Why my home Wired LAN only running at 11 mb/sec with file transfer?

chong67 12,757 595 September 6, 2010 at 11:14 AM
I got a Wireless G router.

Ethernet is suppose to rate up to 100mb/s right? I have a gigabyte port on my desktop only but not others.

OK, so I am WIRED now and I transfer a big file between two computers and Windows say it is transfering at 11 mb/sec. That is slow!

Is there a way to increase this speed?

Does Windows say MB/s or Mb/s?

Yes both are WIRED.

Window is saying 11.1 MB/second. That is the max and constant speed.

11.1MB/s = 88.8Mb/s. Your LAN is running fine.

Oh! It does seem slow!

Perhaps I need a gigabyte port router that support Tomato.

100 MB/s is different than 100 mb/s

10 MB/s ~ 100 mb/s

Yep. 11MByte/s is excellent/expected for a 100Mbit network.

You could opt for a Gigabit switch alone, if you don't need a new router. Although, obviously this will mean only computers connected to the Gb switch can communicate at Gb speeds. Stuff connected to the 100Mbps router will remain at 100Mbps.

Haha okay you got me. 10MBps ~ 100Mbps of course ignoring the factoring in the 8 bits in one byte.

It seem like if I transfer thru a USB docking station, its faster than this.

USB=480mb/s
LAN=100mb/s

remember that file transfers are limited in speed to the slowest applicable part of the network: adapter on either end and any switches/hubs/etc in between -- as well as any interference in the networking and overall pc performance (older systems cannot keep up with even 10/100 speeds, and gigabit adapters can tax a slower system's cpu)

start a lengthy file transfer between those computers, then look at the network utilization graph in task manager on each one.... a 10/100 port should be at 70%+, a gigabit port running 100mbit/sec, 7-10%... provided that both ends are wired connections (wireless will normally be slower than 10/100 speeds).

Also, don't forget that even with a gigabit switch you are still limited to the speeds of the hard drives themselves. The switch might be 10 times faster than the one you are using, but the speed increase might only be 3 or 4 times as fast.
