Information

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 (Comcast/Xfinity)
  • 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.

Snapshot

sysupgrade

  • This downloads the latest sysupgrade.bin and installs it
ssh 'root'@'192.168.1.1'
rm -f '/tmp/sysupgrade.img' && sync && sysupgrade --force -n -v 'https://downloads.openwrt.org/snapshots/targets/ipq40xx/generic/openwrt-ipq40xx-generic-linksys_ea6350v3-squashfs-sysupgrade.bin'
ping '192.168.1.1'
rm -R ~/'.ssh'

Packages

  • nano is used to enable irqbalance
ssh 'root'@'192.168.1.1'
passwd
opkg update && opkg install luci irqbalance nano && sync

irqbalance

nano '/etc/config/irqbalance'
        option enabled '1'

LuCI

Startup

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

echo 'performance' | tee '/sys/devices/system/cpu/cpufreq/policy0/scaling_governor' > '/dev/null'

exit 0

Verify

echo 'performance' | tee '/sys/devices/system/cpu/cpufreq/policy0/scaling_governor' > '/dev/null'
cat '/sys/devices/system/cpu/cpufreq/policy0/scaling_governor'
cat '/sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq'

snapshot images don't include LuCI, so it needs installed on every clean snapshot install
