Hello all,

 

I have a fairly new Toshiba S855-S5378, seems to be a great laptop. Recently the wifi completely stopped working. It will pull up all of the surrounding WiFi connections but will not let me connect to any of them. It also seems to pull them up with weaker signals then it used to as well. I have tried the Windows troubleshooter etc. It is my work computer, many other computers are connected to the same connection so I know the problem is with the computer.

 

The computer works flawless hardwired, can access the internet etc but I really need the wireless and am not really sure how to troubleshoot this. Thank you for the help.

What is the OS? 32bit or 64bit?

 

In Device Manager, does it list the make and model of the wireless adapter? If not right click the device, select properties, and in the details tab select Hardware ID's in the dropdown box. Copy and Paste the first line in your next post?

Thanks for the response. It is windows 8 64 bit.

 

The wireless adapter reads: Realtek RTL8723AE Wireless LAN 802.11n PCI-E NIC

 

There is also something else that says: Qualcomm Atheros AR8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30)

Just to verify, this is Windows 8 and not 8.1, correct. The wireless driver is not a easy one to find. I thought there may have been an update but even Toshiba says the Realtek driver has to be uninstalled before upgrading to 8.1. One other thing you could try is to do a Windows update, look under optional updates and see if Windows shows an updated driver for your wireless adapter.

 

Edit: The Atheros is you hard wired Ethernet Controller.

For Windows 8 64bit, Toshiba shows this as the latest driver.

Sorry for the super old bump, but I never did get the internal card working, pluging in a wireless usb stick everyday gets quite annoying. Does anyone have any idea on how to fix this?

Did you try installing the driver. This is the one for Windows 8.1 64bit

I would have to say that if your USB adapter works then you are having a hardware problem. If the above driver does not solve the problem then I would recommend you get one of these so you can leave it in all the time.
