Sorry for my English.
I have a Netgear R6220 router with OpenWrt 19.07.5. I want to update it to version 22.03. When i try to flash the file (openwrt-22.03.0-ramips-mt7621-netgear_r6220-squashfs-sysupgrade.bin) i get a error who says :
Device r6220 not supported by this image Supported devices: netgear,r6220 r6220 - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA Image check failed.
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
Select 'Force upgrade' to flash the image even if the image format check fails. Use only if you are sure that the firmware is correct and meant for your device!
I continue? The problem is only "swconfig to DSA"?
I Select: “Force upgrade”?
Is there a substantial performance degradation with this firmware?
