My Lumia 925 is able to recognize all Wi-Fi networks in the vicinity when I switch on the Wi-Fi. However, it is not able to connect to any network when I try. it says: "Can't connect to this Wi-Fi network now, try again later". It has been doing this for two weeks now. For a year my phone was able to connect to my home Wi-Fi and other Wi-Fi networks without any issues. How can I fix this?
I've had the same problem from time to time with my Lumia 920 and then later with my 930. Turning wifi off and on doesn't seem to fix it.
To solve this, usually I found that powering off and then starting again would allow connection.
Annoying, yes. I don't know why, but it may be something in one of the OS upgrades. Did you upgrade your Windows 8.1 OS soon before these issues started? Hopefully a future OS upgrade will eliminate this problem.
