My phone is on Windows 10 Mobile, build 10586.242. I can't connect to my home wifi network whereas other devices can. I've tried forgetting the network and reconnecting, but my phone says "unable to connect". How can I fix this?

This has been a frequent problem with Windows 10 Mobile! There are previous questions asked here based on this but all were WP 8.1 related.

  • Do you know what type of WiFi network it is and what authentication is being used? – Rowland Shaw May 5 '16 at 8:10
  • What phone do you have and are you on any of the Insider Preview rings? – Neil Turner May 5 '16 at 14:05

What is your home WiFi set to use as authentication? If it is using one of the older formats, you won't be able to connect. MSFT could really improve the error messages but Windows 10 Mobile has issues with the old TKIP standard.

So: set your router to use WPA2 AES and on the device:

Wireless Setting > Manually > WPA > Cipher Type > AES

One other thing that also helped in some cases was to switch from 5GHz to 2.4

  • its already on wpa2 aes setting. my phone didnt connect with network yesterday, when i tried just now, its getting connected. dunno if it connects after sometime. this problem has been troubling me since i reset my phone 2 weeks back. – Ram Raj May 4 '16 at 5:19
