Acer V3-772G upgrade to Intel 7260 AC WiFi

Here i show you how i upgraded the built in WiFi to the Intel 7260 AC WiFi.

My main reasons for the upgrade:

I wanted to take full advantage of my Routers (ASUS DSL-AC68U) 5Ghz capabilities to escape the overcrowded 2,4Ghz band and:

 - Reduce loading times of photo's stored on my Synology NAS

 - Reduce the time it takes for creating Laptop images/backups to my Synology NAS

Laptop Model: Acer V3-772G, running Win10 Pro 64bit

Old WiFi card: Atheros AR5B22, 2,4Ghz, & 5 Ghz PCIe Half Mini Card

New WiFi card: Intel 7260HMW AC WiFi, 2,4 Ghz & 5 Ghz Dual-Band, Bluetooth 4.0, PCIe Half Mini Card

1.

Download the latest drivers for the Intel 7260 AC WiFi card for your Operating System from the Intel webpage.

Two Packages are needed:

 - WiFi Driver (search for "Intel® Dual Band Wireless-AC 7260" on the Intel webpage)

 - Bluetooth Driver (in the list you get from the search above, scroll down to find the Bluetooth drivers)

2.

Make sure you are electrostatically discharged when handling your devices. E.g discharge by touching the metal surface of earthed appliances.

3.

Allocate the 9 flathead screws holding the cover.

12.

Boot up your system and install the Bluetooth and WiFi driver.

Connect to your WiFi Network.

Go to your Network settings and make sure your WiFi is connected with "ac" speed.

On Win10:

 - Right click on the Windows logo on your taskbar

 - Left click on Network Connections

 - Right click on your WiFi connection - Status

I've made a Speed test by copying a 14.2 GB video file, stored on the Synology NAS to the Laptop.

The NAS is connected via network cable to the ASUS DSL-AC68U router.

Conclusion:

Surprisingly, the WiFi ac connection of the Surface Pro 4 underperformed, it is even a little bit slower than the old Atheros N connection with 300Mbit i had on the Acer Laptop.

If you have no other chance, e.g. are not able or are not allowed to drag Ethernet cables everywhere, the way to go is upgrade to WiFi ac.

For most home or office use pattern and video streaming it is a good solution.

When you are serious about gaming, or have time critical tasks, always go for a wired connection. So you can be sure no neighbor WiFi interferes your WiFi. Also the ping times are usually the lowest on a wired connection.

The upgrade is definitely useful for me, but reaches in no way the performance of a wired Gigabit Ethernet connection, or even the transfer-rates advertised. I am sure the drivers will improve the performance in future.

Cheers.
