How to fix Internet Connection after upgrade in Kali without IT Access

There is usually little I cant fix on a linux box but I am having trouble with this one. I’m on a 2008 Macbook running Kali-Rolling and after my last upgrade it would no longer connect to internet. The NetworkManager applet still works, still shows my AP etc…But when I click on the AP it tries to connect and just stops…I checked DMESG didnt find anything immediately useful…I tried to go and manually connect via iwconfig also ifup etc…Nothing will work.

Note: I spent much of last night trying to connect via command line using traditional command line techniques and still NOTHING. ALL of my hardware is being detected and working just fine.

It SEEMS like it may be a problem with DHCP?

How can I fix my Internet connection without web access to apt upgrade again?

Update: Tried connecting via the nm-applet like I normally would and it seems to work fine to connect to ANY OTHER wif AP but when I go to try mine it will not connect…I got it to connect to the neighbors guest acct. although without a password im not able to get to the web…Never seen anything like this in 20 years
