Sometimes WiFi networks are not picked up on my Moto G. Switching WiFi or flight mode on and off does not solve the problem, however a phone reboot does.

Does anybody know of a way I can reset the WiFi completely without rebooting the phone?

For example, with 3G issues I would go to the testing menu (*#*#4636#*#*) and switch the radio on and off, or switch flight mode on and off, which would typically cure the problem. Anything similar for WiFi? Thank you.

Is it rooted? You could flash a newer / different radio. Have you tried any wifi fixer applications from the play store? Has this always happened or just started? Have you done anything with the device lately: updated firmware, rooted, flashed a rom or mod, dropped it? –  RossC Jun 5 at 14:20
    
This phone is not rooted and has the standard 4.4.2 software. This is an issue that has started with a particular network after working fine a few days. I have only updated things like Chrome, Chrome beta & the Google music player. I have not tried WiFi fixer apps, any recommendations? –  nsandersen Jun 6 at 1:29
    
I'm afraid I don't know which are good. I'd say try something highly rated in the store. It's worth a shot. Is it a specific network, or ALL WiFi? There could be a compatability issue with the router, or just a dodgy internet connection. It's hard to narrow down. –  RossC Jun 6 at 14:04
    
There's an option in WiFi settings that makes Android ignore networks with weak signal. You may want yo confirm this option is off. –  ctt Jun 18 at 0:42
