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 step by step instructions for wireless security setup on my westell modem

    I tried setting up security shortly after getting the modem, but I had trouble getting vista laptop to work with the security settings. I don't feel like figuring this all out. I would like step by step instructions for my modem. It is the Westell VersaLink 327W. If these instructions are on a web site somewhere that would be great.
    Thanks.

    I think I just answered my own question. I exported to my desktop and then added it to my iDisk.
    If anyone has any other tips, that would be great. Not sure how to set up the size of the frames.

  • 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

  • My Telus wireless only works with WEP, but if I switch to WEP the wireless goes down on the other Windows computer being used in the same house.  Is there a way for both of us to get wireless internet or do one of us have to be connected by the ethernet?

    My Telus wireless only works with WEP, but if I switch to WEP, the wireless on the other computers in the house (which is Windows and WPA) stops working. My computer works with the ethernet cord but I want to be wireless too!  Do one of us have to sacrifice our wireless?

  • I have a hp deskjet 3050 all-in-one printer how can i setup for wireless printing my os is windows7.

    how do i setup my hp deskjet 3050 all-in-one printer for wireless printing my operating system is windows7

    Unplug the USB cable.  Now go to Start > All Programs > Hewlett-Packard > Deskjet 3050 > Add a Device.  Run the program and choose Wireless as the installation type.
    Follow the directions.  It will ask you to connect a USB cable temporarily.  Do not connect until it asks and remove it when it tells you.
    Finally, when you are done, go to Control Panel > Devices & Printers and delete the USB instance of the printer so you don't get confused when printing.

  • How to setup Time Capsule for wireless backup only

    I have a new Time Capsule that I want to set up for wireless backups of both my Macbook Air (with Time Machine) and a Windows Vista laptop. I have an existing home wireless network with my Att/Uverse tv and internet service. I do not want to disturb that network/internet setup.
    How do I set up the time capsule to use it for wireless backup only? When I start the Airport utility setup, the first thing it asks is do I want to 1) set up new network, 2) replace existing router, or 3) join existing network.

    Thanks. That got me the green light and a message that everything was set up properly. It started it's first Time Machine backup and everything looked good for a while. But now I have a new problem.
    The backup failed twice. The first time it had a message that it could no longer find the time capsule, so I had to reset it and go thru the setup procedures again. Started backup again overnight, and this morning it tells me that it failed again. But this time I still have my green light, and the message is "a network problem may have interfered with the backup.
    I don't know what else to do with the setup to get it to work. Right now it has started backing up again on its own, so I'll leave it going one more time. (I should tell you that all of this is occurring on my Mac. I have not even started setting it up on the Vista machine. I want to make sure it works on the Mac first). Any advice from anyone who had the same problems with setup would be appreciated.

  • DMZ Anchor WLC setup for Wireless Guest Access

    I have the following setup.
    A DMZ WLC 4402 connected to firewall DMZ interface in 10.10.73.0/24 network.
    An Inside WLC 2106 connected to firewall Inside interface in 10.10.71.0/24 network.
    Both WLCs are running the same 4.2.176 code.
    DMZ WLC is anchor to itself and Inside WLC select the DMZ WLC as the anchor point.
    I have setup EoIP between DMZ and Inside WLCs successfully with both the control and data path both show as UP status. >> "show mobility anchor"
    The main issue: Clients cannot obtain IP addresses after connected to Guest SSID.
    1. Inside WLC, the guest WLAN ingress is 802.11b/g radio and egress port is set to management interface (EoIP) of type WLAN.
    What is the DMZ WLC setting? Is the ingress set to "802.11b/g" which does not make sense because the ingress is EoIP from Inside WLC?
    Or I still set as 802.11b/g? Same config as Inside WLC? I read from other threads suggested by Terry that the config must be the same for both WLCs.
    In the Inside WLC, I saw alot of pdu encapsulation errors for broadcast packets which is ffff.ffff.ffff xxxx which I think is the DHCP request from the connected Wireless clients not making through the EoIP tunnel. I have set static ip for the Wireless client but the packets cannot route through the EoIP tunnel to the far end.
    2. DHCP server is provided by DMZ WLC with the scope 10.10.76.0/24. In the Inside WLC, which DHCP server IP adddress to set to? DMZ WLC mgmt ip address? DMZ WLC, the DHCP server is also set to DMZ WLC mgmt ip?
    3. Layer 2 authentication. I read that DMZ WLC is supposed to be the DHCP server, Layer 2 or 3 authentication for Wireless Clients. However, it seems like Inside WLC is required to configure the Layer 2 authentication parameters and the DMZ WLC is set to providing the DHCP service?
    4. Lastly, anyone has done DMZ WLC sending the Wireless clients traffic to Bluecoat proxy server before hitting the Internet?
    Thanks.

