I recently switched from ATT Uverse (one modem/router unit) to Spectrum (modem provided, bYO router)
My daughter and I had no trouble connecting our laptops and phones to the wifi with Spectrum's network name and password that came with the modem.
Then I bought a new Android tablet and connected it to the wifi in the same manner It worked for a day or two...just long enough to sync with my phone and load contacts and apps, etc. Then it started saying "Authentication Error"
Nothing I do now will get it to connect.
Also got a new phone. Also an Android. Same thing. Will not connect. They are both android devices. Both were able to connect with the wifi at the public library.
I've tried to follow various trouble shooting ideas. Some of them direct me to connect with the ROUTER, not with Spectrum's network name and password that came with the modem. But that doesn't work either.
What am I doing wrong? I'm sooooooo frustrated.
