I have connected my Desktop PC with a Dell Vostro 1015 Laptop with CAT 5E cable. (No Router or hub or any other middle device). My built-in lan of Gigabyte 945GCM-S2C supports 100mb full duplex speed. And the laptop lan supports 1 gigabit speed. As I want to backup large files on the laptop I need at least 8-10 MBps speed on transfer but I am getting only 1.12 MBps speed. I guess this is the problem of the lan, so how can I resolve the issue?
Use a cross-over cable and set both cards to the same speeds manually (which would bee 100 duplex). Make sure you are not running other programs like a virus scan when you are doing the file copy.
I did this but the laptop still shows 10 mbps,, the lan is RTL 8111D I guess...