    One of the biggest things is to make sure the wlan is configured exactly the same. The DMZ WLC ingress is the management and also is the egress port. You can create a dynamic interface on the DMZ WLC, but this way makes thing easier. The DMZ WLC should provide the dhcp, so the dhcp scope of course will be on the same subnet as the management of the DMZ WLC. The DHCP Server will be the ip address of the management interface of the DMZ WLC. The authentication also has to be configured exactly the same on the inside wlc and the DMZ wlc. Since you are pushing clients through the tunnel to the DMZ WLC, that is where clients will need to get their ip address, since that DMZ WLC has a network interface to the guest network. I haven't had luck when a proxy is involved, but I know there was a post a while ago on how to setup the proxy to allow the wlc to bypass the users initial dns resolution.

  • Restrictions ACL for Wireless AP to WLC in HREAP Desgin Setup

                       Hello, Everyone  I have Wireless HREAP setup in which the Wireless LAN Controllers (WLC) are located across the WAN in DataCenter while the Wireless Access Points (AP) are located within the branches, so setup is fine but as security requirement mandates that the APs VLAN in the branch should be restricted from accessing any thing except neccessary communication to WLC across the WAN so on the interface VLAN assigned for the APs in the branch i Applied an inbound ACL as below and it works fine but after some times my be days i found that the Access points are not present in the WLC GUI and it will appear only if i removed the ACL...............So question here what else is missing in my ACL which is neccessary for AP communication to WLC?

    Thanks Amjad Abdullah and sorry for late reply i was on sick leave
    Actually the issue was due to the ACL, which was blocking the DHCP (how stupidly I overlooked that)
    I have did the same command as you instructed and it reveal that AP has timed out, so I have enabled debugging on ACL to see what kindly of communication is going on and I found many communication which I was keep allowing it based try and error till I found this log that Some APs IP address are trying to communicate to the default VLAN gateway IP address on port 67 which is DHCP then I realized this is the issue.....
    In brief....the APs are assigned to a dynamic VLAN (DHCP-enabled) so when I apply the old ACL, the APs already has obtained an IP addresses and they work fine with WLC, but when the DHCP lease timer expires, the APs try to send DHCP renew to the default gateway in which no ACE inside the ACL is matching so that request being denied and therefore doesn't get an IP address so it loses communication with the WLC....
    So I added the following ACE at the end of the above ACL
    permit udp host 0.0.0.0 any eq bootps
    NowI will always remember.......Security comes with cost

  • HELP regarding making password work for wireless setup. should be easy...

    Hi. i have read and tried everything. I am using a Linksys BEFW11S4 wireless access point router. Firmware version 1.44.2. i am trying to set it up so if someone wants to wirelessly use the internet (laptops, etc), they would need a password. should be simple, but its being frustrating...
    i have tried to set the WEP to mandatory and set the passphrase to something and then when i try it out on my mac laptop, it doesnt work. i also tried doing line 1 of the key codes it generates and that didnt work either. this is per instructions.
    i would grealy appreciate if someone could help me in this problem. i just want to be able to secure my wireless network so the only people in the apartment building that can use our internet would be me and my roommate on our laptops. thanks.

    hi gizzy, what i ended up doing was making it 128 bit under wep and it gave me a code which was pretty long. then when using my mac, for wireless type on the network i chose 128 bit hex. i typed in the code that was generated for me and it ended up working to make my wireless secure. unfortunately its not some easy password i can remember, but it worked. i just had to write it down. let me know if this works for you. also, if there is anyone else out there who knows how i can make it an easy password that i can remember and have it work, please let me know.

