My Xfinity model XB7 modem developed a wi-fi problem (kept quitting) so yesterday I took it to my local Xfinity store and was given a newer XB8 modem... the wired computer connection was no problem The wi-fi was a problem (not a major problem, but lots of time) The XB7 had two names for the 2.4 and 5 GHz channels... I used the default names, which contained a 'special character' in each name, with my own passwords The XB8 has one name for all 3 channels (2.4 & 5 & 6 GHz) and it will 'negotiate' the best link with any connected device Updating our cell phones was easy by going into the Settings screen to select the new wi-fi name and entering the password Updating our Alexa 'show' boxes was 'almost' as easy, by pressing and holding the MUTE and Volume DOWN buttons at the same time to set the boxes back to factory defaults, and then entering at the prompts on the screen to get linked to the new wi-fi name Similar for Ring doorbell and cameras, by using the cell phone app (press three dots at the device then press the 'red' wi-fi bars to get to a 'reconnect' screen to enter the new information as instructed) Things do happen, so if this modem ever has problems I'll just have to hope that any new modem allows me to enter my name and password for the wi-fi connection, so I won't have to do any relinking (I did enter my name and password in the XB8, but it wouldn't allow the 'special character' that was part of the name in the old modem, so I had to create an entirely new name... hence the relinking)
