[Solved] Linksys WRT3200ACM Alexa Echo not working

[carlosdico]

Hello everyone,

I recently flashed OpenWrt on my Linksys router and I'm having a persistent issue with my Amazon Echo Dot devices. They are unable to connect to the 5GHz network.

The weird part:

• With the stock Linksys firmware, all Echo Dots connect perfectly fine to the 5GHz band.
• After switching to OpenWrt, they simply won't connect. They see the SSID, accept the password, but then fail during authentication / IP assignment.
• I have tried the following without success:
  • Setting channel width to 40MHz (also tried 20MHz and 80MHz)
  • Using WPA2-AES only (also tried mixed modes)
  • Manually setting the country code (correct one for my region)
  • Disabling 802.11r/k/v fast roaming
  • Setting the authentication to WPA2-PSK exclusively
  • Different channels (36, 40, 44, 48, 149+)

I don't know what else I can try. Any suggestions?

Thanks.

Echo supports only A/N, it is best kept in 2.4GHz cespit.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):

Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Thank you very much for your help.

I finally found the problem. It was a configuration mistake on my part: the WAN interface in /etc/config/network was named wanNet , but in other sections of the configuration (firewall, zones, etc.) it was still referenced as wan .

Because of this mismatch, the PPPoE connection was established, but the firewall and routing weren't properly linked to the interface, causing connectivity issues for LAN devices.

Once I renamed the interface from wanNet to wan and rebooted the router, everything started working perfectly. All devices connected, and internet access was restored.

For reference, here is my working WAN configuration:

config interface 'wan'
        option proto 'pppoe'
        option device 'wan.20'
        option username 'xxxxxxx@xxxx'
        option password 'xxxxxxxx'
        option ipv6 'auto'
        option norelease '1'
        option ifname 'wan.20'
        option mtu '1492'

Thanks again for your time and suggestions!

Odd, must depend on generation of their devices. I've seen dots using AC.
