Problem in Wireless LAN

Hi, I have T61 Dual 2 Core laptop 2.1 GHz and 3 GB RAM. Since one year I am using builtin wireless LAN but now problem started, when I switch ON of wireless LAN button, it automatically off after 2 to 3 minutes and also light of wireless LAN is off. I need to OFF and ON the wireless LAN button to start working again Internet but after 2 minute it again OFF?
What is the problem? either wireless LAN is failed or some virus or software problem?

go into your control panel -> system -> hardware device -> wireless card property, switch off power save mode, switch roaming aggressiveness to low and switch power output to maximum.

Jin Li

Go to Configure> Controllers
and then which controller have config mismatch...on right side click on mismatch in Audit status tab.
After that it will ask for audit now, click on that. After auditing it will show you the two option:
1. Restore PI values to Controller
2. Refresh config from controler

PCI Card Slot - Wireless LAN Card Problems - Help!

Help.
I'm having problems getting my board to recognize both:
Linksys WMP11 Wireless LAN card; and
Netgear WG311T Wireless LAN card
(returned the Linksys card, but the Netgear card had the same problem).
Neither card is being picked up by Windows (XP Home), although both the "power" and "link" LED lights up when inserted. I've tried every PCI slot, same issue. Nothing shows up in the device manager, and no new hardware is detected. The Netgear software tells me that the card has not been installed.
Am left thinking I need to RMA the board. Any suggestions woudl be much appreciated.

My roommate has a similar setup as you and I am having the same problem getting a pci wifi card to work in the machine. I have tried both a Linksys WMP54G and a Netgear WG311. Both cards will scan for networks bit will never connect my router (Linksys WRT54G). Just to get them to recognise the network, I have to turn off WEP, and turn on ESSID broadcast. Both of these cards work prefect in other computers. I know it not a signal problem because I can take my laptop and set it in the same location and it gets excellent signal.
I have tried changing slots in the machine, the wifi cards were the only PCI cards in the machine and an GeForce 6800 GT in the AGP slot. I have no idea what the problem could be. But I'm leaning towards the mobo at this point.

Voice over IP Roaming problems between 2 Wireless Lan Controllers.

Hello,
we have problems with Voice over IP roaming between 2 Wireless Lan Controllers, this problem is not always happening. I have attached the detailed configuration. We are using LWAPP 1242 & WLC 2106 Controllers.
The phones they are using are Siemens Enterprise optiPoint WL2.
Is there maybe something wrong with the configuration our can I try some different settings?

When a wireless client associates and authenticates to a WLC, it places an entry for that client in its client database. This entry includes the MAC and IP addresses of the client, security context and associations, quality of service (QoS) contexts, the WLAN, and the associated LAP. When a client roams to another LAP associated to the same WLC, it just updates the client database with the new LAP information so that the data can be forwarded appropriately to the client. When a client roams to a LAP associated with a different WLC, either in same or different subnets, it sends the information in the client database to the new WLC. This helps client to retain its IP address across roams and maintain uninterrupted TCP sessions. For more information on roaming in the WLC environment.

Problem arised after updated the intel wireless lan

Hello, everyong
My laptop is T510. I just updated the intel wireless lan to the version of 15.02.0000.1258. After the updates, my wireless router was down when the laptop started. Initially it can connect to the router for a few seconds, then the router was down with all the lights going off except the power light. Once I restart the router, everything goes fine, my laptop is able to connect to the router without any problems. So I have to restart the router everytime when I start my laptop. Please help me. How to fix this problem?

Why do you have to restart the router.
Have you checked the computer WiFi profile? Why or what is not allowing the connection.
You could delete the computer profile in Access or whatever you're using and discover, reconnect to it again as if its the first time. It may resolve the issue which is unknown.

P43 Neo - PCI wireless LAN performance problems

Hi,
i recently installed the Neo P43 Board. Everything runs fine so far, except PCI wireless LAN (maybe more, it's the only PCI card I use). I already updated the BIOS to 1.6 but it doesnt fix it.
I tried 2 different WLAN cards (1 Realtek and 1 Ralink). Both of them basicly work, but the transfer rates are painfully slow although the connection quality is reported as good enough.
Anyone else having issues?

How low are the transfer rates?
It varies a bit but most of the time very low (as low as 1kbps or sometimes not working at all)
What are you connected to (Router?, What kind of Router)?
Connected to a router. It's a "Speedport" router, I think they are manufactured by Siemens.
When you talk about the transfer rate, do you mean the transfer rate that you get when you try to copy files to another system in a Wireless network?
I mean downloading files from the Internet over the router, or generally the connection to the router (like status page).
The Ralink card used to work just fine in my older PC with an Athlon XP / Nforce Chipset (and several other PCs), but on the Neo P43 makes problems with both, the Ralink and the Realtek card.
I'm not absolutely sure it is the board that makes these problems, but I can't think of any other source for this problem anymore.

