Mid 2012 Macbook Air Wifi Download Extremely Slow

Have macbook pro with same problem cant find solution. Mac goes great without case lid. Put it on and goes slow and fans run at 100 percent by Pablo I'm like 3 years late but I had the same problem with a macbook pro 15 retina mid 2012 i7 2.3ghz and after disconnecting the camera cable the computer started working normal! The 10.11.6 update in particular has proven the worst for slowing down my mid 2012 Macbook Pro – not what I expect when dropping $2,000 on a computer. I have a 2.9GHz Intel chip, with 16GB RAM, and it still runs like a snail more often than not. A thread titled Painfully Slow WiFi on new iPhone 5 on our own forums details some of the problems that have been seen by some customers. Byran85 writes: I just got done setting up my iPhone 5 (as. MacBook Air (2010 and later) MacBook Pro (2010 and later) If your Mac is not among these, trying to use the High Sierra will be very challenging. There will be several issues including lengthened troubleshooting and macOS High Sierra slow. You can try updating the software and hardware for better results. I'm experiencing the exact same slow network speed on my Macbook Air mid 2012. For example when I'm transferring files from my NAS, a Qnap TS-259 Pro+, wirelessly through my D-Link DIR855 router.

The MacBook Air mid 2012 is still a very capable notebook for everyday use. When my wife ordered one in 2012, we thought that a 120GB SSD would suffice, but times have changed and so has the size of IE. digital photo’s. Time to upgrade the SSD!

I got my hands on a brand new WD Blue M.2 SSD 250GB, so I decided to use that one. Now you can’t fit a M.2 SSD in a mid 2012 MacBook Air, but there is a company called Sintech that is creating all kinds of SSD adapters. I ordered a MBA 2012 to M.2 SSD adapter from Amazon and a week or so later it fell on my doormat.

Installing the Western Digital Blue M.2 SSD on te adapter was a bit of a fiddle with what screw to use, but I got it mounted just fine. Luckily iFixit has a full tutorial on how to swap the SSD (not that it is hard), so I followed their procedure and installed the SSD in the MacBook Air.

Obviously I had to reinstall MacOs, but that was easy because created a MacOS installer USB Drive before I started and had a good Time Machine backup at hand which I made on a fast G-Drive EV.

After installing and restoring 155GB of free space again 😀

The MacBook Air 2012 isn’t capable to make full use of the speed of the WD M.2 SSD (it should reach speeds of up to 545MB/sec), but it gave me a much better write speed. Reading was a little bit slower than on the original SSD but personally I think that’s fine.

Wi-Fi problems on macOS Big Sur/Mojave/Catalina

Wi-Fi connection — it is central to intelligent life on Earth. But there could be numerous reasons your Mac won’t connect to Wi-Fi: a new software update, broken Wi-Fi preferences, or several networks conflicting with each other. Below we’ll explain what to do when you can’t connect to Wi-Fi or your connection is constantly dropping off.

So here go the most common symptoms for Wi-Fi problems on Mac:

  • Mac won’t connect to internet, but other devices will
  • Mac connected to Wi-Fi, but no Internet access
  • Wi-Fi connection keeps turning off
  • Slow or unstable Wi-Fi connection on Mac?

Tip: In case your Mac is generally slow, which obviously affects the Internet too, you may start with fixing the performance issues first. The quickest is to delete junk and old caches from your drive and browsers. Here you can download the free version of CleanMyMac app. It helps to remove the unwanted files, bloatware, and junky web browser extensions. In a few minutes, your Mac should be relatively fresh.

Ways to fix Wi-Fi on Mac

Download

Run the default Wi-Fi assistants

To troubleshoot Wi-Fi problems on Mac it’s good to start with native tools that came with your OS.

Go to Apple Menu -> System Preferences -> Network

This window lets you inspect your Wi-Fi preferences. If your Mac has internet connection problems, click Assist me as shown in the screenshot below. This will launch a built-in Diagnostics tool.

Did it solve the problem? Good news there’s another instrument provided by Apple, a Wireless Diagnostics app.
Option + click the Wi-Fi icon in the top right corner
Click Open Wireless Diagnostics…

Delete and reset Wi-Fi network settings

This step will reconfigure your existing Wi-Fi settings and launch your network experience from scratch. But before you begin, we seriously recommend to back your Mac up using Time Machine.

  1. Turn off Wi-Fi and close shut down your browsers
  2. Open Finder -> Go -> Go to Folder...
  3. Paste in the following line:

4. Select the files listed below (as shown in the screenshot)

preferences.plist
com.apple.eapolclient.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
com.apple.airport.preferences.plist

5. Move these files to Trash (without deleting)
Or move them to a new folder on your Desktop.
6. Restart your Mac
Now you will have to revisit Wi-Fi preferences (Click Open Network Preferences under Wi-Fi icon). Turn Wi-Fi on and select your Wi-Fi network again.

