Thanks, Bob Timmons
it's my house mate's gateway and undisclosed login credentials so it was hard for me to **** around with it and figure it out, but HERE'S THE FIX SOLUTION WHAT WORKED when i finally got back into the TC this morning (to get the TC on the correct gateway router and IPv4 Address and DNS Servers):
With (see my original screenshots):
- Airport Utility> Wireless> Network Mode: OFF
- Airport Utility> Network> Router Mode: OFF (bridge mode)
I went back to Airport Utility> Internet> Connect Using: Static
I entered the gateway Router Address: 192.168.1.254 (the one i use to log into the router)
I entered IPv4 Address (guessed): 192.168.1.100
Applied and rebooted Mac Mini and TC.
A check suggest that two Macs checked were using IPv4 Address: 192.168.1.100
So I went back to Airport Utility> Internet> Connect Using: DHCP
Then I got NO DNS SERVER error when Airport Utility rebooted
FINALLY
I went back to Airport Utility> Internet> DNS Servers and entered:
8.8.8.8
8.8.4.4
and Applied
After that I was successful in confirming:
- Each Mac was getting on the Internet through the gateway's wireless network
- Each Mac was pointing to the correct ATT gateway router: 192.168.1.254
- Each Mac has a unique IPv4 IP address: 192.168.1.###
At that point it looked like I finally got it right and so far no wireless issues.
