wifi invalid password

I recently set up a router in a new apartment. It connects fine to my phone and one laptop but keeps saying "invalid password" when I try to connect my other laptop. I have rebooted the router multiple times and made sure the password is correct but am still getting the issue.

Hello, @user_c8d58f! Thanks for meeting us here in our community! We are sorry to hear about the trouble with the new modem, but glad to help. Is this a rental modem or your own purchase? Are you trying the connection by Ethernet cable as well or just by Wi-Fi?

@XfinityLinda​ Hi, thanks for the reply! This is a rental modem and I am not using an Ethernet cable.

Something I have done when having a problem like yours is to temporarily save your password as a text file then copy/paste the text into the password field. I use a password generating utility to create a password with the correct number of alphanumeric characters and permitted non-alphanumerics. Copy and paste that somewhere, I use a removable device.  That eliminates any chance of a typo.

The issue is not with the router its with your password manager on laptop. Check to see if you need any updates. Check your saved passwords. There may be one from old set up that is conflicting. If you have a saved password on laptop for xfinity wifi erase it.

@user_482455​ I’ve forgotten all my old networks and I’ve connected just fine to several new networks recently (in different locations). I’ve tried numerous times to reset different settings on my MacBook, but nothing has worked. Could the cause be that my Mac is way behind in software updates? Is there any way around this?

I recommend ensuring the MAC book has the latest update available as the Wi-Fi driver may be outdated. Do you know if your Wi-Fi network is set to auto combine the 2.4 GHz and 5 GHz network or do you see both available? Does the MAC book support 5 GHz? Have you attempted updating your Wi-Fi password and SSID after deleting the connection from your networks list and then reconnecting?
