WLAN disconnets frequentlly.

Hi,
I have 7 AP"s with same ssid, broadcast. When the users move from one place to another, they lose the WLAN connetions, some time the users disconnect and reconnect or some time the users need to reboot the pc itself to get the WLAN connection.
I am using ACS 3.3 for authentication.
cisco AIR-AP1231G-J-K9 (C1200-K9W7-M)
System Software Filename: c1200-k9w7-tar.123-2.JA
System Software Version: 12.3(2)JA
Bootloader Version: 12.2(8)JA
What can be the problem?

No specific patches that I'm aware of for your specific config choices.
If you have the option, I recommend moving from C-KIP to T-KIP ... CKIP is Cisco proprietary and "may not" be supported by the Intel drivers ... at least as well as TKIP which would be more standards-ish.
If your clients and AP radios support it as an option, AES would be better security than WEP, though in this case you could have TKIP run a key rotation and make it a bit more secure.
I also suggest you check the Intel Proset features / options and make sure the "Cisco Extensions" (CCX) are enabled ... I think they would be in order to support LEAP, but verify it .... I'm getting old & feeble-brained and I don't have my laptop available to check it myself.
Let us know ...
Good Luck
Scott

    Apple, as I said, does not repair your iPhone. All hardware service issues are handled by replacing the unit. So they can't handle the home-button issue without also addressing the issue of the cracked screen, for which they'll almost certainly charge you. But you can make an appointment at an Apple Store or call Apple tech support and plead your case.

  • Satellite A505-S69803 - How to replace the Wlan card?

    Before I go into the details of my problem.
    I have rolled out a DSL product, set up hundreds of wireless routers. I was a notebook service tech for 3 years for laptops as well.
    I picked up a toshiba cause the price is right, and so far I am learning you get what you pay for.
    This machine has a realtek wireless card.
    As everyone knows.. Realtek == cheaply made bad hardware.
    Toshiba refuses to replace this card.
    I need to buy a new card for this laptop.
    I need to know if this is a mini-pci, half height mini-pci, a pci-e, or mini-pci-e card.
    I plan on getting an intel for it.
    I also need the whitepapers so I can remove the wrist pad / bezel on this unit. They have users guides, but unlike other notebook manufacturers, do not have their service manuals available.
    Any assistance to get this laptop fixed would be appreciated. It is leaving town with my parents soon.

    hi vlad2,
    realtek is also known to run perfekt under linux - this indicates that the hardware isnt so bad as you think...
    toshiba sells the unit as specified - if you wanna have some other hardware choose another notebook modell or replace the wlan by yourself...
    if unsure what card is in it , open the door under which the card is located - for an notebook tech pro like you no big thing - and check it.
    replacing this piece should be easy...
    to answer your complaint: +"Toshiba refuses to replace this card."+
    sure this! if it works there is no need to replace and you will get allways the same as spare because this modell comes with it...
    i dont like it to repeat me but a notebook technician should be able to disassemble this machine (you will ruin your warranty with this action)
    disassembling the covers is a service partner thing - not for customers...
    by the way: +"I am learning you get what you pay for"+ means what you see is what you get, spending some extra money is not bad at all...
    you cant get a mercedes for the price of a little car...
    and whats your technical problem with the wlan?

  • Tecra M9 PTM91E : WLan Intel 4965AGN disconnect every few minutes

    I have a M9 laptop, model PTM91E. The wireless connection keeps disconnecting (then reconnecting again) every few minutes. This happens on every wireless network I try connecting to. Here what I have on my laptop: -
    Intel Wireless WiFi Link 4965AGN
    Driver version 11.5.0.32
    Driver date 9/26/2007
    XP Pro
    Toshiba suggest I upgrade to Windows Vista, something I have nigtmares about.
    Does anyone else have the same problem? Any solutions?
    Thanks

    I have read about the similar issue on a Sat A210 and with Atheros WLan card.
    The solution was a BIOS and WLan driver update
    So check it out.
    Good luck

  • WLAN Sync does not work after Update to version 10.5.1

    Today I have updated my iTunes to version 10.5.1.
    Before the update my iPhone was showed under Devices in iTunes and I could start the WLAN Sync directly from iTunes.
    After the update my iPhone is only showed when I connect it via the USB-Cable. I can't sync via WLAN.
    I've got an iPhone 4 with iOS 5.0.1 and a MacBook Pro with Mac OS X 10.7.2.
    Can someone help me?

