Cannot connect to to WiFi networks

[Android Central Question]

I used to have no problems connecting to WiFi at home and when out but now it doesn't work. I have had the phone for two years.

Welcome to Android Central! Which phone? Are you saying it doesn't connect to any wi-fi network now, or only your home network?

Having the same issue on my galaxy S7 over the last couple weeks. It auto connects to my home wifi, but can't connect to my secured wifi at work, which I have the correct password for, and no public networks either. I've reset my network settings, had my phone forget my work wifi and reconnect several times. Nothing is working.

Does your work wi-fi require a password to even connect to (i.e., is there a lock icon associated with the wi-fi icon in your wi-fi settings), or is it an open network to connect to but then you have to enter your credentials in a login screen?

Work Wifi requires a password to connect.

The issue with your work WiFi might be that they updated the security settings, a lot of places are going to this even open networks, it not only required you to connect, either through an open log in, user and password or just a password, and then agree to terms and conditions. Often if you simply open a web page you'll be redirected to an agreement page where you'll have to agree to whatever terms they've laid out. It's mostly covering their butt so you can't sue if your data is hacked or your IP is used for some malicious propose. Check with your IT department and see if they've put something like this in place. I had an issue where I couldn't connect to an open network until I logged into Facebook as a security measure.

As for the OP and their home network, if your home network has internet connection, which you can verify with the lights on your router or possibly another device, turn off the router, usually unplugging it, and wait about 1 minute to allow all the power to dissipate before turning it back on. I've had issues where I'm connected but don't have access. It seems like a hiccup or something and then it comes back. I think it's more than likely in the router because you mention that it went out and then you started having problems, plus you've reset your options on your device. I would suspect where the activity was, which would be the internet itself going out making the issue most likely at the router.

Hello,

We haven't done anything different with our work wifi. Others in the building aren't having any issues. We're a small company so when we make changes we know about them quickly. I'm not just having trouble with my work wifi network I've also been unable to connect to public wifi as. I've tried a couple restraunts and am unable to connect to their networks.

Any wi-fi manager apps installed? Have you also tried going to Settings>Security>Clear Credentials​?
