since i switched to OpenWrt on my linksys router i added some packagesa and upgrades were performed as described here: https://forum.openwrt.org/t/how-to-keep-packages-settings-after-upgrading/38998
Now change to DSA is coming up and keeping settings is not recommended.
I have some questions in advance before facing bigger problems and ending up in annoying reconfiguration.
Can i still use the above-mentioned instruction or do i run into the same problems as with keeping settings in the "normal" upgrade option?
what is lost by upgrading without keeping settings?
a) Changing IP from default to 192.168.0.1
b) Static leases
c) USB support
d) mount points
f) Configuration of Dynamic DNS
g) Configuration of wireguard: keys, etc
Can you recommend a way to avoid re-configuring? Even better, is there a step by step instruction you could share.
Thanks in advance
WRT1900ACS --> mvebu, which in turn means the swconfig --> DSA migration happens between 19.07.x and 21.02.x for this device.
Follow the advice and reconfigure from scratch (only using your old configuration as loose reference), the networking syntax and semantics will be completely different, keeping settings (or restoring old backups) would result in a guaranteed (soft-)brick.
You need to start the config from scratch.
For the packages you need, and default ip adress, you may build your own image with
This looks scary, but you'll get it done, it's easy to rebuild your own image for each upgrade without to have to reinstall the specific packages. Config can also be preserved, excepted for this transition from 19 to 21.x version.
example of build parameters
make image PROFILE=linksys_wrt1900acs PACKAGES="luci-ssl wifischedule luci-app-wifischedule luci-app-advanced-reboot luci-app-wireguard nano luci-app-sqm block-mount e2fsprogs kmod-usb-core kmod-usb-storage-uas kmod-fs-ext4 kmod-fs-exfat kmod-fs-vfat kmod-usb-storage kmod-usb2 kmod-usb3 hdparm luci-app-hd-idle -ppp --ppp-mod-pppoe" EXTRA_IMAGE_NAME="myownbuild" FILES="files/"
In the image builder folder, you'll have to create the following file to change the default network
uci -q batch << EOI
Thanks for your reply. Unfortunately it seems to be some amount of work and at least some risk for transient loss of function... I will order a second (backup) router, to avoid trouble with my family ;-).
Regarding image builder. When i have Managed to setting Up the first router with 21.02. my intention is to Clone everything and Set Up the second (Back Up) Router exactly the Same way. Is There an Option to "Clone" everything (package config etc) build an Image and transfere it to the second Router. Aim is to have two identical router for Back Up purpose.
21.02.1 stable now for this router? any known issues with wireguard?
Hope i find some time to do the Upgrade this weekend. I will Share my experience asap. Best Stephan
Nope, wireguard works flawlessly here 24/7 ...
After the config from scratch, which took a while here (because of banip, wireguard, firewall rules, stubby, static dhcp leases), 21.02.1 runs very stable ...
Did spend/waste some time yesterday evening, now wireguard and ddns run without errors. Did Have some trouble with USB support which ist not solved yet.
cheers did the upgrade from 19.07.2 to 21.02.1 configured everything and all is running smoothly
what kind of usb problems? i have a 16gb usb stick attached with no problems at all ...
I lost the access to Services in LuCI web interface. However using a different howto with less USB packages now everything works
