My Moto G used to connect to my home wireless but now it will connect and about 10 seconds later disconnect. Nothing has changed with my wireless router or anything else so why does it keep disconnecting ? It worked fine for the last few years and I am at a complete loss as to what to do. It says I am good on updates. Please help so I can go back to using my own home wireless. Oh when I connect to other wireless spots it works fine.
Remove power from your router and modem. Wait 10 seconds. Plug in the modem. Wait 20 seconds, plug in the router, wait 20 seconds. Reboot the phone.
If @billg’s suggestion doesn’t bring you back to normal (as it often does)… then consider that maybe a neighbor has added a new router and is riding on top of your previously good signal?
