Intel PRO 2200BG will not detect any network

I have a WInbook with an Intel PRO/Wireless 2200BG modem. It used to detect networks fine, but recently stopped detecting them. When I go into Device Manager, it is enabled, there is no yellow exlamation point next to it and properties tell me it is working correctly. I have tried to uninstall it and reboot. It then reinstalls it, but it still doesn't detect any network. I have a USB and also a PCI wireless modem which will detect and connect to networks with no problem. Any ideas on how to fix my internal one? I hate having to plug in these everytime I travel. Thanks.

    Hi - cannot detect my network with my IntelPRO/Wireless 2200 BG card. It will detect the network next door, but not mine, even though the network is up and I have other computers on it, one with an identical card, have tried swapping the cards over, and the problem moved with the card. So the problem is definitely with the card. have tried new drivers.

    my wireless used to to work great, but as of late it wont detect any networks. to be more specific. it will not show any networks when i click "view wireless networks" i will see it trying to connect to other networks, but never quite make a connection. when i boot up, it says wireless networks are within range but will not display them. when i try to manually add the network, it will show up only that once, and wont be there when i close that window. i have had this for nearly four years, and this just recently started

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

Is there a physical switch or a software switch (fn+F2) or anything on that laptop that you may have inadvertently switched or bumped??

Check your wireless channel. My router config was on 13 and the network adapter on 10. After I changed the router's to 10 it started working.

Revisa tu canal wifi. En mi router estaba en 13 y en el pc estaba en 10 (con un maximo de 11). Tras cambiar la configuracion del router a 10 empezo a funcionar.

Hope it helps.

I'm having the same problem with the same wireless modem. I have a physical switch and have tried it repeatedly - but it does not seem to work. There is an indicator light that should light up when I press the 'wireless connect' button - but it doesn't. My device manager also says the modem is working properly, but it clearly isn't. My neighbour can see my wireless network but my laptop doesn't see it.

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


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.
