Information

  • NETGEAR R6260 1)
  • OpenWrt 2) 3)

Notes

  • Stock firmware reports d(149)+p(153)+d(157)+d(161) for 5GHz channels with 153 selected and 11(P)+7(S) for 2.4GHz with 11 selected
  • Stock firmware seemingly has lower pings overall around 0.2ms, compared to OpenWRT
  • :!: Stock firmware seems to randomly drop OpenVPN connections as of 2021/01/12 even with open NAT
  • :!: Software and Hardware flow offloading on OpenWRT both consistently cause SpeedOf.Me to stop mid-test as of 2021/01/13; don't enable either of these settings

Snapshot

sysupgrade

  • This downloads the latest sysupgrade.bin directly 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/ramips/mt7621/openwrt-ramips-mt7621-netgear_r6260-squashfs-sysupgrade.bin'
ping '192.168.1.1'

Date Check

Download

OpenWRT

  • ramips/mt7621
rm -f '/tmp/netgear_r6260-sysupgrade-snapshot.bin' && wget -O '/tmp/netgear_r6260-sysupgrade-snapshot.bin' 'https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/openwrt-ramips-mt7621-netgear_r6260-squashfs-sysupgrade.bin'

SSL Support

  • :!: If wget fails because of missing SSL support, run this
opkg update && opkg install 'libustream-mbedtls'

Install

  • -n doesn't save old config
  • --force forces the flash
  • -v more verbose
ssh 'root'@'192.168.1.1'
sysupgrade --force -n -v '/tmp/netgear_r6260-sysupgrade-snapshot.bin'
