Not working wlan - HTC Touch P3450 Smartphone

Hello

Disable firewall settings to check if it doesn't block connection.

1) Update the WLan driver. In most cases this solves connections issues.

2) Go to device manger -> WLan card -> Properties -> Advanced tab and check if the WLan modus 802.11 B/G or N has been set to the same Wlan modules supported by router!

3) Disable the WLan encryption and password on the router and check if you could connect to the router without any security settings. Do this only for testing purposes. If it connects properly, enable the encryption password and try again.

4) Disable WLan power saving! This can be done in Win Power Management. If that doesn't work, perform a system restore, set your computer to how it was the last time you were on the internet.

Not sure if this will work for your model but its worth a try. Copied from MSI support faq website
You have to press the WLAN button located right next to the power button in order to enable/disable the Bluetooth function. Press WLAN button once, Enable WLAN. Press WLAN button twice, Enable Bluetooth. Press WLAN button thrice, Enable both WLAN and Bluetooth. Press WLAN button four times, Disable both WLAN and Bluetooth.

Try uninstalling the WLAN from the device manager and then reinstall from the Vaio Recovery Center which can be accessed from Windows Help And Support

To enable/disable WLAN, please press "Fn+F11" to execute the device: (then follow below steps accordingly)
Note: there are four stages in all, assumingly both bluetooth and wifi are installed.

First stage : press Fn+F11 = Enable WLAN only
Second stage : press Fn+F11 = Bluetooth On + WLAN Off
Third stage press : Fn+F11 = Bluetooth On + WLAN On
Fourth stage press : Fn+F11 = Bluetooth Off + WLAN Off

After enabling the WLAN, search the Access Point and connect with it. Now, you may use the WLAN.

If this does not work, check if the driver is installed in your computer by going to the device manager. check under network adapters. If the driver is installed, uninstall the current driver and restart the computer.

If the issue still persists, you may download the driver update at the msi website: http://www.msi.com/index.php?func=nbdriver&maincat_no=135&prod_no=1474. Just make sure the driver you're downloading is compatible with yoru operating system

I am not sure of the chipset of your wireless card as it differ from country to country. So I am giving you the link for all the three chipsets according to Operating system for your Notebook.

Check out which chipset works out for you.

TRY REINSTALLING THE WLAN DRIVER. OR CHECK THE INTERNAL ANTENA CABLES OF WLAN. IF IT NOT WORKS. THEN THE ONLY SOLUTION IS TO REPLACE IT WITH THE WLAN CARD.
DONT FORGET TO VOTE.

The WLAN may be faulty or the driver got corrupted.
Reinstall the WLAN driver and check the Device Manager to see it the WLAN is working and enabled, if it is then configure it to match your wireless router settings.
If this doesn't work the most likely the WLAN card is faulty.
To get a wireless connection again, purchase a PCMCIA wireless card and insert it into the PCMCAI slot, install the driver for this wireless card and configure it to match your wireless router settings.

I am now on the same kind of computer and I used to have this problem- dell said it's a motherboard problem and they replaced it for free. Now it works just fine!

I'll need more information to give you an effective answer. If your wlan was connecting just fine, and now you don't have a stable connection, it could be a range issue and you'll have to get closer to the access point.
If your wlan doesn't work at all, and won't get recognized by your computer you may need the latest drivers, in which case I'll need the model number of your wlan device.
If it works, finds your wireless connection but can't connect, try resetting your wireless router.

Your WiFi works only if your phone is in a WLAN network.Select Menu>Tools>WLAN Wizard.The phone will automatically search for availiable WLAN networks.Select the desired network.Click Options>Start Web browsing.The phone will automatically create an acces point and you can browse the internet.
