Question about IBM ThinkPad T42 Notebook

Unable to connect to ad-hoc network

I´ve got a T42 with an Intel PRO/wireless 2200BG network adapter. I´ve set up an ad-hoc network. When I switch on the laptop it says "wireless networks found" Using Intel to manage the wifi. Screen shows the available networks. I choose the ad-hoc one and click connect but it just says Unable to connect to XXXXX.
I know the wifi works because I was using it in the UK and connected easily to a wifi router at a friends house but since I came to Spain and started the ad-hoc system - nothing! I also know the ad-hoc system works because I had it going between the main computer and an old desktop just to prove it worked.

Why does connecting to an ad-hoc network disconnect the shared mobile broadband connection?


You can be connected to two signals at one time, if I understand your statement. My question is, why is your laptop automatically connecting to a Ad-Hoc network? Your wireless adapter Intel Wireless 3945A/B/G,settings should be scrutinized. Perhaps this will help:http://www.intel.com/p/en_US/support/highlights/wireless/pro3945abg

I have an HP/Compaq 8230 that is 3 1/2 years old. Recently, my wireless has stopped working. "No networks found in range". It is an Intel PRO/Wireless 2200BG.


Do a wireless scan and see how many wireless connections are avaiable in your neighbor. If I was a beating men, that your wireless router is sharing a neighbor's wireless channel number.

Wireless network found


If it cannot find any networks, check to see if there is a wireless on/off switch on the computer - look carefully some are well hidden. The switch turns the antenna on and off but windows still detects the network adapter and thinks everything is ok.

System Crash


Hi

Intel 2200BG is known to cause this and similar errors when Wireless Application Protocol (WAP) encryption is used. The problem has been around since 2004 and new OS Drivers should fix this.

I recommend you download and install latest Windows Drivers (appropriate for your Windows Version) for Intel 2200BG Adaptor.

If this cannot be done, then setting your wireless to Wired Equivalent Privacy (WEP) encription (though less secure) will minimise these error conditions

NB: Google "w22n51.sys" for more info.

Mike

Wireless network connection, Intel (r) pro/wireless 2200bg says not connected. How do I get it to say connected? I have disabled it and then enabled it and to my surprise it still says not connected- How...


Try these first:

Make sure that the wep password is correct.

change channels to 1-6-or 11.

check is to make sure you are NOT using "IEEE 802.1x authentication for this network."

You can find at setting under "Wireless Network Connection Properties" and then under "Authentication" tab of your network properties.

This particular authentication method is periodically logging you off the network and re-authenticating.

Check the adapter in device manager to make sure that windows is not shutting the adapter down to save power.

Cordless phones1.gif and wireless ethernet cards use overlapping frequencies.As a test, you can unplug the AC cords from all the cordless phones in the area and see if it helps.

Intel Pro Wireless 2200BG problem or Linksys BEFW11S4 problem?


I had the same problem. If you are using the latest driver for your intel 2200BG (9.0.4.7). Try to roll back to a previous version. It solved my problems with being unable to connect to a Linksys BEFW11 router running WEP64.

I am now running driver version 9.0.1.9

Intel PRO 2200BG will not detect any network


This IS the solution: Set it to use 802.11b _ONLY_ Do this in Windows: Start->Settings->Control Panel->System->Hardware->Device Manager->Network adapters->Intel(R) PRO/Wireless 2200BG Network Connection->Advanced->Wireless Mode = 802.11b only Driver version: 9.04.36 (04.04.2007) PROset/Wireless Software: not installed OS: Windows XP

Wireless network unavailable no matter what


Tried these fixes with no luck, then realized the tiny "antenna on" switch on the front of my HP Mini 1000 (parallel to the on switch, just in front/under the keyboard) was glowing red instead of its usual blue. My antenna was off! Flicked the switch to turn on, and voila, wifi.
