I have three Alienware laptops. All the three have Windows 10 installed and all three have Killer Gigabit Ethernet Card. I also have a CAT6 cable.

The problem is that when transfering files from first to second laptop the speed is 100 Mbps. But when transferring from first to third laptop or vice versa the speed is only 11 Mbps.

I have tried tweaking the Advanced Settings of the Network Adaptor but to no use. Can Homegroup be the problem? Any help will be appreciated.

Thanks. Eliminates the cable and a host of other possibilities.

I would not expect Homegroup to be involved. Homegroup's purpose is on the sharing going on and not the speed of that sharing per se.

Try B to C. I figure that connection will be slow also. Thus implicating C as the culprit....

Check that the network adapter card on C is set for GB speeds. Not a lower value or "auto" / "auto negotiate".

If speed/duplex is okay then grind through the rest of the settings comparing the cards on A, B, and C.

Make sure all three have identical drivers. If there are differences then maybe upgrade C to be the same as A or B.

First to third (second?) is 100Mbps, then you say first to third again at 11Mbps....

Are you going through a hub or a router? Or laptop to laptop, then moving the cable?

Make and model(s)?

If a hub or router first thing I would do is take the Cat 6 cable going to laptop #2 and move it to serve laptop #3. See if the speed to laptop 3 improves.

Objective being to narrow down the problem, by elimination, to a specific port or cable.

Let me clarify the situation:
There are three Alienware latops A, B & C. All three of them have Windows 10 and same Killer e2400 Gigabit network adaptor.
I use a single CAT6 ethernet cable to transfer files.
The problem is that the transfer from A to B or vice-versa gives 100 MBps speed but transfer from A to C or vice-versa gives only 11 MBps.
I do not use any Router or Hub and connect the laptops directly.
