2017 Macbook Pro, wifi shuts disconnects every half hour to an hour.

Hello,

Relatively seasoned apple user - about 8 years or so, and never had an issue I couldn't figure out with due research until now, so here I am with this:

I'm running a 2017 Macbook Pro with:

------------------------------------------------

Model Name: MacBook Pro

Model Identifier: MacBookPro14,1

Processor Name: Intel Core i5

Processor Speed: 2.3 GHz

Number of Processors: 1

Total Number of Cores: 2

L2 Cache (per Core): 256 KB

L3 Cache: 4 MB

Memory: 8 GB

Boot ROM Version: MBP141.0175.B00

SMC Version (system): 2.43f6

Serial Number (system): ****

Hardware UUID: ****

------------------------------------------------

The title says it all really but I'm confused. The wifi doesn't cut off intermittently for any other device in the house. Only this one. It's an issue I've had for several months now and my patience is running thin.

Please hear me out when I say I tried the preliminary troubleshoots. Flush DNS, deleting and re-adding the connection via System Preferences -> Network, power cycling the modem, wireless diagnostics showed nothing, everything had no effect.

What could be the issue?

Appreciate any inputs, thanks in advance.

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?

Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:

If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.

If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.

To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.

also, any of these items may be involved:

• Power Adapter cable recall

• firmware update for the Apple Multi-Port display adapters (specifically to reduce interference).

• LG-display recall -- to address Wi-Fi interference so severe, it knocks the Router off the air if too near the Router.

At this point I would suggest running the Diagnostic/AHT http://support.apple.com/kb/HT1509

Not definitive by any means, but may kick out an error code.

This will be a look at potential hardware issues.

A more definitve test would be with Apple store.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test
