Wifi Connection using Xfinity modem

Having problem connecting or holding wireless connection. Some devices like TV have a wireless connection. Others like windows laptop or kindle can't get a connection. Error message on Kindle is --authentication problem. Problems started when wifi could not connect to android cell phone. Got Xfinity to fix that I believe by reconnecting modem with password. I can connect my laptop if I hard wire. Xfinity maintains they fixed problem on their end now its a problem with my devices. I have tried to reconnect network adapter with not luck. Since I have been having intermittent connection with Xfinity could it be my 6 month old Xfinity modem? Any other suggestions for a non tech savy user.

 

Windows Fax and scan Xfinity Voice Modem

I have lost the Dialtone from my Xfinity modem to my Windows fax and scan software in windows 7. Software says connected but, no dial tone detected. what could have caused it to stop? It was working fine. I had a modem upgrade and I haven't had a dial
tone since. While I am waiting on Xfinity which seems to be a continuous effort these days I want to troubleshoot it myself.

I keep getting promised tech support return calls but, they never come. I have an Associates Degree but, I am stumped on this one. Not familiar with changing software permissions and changing things around. Any suggestions or help. Microsoft is an empty
vessel when it comes to windows 7

Phone cord goes straight from Modem to PC. No wall jack, no landline phone.

 

Wifi Connection using Xfinity modem

An "authentication problem" suggests that you're using the wrong password. It's not at all clear what "Got Xfinity to fix that I believe by reconnecting modem with password" implies, but perhaps the Xfinity tech changed your wifi password.

What do you mean by "I have been having intermittent connection with Xfinity"? Are you referring to connecting by wifi with your laptop or Kindle or do you mean that even when you connect to the Xfinity modem by Ethernet (cable) your connection sometimes drops out?

View your wifi password and write it down. See several methods here: https://www.xfinity.com/support/articles/view-change-wifi-password

Now take a look at the wifi password saved on your laptop:

If the password in your laptop is NOT the same as the one you viewed above, change it to match.

While you're at this screen, write down the "Security type" and "Encryption type" should further troubleshooting be necessary.
