I recently bought a Belkin 2m cat5e crossover cable to connect my desktop to my D530 laptop, in the hopes that it would be a faster way for me to directly transfer data between the two. The desktop's ethernet card is a Realtek PCIe FE Family Controller (model no. RTL8167), and the D530's is a Broadcom NetExtreme 57xx Gigabit Controller (model no. B57ND60X). Both seem to be gigabit-capable cards, yet I'm not able to get gigabit speeds from them; when looking at the connection, it shows 100Mbit/s, and the fastest speed that each of them can be set to in Device Manager -> Advanced -> Speed & Duplex is 100Mbit Full Duplex. Even worse, I'm not even getting those speeds when I transfer data - I'm getting a measly 1MB/s, so about 8Mbit/s, and even that is constantly dropping.
So far, I've tried updating uninstalling and then updating both drivers automatically via the Device Manager.
I then manually installed drivers, the Desktop's from here: Realtek RTL81XX PCI-E Network Connection Driver Driver Details | Dell UK, and the laptop's using DriverMax because I couldn't find a driver for it.
Still no luck, and I'm now at a loss for what to try. When I bought the crossover, I really didn't think it'd take this much to get it up and running, I suppose I was under the naive impression it'd be pretty much plug-and-play.
