Hi, since your extender does have a Gigabit LAN port, the 100 Mbps link speed you see is not normal. In most cases this happens when the cable doesn’t make full contact (only 2 pairs working instead of 4), or when the PC’s network adapter is forced to 100 Mbps instead of auto. I’d suggest trying another Cat6 cable and making sure your adapter is set to auto negotiation. Once the link comes up at 1 Gbps, the speed should no longer be capped at 100
