 ===== Notes =====
-  * 2021/04/28: Dropping invalid packets (firewall) causes an Oculus Quest 2 to not load it's own store/home page
-  * 2021/04/28: Software Flow Offload causes speed tests on an Oculus Quest 2 to not work at all
-  * 2021/06/14: Enabling ''Use broadcast flag'' causes WAN not to work
-  * 2021/06/29: Enabling ''802.11w Management Frame Protection'' on 2.4GHz caused a NC200 to not be able to connect
-  * 2021/07/02: NoTengoBattery's optimized firmware causes an Oculus Quest 2 to not initiate app update downloads; may be related to Software Flow Offload being enabled by-default
   * 2021/07/02: :!: When using Oculus Air Link and a speed test at 60Mbps download, CPU 0 is around 75% load and the other 3 are 1-5%. Packet Steering is disabled by-default and doesn't seem to do anything when enabled. irqbalance spreads the load quite nicely and drops CPU 0 in the same situation to around 20%. Presumably, if ISP speeds increase beyond 60Mbps, irqbalance will be required.
+  * 2021/08: For 5GHz, the wireless channels chosen needs to do 30 dBm on both 2.4GHz and 5GHz. For 5GHz, 149 works fine.