    I am having similar trouble. My Apple TV (first generation), and both my iPhone 4 and my wife's 3GS are missing from the device menu. The "Sync via Wi-Fi" boxes are checked and all devices can see the network. I looked at my router's (using the cheap actiontec supplied by Verizon FIOS for the past year) settings and they seem to be OK.
    Any help would be great.

  • Satellite M70-394: WLan does not work after wake up from standby

    Hi all....
    I have a problem with my WLan connection and hope one of you may be able to help. Starting my computer from off there isn't a problem with the WIFI connection but if I put the computer into standby by closing the lid and then restarting it from there the light comes on briefly for wi fi but then goes off and the only way I can connect is through a cable.
    Any suggestions would be gratefully appreciated.

    Hi
    I have read in the forum that some similar "Wlan standby" issues were fixed by BIOS update.
    I think you should compare the BIOS version on the notebook with the BIOS which is available on the website. If there is a new update try to upgrade it
    Be sure that you have chosen the right BIOS.

  • Tecra S3 - Wlan does not work after Win XP installation

    Hello everyone,
    I have recently purchased a Tecra S3 PTS30E-0TL059GH without operating system.
    I've installed WIndows XP professional.
    Everything works, except for the wireless lan. I can switch it on, but it doesn't seem to find the right drivers.
    The device manager states problems with the networkcontroller and two other unknown devices.
    I've installed all drivers from the toshiba website, but it still won't work.
    Any help is appreciated!
    Thanks!

    Hi
    I think the notebook supports INTEL 802.11 B/G WLan card but I'm not 100% sure about that...
    In my opinion you should try to identify the WLan module.
    How to do that?
    In such case the usage of the PCI database should be very helpful.
    More details here:
    [How to identify an unknown device (e.g. Wireless LAN module)?|http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=78]
    Knowing the exact WLan specs, it should not be a big deal to get the right driver.

  • Easy Keys and Fn+F8 (WLAN on/off) don't work

    Hello guys,
    I have bought a new Toshiba Satellite A100-490 last week. I have tested all hot keys and function keys with the pre-installed Windows XP MCE. Everything worked.
    But I needed a new customized installation of Windows XP Professional and Windows Server 2003 on the notebook. So I installed the XP Pro from a original CD-ROM and all Toshiba drivers, except of some special Managers (Assist, Config Free, SD Memory Format, Wireless LAN Client Manager, ...).
    From the Easy Keys (Browser, Media Player, Play/Pause, Stop, Backward, Forward) only the Browser and Media Player Easy Key work. Which driver is responsible for the other Easy Keys (Play/Pause, Stop, Backward, Forward)?
    The next problem is, that the Fn+F8 (WLAN switch) hot key doesn't work. But when I disable the WLAN over the hardware switch, there comes a MessageBox that I have to enable the WLAN over the hardware switch first. Normally there has to come a On-Screen-Display. What is wrong?
    Please help me. Thanks!

    Hello Silas,
    I have all the drivers you mentioned already installed, but nothing changed.
    So I am going to install all the software and drivers again.

  • When trying to update the i phone " fault 1630" occurs - both when connected to WLAN or USB. What can I do?

    When trying to update my i phone IOS 5.0 (connected by WLAN and USB to my computer) there is always "fault 1630" saying I`ve got no connection to the internet / network, which seems to be wrong to me (phone is online). What can I do?

    Thanks.  I have followed all the instructions as recommended and nothing has worked so it looks like the restore/update may have been interrupted - would loss of internet connection do this?
    Yes it would, possibly even brick it.
    Have successfully connected my ipod nano with iTunes so looks like the device driver is working.
    Can I use my ipod nano USB connector to check?
    It is not much help to you, since the device that you need still not recognized.
    Anyway looks like I may have to swallow the loss of data.  Have set-up a call for tomorrow with Apple support so will wait until after this before doing the factory restore!
    Good luck, but if you expect miracle from that call good luck again.

  • E72: Unable to connect to WLAN

    Something weird is with my E72. I had been happily using the WLAN in my house for a few months now. Then yesterday it suddenly failed.
    Unable to connect to the wlan. The default browser showed me "Unable to connect. WLAN not found"  and "Unable to perform operation"
    But during a WLAN scanning, I can clearly search my house WLAN showing me "2WIRE*** found".
    E72 had really give me lots of problem. Hope this will be my last problem I encountered with my phone. Thank is advance for any suggestion for this problem.

    Try with Hard Reset (shift+space+backspace+on/off). Make a full backup before!

