Recently, I upgraded my Mac to Monterey (15.0.1) and lost Internet connectivity.
Below is what I can do with my Mac :
Below is what I cannot do :
I have tried all the suggestions I could find, but could not resolve the issue.
Not sure if anyone else is having the same issue and/or managed to solve the problem, but appreciate if someone can help with this challenge.
Hi @awte . Does your Mac have ethernet port or only wifi?
You have AV500 extender. What is the model of the other extender? AC1200 is not a model number.
Is the VR1600 used in normal config or in bridge mode?
Is the VR1600 Internet light on?
Suggest to get the VR1600 working properly. Have you rebooted it or tried factory reset?
Then reconnect each extender.
Depending on how each extender connects to VR1600, part of it might be broken.
Thanks for your speedy reply !!
Please find below answers to the questions ...
A very curious situation. Not sure if the AV500 or VR1600 needs patching.
Thanks again for your response !!
@awte . When the Mac is connected to RE305, check its ip address. Use a Windows laptop connected to VR1600 or Powerline to ping the Mac. This should work.
Move the Mac to the other wifi, the one the Windows laptop is not on. Did the Mac get a new ip or keep previous one?
Ping whichever one the Mac is showing. Did it work?
If not, must be related to change in Monterey. Can you check the settings of the wifi adapter on the Mac? Compare with the old Mac.
Reboot the Mac and see if it gets internet.
There are hits for this problem on the internet but nothing from Apple.
Thanks again for replying !!

Some more information ...
A really baffling issue ...
@awte . You mention a gateway on 10.x.x.x. Is that what the VR1600 calls its default gateway?
Do the extenders replicate the VR1600 SSIDs or do they create their own?
Can the new Mac ping the router 192.168.1.1 from various locations using its wifi?
Can the old Mac and the other devices move freely between VR1600 and the extenders?
Have you checked the VR1600 system log? Its DHCPD component might indicate something. And Network, LAN Settings, Client List.
Is the DHCP function disabled on the extenders?
@awte . On VR1600, set the dhcp lease time to 20 minues. Connect new Mac to RE305. Everything should work.
Move new Mac to VR1600. Wait for 10 minutes (if it is like Windows) or wait 20 minutes for the lease to expire. Look at system log to see when this happens. Check if behaviour is different.
Then put lease time back to normal.
Thanks for replying.
I have managed to resolve the issue. It appears that something messed up one of the configuration files (com.apple.airport.preferences.plist) in /Library/Preferences/SystemConfiguration.
Below are the steps I took ...
The above steps re-established Internet connectivity from both the VR1600 and Powerline networks.
Thanks again for your help. It was deeply appreciated !!
