Converting your AR-150 to a WiFi Pineapple NANO should be an easy process. However, the web & git is full of broken bin images and botched firmware builders... resulting in a broken or partially-working firmware. The latest working build available elsewhere is 2.4.2. Here, we start with version 2.5.4.

Summary for 2.5.x:

1. Rootfs 2.6M
2. PineAP(d) working.
3. Drivers for: kmod-rt2800, kmod-rtl8187 and kmod-rtl8192cu (TL-WN7200ND, AWUS036H, based on RT5370, etc)
4. Kernel 3.18.84

Summary for 2.6.x:

1. Rootfs 1.6M
2. PineAP(d) working.
3. Drivers for: kmod-rt2800, kmod-rtl8187 and kmod-rtl8192cu (TL-WN7200ND, AWUS036H, based on RT5370, etc)
4. Kernel 4.14.134
5. Fix LAN and WAN ports. No more swapped ports.

Recomended setup

1. USB 2.0 2 ports hub https://www.ebay.co.uk/itm/USB-2-0-2-Dual-Port-Hub-For-Laptop-Macbook-Notebook-PC-Mouse-Flash-Disk/273070654192
2. Generic RT5370 adapter
3. Please support Hak5 work and buy the original hardware

Notes:

1. For format jffs2 (overlayFS) use jffs2reset command.
2. If you are stuck at the message "The WiFi Pineapple is still booting" don't panic, this is a known issue with running the WiFi Pineapple firmware on the AR150. All you have to do is ssh into the AR150 with the username root and password you set originally when you booted the AR150 right out of the box. Executing the command jffs2reset -y && reboot should resolve your problems.
