I am using 3 wireless routers to extend coverage around my property. When I connect then them with short ethernet cables, it works as expected. However, in actual operation the last router is connected LAN > LAN via a 145 foot CAT 6 cable. I used a Ethernet cable checker and the cable and connectors are working. However, on the last router the Ethernet port light does not come on. Are the Buffalo ethernet circuits not able to transmit this far?
Topology: LinkSys with Internet access, LAN port connected to WZR-HP-G300NH LAN
