[QUOTE="Droberts, post: 1841398, member: 13839"] if both pings fail at the same time, this tells us the problem could cable or your pc. (there are many issues that can cause intermittent connectivity issues local to a pc itself.) if both pings fail on more than one pc at the same time, the problem is not your cable, or your pc. It is your router. if both pings fail on one pc, but not on another pc, the problem is not your router. if the ping to the cox next hop ip (defined in your router as the default gateway on your public ip address) fails, but the ping to your pc's default gateway succeeds, the problem is upstream of your router - possibly modem, cable, filter or hardware failure on an upstream network device. if it ends up being the cable you can re-tip them pretty easily. radio shack sells the RJ45 crimp tools & tips. theres a crimping tutorial about halfway through the power point pres labeled "ICND Built around lab similator -1" goes over color codes & tool usage.
