I use PPPoE to surf the Internet, but sometimes I can’t surf the Internet. I can resume surfing the Internet after I enter the background of the router and turn off IPv6. But the next time I can’t surf the Internet, I turn on IPv6 and then turn off IPv6 to restore the Internet. It’s always like this. I don’t know if I’m the only one with this problem
very similar syndrome like Flint+IPv6 …
If ipv6 is disabled, will the router be disconnected from the Internet after being used for a period of time?
When that happens, is it only some software applications or all LAN devices that are not connected to the Internet?
This may have nothing to do with ipv6, since the router restarts the network when ipv6 is turned on and off, which may be the key to network recovery.
I have a suspicion that the HW-NAT is causing the problem，can you try turning off HW-NAT and see if this happens？
Log in to the router using SSH and run the following command：
uci set firewall.@defaults[0].flow_offloading='0'
uci set firewall.@defaults[0].flow_offloading_hw='0'
uci commit firewall
/etc/init.d/firewall restart
IPv6 also has issues with B1300.
Internet crawls if you enable it. I keep it turned off.
This is with 3.211beta4 firmware.