  • Setting up security and such for wireless router wrt54g without admin rights (work computer)

    We are moving, I am in a new location with a new company and my only computer is this one from work. Trying to get my home network setup, I'm locked out of admin rights on this thing and am trying to set up the above router. I thought I had a modem problem at first, but finally I am online wired for now to the cable modem. I would like to get this router up and running, but I can't use the easy setup disk, and I just tried using the easy setup download and it is locked out as well. How can I get my router setup with security, with no admin rights on the pc?
    This will be my first wireless router, so I am very green on the specifics and terminology. Any help is most appreciated.
    Many thanks,

    Thank you toomanydonuts!
    I will do this when I get back to the townhouse this evening.
    Just so that I am prepared for tonight - I want to confirm and ask a few questions on the "options" and note a couple things I noticed that may help with answers...
    Internet connection type - should be easy, I assume there is a "cable modem" option.
    SSID - I do not know what this means or what to choose
    wireless encryption method (WEP, WPA, WPA2) - Which is best, or is there one I must pick due to computer used and such, I also want to get my Nintendo Wii accessing correctly, I saw these options on that setup, though it didn't work per my first message on the board. I assume whatever encryption method used needs to be chosen for the Wii?
    wireless encryption password - I think I can handle this one
    A couple of notes -
    this laptop has this always on radar looking for wireless connections - how can I name my router so I know it's mine, other than the fact that it is the strongest signal. Maybe that's a network setting?
    Thanks again, glad I came here.
    Edit: I suppose I should add, just to ensure - in order to do this process through the url provided above, I need to be ethernet wired through the router to the modem? in order to access last night, I was straight into the modem, didn't seem to work wired through the router.

  • 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.

  • [SOLVED] wireless network setup

    Hi!
    I've been trying to setup a wireless connection, unfortunately without success.
    So.. my wireless card is a Broadcom BCM4301 802.11b, so I followed the wiki
    http://wiki.archlinux.org/index.php/Wireless_Setup
    to check for the module and install it (bcm43xx), specially the section
    http://wiki.archlinux.org/index.php/Wir … up#BCM43XX
    Then I created a network profile:
    # Network Profile
    DESCRIPTION="wifi profile"
    # Network Settings
    INTERFACE=eth1
    HOSTNAME=Attila
    # Interface Settings (use IFOPTS="dhcp" for DHCP)
    IFOPTS="dhcp"
    #GATEWAY=192.168.0.1
    # DNS Settings (optional)
    # Wireless Settings (optional)
    ESSID=essid
    KEY=network-key
    IWOPTS="mode managed essid $ESSID channel 6 key restricted $KEY"
    #WIFI_INTERFACE=wlan0   # use this if you have a special wireless interface
                            # that is linked to the real $INTERFACE
    #WIFI_WAIT=5            # seconds to wait for the wireless card to
                            # associate before bringing the interface up
    #USEWPA="yes"           # start wpa_supplicant with the profile
    #WPAOPTS=""             # use "" for normal operation or specify additional
                            # options (eg, "-D ipw")
                            # see /etc/wpa_supplicant.conf for configuration
    #AUTOWPA="yes"          # automatically configure WPA
    #PASSKEY=""             # wpa passkey/phrase. for use with AUTOWPA
    unfortunately, it doesn't work.
    here are the outputs to some commands:
    hwd -s
    Network    : Broadcom Corp.|BCM4301 802.11b module: bcm43xx
    so.. this tells me the module is the right one.
    lspci

    Has anybody used a card like this one?
    I am probably missing something, or then the problem is really with the module (which is loaded).
    Any idea?
    thanks!

    Hi...
    I have the same card and it took me a few days to set it working nicely... Here's my setup... Don't know about network profiles though.
    - driver: ndiswrapper (tried bcm43xx-fwcutter, didn't work)
    - networkmanager with knetworkmanager instead of usual network deamon (follow this link to install it http://wiki.archlinux.org/index.php/Networkmanager
    - don't forget to add your user to the network group, or else knetworkmanager won't work.
    Note about knetworkmanager... if you have a 64-bit architecture, you have to use the svn version from AUR. There's a bug in the current version.

    I think the big trick here is to use networkmanager. It is way better than usual network daemon.
    This is my result for iwconfig
    [root@note-leandro leandro]# iwconfig
    lo no wireless extensions.
    eth0 no wireless extensions.
    eth1 IEEE 802.11b/g ESSID:"AVEIRO-WLAN" Nickname:"Broadcom 4318"

    Rx invalid nwid:0 Rx invalid crypt:11 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0
    eth2 no wireless extensions.
    After getting a valid iwconfig output, just use knetworkmanager to choose which network you want to use.
    Hope this helps.

