Wireless 2.4 GHz stopped working firmware RT-AC68U_380.57_0

Hi,

Yesterday I upgraded the firmware to RT-AC68U_380.57_0, but I had a problem. The wireless on 2,4Ghz stopped working.

Situation:

• 2.4 GHz
  • SSID: OoloO
  • WPA2 enabled
• 2.4 GHz Guest
  • SSID: OoloO Free
  • Open
• 5GHz
  • SSID: 0olo0
  • WPA2 enabled
• 5GHz Guest
  • SSID: 0olo0 Free
  • Open

The wireless link works and the DCHP works fine. But when the client on any of the 2.4GHz networks try to connect to anywhere the arp request for the router IP did not have any response. I only saw the arp request without any reply.

I have QoS set manually with my own rules, but it worked fine since two years on different versions of the firmware, so I think that it is not the problem

I reset the configuration to default and start to configure manually again, everything worked fine until, my last step, I enabled the Guest Networks, and both SSID stopped working (only 2.4GHz, the 5GHz networks was still working fine)

I rolled back to RT-AC68U_378.56_2 and started working again.

I don't know what is the best way to report a bug, but that's what I can do.


MORE confs: PPPOE, DHCP, no VPN, no IPv6, no special firewall rules only the default check to enable the firewall, no parental controls and no MAC filtering on the wireless configurations (guest and no-guest).

It's a known issue that 2.4GHz breaks if CTF is disabled on the AC68U with 380.57. The new 380.58 alpha/beta fixed the issue.
