Hey,
I bought a new Linksys E1200 router because my old router died. I install it exacly as it said in the instructions, when it was completed I had wireless and wired connection but the wired connection was slow. When I did a speedtest it was about 1-2Mbps normally its 10Mbps. I tested it on wireless connection and am getting the 10Mbps.
I connected it directly to the modem and am getting my full connection. I have also tried different Ethernet Cables and its the same thing. I am not using an onboard network card I have a Realtek RTL8139/810x Family Fast Ethernet NIC. I dont think its the NIC since I can get the full connection from the modem alone.
I also have an USB Wireless LAN Card for the same computer and I can get the full connection from that using the router's wifi connection.
So am pretty sure its something to do with the router but am not sure what to do.
Does the router trottle wired connection speeds?