N82 V30.0.013 Bluetooth and Wireless LAN problems

I am using an N82, but it looks like there are similar problems with everything using similar firmware. I didn't have any of these problems with the V20 firmware that came with the phone or after the first V20 upgrade I used.
I find that my wireless LAN connections sometimes only let me browse a few pages before I get the "web connection timed out" message. If I change wireless LAN connection (I have two, mostly for testing purposes) I can continue browsing. Of course the same error may happen causing me to switch again. Sometimes it just works. Both have WPA set up and the passwords are clearly correct. If I use Real Player I can typically listen for as long as I like. Sometimes the connection to the server will drop for Real Player but reconnecting will work (don't have to change wireless LAN network). With the web browser it seems like the data connection is dead, not a server timing out - the message appears instantly. I think have seen the same problem once with my 3G connection, but I haven't recreated it. Could be my imagination!
I have never had any problems with IMAP email using either the Nokia client or Profimail on either the wireless LAN connection or 3G. It leads me to believe that there is nothing wrong with the wireless LAN side of things and it may be more to do with the web browser, or perhaps just that the email clients are only talking to one server helps (DNS problems?). Has anyone experienced similar problems with an alternative browser?
I have also found that when I get to work my bluetooth dongle doesn't connect to my phone. If I disable/enable bluetooth on my phone it will connect. I had this problem with my N80 with the first firmware I had on it and the problem went away after an upgrade.
So, it seems that both connections are fixed by turning them off and on again.

Having both routers the same IP address is a little bit confusing, but possible since each router creates it's own subnet and provides full PNAT support. Actiontec DSL modem has to have DHCP enabled since Linksys WAN (not LAN) port should be connected to one of 4 Actiontec LAN ports. Linksys should not have any configuration setup in regards of your WAN account. Just set it to dynamic address. In ohter words:
1. RJ-11 connect to Actiontec mode/router.
2. Actiontec modem should be configured to acquire an IP address from Verizon and to provide all authentication info to Verizon.
3. Actiontec modem should be configured to allow clients to acquire dynamic IP addresses -- DHCP enabled.
4. Linsys WAN (not LAN!) port should be connected to Actiontec LAN port.
5. Linksys should be configured to acquire dynamic IP address and no authentifacations.
6. Configure Linksys to be DHCP enabled or you can use static IP addresss if you want.
7. Wireless devices would be connected to Linksys and on the way to the Internet addresses would go through double NAT conversions. Any wired device connected to Linksys would have similar features. Any device connected to Linksys should be able to connect 192.168.1.1 assigned to Linksys, but not to Actiontec.
8. To be able to connect Linksys and Actiontec would no be able to communicate unless you split 192.168.1.0/24 into smaller subnets and set specific routes in the table. But even you do so you will not be able to access 192.168.1.1 accross subnets boundary.
Hope it helps.

HP Officejet 6500, Windows XP and 7, wireless LAN security code is not accepted

The security code of my wireless LAN is not accepted by the HP6500A. According to the diagnostic software of HP a code consisting of more than 50 characters is required (the total number of characters can not be identified because the code isgoing on out of the window). The security code of the route consists of 12 characters. Resetting the printer is not solving the problem.
This problem was identified after rinstalling the software after problems with printing: connection with the printer was identified; message: "busy with printing", but no printing result at all.

Security codes can be in ASCII or HEX. I'm guessing that the diagnostics is reporting HEX and the printer entry is in ASCII.
You can try running the diagnostics SW on the Windows 7 computer. It might return the key in ASCII.
A good option is to get the password from somewhere other than the diagnostics. Maybe you stored it somewhere or wrote it down? Once you get it try to enter from the front panel.
Can I get a little information from you?
What router brand model?
What security mode are you using (WEP, WPA, WPA2)?
Which model of the 6500 do you have (6500 or 6500a)?