The path above proved to be a good remedy in cases when Wi-Fi connection drops off after upgrading to macOS Catalina. If the issue persists, you may consider to clean install macOS Catalina.

Wi-Fi won't turn on after sleep mode on Mac

In some cases, sleep mode settings is the reason your Wi-Fi drops off on Mac and wouldn’t turn on again. Try this simple fix which many users found helpful:

Go to System Preferences -> Energy Saver
Disable Wake for Wi-Fi network option

Check your Wi-Fi now (cross your fingers). Did it do the trick? If not, let’s move on to the next step.

Flush DNS cache

Another way to fix Mac Wi-Fi not working is to flush your DNS cache. DNS service helps your Mac find IP-addresses, much like in a phone book. It has a cache folder of its own. Removing these cache files is helpful when your Wi-Fi slows down at random or you can’t access certain websites.

To save you from meddling with critical system folders, here’s a quick workaround.

1. Download DNS Flusher (it’s built into CleanMyMac X — get it here).
2. Go to Maintenance tab and tick Flush DNS cache

That’s all — and this solution is 100% free and takes no more than a minute.

By the way, CleanMyMac X is pretty much an indispensable tool if you want to keep your Mac clean and junk-free. It removes up to 74 GB of junk files on an average Mac, so give it a spin, just in case.

Reboot your Wi-Fi router

Plug off your router and leave it for a minute or two. This way you will know if your Mac won’t connect to Wi-Fi because of router issues. Plug your router back in and try to connect other Wi-Fi devices in the room.

Additionally, try placing your router in a different place. Your Wi-Fi signal could be lost due to neighboring network or it is catching a “dead-zone” in your house. If your room allows it, move it right in the center of the room. Fewer barriers, the better signal.

Still no Wi-Fi connection on Mac? Switch off the Bluetooth

Bluetooth devices often interfere with Wi-Fi, especially if the Wi-Fi signal is weak. It’s because both rely on radio frequencies to work. So one more idea to fix your Wi-Fi not working on Mac problem is to inspect the Bluetooth settings.

Try disconnecting the Bluetooth and see if the problem persists.

Go to Apple menu -> System Preferences
Select Bluetooth
Then click Turn Bluetooth off

Update your router firmware

If you are using Apple Airport router you’ll need Airport Utility to perform the update. Obviously, this step requires an internet connection. You can connect via cable if your Wi-Fi doesn’t work on Mac.
Go to Applications
Type Airport Utility in the search bar

You’ll see your Airport base station. If you see a red notification badge next to the base name, click it for more details. If the update is available, the app will show you the Update button.

Customize MTU and DNS settings to fix Wi-Fi on Mac

Macbook Air Slow Internet

MTU stands for Maximum Transmission Unit and describes the packet size that is exchanged via the network (measured in bytes). The solution described below implies lowering MTU size which should make your WI-Fi connection less laggy. While customizing DNS location has also proved effective to solve even the most bitter Wi-Fi problems on Mac.

But don’t let these geeky terms put you off. The path takes just about a minute and you’ll be proud to have fixed your Mac Wi-Fi not working, the Apple Genius way.

Step 1.

Go to System Preferences -> Network
Select Wi-Fi in the left panel
See Location menu on top
Click Edit Locations…

Step 2.
Now create a new location by clicking [+] plus button. Name it anything you like. Click Done.

Step 3.

Then choose your standard Wi-Fi connection under Network Name
Click Advanced
Go to TCP/IP tab and click Renew DHCP lease .

Step 4.

Go to DNS tab and by clicking [+] buttons enter 8.8.8.8 and 8.8.4.4 as IP-addresses, each in a separate line. These two are Google’s alternative DNS servers that the company recommends using — they are safe. But before you do this, make sure to copy your current DNS address on a piece of paper.

Step 5.

Go to a Hardware tab from the previous step.
Under Configure dropdown menu select Manually
Click MTU and set the custom size of 1453
Click Apply

Well done. Your Mac Wi-Fi not working should have been resolved.

Still no or poor Wi-FI Connection on Mac?

Maybe all this time you’ve been digging in the wrong place as the problem is in your Mac itself. It might need some basic tidying up and maintenance to run faster. Try giving it a full clean with a tool like CleanMyMac X (it's my favorite among similar Mac tune-up apps — here's the official free download from the developer site). Hopefully, once your Mac is clean and up to speed again, your Wi-Fi should get back to norm.

May the Wi-Fi be with you. Thanks for reading.
