Amazing. I’ve been ‘staring’ at the sys rq key for 20 years with Linux and many years before with Win/Dos, and never really knew how it worked, for what, or if it was still used for anything - even then.
Apparently (from light search) sysreq was mostly used in the old days to halt current job and enter a systems menu.
Anyway, thanks for fixing a long-standing knowledge gap :-)
There’s a cheap zbtlink openwrt wifi6 3000Mbps ‘z8101ax-d’ on AliE for around 50 $. (https://www.aliexpress.com/w/wholesale-zbtlink-openwrt.html?spm=a2g0o.productlist.search.0)
I don’t know how long, and haven’t tried the product, but maybe some here have tried it ?
