You're reporting on an Atheros device in the Broadcom forum, but while we're here:

I don't think development of that App is current(?) and it may have to do with changes in SSL/dropbear/httpd. If the App doesn't support ED25519, then it's dead.

The issue should be directed to the App's support page:

https://ddwrt-companion.app/

May also require host keys to be removed if juicessh or other ssh client for Android does not support ED25519:

May not be a good idea: revert the host key to RSA using custom /jffs/etc/sshd_config? Smile

Errors could also be reported via the app's page in Google Play!

Router/Version: Netgear R7000
File/Kernel: DD-WRT v3.0-r52020 (03/14/23)
Previous/Reset: Reset
Mode/Status: Access Point only
Issues/Errors: Wifi devices do not want to connect to it when other APs using the same SSID are present

Factory defaulted the router. Flashed the 52020 version and factory defaulted again. Did the bare minimum config to get it on my network as an AP
- changed IP, gateway and DNS settings
- disabled WAN
- disabled DHCP
- added NTP server
- set SSID to "ddwrt x" for both 2.4 and 5GHz

Result: Devices will connect and operate correctly

Changed SSID to the house-wide SSID (single SSID on both 2.4 and 5GHz) so that this router could become available to any device.

Result: Devices do not want to connect to it. They always prefer devices further away with weaker signal strength.

Used Windows and Android wifi clients for testing

Use different SSIDs for different bands and connect devices accordingly.

I have done that other times for testing and that is not a solution. SSID per band is an ineffective way to run a Wifi network. Running multiple bands on one SSID works perfectly fine on other DDWRT versions eg v44213 and the Wifi clients optimally connect to the best signal. They know the signal strength better than me.

Cool, take it up with Cisco and Broadcom.

It works perfectly fine on this hardware with other versions of DDWRT. I'm not really sure what you are getting at

Most dual band or tri band devices will not choose the faster connection, they will connect to whatever they see first. this will cause performance issues for all connected devices on the network. Legacy 2.4Ghz devices will end up limiting higher performance 5.8Ghz devices capabilities and often lead to chaotic hard to diagnose performance and latency issues. While it appears to be a good idea to let the NIC decide which band to use in practice it is not and usually only ends in tears.
