Router does not even show power. "P 075" is getting hot EDIT: Resettable fuse?

Probaply a short circuit somewhere else so the polyfuse gets hot and limits the current

If they follow the Littelfuse nomenclature, this would be
0.75mA
0.75A nominal current.
Check 1812L075. PTC resettable polyfuse.
MAH2104141946: corrected the typo. That's a staple item in my designs.
