2 days ago my wireless card stopped working. I decided to try with a wireless PCI and that works.

I have a Toshiba Satellite A55-s326 and 2 days ago my wireless card stopped working or something like that, this is what it does.
The computer with the wireless indication on the bar is with an “x” and always appears that the computer can’t connect with the wireless net, I open it and click on connect and seems that is working but after a while doesn’t do anything.
After many tries I decided to try with a wireless PCI and that work.
Can I test my internal wireless card in any form or what can I do to know if I have to replace my internal wireless card?
I don’t know any test utility for testing a wireless card. The only way to test it is trying to connect to a good working wireless access point.

First of all, check if wireless antenna switch on the side of your laptop is turned on and the Wi-Fi LED lights up. I know that this advice sounds funny, but I’ve seen some people who didn’t know about this little Wi-Fi switch on the side even though they owned the laptop for months.
You should check if the wireless card is seated properly. If you carry the laptop a lot, it’s possible that the wireless card popped out from the connector. You can easily access the wireless card from the bottom and check if it seated properly. Reseat it just in case. When you remove the card, check if the connectors are oxidized or dirty, clean them if needed. If you turn over the laptop, you’ll find the wireless card under the hatch in the lower right corner.
I would also try to reinstall the wireless card driver. You can download it from Toshiba website or reload it from the restore CD.
