Hello everyone,

Quick simple question so I stop hitting myself against the wall:

My problem:

- Have a laptop with 250 GB of data that I want to move to my new Desktop PC

- WiFi transfer speed is extremely bad (1.4 MB/sec at most).. I will grow gray hair for then those 250 GB's are done. Cards are 54 Mbps (at least 6-7 MB/sec) but not getting there and have tried so many things already... so frustrating..

- So I decided to try to connect the TWO computers directly but I am unable to get a direct connection via Ethernet because (here is the question for you guys), I think you cannot connect TWO computers direct LAN to LAN port with a regular Cat5e Ethernet cable???

Is this correct? I am not using any hub, or router, etc. Just plain 1 on 1 connection.

When I plug the standard Ethernet cat5e wire, in BOTH computers I can see there is a new Ethernet connection but is marked as "Unidentified network - Public Network" and I can click on the "Local Area Connection" link where it shows it's status but on the bottom right of the screen shows a computer screen with a "yellow triangle" and it reads "limited". (so I need to use an external router?)

Can this status be changed with a 1 on 1 connection with the regular cat5e or once I get the Crossover this network won't be limited anymore?

The old computer is a laptop with Windows 7 Home Premium and the new computer is a Windows 8.1 (both are 64 bits).

Do I need instead a CROSSOVER wire? After days I found somewhere that only the Crossover wire is the one that would allow me to connect 1 on 1 the two computers?

If so, well I will need to get one (hard where I live) so the final question would be:

- Can I use one of my un-used routers (a NETGEAR model WNDR3800) to put in between the two computers and connect to this router each computer (each computer with it's own Ethernet cat5e wire) and be able to exploit the 1 Gbps speed both computers can offer with NIC card I have on them?

Any help, would be greatly appreciated you have no idea.. or if I could work this out you guy until we figure out the problem would really be awesome..

Thanks! :(

Crossover cables are largely not needed on modern PCs. A standard cable should work since all NICs have auto MDI-X and will automatically configure themselves when connected to another client.

To make things easier, you can use your old gigabit router and IPs will be assigned automatically. You should be able to transfer at gigabit speeds.

If you just want to use the PC-to-PC connection, you'll need to remember to manually set an IP address on both computers. Just set them for 10.0.0.1 and 10.0.0.2 with a netmask of 255.255.255.0. The default gateway address is not needed.

Hi I actually know for a fact that I have the regular Cat5e wire and not a Crossover wire... found a guide yesterday where you just have to see the colors the wire has, etc., so mine is not a Crossover one, but thanks.. the provided guide is good too..

Mmm it looks like I do..

But well, I don't have one and don't think I can get one near my area, so using the Netgear router posted before, would solve this file transfer issue? Sorry for this noob questions, I'm not really network saavy :(

Hi,

Well you helped me confirm that I could actually use the Netgear router I had (1 Gbps speed) so thanks for that!

This was one of my last ideas on how to resolve the super slow speed issues but was not sure it would work but you helped me out to try it out.

So after I just put the Netgear router and then from my laptop plugged the ethernet wire to the Netgear and then doing the same with the Desktop, I just had to select to connect to the new default Network from the router.

The wireless/internet disconnected (which I don't care cause I needed to transfer files NOT over the Internet or wirelessly as it is slower) and after 5 days, I finally was able to get not speeds of 1.2 MB/sec but up to 60 MB/sec !!! what a difference. I already backed up the 250 GB data I had on my laptop... Amazing...

BUT........................

This speed of 60 MB/sec is just like 50-60% of the data transfer capacity. Close to 100% would be to have around 90-100 Megabytes / sec. Is there any way to improve even more the data transfer rate via Ethernet with a router?

- Ethernet router can handle 1 Gbps
- Both LAN cards (laptop and desktop) can handle 1 Gbps too

Any suggestons? tricks? etc.?

If not, well, not a problem. Main problem I had was solved. I am just glad I kept that Netgear router!! otherwise I would still be having headaches!

Thanks again!!

Some people have identified the flow control function on NICs to cause problem in a mixed 1Gbs/100MBs environment. This doesn't seem to apply to your setup, but it might be worth a try to disable the flow control mechanism. http://www.smallnetbuilder.com/index2.php?option=com_content&task=view&id=30212&pop=1&page=0&Itemid=49

Also, you can try the direct PC-to-PC wired connection as mentioned previously, although it will take a little more work versus using the router.

Thanks for the mixed gigabit-megabit article but in my case I only had two ethernet connections and no third computer at all. Does this still matter?

On the PC 2 PC, well I originally had it configured with the IP addresses, etc., but the Ethernet was being ignored and all was running through WiFi. Even if I deactivated WiFi, bothe computers wouldn't recognize the Network they were on ("unidentified network, no internet access" text) so I couldn't do anything anyways, until I used the Netgear router as an Intermediary.

So I don't think the PC 2 PC will work for me... too bad you can sit on my side to see and solve my problem lol !!

Thanks at least I managed to transfer everything I wanted already with the router solution in between...
