Hello, I own an Acer Aspire 5 A515-51G-896B and the LAN cable transfer speed is capped at 100 Mbps.-The router supports gigabit network (other devices work properly)
-I use CAT 5e cable (I tried many of them, I also tested it with a cable tester, it is wired according to T568B standard)
-I installed the Realtek PCIe GBE Family Controller drivers from the official Acer website
-I tried Full duplex 1.0 Gbps (automatically as well)
-I disabled green ethernet
-I disabled Auto disable gigabit network
-I disabled the Ethernet Saver network
Nothing works and I still only have 100 Mbps speed. Please help thank you.
