Dell Inspiron 14z Ultrabook wifi connectivity problem

To be more precise, in the beginning it only sometimes goes into limited or no internet access mode. Sometimes rebooting or just waiting for a bit and the exclamation mark would disappear. And then it became more frequent and finally it just stopped working completely, ie, always an exclamation mark at the wifi icon. Using a cable works fine.

Hi imseen,

I would suggest you to run the Windows Troubleshooter. Right click on the network icon in the taskbar and click ‘Troubleshoot Problems’. Please remove all the wireless profiles and create a new profile. You may refer to the link: http://bit.ly/10dZEFI.

 You may completely uninstall the wireless drivers from the device manager and then reinstall the latest drivers from Dell support website. Please paste screenshot of device manager with ‘Network Adapters’ expended.

Keep me posted with the information. I will be glad to assist further.

Hi I have the same issue as above - the connection regularly drops out and reconnects. Sometimes it can be for a minute, other times it could be for an hour requiring me to connect to ethernet.

It is a Dell 14z ultrabook running windows 8.1 (problem existed on 8.0 and the update has had no effect).

The video card is as follows:

Intel (R) Centrino (R) Wireless-N 2230

Driver Version 15.10.0.12

Please advise how to resolve the issue?

Regards,

JJ.
