Why am I getting such slow transfer rate over wired LAN?

Question

I have a Linksys WRT400N. Im trying to copy 400GB of data over LAN from one PC to another. Im getting 7-8MB/s over wireless AND wired. I have 10/100/1000 network cards in all PCs.

Anything I can do to speed this up?

Solution 1

Linksys WRT400N does NOT have Gigabit LAN support.

That is your bottleneck.

Solution 2

It's because the HDD Speed so you can't do anything.

Solution 3

It really depends on the adapters used within the computers, I work with many different sorts and find anything from 7-12MB/s normal on a 100Mb network. (remember, 8 Megabyes a second is 64 megabits a second)

As others have said, your router is not gigabit compatible, so it will most likely be falling back to a standard 100Mb speed.

If I was you, I would test copying to another machine and then bypassing the current one and copying directly from the other two just to test out your network and see what one has the slower card.

Apart from that, I typically find, if I need to do a really big transfer urgently (>100GB) I usually just rip out the hard drive and put it in a spare dock or internal connection and copy it as it can turn a job from a few hours in to a few minutes.

The computer on which everything is offloaded to has a RAID5 array, which is capable of 100+ MB/s.

Nope, just 3 PCs on wired, and 1 PC on wireless. Network printer as well. Everything is connected directly to the router with CAT5 (or 6, Im not sure) cables.
