How do I get rid of popups on phones that log onto home WiFi?

[AC Question]

I, along with current visitors at home, log onto the wireless internet network at my house, and when they try to use the internet, they get lots of popups just because they're going on the internet through the WiFi. How do we stop this? I already tried calling our provider Cox and they said to get McAfee on our devices including phones and that the popups don't come from the internet connection itself. The popups basically prevent us from using the internet on the phones, there are so many. e

Welcome to Android Central! What are in the popups? Are they ads? Does this occur no matter which device is used? What sites are being accessed? There's really no reason for your particular wi-fi router to cause a lot of popups to occur--it usually has to do with particular websites, or possibly some kind of adware that was unwittingly installed on the phone.

I asked the original question and for some reason I cannot reply on my phone...the owner has blocked access to the site, based on the response? I just tried on the computer now and it didn't work with the full url included so maybe that's why. I added spaces so it isn't picked up on this reply attempt.

Now I am told people cannot get anywhere on the internet. The popups happen when phones are connected to only the cell phone network, too, now. It happens on any device now, including computer, iPad, and iPhone. Before I have gotten them that say adcash on my laptop and my phone. The content of the popup windows is a blank white window and the url is data: text/ html, <scri pt> window. close(); </scri pt>

Does this persist on those devices when they use them outside of your wifi network? If the popups are occurring even on mobile data, after the user first connected to your wifi and then turned off the wifi connection, then I'd wonder about some kind of malware that was spread to their device from your wifi network. I'm not knowledgeable about malware to know how possible this is, though.

Yes, the popups started happening after disconnecting from the wifi and using the mobile data. One person got an ad-blocker app on her phone to stop the popups. I was able to find out the urls that flashed across the top of the popup windows very quickly, ending in the url I last posted. They included mobilegameswinner . com, gadget-promotions . com, adnetworkperformance . com, rdsrv . com, loading-page . net, apple . com-verifiedsatus.com/US/iphone6s/i . html.

It obviously seems that the popups come from being connected to our wifi network.

Additionally, I just tried my own phone, a Samsung Galaxy Core Prime, on the wifi, and I got the same popups, but I don't have them when I turn wifi off and browse on just the mobile data.

It's possible for a router to get malware, so you might want to try reinstalling its firmware.

Worm (Network virus) is possible. You could try checking if there are no custom settings placed on your router. Additionally, restarting or resetting it might help, but as B. Diddy mentioned, most likely a firmware rewrite is going to be needed.
