Not necessarily the network card might be confused and recovers by
being, effectively, disconnected and reconnected. You might find the
same thing if you unplug the cable wait for 10 seconds and plug it

I meant unplug the two cables and plug them back in but the other way
round, so if it is just one connection in the router then the PC
should now work and the other device might be intermittent.

How can you only have one cable if the PC and the smartphone are both
plugged in? Perhaps you mean that the phone is on wifi and only the PC
is plugged in. In which case try the cable in another socket on the
router and if that doesn't help then get hold of another cable, with
luck it is that. If not then it may be difficult to determine whether
it is the router or the PC if you haven't got something else to plug
in to test it.

Yes, very likely.
