WEP and WPA?

I have some old and new laptops. The new ones can use WPA but the older ones seem to only support WEP. Is it possible to configure my router (WRT54GS) to use both WEP and WPA?
Thanks

No. Your WRT54GS cannot do WEP and WPA at the same time.
Check and see if there is an updated driver for your old wireless adapter, that will allow it to do WPA. If not, the best solution to your problem is to replace your wireless adapter with one that can do WPA and WPA2.
Another work around solution is a two router solution:
Modem -- WRT54GS #1 -- WRT54GS #2
WEP WPA
192.168.1.1 192.168.2.1
(Note: LAN port on WRT54GS #1 is wired to Internet port on WRT54GS #2.)
The problem with this solution is that the computers on #1 will not be able to access anything (computers, printers, etc.) that is connected to #2

Mixture of WEP and WPA on wireless network

I have a WRT54G and a cable modem. The router is configured to use WPA. I have many personal wireless devices (print servers, computers, access points, etc.) on my network. All are configured to use WPA. My wife and I just got company-issued laptops from our employer that have software that does not support WPA (we can't change the software). The laptops only support WEP. Is there a way to run a mixture of WEP and WPA on a wireless network? If I have to buy an additional router, that is OK. I'm looking for a solution that will allow me to run both WPA and WEP over the same internet connection.
Would MAC filtering on my current router be a possible solution?

It is not possible to use WEP & WPA at a same time in a router .....
But you can enable the MAC flitering on the router for all wireless devices ..... let me know if it works ....

AP Power difference between WEP and WPA

Can someone tell me what to look for? I have two SSIDs on an AP: one is WEP and the other is WPA.
I have 5 bars on WEP ssid, but only 2 on the WPA side and eventually down to one.
Thanks,
John

Hi John,
Actually your are getting the same signal from both SSID's.
The reason that your are getting 5 bars in one and 2 in the other depands on the OS wireless uitlity.
If you will use a wireless sniffer you could see the RSSI reading in the frame header.
Cheers.

Configuring WEP and WPA on 1262 AP

This seems like it should be quite simple. We're in the process of migrating users from WEP over to WPA. In the transition we'd like to make both SSID's available until the old WEP is phased out. I have found that both can be broadcasted on the same frequency as long as VLAN's are used. For simplicity purposes, I have configured VLAN1(WPA) and VLAN2(WEP). VLAN1 is the native VLAN, and when connecting there I receive a DHCP address no problem. However, connections to the WEP SSID will not resolve an address.
I've also read that I can switch my uplink port on the Switch to a Trunk port and route those VLAN's, however, I really don't want to introduce new VLAN's into our entire core structure. Is there any way to just make VLAN1 and VLAN2 able to both work properly in this scenario?

Well that is the right idea I think but my setup is a little more complicated than that. So there is absolutely no way to do this without those VLAN's going past the AP? I really do not want to introduce any new VLANs into my environment right now. I would thing there would be a way to "bridge" the interfaces so that they both work the same, even though they are VLAN'ed.
Also, in my configuration, I'm using WEP on Radio0 and WPA on Radio0 and Radio1, so it's a bit more challenging than the configuration provided. Can anyone confirm or deny that there is no way to do this without broadcasting those VLAN's throughout the network?

Coexistance WEP and WPA

I try to configure 2 ssid's for 1131 autonomous AP. One SSID with open authentication and WEP encryption and the other SSID using WPA. The "WEP-SSID" is in guest-mode. So i can see the "WEP-SSID" in the list of available W-Lans on a notebook but WPA protected and not WEP protected. An other issue is the unability to get a IP address from a DHCP server for wireless stations using the "WEP-SSID"-network. Any ideas for these behavior ?

Make sure the DHCP server is in the same subnet as wireless client. If it is in the different subnet, ensure that reachability is there between these devices. Send me the debug ip dhcp enable command and send me the debug output.

WEP or WPA security

D-Link DI-624 offers either mode. The WEP mode is easier to understand and relatively painless for setting up under 64-bit passwords. Do 128-bit passwords offer a much greater level of security? (The network is home based, in a small town.)
Should I consider the WPA mode? How much more difficult is the utilization of WPA mode?
Thanks.