Lenovo Yoga 13 Downgrade to Windows 7 Wireless Lan Driver & USB3.0 Driver

Hey guys,
I have purchased the Yoga 13 in U.A.E in last Feb. with AED4,999.00
But some programms does not work with Windows 8. So I am using Windows7 with multi-boot.
Guess you guys also have such problem.. eventually finding out the WIFI Driver & USB3.0 Driver.
Now, I have succeeded in installing both of them.
1. Wireless Lan Driver : Realtek RTL8723A Wireless LAN 802.11n USB 2.0 Network Adapter.
   The way I found this driver is... Download all the REALTEK driver in a designated folder.. of course uncompressed.
   And then using the contraol panel... updated the driver with the designated folder.
   Now it is working very well.
2. USB3.0 Driver
It was an easy game. I just have downloaded thee Intel USB3.0 Driver for Windows7... you could find it through google with easy.
And just installed it. It works very well.
=> You could download the file at http://me2.do/xKBVnWo3
      (just put password : 4321 )
If you guys have problem with above issues... or need the file let me know with my mail at xxxxxxxxxxx
Anyhow, there are still two drivers I couldn't find.

Windows 8 and Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC

Hi!
I hava a Toshiba L650 - 107 PSKI JE and I am having a problem with the my wireless network adapter on windows 8.
My network adapter is Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC and works fine on windows 7. Two days ago I formatted my hard drive and install windows 8. The problem is that for much drivers I keep installing, The wireless keep turned off. There's no way I can move the slide from off to on.
I already tried a lot of drivers from toshiba and from realtek but doesn't work.
I went to see the Network Connections (Control Panel > Network and Internet > Network Connections) and the Ethernet is fine, I connect a cable and it is fine, but wi-fi says "Not connected".
How do I solve this problem?

Satellite L650-107 (PSK1JE-00P003EP)
Downloads here.
A computer from Portugal? (Specifications attached.)
This driver should work on Windows 8.
Realtek Wireless LAN Driver
But your problems may be more fundamental. Prior to loading Toshiba-specific programs, you probably need to install something like this.
Toshiba System Driver - Windows 8 beta
And for the function keys to work, you'll need still another Toshiba utility.

Issues after changing the AP Name on Wireless LAN Controller

I recently changed the AP Name of all the Wireless Access Points in my branch office (which are all associated to the branch office Wireless LAN Controller(s)). After that I noticed that all branch office employees are unable to connect to the employee SSID. The employee SSID uses web authentication and employees are authenticated using Head Office AD via Cisco ACS, both located at the Head Office.
There are other SSID's on the WLC which all work fine, but only employee SSID which uses AD authentication does not work. AD authenticaion is working fine because employee's in HO are successfully able to connect to the employee SSID at HO.
The branch office is connected to the HO via a tunnel link. We noticed that if we restart both the ASA at either ends of the tunnel. The employee SSID starts working again but only temporarily for a day or so... what could be the issue? Can renaming the AP's cause issues? How can I fix this problem?
Thanks in advance

Thanks Elliott,
I did the debug like you said and I am getting the following debug messages:
*apfMsConnTask_0: Jun 20 08:18:14.580: Deleting the client immediatly since WLAN is changed

Why does my wireless LAN stop mid session

I start up in the morning and everything is fine, but at some point during the day, my wireless LAN quits. I've changed modems and routers but I still have the problem. My provider sees nothing on his end and other computers on my home network work fine. When I turn the wireless off and back on I get a new lease on wireless until it decides to do it again. I'm running the latest OS X 10.8.2 (3.1 GHz Intel Core i5) with 4GB 1333 Mhz DDR3. Has anyone had this problem and if so have you found the solution. Thanks!

Click the Assist me button and select Assistant. Follow the prompts. How far do you get?

Domain Logon fails using wireless LAN

Hi Sir,
I am setting up an ACS server to authenticate the wireless LAN users using PEAP MS-CHAPv2for one of my existing customer. They need to login to domain whenever they need to access to the network
On the wireless client's end, the OS is Xp and the client will use Windows XP wireless zero configuration. I have put in the necessary setting in order for it to support PEAP. I managed to get authenticated by checking against the passed authentications log found in the ACS.
However, the problem happens when I tried to reboot the desktop and Domain Logon appears, I was not able to logon to the Domain. I think I know the cause of the problem. It was because the wireless card is not authencated yet prior to the Domain logon screen.
How can I connect to the wireless network prior to the appearance of the Domain logon windows. There is no options for me to try in the XP wireless zero configuration to activate the wireless LAN before the Domain Logon windows comes out.
Thank you.
Delon

Even if still it does not work, ensure the following:
1) Change the logon credentials for the ACS services to use a domain administrator account. Often times the local member server administrator account does not have any rights on the AD.
a. Ensure the ACS services start with the Domain Administrator account.
b. Ensure you are able to log in to the server using this Domain Administrator account .
c. Ensure the Domain Administrator account (or the account with which the services start) have privileges to log on locally, Log on as a service and Act as part of the operating system.
2) Ensure the FQDN of all domain controllers is added to the DNS names.
