Hi, I have two Macs, one in a home recording studio and one for other use. On one of the Mac’s, iMac from late 2022 (OS 10.9 Mavericks), my internet does not work since yesterday. Wifi connection is good. Both browsers, Safari and Firefox are not able to do anything. My other Mac the internet is fine. Does anybody have any idea what the problem could be?
iMac 24″, macOS 12.2
10.9 Mavericks will not run on a 2022 Mac.
It will run on Macs below
OS X Mavericks - Technical Specifications
up to October 15, 2014. All newer Macs can't run Mavericks.
Incidentally the minimum requirements for El Capitan are the same as Mavericks.
That said, Apple menu -> About This Mac will tell you what you are actually running.
The System Report or Profile in the About This Mac window will give you a Machine ID such as iMac x,y.
The x,y value will help us identify which Mac you have if the About This Mac does not.
Apple menu -> System Preferences -> Network will let you determine if you have ethernet or WiFi connectivity. You may need to adapt to ethernet from thunderbolt if present to connect to your modem if the above port is not present.
WiFi connectivity also known as Airport connectivity may fail on 5 Ghz but work on 2.4 Ghz. This can be the case if your WiFi adapter is another room. Check there is send/receive data in the WiFi router happening. If the lights are off, you may need to power cycle the modem first and the WiFi router once the modem shows it has internet. Sometimes the modem and WiFi are the same box.
You can also sometimes make your cell phone into a WiFi hotspot. Let us know if you have an Android or iPhone and we can help you set that up if needed.
Under advanced settings in the Network panel, if the connection is active but only giving you a 169.x.x.x internet address the DHCP lease may need to be renewed. Turn off all proxies, and VPN. The only reason to use VPN is if you are connecting to a school or corporate network where they control the network traffic. In which case, their technical support needs to be contacted to ensure your connectivity is successful.

Hard for me to follow with my age butting in, but see if there are any clues here...
Are you running any VPN, Anti-Virus, or Cleaning apps?
This may look difficult to some but is pretty easy taken step by step...
In Ventura exchange Sys Settings for Sis Prefs...
Make a New Location, Using network locations in Mac OS X ...
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.
If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.
System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
8.8.8.8
8.8.4.4
1.1.1.1
9.9.9.9
Apply.
Aha, I should've thought of that, good find, it won't hurt to try...
https://appletoolbox.com/flush-dns-cache-mac-os-x/
The DNS cache will automatically be flushed, but you won’t see any prompts with Terminal confirming that the process has been completed. Instead, after the DNS flush is finished, Terminal will move to a new line item, at which point the command will have been carried out. In the event that you type the password into Terminal but don’t see the cursor move, don’t be alarmed. This is just how Terminal operates, and as long as you enter the password correctly, the DNS cache will still be taken care of. If you enter a wrong password, Terminal will tell you as much, allowing you to re-enter the password or requiring you to enter the command again.
Ok, I have followed the steps as detailed below here …
1. System Preferences>Network>Location>Edit Locations, little plus icon, give it a name. - I called it “DBAqua1”
2. System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose “Set Service Order.” The interface that connects to the Internet (Wi-Fi) should be dragged to the top of the list. - Done.
3. System Preferences>Network>highlight the Interface you're using (Wi-Fi) >Advanced>TCP/IP>Configure IPv4: Using DHCP. - It was already set like this.
4. If using Wifi, instead of joining your Network from the list, click the “WiFi” icon at the top, and click join other network. Fill in everything as needed. - I am joining my network which is already selected in the list.
5. System Preferences>Network> choose interface (Wi-Fi) >Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS. - None were set.
6. System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet (Wi-Fi), click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
8.8.8.8
8.8.4.4
1.1.1.1
9.9.9.9
Then click “OK”. - I did this.
At the bottom right of “DBAqua location” window click “Apply” - Done.
The results are pretty much the same as it was in the automatic location. It does let me go into my emails in FireFox now so it is a bit better but not a lot. In Safari I can only go to the Google home page. In FireFox I can go to a few other places but it’s still really slow. In conclusion this has not fixed it. Could it be a virus? Could it be damage to the computer due to the power cut? Are there any other possibilities? Thanks again.
OK, in Terminal type...
ping amazon.com -c10
And paste the output, like...

Hmmmm? It appears it did allow it???
Anyway, the ping shows it is getting out to the internet.

Does it get you anywhere?
OK, I fully understand typos.
there are steps to take; as a start.
power off the back on your modem and router and retest
Forget the offending network and rebuild it from scratch
Try a simple restart
Do a safe mode start: Start up your Mac in safe mode - Apple Support
let it sit for maybe 10 minutes the restart normally
If all ease fails, you might consider reinstalling the OS.
When you Option key hold down the menu for the WiFi does it say that you are connected to your known WiFi network and secured on WPA2 encryption? Cause if it doesn't you may have inadvertently connected to a neighbor's WiFi that is blocking network access.
OK, if that doesn't work, open Network Utility>Lookup tab?>mazom.com
Do you get...

amazon.com -> 54.239.28.85, 52.94.236.248, 205.251.242.103
TX Rate : 6 Mbps is terrible slow!
Try forcing/setting your Wifi to use the 2.4 GHz mode for a test.
Great, let's try Wifi again...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
How old is the computer?
http://checkcoverage.apple.com/ can tell you. Do not give us the serial number as that is personal information.
If older than 4 years, reset the SMC.
If it is younger the 4 years, reset the PRAM (connected a wired keyboard to your Mac if it is not a laptop, if it is a laptop, use the built-in keyboard), and hold command-option-shift-R through a restart (PC keyboards use Windows Logo key for command, and Alt for Option). The machine may chime or a light may blink each time it is reset. If you get light or chime feedback, you can wait up to 4 feedbacks before letting go and starting up.
If after a reset there is no WiFi detected, it may be that the WiFi on the computer is damaged. You may need to get an ethernet adapter and connect your Mac to the modem.
If you think it's a Wifi issue. Why don't I try connecting to the router with a cable? There are a few ways I could do it. The easiest would be Ethernet to an Ethernet to USB-C adapter, which I needed to get to transfer the files from my last Mac on to that one. Surely that would eliminate Wifi from our enquiries?
It doesn't seem like it's a Wifi issue as the Wifi graphics show it to be working. Are there any other possibilities?
Find out if your BT router has a 2.5 Ghz network, in addition to a 5 Ghz broadcast. 2.5 Ghz works better between floors than 5 Ghz. Ask BT if there is a way to specify which network your Mac is on. They can look at your router 192.168.1.246
Sorry for not explaining it well enough...
4. If using Wifi, instead of joining your Network from the list, click the “WiFi” icon at the top, and click join other network. Fill in everything as needed. - I am joining my network which is already selected in the list.
So did you still use join Other?
Choose Join Other, but click on yours in the list, we just want to skip the steps where it auto joins it in the background.
The Other in this case will be yours!
