If you’re stuck wondering what to do if MacBook keeps losing WiFi etrstech, you’re not alone. It’s a frustrating issue that can interrupt work, video calls, or a late-night binge. The good news? There are practical fixes. This guide covers both the simple tweaks and deeper system checks that can get your connection back and keep it steady. For a comprehensive breakdown, check out what to do if MacBook keeps losing WiFi etrstech.
Start with the Basics
Before diving into the gritty details, knock out the basics. Simple errors can trigger even the most persistent connectivity problems.
1. Restart Your MacBook and Router
This sounds obvious, but it’s a classic for a reason. Restarting both devices can clear temporary glitches. Unplug your router, wait 30 seconds, then power it back on. Restart your Mac once the network is running.
2. Check Other Devices
Is your phone or tablet also struggling to connect? If yes, your WiFi network may be the issue—not your Mac. If everything else works fine, your Mac might need some TLC.
3. Forget and Reconnect to the Network
Head into your System Settings → Network → WiFi. Select your network and choose “Forget This Network.” Then, reconnect by entering the password again.
Dive into System Settings
If quick fixes don’t cut it, it’s time to update some settings and poke around under the hood.
1. Check Your DNS Settings
Wifi drops can sometimes be traced back to sluggish or unresponsive DNS servers. Try switching to Google’s (8.8.8.8 and 8.8.4.4) or Cloudflare’s (1.1.1.1). Go to System Settings → Network → WiFi → Details → DNS and manually enter these.
2. Reset Your Network Preferences
This erases outdated or corrupt configuration files that might be interfering with your connection. To do this:
- Open Finder
- Go to
/Library/Preferences/SystemConfiguration/ - Move the following files to your desktop as a backup:
com.apple.airport.preferences.plistcom.apple.network.identification.plistcom.apple.wifi.message-tracer.plistNetworkInterfaces.plistpreferences.plist- Restart your MacBook
macOS will generate new ones when the system boots back up.
macOS Updates Matter
Apple rolls out regular updates to fix bugs—including network issues. If your operating system is outdated, that could be the root of your dropped connections.
Here’s how to update:
System Settings → General → Software Update → Install if any update is available.
After updating, monitor your connection. Some updates fix small bugs that aren’t even mentioned in the release notes.
Location and Interference Problems
Sometimes, the issue isn’t in software—it’s in your environment.
1. Move Closer to the Router
Walls, floors, and even microwaves can degrade your signal. Distance makes a difference, especially on 5GHz networks with shorter range.
2. Change the WiFi Channel
Most routers default to certain channels. When too many routers use the same one in a crowded space (like apartments), signals overlap and performance suffers. Login to your router settings and try switching to a less congested channel.
3. Reduce Interference
Household devices like cordless phones or baby monitors may knock your connection. Keep them away from your router and MacBook when possible.
SMC and NVRAM Reset
The System Management Controller (SMC) and Non-Volatile Random-Access Memory (NVRAM) hold important low-level settings. Resetting them can help eliminate persistent WiFi hiccups.
To reset the SMC:
- Shut down your MacBook.
- Hold Shift + Control + Option + Power button for 10 seconds.
- Release all keys and turn the Mac back on.
To reset NVRAM:
- Turn off your Mac.
- Turn it back on and immediately hold Option + Command + P + R.
- Hold for 20 seconds.
After resetting, recheck your WiFi settings.
Create a New Network Location Profile
Sometimes, creating a new network profile is the magic move. This refreshes the way your Mac manages its interfaces.
Here’s how to create one:
- Open System Settings → Network
- Click the dropdown next to ‘Location’ and select ‘Edit Locations’
- Click the ‘+’ button to create a new one
- Name it and click Done
- Now reconnect to your WiFi and test the connection
When All Else Fails—Consider Hardware
Nothing’s working? There’s a chance this is a hardware issue.
1. Run Apple Diagnostics
To check if your WiFi hardware is at fault, restart your Mac and hold the D key. Follow the prompts to run network diagnostics. If a hardware problem turns up, it’s time to call Apple Support or visit a Genius Bar.
2. External WiFi Adapter
As a last resort, you can use a USB WiFi adapter. It’s not ideal, but it can sidestep internal hardware disputes if you’re waiting for service.
Don’t Let Dropped WiFi Rule Your Workflow
Now you’ve got a reliable checklist for what to do if MacBook keeps losing WiFi etrstech. Most issues come down to a bad setting, interference, or outdated software. Tackle it step by step. Start simple, escalate slowly, and don’t ignore the environment you’re in.
