My wife has a Macbook Air (2013), Mavericks 10.9.2.
It connected wirelessly on Wednesday, but will not connect wirelessly or via USB Ethernet today (Thursday)
All our other devices (Android and Desktop Windows 8.1) have no problem, either wirelessly or hard-wired.
I have tried a shutdown/restart but still no connection (wireless and USB hard-wired).
System Preferences>Network shows no errors either wireless or USB Ethernet.
As far as I am a know nothing was installed on Wednesday and my wife would not be remotely interested in 'fiddling' with settings she knows nothing about.

All our hard wired devices are using powerline, but I have connected the Mac directly to the Huawei HG659 modem/router (VDSL) in the garage and still no internet access.

This is the first time this has happened since we got the Mac (Sept 2013).

Any suggestions on what to try next?

PC: Dell Inspiron 16 5640 (Windows 11 Home), Dell Inspiron 7591 2n1 (Windows 11 Pro), HP ProBook 470G1 (Windows 10 Pro), Intel NUC7I5BNH (Zorin)
Net: Grandstream 1 x GWN7062 Router, 1 x GWN7665 Access Point
Storage: Synology DS216play NAS, 2 x 6TB
Media: 3 x Amazon FireTV. Echo, Dot, Spot
TV: 2 x Samsung H6400 55" LED TV, Panasonic TH-P50G10Z 50" Plasma TV
Mobile: Samsung Galaxy A52 5G
Wearable: Gear S3 Frontier

Naive question - Does her Mac have a physical wireless on-off switch? (Wintel notebooks often do)
This would not explain the failed Ethernet connection though.
I don't own a Mac but I know they never fail

In System Prefs -> Network, do the connections light up with a green dot?

Clicking in to advanced, is there a valid IP address there?

Are you running IPv6 internally?

1) Green Dot
Both are green - USB Ethernet and Wi-Fi

2) USB Ethernet = 192.168.1.9 (OK by me, Router is 192.168.1.1)
Wi-Fi = 192.168.1.7

3. Not that I am aware of.

Sounds like there is connectivity of both are getting valid IP address in the right range. Have seen an issue a couple of times with it trying to use IPv6 when there isn't a valid route.

Try going in to the advanced settings and flicking IPv6 off

As of now, I am connected via USB Ethernet.
Configure IPv6 is set to 'Automatically' (which I have never touched).
The only 2 other options are: Manually Link-local only

Have you tried turning it off and on again?

Probably not the solution but check location in the apple menu to make sure you don't have two different locations enabled, and you have inadvertently selected a different location setting.

Perhaps, I should re-install Mavericks.
I have, no idea how to do this.
If the recommendations is Google it, then OK, I will.

Create a new user in the users and groups system preferences. See if you can connect from that account. If yes, then there may be a corrupt network file in the main account. I agree that it may be something to do with DNS server settings.