I don't know about the setup process with a D-Link wireless router but the following was copied from AirPort for Mac OS X 10.3 or later: Using different types of wireless security (WEP and WPA).
WPA is a very secure encryption method that is now preferred for computers that can use it. WEP is an older encryption method that is less secure, but it is useful if your network has systems that are not WPA capable.
In addition to being much more secure, WPA is also easier to use. WPA works best in Mac OS X 10.3.3 or later with AirPort software 3.3 or later.
There are two ways to set up WPA, Personal and Enterprise. WPA Personal is easier to set up if you have a small network, such as in your home.

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.

What is the WEP or WPA password, and where can I find it?

I just bought an HP dv9013cl with wireless 802.11a/b/g and I am able to connect to my airport, but after it asks for a WEP or WPA password. What is this password and where can I find it. Thanks for the help.
Halfpiper900

Goto Airport Admin Utility, click on CONFIGURE. At the top of the screen that opens, click on PASSWORD, you'll see what looks like a lock. A drop down screen will show the Hex WEP password.

Wep key and wpa does not work.

I'm trying to set up security for my router using wep or wpa but everytime I set it up, my key does not work. The router is suddenly disabled. I did exactly as the how to setup wireless security said. do u have to hard reset to get it to work. I've been trying to set security for three days. Your help is appreciated.

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.
For WEP, you must enter WEP "key 1" (found in the router) into your computer, not the WEP password or passphrase.
For WPA or WPA2, enter the key (sometimes called password or passphrase) into your computer.
Note that for WPA or WPA2, use "personal", not "enterprise".
Also, nomenclature sometimes causes problems. Note the following:
WPA = WPA with TKIP = PSK
WPA2 = WPA with AES = PSK2
Also note that Windows XP requires SP3 to run WPA2 ( = WPA with AES).
Also, each time you try a new encryption method, you must remove old settings from your computer. To do this, do the following:
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. Delete your current network (this will remove any old settings). Reboot computer. Return to "Preferred Networks" and re-enter your current network 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". Reboot computer. You should connect automatically (it can take up to two minutes). If you still have trouble, in the computer, temporarily turn off your computer software firewall, and see if that helps.
If the above does not fix your problem, download and install the latest driver for your wireless card.

7920 - Firmware Version that support WEP, LEAP and WPA

Hi Guys,
My Customer have the CallManager version 4.1.3. He have the IP Phone 7920 and need use WEP, LEAP and WPA. Anybody tell me if version cmterm_7920.4.0-03-02 support this protocolos?
Thank You,
Wilson

LEAP uses WEP 40 or 128 bit encryption
WPA (or WPA-PSK) uses TKIP
You can only define one encryption type per radio interface so that is why both won't work simultaneously...
With multiple vlans setup, you can now assign encryption on a per vlan/ssid basis.

WiFi problems after changing from WEP to WPA on Actiontec router

I need some help/advice--I've searched the forums but am not seeing my exact problem described so decided to describe it to see if the community can help me figure out what to do now. The situation is this: After recently learning about the insecurity of WEP "security" I decided to change the security settings on our Fios router (an Actiontec MI424WR, Rev C). I first tried to change the settings to WPA2, but then my husband's elderly Dell laptop could not connect, so I changed them to WPA. At first everything seemed fine--we could connect to the internet from our computers (my MacBook Pro, his Dell, and various devices--phones, kindle, iPad).
But we soon noticed some strange problems that I was never able to resolve:
I could never get either of two Airport Expresses to connect to the network, even after repeated tries (with hard resets in between)
Within an hour or two after rebooting the router, I was no longer able to connect wirelessly to a NAS device that is connected to the router via an ethernet cable--I could no longer even see it in the Mac finder. I could see it in Windows Explorer from the Dell but could not connect.
Similarly, I lost contact with a Sonos bridge unit that is also connected to the router via an ethernet cable. In this case the loss of contact was sporadic--various devices that connect over WiFi to the bridge could sometimes see it, sometimes not.
Resetting the router would temporarily restore wireless access to the devices hardwired to the router, but I would always lose the NAS device completely after an hour or two and the Sonos bridge sporadically. The computers and devices, however, had no problems connecting to the router itself and from there to the internet.
I finally gave up and returned the security to WEP, and now everything is fine: the Airport Expresses connect, the NAS remains available, and the connection to the Sonos bridge over WiFi is robust (the Sonosnet mesh, if anyone is wondering, was never affected).
I can't understand why switching to WPA caused such problems, but it clearly did, since switching back to WEP eliminated them completely. The simplest explanation is that there is some problem with the wifi portion of the rev C router that only becomes apparent in certain circumstances, though it seems weird that both wired peripherals and wireless airport expresses were affected.
Whatever the causes of the problem, now I'm back to wondering how to improve the security of my network. Should I:
See if I can convince Verizon to replace the modem with a newer version? We have had this one for more than 4 years, since we first got fios.
Just go ahead and purchase the most recent version of the Actiontec router (rev G)? It's only about $115--worth it to me if I can use WPA with it.
Buy our own wireless router, perhaps an Airport Extreme, and turn off the wireless on the Actiontec.
Thanks in advance for any help. This is driving me crazy, and I really don't like feeling as if the network is vulnerable, especially given how extensively we use it.
Becky

