I am looking for a USB Extender that will push the signal over ethernet at a distance of 210ft minimum. Everything I seem to find won't operate at that distance. Has anyone seen anything that will push the signal that far? Thanks in advance.
Under ideal conditions, the maximum length of CAT6 Ethernet cable is 300 feet. I'd bet dollars to donuts that you conditions are much less than ideal. If this is the case, then you may have no signal at the end of 210 feet. You should give serious consideration to rethinking your problem and your strategy for solving it.
USB extenders over cat5 cables can easily transmit the signals beyond your desired distance, a good usb extender can make the signal transmission even up to 300ft. with no loss in signal strength. Icron is the finest manufacturer of usb extenders.
