BUG-reporter:

Supply the following if possible:

  • Device problem occurs on TP-Link TL-WR1043ND v1

  • Software versions of OpenWrt/LEDE release, packages, etc. OpenWrt 21.02.0-rc1 r16046-59980f7aaf / LuCI openwrt-21.02 branch git-21.106.55967-06dd6b5

  • Steps to reproduce

Upgrade go OpenWrt 21.02.1-rc1 without saving previous configs (otherwise system will become unstable immediately after upgrade). Turn on Wireless in Network-->Wireless-->.... After this a device becomes unstable and completely unusable starting to reboot again and again.

George-TL:

Are you trying to run OpenWRT 21.02 on device with 32 MB of RAM?
Please provide "free" command output before and after wifi activation.

BUG-reporter:

Hello. Yes, I am trying to run OpenWRT 21.02 on device with 32 MB of RAM. And here is "free" command output after wifi activation:

Now I am not able to turn off wifi because it is rebooting once I am trying to load luci in browser (and I don't know how to disable it in configs). And yes, it is because it seems oom-killer kills something:

Also if 21.02 is not for this device, why there are package builds for it?

George-TL:

Out of memory: Killed process

  1. ask someone skilled to replace RAM with 64MB module - device will behave 'less worse'

  2. remove luci and hope for the best

  3. time to replace device with something different/better

https://openwrt.org/tag/32ram

https://openwrt.org/tag/64ram

Also if 21.02 is not for this device, why there are package builds for it?

Because:

  • SoC is still supported

  • image fits into Flash

Image fits but router works unstable. So what's the point?