This doesn't sound too uncommon. I had similar issues in the past with some networks I've worked with that were resolved by moving the router actually to WPA2 or by updating the firmware. The ActionTec MI424WR Rev. F, G, and I require the use of WPA2 since they have Wireless N radios in them so WPA wouldn't be of much use. My old Linksys WRT54GX also had similar issues, but that was a result of the Wireless Radio dying along with a mix of newer hardware not playing nice with the old, no-longer-supported firmware. I retired that router, only to bring it back into service as a Wired router at a friend's home (shutting off Wireless and setting up another as an AP) which replaced an old BEFSX41 which didn't have enough power to handle his Cable connection.
Besides a few software bugs at play somewhere, there isn't much that could cause the wireless to slowly stop working like that. I would suggest moving back to WPA2. For the older Dell laptop if it's running Windows XP, make sure at least Service Pack 3 is installed if it hasn't been getting updated. Also, check for updated drivers for the Wireless card since they may be needed as well. A bit of searching on the Wireless card should also indicate whether or not it supports WPA2 encryption. Anything from the mid-2000s should support it.

[solved] wicd do not work with wep or wpa/2...

Hi!
I have configured wicd using the wiki, and checked the steps several times... but only works when the wifi router is set to no encryption...
If I use wep or wpa wpa2 it just keeps handshaking and never connects...
any idea?

Problems with AirPort and WPA access point

Okay, I have done quite a bit of research and I still cannot resolve my problem because of this, I am turning to this user community.
Here is what I know as of right now:
I am running Windows OS X 10.4.4 with AirPort Update 2005-001. My Access Point is a 3COM 8250.
The AP is setup not to broadcast its SSID, to use WPA-TKIP (or in Apple terminology, WPA Personal) and the password is set to use alphanumeric.
When I try to connect my PowerBook with the SSID name, WPA Personal and the correct password, I get the following error:
The password you entered is not correct for the Airport network *******.
To troubleshoot here are the test I have run and their outcomes:
Test
- Result
Set the AP to completely open
- Connected
Set the AP to open, didn't broadcast the SSID
- Connected
Set the AP to WEP, broadcast the SSID
- Connected
Set the AP to WEP, didn't broadcast the SSID
- Connected
Set the AP to WPA & WEP, broadcast the SSID
- WEP : Connected
- WPA : Not Connected
Set the AP to WPA & WEP, didn't broadcast SSID
- WEP:Connected
- WPA:Not Connected
Set the AP to WPA only
- Not Connected.
Now, I should mention that when I was running 10.3.3 I could not connect either. The AP is running the newest firmware and I have three Windows XP SP2 laptops / workstations that can connect with no problems.
I have tried to find a compatibility matrix on both 3COM's and Apple's websites to see if it might be a compatibility issue but I have not been able to find one on either site.
Any help that anyone could provide would be greatly appreciate.
Thanks in advance.

Hello MisssAsh. Welcome to the Apple Discussions!
It's always a good idea to do a complete power recycle when changing network configurations.
Try the following, in order, checking for Internet access after each step, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AirPort Express Base Station (AX), & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

What is the WEP or WPA password?

I have a friend from out of the country trying to use my airport internet connection and he can not sign on because his computer keeps asking for the WEP or WPA key code. I do not know what this is or where I can find it. Can anyone direct me to where I can find this password?? By the way he is running a Windows XP computer, mine is a MAC.
thanks,
Ralimage

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.
