WPA and WEP

Hello,
can anybody tell me if its possible to use both WPA and WEP security access on the same SSID.
And can anybody point me out to some references for follow reading.
Thanks
Mark

According to the documentation I have been able to find it is possible. See conversation titled Reality Check ... about 10 lines down from this one. The article includes links to the docs. I cannot get it to work, however. I can get my WPA clients to connect but I lose my original WEP clients. If you find a solution please pass it on.

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.

Satellite M30-107: WPA and WEP security software

I wish to connect my Satellite M30-107 P-M 745 to an up-to-date MIMO G+ wifi network.
I have bought a router and PCMCIA adapter card.
I wish to set-up WPA and WEP security - do I need any special Toshiba software on the PC itself to do this, or do I just use the software that came with the Router and adapter card?
Thanks

Hi
First of all you cannot both Wlan encryption WPA and WEP together.
You can use either WPA or WEP. I would recommend using WPA because its safer.
I agree with Barrie. If you want to use one of this encryption you should be sure that the WLan card and the router support this features.
In my knowledge most of the newer Wlan routers supports WEP and WPA. In this case you have only check the WLan card if the option is available or not.
By the way: You don't need any special software to set the encryptions.
You can set the encryptions also in the Windows own WLan configuration area.

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!

WPA vs WEP

I have two AEBS interconnected by ethernet. One is the router, the other is an access point at the other end of the house. Both had been set to WPA.
We have been having problems with web pages stalling during loading, a reload would often bring them up instantly. The I reset one of them to WEP so my son could do net games with his DS. After a while, we dermined that when we connect to the one set to WEP (they have different SSIDs so that we can tell them apart) didn't have this problem and the one set to WPA did. I reset both to WEP and now the "problem" is gone.
Anybody else notice such a difference?

The base stations have different names as well as different SSID's. They used to work perfectly together until I increased the security level to WPA.
One is on channel 11, the other on channel 1. The cable modem is connected to one of them (the WEP station) and it provides NAT services. The other is on the other end of the internal wired LAN and provides wireless access and has a connected printer.
We see two different names in the airport list so we can pick the one that we want to use. Roaming is not an issue as both stations cover the whole house to some extent. If we switch from one to the other, some network services, such as iChat, disconnect and reconnect. Apple file services still work if the server or client switches during a connection.
File services go 2x faster when the two computers involved use different APs because the AP doesn't have to share the RF bandwidth with two computers. When one is acting up (as they were when new because I had a series of defective hardware) it was much easier to tell which one was acting up when the SSIDs were different. I just left it that way after the hardware stabilized.
This issue isn't an "every time" type of thing. We notice it in aggragrate over time. Usually, when one site is not loading properly, ALL sites don't load properly. When one is working well, all work well. Download rates, once connected to a good site, are identical for both at 624kbytes/sec (limited by the cable modem). Both stations are AEBS, one has a modem, one does not.
When the WPA BS is stalling, the WEP BS is working fine. I've tried switching the WPA and WEP settings. The problem follows the settings.
When a site, or set of sites, "stalls", the network data rate as indicated by the Activity Monitor, drops to zero. Other computers using the WEP BS at the same time continue to work.
I am guessing that something is happening to the rotating keys and the router is loosing the connection between a service request and the computer that requested the service. It takes a kick in the backside, by reloading a page, to establish a good connection. The stalled connections do not seem to fix themselves ever.

Problem with radius and wep/wpa

Hi
I have problem with wrv200 (1.0.38) +freeradius (2.0.5) +wpc54g v3.1 with wxp with patch to use wpa/wpa2
I think that authentication in my radius pass correct but there is some problem with wpa mode or wpa compatibility
In my wrv200 I try mode: wpa-enterprise, wpa2-enterprise, wpa2 enterpise-mix and radius. In my wirless card a try: wpa and wpa2 my
freeradius.conf:
andy Auth-Type := Accept, User-Password == "andy"
and log from radius:
rad_check_password: Auth-Type = Accept, accepting the user Login OK: [andy] (from client wrv200 port 0 cli 00-18-F8-aa-aa-aa)
Sending Access-Accept of id 4 to 10.0.0.6 port 1026
my wrv200 still send to syslog:
klogd: @ = Add Host : [00:18:f8:aa:aa:aa] VID 9 LinkID 1 PortNumber 6 klogd: @ = Add Host : [00:18:f8:aa:aa:aa] VID 9 LinkID 1 PortNumber 6
klogd: @ = Add Host : [00:18:f8:aa:aa:aa] VID 9 LinkID 1 PortNumber 6
and i never connect to network and i must still (every 30s) type login and password to authenticate When i use only wep, without radius,it's works
I have dwl900ap+ from dlink and when I use radius + wep 64bit everything works
i don't have any idea
thanks for any help

Hey try disabling the security & try connecting to the network if it works fine, if not i mean if you want to connect using the secured network then would suggest you to upgrade the firmware of the router & keep on holding tightly
the reset button in such a way that power light is blinking on the
router & then do a complete network power cycle i.e., unplug the power
cables from the modem & from the router & then plug in the power cable
to the modem first once all the lights are solid green you could plug
in the power cable to the router & check out it will definately work!!

