opkg update && opkg install irqbalance luci-app-advanced-reboot luci-app-sqm luci-app-samba4 block-mount kmod-usb-storage kmod-usb-storage-uas kmod-usb-ohci kmod-usb-ohci-pci luci-app-hd-idle kmod-usb3 kmod-fs-ext4 nano openvpn-openssl luci-app-openvpn luci-app-watchcat luci-app-statistics

Below are my WRT1900ACSv2 configurations for improved WiFi performance, kept from rc2:

  • Installed irqbalance. Change 'enabled' from '0' to '1' in '/etc/config/irqbalance'. Essential.
  • Enabled SQM. Significant improvement.
  • Disabled 802.11w (previously known to provide issues on mwlwifi). May not be necessary.
  • Patched firmware-88w8864 mwlwifi specific high latencies by disabling tx_amsdu. Essential. Add in luci > startup > local startup (nano /etc/rc.local) the following commands:
echo "0" >> /sys/kernel/debug/ieee80211/phy0/mwlwifi/tx_amsdu
echo "0" >> /sys/kernel/debug/ieee80211/phy1/mwlwifi/tx_amsdu
