the Second Router:
1. Go to your desktop and double click on Internet Explorer (Located on the Start Menu in Windows XP).
2. When "Internet Explorer" opens type 192.168.1.1 into the "Address" bar and click on Go.
3. The "Enter Network Password" window will appear.
4. Skip user name and type admin (admin is the default password) as the password, and click OK.
5. Go to Wireless Tab.
6. Change SSID (e.g. Vic or your name or last name).
7. Change channel to 11.
8. Hit save Settings.
9. Click on the sub tab Wireless Security.
10. Set the Security Mode to WEP.
Using pass phrase Encryption Level 40/64bit (10 hex digits):
1. Type a pass phrase.
2. Click Generate.
3. Copy key1 on a piece of paper (10hex character).
4. Hit Save Settings.
For using manual key entry Encryption Level 40/64bit (10 hex digits)
1. Under Key 1 type a 10 digit character from A-F and 0-9 (e.g.: A0B3F58C9E, 0123456789, ABCDEFABCD).
2. Hit Save Settings.
3. Click on the Setup Tab.
4. Change the Local IP Address to "192.168.2.1".
5. Click “Save Settings”.
Finishing the Connection:
1. Shut down all computers.
2. Unplug the power from the back of both routers.
3. Unplug the power from the modem.
4. Wait for 30 second.
5. Connect the WRT54G v5 router (using its Internet Port) to the Cable Modem.
6. Connect the WRT54G v5 (using one of the four Ethernet ports) to the second router (using its Internet/WAN port).
7. Power up the modem.
8. Wait for the lights to stop blinking.
9. Power up the routers.
10. Start up your computer.

Running WPA Wireless security w/ OSX 10.2

I am running an older G3 iBook on my wireless system and it does not seem to work with WPA wireless security. I am using a Netgear G614 router, which works fine except with the iBook. The iBook has no problem with the wireless security turned off and I would like to avoid using WEP, if possible. I posted this in the older OS sections with no response. Help!

I have a similar problem with which I've been struggling for months. My MacBook Pro suddenly stopped working with my home router - it showed as connected but would not browse.
I have eventually boiled it down to a problem with WPA security. Ethernet networking works, networking with WEP security and no security works, but WPA doesn't. This applies to any router, not just mine at home.
When it originally failed, my MacBook was running OS X 10.4.11. Rolling back to 10.4.9 and before removes the error, but 10.4.10, 10.4.11, 10.5.1 and 10.5.2 all exhibit this failure. The fault is not evident on my iMac G5 or my new iMac Intel, or on my daughter's XP PC.
Therefore, it is a combination of hardware and software issues. So don't expect a cure just by upgrading!
Does anyone have any ideas for a cure, please?

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.