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.

Difference between WEP, WPA, and WPA2 and better suggestion to use for shared family users

What is the difference between WEP, WPA, and WPA2? My router is set up on my family PC and connected to a modem so I access Wi-fi through my laptop and my sister has a laptop too and uses our family network to get internet. I just set up a WPA today, so will we all be able to get internet (along with my family using the pc, and my sis on her laptop, even at the same time) protected? (like nobody else using our network)

Wired Equivalent Privacy, commonly called WEP is 802.11's first hardware form of security where both the WAP and the user are configured with an encryption key of either 64 bits or 128 bits in HEX. So when the user attempts to authenticate, the AP issues a random challenge. The user then returns the challenge, encrypted with the key. The AP decrypts this challenge and if it matches the original the client is authenticated. The problem with WEP is that the key is static, which means with a little time and the right tool a hacker could use reverse-engineering to derive the encryption key. It is important to note that this process does affect the transmission speed.
WPA builds upon WEP, making it more secure by adding extra security algorithms and mechanisms to fight intrusion.
WiFi Protected Access (WPA) is the new security standard adopted by the WiFi Alliance consortium. WiFi compliance ensures interoperability between different manufacturer’s equipment.WPA delivers a level of security way beyond anything that WEP can offer, bridges the gap between WEP and 802.11i networks, and has the advantage that the firmware in older equipment may be upgradeable.
WPA2 is based upon the Institute for Electrical and Electronics Engineers’ (IEEE) 802.11i amendment to the 802.11 standard, which was ratified on July 29, 2004. The primary difference between WPA and WPA2 is that WPA2 uses a more advanced encryption technique called AES (Advanced Encryption Standard), allowing for compliance with FIPS140-2 government security requirements.

Problem with wpa and hidden ssid

hi,
I have a powerbook g4 (1,67ghz). i am having trouble connecting to a netgear router mr814 v3 if i use wpa and hidden ssid, i get a message, that the router would not support wpa!
there is no problem with wep and hidden ssid or wpa with no hidden ssid.
is also have no problems with wpa and hidden ssid with an ibook.
the problems occur only with the powerbook with os x 10.3.9 as well as 10.4.2. even after the recent airport update, no change.
thanks for the help,
ben

I would use WPA and broadcast your SSID.
It use to be useful, but closing your Airport or wireless network (sometimes referred to as not broadcasting your SSID) is really no longer a real option when it comes to wireless security.
Unfortunately "Closed" networks, MAC access control lists, and reduction in transmission power are all more "feel good" security rather than real security. All these various approaches are dated and mistakenly lead to overconfidence.
WPA is your friend if you value wireless security.
My recommendation is not to worry about broadcasting your SSID but use WPA. This will be more secure than a closed WEP encrypted network. Closing your network makes it very difficult for neighbouring networks to see which channels are free thus causing potential interference problems.
Another thing to consider is that a closed network is still broadcasting and therefore is detectable (regardless of whether it is broadcasting a SSID). If someone was determined to hack into your network, then not broadcasting your SSID and MAC address access control is not going to stop them.
WPA is virtually uncrackable (only really vunerable to a dictionary attack if a real word is used as a password) and therefore will stop the casual user and the determined hacker.

HT1178 What the difference is between WPA and WPA2 and how are these settings affecting the access of other computers to the internet through my Time Capsule

