Ethernet cuts out on Linksys EA6350v3

Installing and Using OpenWrt

Hold on...

  • that MTU is lower than the minimum for IPv6 (1280); and
  • to be clear, on a 1500 Ethernet link, the MTU for a HE tunnel would be 1480 (i.e. subtract 20 for the header)

Good news! This issue looks to have been fixed in this commit for all IPQ40xx devices:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=678569505623e50bbbbc344c7e820fb315b79ede

I have tested with SNAPSHOT r13684-3b0f698760 and no lock ups while using IPv6

I left the iperf3 IPv6 test running for 30 min with about 75Mbytes/s (one core is 100% IRQ). After installing IRQ Balance getting pretty consistent 110Mbytes/s after it juggles around the IRQ's.

How would one go about adding this fix to a router running latest firmware? Sorry, Iā€™m not familiar with compiling firmware.

  • If you're running the latest firmware, this means it would be fixed, correct?
  • To be exact, please tell us what version you're referencing.

I'm still able to drop LAN connection with my EA6350v3, using 19.07.4, multiple times during my video conference call.

I guess there's some more issues in it.
