Using a cat6 cable from my router to run up to the attic and down into a bedroom (total distance maybe 20Meters) using a cable that has been in situ for a couple of years and I get the following scenarios:
- plugged directly into a pc ethernet - no cable detected
- plugged into a netgear 108 unmanaged switch - no lights and no internet on pc connected to switch
- plug into a cheap cable extender and then antother cable is plugged directly into the pc ethernet. - works
I'm trying to use this for a home office but it won't work through the switch what is the problem?
