+Plan: Setup wifi adapter to capture Amazon echodot.
+Flow for setting up Access Point:
+1. Setup Access Point
+2. Configure Routing/Bridge or similar so IoT device can access internet.
+
+Tried [linux-wifi-hotspot](https://github.com/lakinduakash/linux-wifi-hotspot) repo. Running it makes AP visible to iPhone, but issue is IP Address. Need to configure dhcp server or manually assign address. 
+
+Problem: Wifi Adapter In monitor mode sees nothing.
+Neither Adapter has driver for modern macos
+Archer T3U is using rtw_8822bu driver from kernel, this supports mac
+
+Decide to go down hostapd route.

 ### Completed:
 - All Devices unpacked except [[xiaomi tv stick]].
 - [[ledvance led strip]] wont enter pairing mode. 
 - [[echodot]] is setup and works.
 - [[mi 360 home security camera]] needs microsd card.
-
 ## Plan for this week:
 - Get microsd card
 - MAINLY: Get AP working or find other way to capture traffic. 
 ## Misc.:
 Much time lost resetting router. [[ledvance led strip]] will only connect to 2.5GHz networks.
 If laptop is connected to internet via ethernet, then I can make a AP, but iPhone wont connect to it. But IoT devices connect

 - __Issue__: After using `airmon-ng` to put my wifi adapter into monitor mode and then supposedly back into normal mode: network manager couldn't find wifi adapter anymore.
 - `sudo nmcli dev` showed that `wlp44s0` interface was "unmanaged".
 - __Fix__: `sudo nmcli set wlp44s0 managed yes`
