Network cables are common, guarantee a specific speed that wifi cannot on daily usage and i take cat5 cables for granted. Until this moment i never have had a dud cable until this seemingly old cable decided not to work any more.
It looks perfect and i would love my several hours back i spent trying to figure why at that moment after years of being not interfered with when it just then packed up after spending a fun couple of hours troubleshooting the card a r8169** Gigabit Ethernet* and the router both being blameless.
* The binary blob driver that is supplied might be damaging the cable ? ** a bit shit until recently with reboots my purchase mistake [edimax].
