Why are LAN speeds so slow?

I have RT-AC66U router (4 Gbps LAN)
Must I simply buy better ethernet cards on both machines?

Even thought the router can transfer 4GBps, that theoretical in a perfect word. You also have to consider the hard drive, the speed of the Ethernet card, and also what type of cable you are using. Not to mention, other network connections going on.

For example, USB 3.0 had 5GBps speeds, right? When I transfer to my HDD, i get maybe 100 megaBTYES per second, but when I use my SSD, I'm getting 500 megaBYTES persecond. I hope that helps.

I feel your pain. But every one seems to forget that the data transfer rate is determined by the pc's hardware, not the network speed. Also cable quality is critical over 100mb. Try to set LAN speed to 100mb and verify network speed. Then work your way up in speed from there.

The law of BOTTLEHECK my friend. Everything on that pipe, from A to B to C to Z must support that speed, any single bad guy on the pipe, and you will be performing at the lowest denominator.

Here's a test. Try to hook up just two computers to your router. Remove the ISP connection and make sure the cables at CAT6. Then try the transfer.

Some cheaper computers these days (mostly laptops) still come with stupid 100 Mbps LAN ports instead of Gigabit. 11-12 MB/s is about what you'd expect out of one of those.

My laptop 7 years ago had Gigabit ethernet...