I have a Time Capsule of the 4th generation and I am pretty impressed since I just had a fried harddrive on my 3 month old Imac and Time Capsule restored it fully including all programs etc. without having me to put in all serial numbers etc. for that I give it an A+. However what I find very frustrating is the very short and incomplete user manual and setup instructions. I give those a D-. It does not explain the consequences of certain choices to a normel non computer gig user like me:
I do not understand what the consequences and difference is between the security setting WPA/WPA2 and WPA2 when setting it up. It would be helpful if the manual would explain something like: If you set it onto WPA2 then computers older than XXX years will not able to hook up to the internet through your router...or the likes, since I slowly supect this may be the reason for some of my troubles.
I also have a 5 year old PC with vista connected to the Time Capsule. It can wireless connect to the Time Capsule and access the printer (I have managed that after some painful hours...) but it cannot access the internet with that PC through the timecapsule wireless, only if I hook it up with a cable. Why? Does that have to do with the fact that I have set the TIme Capsule to WPA2?
Our PS3 can connect wireless, no problem. However, I friend of mine tried it with a quite new Toshiba Notebook and he could see the Time Capsule but again it shows the line from the Time Capsule to the internet blocked. All other computers linked with data cable to the Time Capsule are connected to the internet no problem. What have we done wrong? Should I change the security setting to WPA/WPA2?
I tried the latter, but then another problem does come up, which was there from beginning on: When I change the settings for my Time Capsule my Imac suddenly cannot find the Timne Capsule anymore, even so I am only 3feet away from it. When I set it up for the first time 3 month ago it drove me crazy. The very first time it found the Time Capsule right away. But when I discuverd a mistake in my initial setup and I went through the settings again to change stuff it suddenly could not find the Time Capsule anymore. Only after frustrating 20 times or so with turning wi-fi on and off several times inbetween did it suddenly find the Time Capsule in the set up menu. However, when I tried changing my security setting to WPA/WPA2 today to see whether this solves my other problems again it could not find the Time Capsule when I was finished with the settings and I had to give up/cancel. Why is that???
I would really appreciate some help here. But please I am not a computer gig and normally always had assistance with these things. On the other hand I am not all stupid either (even so these manuals assuming we all grew up sleeping on a computer make me feel stupid).....
Thank you all in advance

Hello Schimi. The Time Capsule is a kind of product that offer you two possibility:
- To use the TC as a router or as an external HD.
The difference between WPA and WPA 2 are:
- They are two kinds of internet connection.
WPA uses dynamic key encryption , which means that the key is constantly changing and makes the invasion of a wireless network more difficult than WEP . WPA is considered one of the highest levels of wireless security for your network and is recommended if your devices support this kind of encryption . Newer routers offer WPA2 security . WPA2 is compatible with WPA , but offers higher security level . In fact, it meets the high standards of many government agencies . If the router and computer support WPA2 , this should be your choice.
If you need any help or if you find some difficult setting up it you can contact Apple Support.
I am sure that they can help you with that.
I am sory for the delay. I holpe that you solve your issue.

What's the security difference between WPA and WPA2 Personal?

In order to get my G4 iMac (OS 10.4.11) onto my new AEBS(b/g/n) wi-fi network, I had to drop the network security down from WPA2 Personal to WPA/WPA2 Personal.
What are the potential security risks in this mode? I know that WEP is no longer secure, so I'm concerned about WPA also being vulnerable.
If there's a good online explanation of these security differences (not necessarily Apple-only), you just give me that link.
Thanks

Hi,
Summary:
1.WPA2 is the improved version of WPA
2.WPA only supports TKIP encryption while WPA2 supports AES
3.Theoretically, WPA2 is not hackable while WPA is
4.WPA2 requires more processing power than WPA

Macbook Pro and WEP problem

Hello guys,
Ive been looking for a solution to this problem for a long time. I have seen various variations of my problem but nothing exactly the same. But still I appologise in advance if this has already been covered.
Basically I bought a MacBook Pro back in late November and for some reason I cant connect to any network that has a WEP password. I had one on my home network and had to remove it leaving the connection open in order for me to connect. but now I am on holiday and I am having the same problem. I have the right password and everything but it just wont connect to it. I get a message saying "cannot connect to <network name>"...its quite frustrating.
What could be wrong? Any help would be greatly appreciated, or if you can just point me in the right direction that would be cool too
Thanks guys
Ross

My MacBook Pro had been working fine with my WEP encrypted wireless router until my husband "fixed" the router to work with his lame XP laptop. He reset the router and reinstalled it, then I could not connect unless it was set to WPA, and he couldn't connect until it was set to WEP. I finally figured out how to connect using the WEP. I have to open Internet Connection and instead of selecting my wireless network from the list, I have to select 'other', and then select my home network. Then I have the option to select WEP hex instead of WEP password. My password then works. I don't have to put a $ in front of it.
Now I have the problem of having to do this each time I turn on the MacBook, though. Does anyone know a way to change the default encryption for a wireless network so I don't have to go through this each time? I tried changing the preferred network settings, but, again, when I pick the home network from the list it does not recognize my password because it thinks that it is WEP password instead of WEP hex.

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.

E4200 Wireless Guest and WEP connects, other security settings do not

I have E4200 with fixed ip 192.168.1.2, DHCP off connected through LAN ports to FIOS ActionTec as 192.168.1.1. When connecting through wireless network off the E4200, I can obtain and connect fine under Guest network and WEP security, but for any other security setting, WPA, WPA2, Mixed mode, etc. I get the message "Aquiring network address" forever, and I never get a connection. How do I troubleshoot?

Is your FIOS ActionTec wired or wireless modem/router…. From where you are receiving the wireless signals to connect… Which operating System that you are running on the computer? It happens only to a specific computer or it happens to all the computers connected in the network?

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.

cactus wrote:
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
