the firmware selector proposes all versions 21.02 for my linksys WRT1900AC v2, but the 1900AC page still recommends 19.07.7. Can you advise if the 21.02 is fine for my router. system works much better since i installed openwrt i don't want to take risks
The wiki will only be updated (in bulk) after 21.02.0 has been released, that hasn't happened yet (we're at 21.02.0-rc3, in the release candidate phase). In general, the RCs should be fine (and if they aren't tested by users, potential (reported-) issues will never be found nor fixed before final either), but the DSA changes are quite invasive (read about it first).
thank you for the return.
i will try with an RC. where can i read about the DSA changes and is it clear for beginners as i am.
thank you again. "image version mismatch / image check" i understand that i will have to force the image to be installed and reconfigure all settings including ppoe, wireless etc.?
This post is gold for configuring DSA:
I would not have been able to convert my network configuration to DSA without it.
That would be the safest approach.
There is a post in one of the 21.02rc? threads that indicates apparently only the system and network files need to change in /etc/config/. Perhaps through an unrelated error I introduced without realizing it, but I was not able to copy backups of my other files (firewall, wireless, etc.) into /etc/config/ and get everything working. So this is why I suggest safest approach is to just start over from scratch.
Took me longer than I thought. Here's the post about only keeping the new network and system files and using your prior setup files for the rest, but like I said, might be safest to just start from scratch.
Unless there are (non-default) private VLAN configurations currently configured (you'd know, if there are), that thread won't be necessary - the defaults work (LAN side, WAN/ PPPoE needs to be reconfigured by hand, just like anything else) via 192.168.1.1.
Not much risk as you can return to the current version by toggling the power switch.
