oookaaayyyyy

How many MB/s is normal for filetransfer over gibt Ethernet?
I'm somewhere around 23 to 30 over SMB. Is that ok for win7 without raid as fileserver?

I get between 100 and 133 Mbs when transferring video files from my desktop pc to my TV server in the attic over a gigabit network.

@deadmonty
133MBytes/s isn't possible even in theory:
1000 MBit/s / 8 Bits/Byte = 125 MBytes/s. You need to subtract overheads for IP framing, Ethernet framing, SMB packeting etc., so in practice - not more than 100 MBytes/s even wit 9k jumbo frames.

Hey,

this is what I get from Win 7 to Whs 2011 over 2 cheap Switches for one large file and a few small and large files...

 

[Schicksal]

hmm, but how?
if I would get somewhere araoung 60-70 I would be happy.

 

[Luca Brasi]

tricky thing is to find out where the bottleneck is. have you read the first two pages of this thread? good point to start...

Remember there's a difference between peak and sustained transfer...

 

[Luca Brasi]

Sure, this is my last serverbackup with freefilesync:

Please ignore the error
This is a sustained transfer rate of 53 MB/s. Thats ok for me...

Hey Spud !!!

I got me a Cisco SG200-08

Now, I really know my limits with this networking stuff... so it is a bit of advice I'm asking here.

I currently have a wireless ADSL router that uses the default access IP address of 192.168.1.254, and will dynamically assign IP addresses between 192.168.1.1 and 192.168.1.xxx

Most of the stuff in house is using fixed IP addresses; both wireless laptops, wired clients and three wired networked printers.

The Cisco switch also has a default IP address of 192.168.1.254 - the same as the router - I need to change the Cisco address, but what to??

Thanks in advance for any guidance.

If your switch got an own ip adress it has to be managed one. What happens if you type 192.168.1.254 in your browser while you connect one of your laptops via cable to the switch? I assume you will see any kind of admin frontend where you can change its adress.

[Edit] To state the obvious: At the time you do that your router should not be connected to your other devices.
