If you’ve updated your Mac to macOS Sequoia and the WiFi isn’t playing nice, I’m here to help. Let’s keep this simple. You might be thinking, “I’ve restarted everything—my Mac, my router, my hopes—still no fix!” Well, there’s hope yet. I’m going to show you some straightforward tricks to get that internet back.
So, macOS Sequoia is new. But like anything new, it’s got a few bugs. People, like you, are finding that their WiFi disconnects randomly. One minute you’re online, the next—poof—nothing. Here’s a direct quote from someone facing this:
“After installing Sequoia, my internet randomly drops for 30 seconds at a time. Black screen, ‘server busy’ messages—then everything’s fine again.”
Sound familiar? Here’s what you can do to fix it.

Solution 1: The ESET Fix
If you have ESET antivirus on your Mac, this might be where the trouble’s coming from. A lot of users didn’t update it before installing Sequoia, which is causing the internet issue. Let’s fix that:
Remove the Network Filter
- Go to System Settings > Network > Filters > Remove ESET Network.
- Restart your Mac, then update ESET to its latest version.
Uninstall and Reinstall ESET
- Use the uninstaller that came with ESET to remove the old version.
- Download the latest version from their website and reinstall it.
Solution 2: Add App to the Firewall
Another thing that’s been helping folks is adding the app you’re using (like Firefox or whatever) to the Mac’s firewall. Here’s how:
- Open Terminal.
- Run this command to list your installed apps: /usr/libexec/ApplicationFirewall/socketfilterfw –listapps
- Now, add the app causing trouble (replace “appname” with your app’s name): /usr/libexec/ApplicationFirewall/socketfilterfw –add /Applications/appname.app
- Example for Firefox: /usr/libexec/ApplicationFirewall/socketfilterfw –add /Applications/Firefox.app
- Check if your internet’s back to normal.
Sometimes, fixing tech problems can feel like chasing ghosts. But don’t give up. One of these fixes should work. If not, it’s probably time to contact Apple Support (or throw your Mac out the window—not that I recommend that).
