admin/freifunk/assistent/wireless - Failed to execute cbi dispatcher target

[ilippert]

Bug report

What is the problem?
I want to use the assistant to change bandwidth and location of the router.

Instead of being able to do this, I get this error

Failed to execute cbi dispatcher target for entry '/admin/freifunk/assistent/wireless'.
The called action terminated with an exception:
...b/lua/luci/model/cbi/freifunk/assistent/wireless.lua:361: bad argument #2 to 'tonumber' (integer expected, got string)

This occurs on a gl-mt300n-v2 router

What is the expected behaviour?
I should be able to use the assistant to adapt bandwidth.

Firmware Version:
git-19.249.30590-a328a50) / Freifunk Berlin Development abc3c31

Site Configuration:
I have freshly installed firmware. Then restored an old configuration from the same router that has worked successfully for years.

This is a very old Development build (a branch from master from 13 Dec 2019). Can you retest with a recent build? There have been some upstream fixes, which already might fix the problem.