  • AEBS/Wireless Client Setup Help

    My computer seems to be set up and working properly for the internet - DSL modem > AEBS > G4. I'm having trouble getting my roommate's computer (also a G4) to connect to the internet wirelessly.
    I downloaded and printed out the manual for setting up Airport Extreme Networks but the toolbar and options are different from our computers network and AE utilities. I have the old white dome AEBS and I think the instructions I downloaded are for the new one.
    I'm also using WPA Personal security. Can anyone give me some tips on how my roommate's computer should be set up to connect wirelessly via my AEBS? Currently, if I try to select the base station on her computer, it's asking for a "WEP" password, I type in my password but it says there is an error joining the airport network "network name".

    I'm using the password (double checked it) I set up when using WEP on my AEBS setup and it's still giving me a password error when I enter the password when I select the network on her computer. I made sure I'm using enough characters for the password too.
    Could my problem be with the WDS mode? Does that need to be set up for the two computers on my network? Honestly, I'm not sure if I'll be lacking internet speed once I get it to work wirelessly and have thoughts that it may be better to get an ethernet router, any thoughts/opinions?
    I'd welcome any more help but I don't have a lot of time today to make changes but I'll let you know if I get it working.

  • C4385 WPA Password change dumps wireless

    I made the mistake of changing the WPA passphrase on my wireless router. Is there no provision for this in the c4385 setup? The printer will not work as a wireless device anymore. I even tried changing the password back to the orginal password. No luck. Still broken. I've uninstalled all HP software and have done a clean install. Setup doesn't offer the option of setting up the printer as a wireless printer anymore. It's going from bad to worse. DO NOT EVER CHANGE YOUR WEP OR WPA PASSWORD is the only lesson I've learned from this little experience. Anyone have any advice or similar experiences?
    ~m

    After two attempts at clean/rebooted reinstalling (with USB cable) on my last attempt worked inexplicably WITHOUT using the USB cable! Printer is working again. I had to change the password back to the old password. Now a new problem is happening the HP Digital Imaging Monitor continually pops up but I'm starting a new thread on that one.

  • New Airport Extreme N wireless network setup questions (WDS, D-Link)

    I have finally been able to set up my Airport Extreme N network after numerous attempts over the last few weeks. I was getting a very weak signal in front of the house where my wife's G4 is connected wireless to an old Airport card and where all the systems (XBOX 360; Wii and PS3) are also wirelessly hitting the network.
    The current configuration is as follows: In the office in the back of the house I have an Airport Extreme N basestation connected to the cable modem and have three workstations (One Mac and two PCs) wired to it. I set up a WDS network, so I set up the Airport Expresses as remotes. In the living room I have another Airport Extreme N basestation (as a remote as well) that is hooking up to the XBOX 360, Wii and PS3. I have enabled WEP security (not effecting the XBOX 360 since it is now "wired"). Here is the weird thing - I have a PC laptop with a D-Link Xtreme N card ( DWA-652) that cannot connect to the network. I enter the WEP password but it does not connect. Am I missing something on the basestation setup? Do I need to add the MAC address of the card anywhere. When I use the laptop's built in wireless it connects with no problem. By creating a WDS network did I disable the n functionality of the base station(s)? I am a lttle condused.
    Also, prior to going to an all Apple wireless network setup, I bought the D-Link Xtreme N Gigabit Router (DIR-655). I was regretfully about to return it to Best Buy but I had an idea which may or may not work. I know that the D-Link does not support WDS but if I was to set it up as the main router and added the "main" Airport basestation as a wired bridge could I maintain the WDS network? The reason I ask this is because I would love to keep the gigabit for the wired machines in the office. Also, I am wondering if the D-Link notebook card is incompatible with the Airport network.
    All I know is that I have spent alot of money and sleepless nights just trying to set this network up but thankfully Best Buy has a thirty day return policy so I will return what I can't use.
    I appreciate any help and advice anyone can give me.
    Thanks.

    Hello!
    I have noticed that some manufacturers (Linksys and possibly D-LINK) only accept upper-case WEP keys only.
    This drove me nuts when trying to integrate a Linksys PC PCMCIA card into my old "g" network.
    As far as using WEP, it's bad and broken; but I understand that your choice of security is limited to the devices that you are trying to network.
    For what it's worth, I have my network set up with the AEBS 'n' connected to my Cable Modem, with one of the ports going to a gigabit switch for my wired network. I then have two AirTunes set up as WDS extensions for music & Internet delivery to two separate areas. The AEBS 'n" serves up DHCP and routing for the entire network.
    It works quite well; I get 54 mbits/sec for the two WDS AirTunes, and 145 mbits/sec to one of my ATV's. My gigabit wired machines see data rates of 15-27 MBytes/sec (depending on the type of transfer).
    Good luck!
