Hi,
In the past month, I have spoken to two people who had been using very old routers (two diffferent brands) with a Cat 5 cable connecting a PC to the router and a Cat 5 cable connecting the router to a dsl or cable modem. When they tried to switch to a Cat 5e (in one case, he switched to a Cat 6) they could not get a connection. Is it possible that the very old router cannot handle Cat 5e or Cat 6? I thought that the newer cables were backward compatible? Appreciate hearing the experts' opinions. Thanks.
