What transfer speed should you see on N & G networks ?

I have a WRT610N router which has an inbuilt media server. The cool thing is, you get 2 wireless networks, so you can label one as abg & one as N.

I've been ftp'ing files from the media server, which is a really good way of testing wireless performance. I was just wondering what sort of performance you should see from 54Mbps & N ?

Under FC11 I see anything between 1500KB/sec download & 2400KB/sec download when it's on the N band (5GHZ) but reports 54Mbps connection.

My mac on the other hand pulls around 3000KB/sec transfer on the N band.

I was just wondering what sort of "standard" performance I should expect ? I'm fairly sure that linux latest kernel, the 5GHZ router & Intel Corporation PRO/Wireless 4965 are not connecting N band.

Searches on the news groups shows people asking what G band, N band is, but no ball park, expect these figuers.

Just did some more quick testing.

Router set to N band only (no encryption i.e. TKIP etc)

WinXP (reports 300Mb connection) download @ 3.0MB/sec
Linux (reports 60Mb connection) download @ 3.0MB/sec
Mac (doesn't report anything) downloads @ 3.5MB/sec

Router set to Mixed (ABG/N)

WinXP reports 54Mbps connection downloads @ 2.3MB/sec
Linux reports 54Mbps connection downloads @ 2.4MB/sec
Mac (doesn't report anything) again downloads @ 3.5MB/sec

The WinXP & Linux results come from a dual booting machine and so is on the same hardware.

Whether the lack of security sku's results or not, I don't know, but the Mac did the same transfer speed with or without WPA so I don't think so.

The only slightly annoying thing is that Linux won't connect to the router, when it's set to N-Band only, since the router only offers WPA2 encryption which Linux doesn't seem to like.

Comments ?

These all fall short of network performance expectations IMO. I'm seeing 1.58MB/s in an 802.11g w/ 52% sig strength and a significant number of re-transmits.

What are you ftp'ing to/from ? Is the other end wiresd ? What speen 802 ? Jumbo packets ?
Also you need to use a network test - ftp is not appropriate as it introduces all sorts of file system artifacts.
. Install ttcp

On one end you can ...
ttcp -r -s -f M -p 6666
and on the other
ttcp -t -s -f M -p 6666 othersysname

if you're at all interested in speed, you shouldn't be using wireless.
