Hi Faheem,
MODEM--cable a--port b--SWITCH--port c--cable d --DELL (problem)
+--port e--cable f --MAC (ok)
MODEM--cable a--port g----------------------------DELL (ok)
so from this, I'd say that:
these are ok : cable a,port b,port e,cable f,port g
these are suspect: port c,cable d
so change these with ones from the good list and see if this fixes it.
cheers,
Kev