  • How to enable WLAN on Satellite 2410-504?

    Hello,
    please could you help me I am a little bewildered. I would like to wifi enable my laptop. It is a Toshiba Satellite s2410-504. If you know what this laptops short name is that would really help me. I don think it has a centrino chip so I think I will need to wi-fi enable it. I have researched it on the web but I am confused by terms like cardbus. Does my laptop have a cardbus? If not, how will I wi-fi enable my laptop?
    Any suggestions for a competitively priced product (is it a chip or what?)
    Thanks.

    If the unit can be upgraded with the minPCI WLan card so mostly the slot for a WLan card is placed at the bottom of the unit.
    Im not 100% sure if its WLan ready or not.
    However, if its possible to upgrade the notebook with the minPCI WLan card so you can order this form the Toshiba authorized service partner in your country.
    If its not possible to upgrade it so I would recommend switching to the external solution like a USB WLan stick
    Such sticks are not very expensive and very easy to use

  • Internet access problem via wlan on Orange Nokia N...

    I have had a nokia N80 for a few days, and can I get the wireless access working to access the internet, can I hell!
    I can get the phone to connect to my router via dhcp or static ip address. I can enable security, have an open network and can even ping my phones ip address so I know the link is working via wireless.
    It's just when I attempt to connect to wlan on the internet is says the usual 'web no gateway reply'. Has anyone got this working with a linksys wag54gx2 wireless router?
    Stan..

    Hi,
    Don't know if this might help?
    Menu > Tools > Settings > Connection > Access Points. Open the connection in question and press Options > Advanced Settings > IPV4 Settings > DNS Address. Enter the IP address of your router here, then reboot the phone and try to connect again.

  • Cant ping windows computers with new E4200 LAN/wLAN

    just replaced a WRT54G with E4200. Most functions work well. 4 wireless computers (1 Macbook, 3 Win 7), 1 wireless android, 1 wired Win7 computer, 1 ethernet connected hard drive, 1 ethernet connected printer. All computers can ping router, access hard drive, access internet, ping android and ping Macbook.
    However, router, nor any computer, can't ping Win7 computers. Apparently IP based connections between WinX computers is blocked. My real applications are to Remote Desktop Connect from 1 Win7 computer to another, or to run a DLNA music server on 1 Win7 computer, accessed by another. (the LAN connected computer is the server, accessed by a wLAN client. All worked fine on WRT54G router, but can't connect thru E4200.  When these apps failed, I tried PING, and that failed as well.
    All computer's IP addresses are properly served from E4200 via DHCP, and are visible thru the router's DHCP Reservation panel.
    Cisco Tech support suggested turning off the router firewall, and then turning off all of the internet filters, but neither of these ideas helped.
    Any thoughts

    Did you reconfigure the firewall on the Windows computer? You have connected the computers to a new router, i.e. a new network and it should be by default untrusted.

  • Problem when try to use ACSE+ Windows AD to authenticate two kind of WLAN c

    I met a problem when try to use ACSE+ Windows AD to authenticate two kind of WLAN clients:
    1. Background:
    We have two WLAN: staff and student, both of them will use PEAP-MSCHAPv2, ACSE will be the Radius server, it will use Windows AD's user database. In AD, they create two groups: staff and student. The testing account for staff is staff1, the testing account for student is student1.
    2. Problem:
    If student1 try to associate to staff WLAN, since both staff and student WLAN using the same authentication method, the auth request will be send to AD user database, since student1 is a valid user account in AD, then it will pass the authentication, then it will join the staff WLAN. How to prevent this happen?
    3. Potential solution and its limitation:
    1) Use group mapping in ACSE(Dynamic VLAN Assignment with WLCs based on ACS to Active Directory Group Mapping), but ACS can only support group mapping for those groups that have no more than 500 users. But the student group will definitely exceed 500 users, how to solve it?
    2) Use methods like “Restrict WLAN Access based on SSID with WLC and Cisco Secure ACS”: Configure DNIS with ssid name in NAR of ACSE, but since DNIS/NAR is only configurable in ACSE, don't know if AD support it or not, is there any options in AD like DNIS/NAR in ACSE?
    Thanks for any suggestions!

    I think the documentation for ACS states:
    ACS can only support group mapping for users who belong to 500 or fewer Windows groups
    I read that as, If a user belongs to >500 Windows Group, ACS can't map it. The group can have over 500 users, its just those users can't belong to more than 500 groups.
