What exactly is "Good" wireless throughput?

    I am a little un-clear on this and a night of searching has just made more questions. I have a WRT54G V3 running Firmware Version : v4.20.6 - HyperWRT 2.1b1 (Rupan). I am seeing 5400Kbps +/- average throughput on a 704MB file on G wireless. Is this good, bad, or ugly for wireless G? :cheerup: This is like 5.4 Mbps bieng used out of a (theoretically impossible) 54Mbps. Just seems kinda slow to me. (New to Wireless Networking) Thanks in advance!

    Check http://www.tomsnetworking.com/. They had throughput graphs for several routers/cards. Their numbers are mostly in 2-25 Mbps range, depending on distance.

    I think 54Mbps is shared by send/receive connections so you get 27Mbps in one direction in ideal conditions (no collisions, multipath errors and so on).

    Thank You!

    That's what I needed! Looks like I am doing ok in comparison. I am going to get Qcheck and start tweaking. :thumb:

    Re: Thank You!

    I have a WRT54GS v2.0 sitting in a closet upstairs with a wireless desktop downstairs in the corner of the house (about 40-50 feet from the router) and my laptop at the other corner of the house (again about the same distance from the router).

    I must note that i do have the signal power at 84mW but when I transfer from either my desktop to my laptop or laptop to my desktop, I get 1.8mb/sec = 14.5 Mbps

    I recently bought this router and absolutly LOVE IT! No resets and blazing fast speeds (8 days of uptime so far).

    I've got a similar setup to Flaxx. WRT54G in the corner of the house about 40-50 feet away. wireless strength at 54mW. For some reason I get 4 Mbps (500KB/s) instead of 14.5 though.

    The best I've ever done with my WRT54G v4 is 4 MB/s up and about 3.8 MB/s down. That's nowhere close to what you're getting. :-/

    I assume you mean 4Mbps (Mega bits per second) as opposed to MB/s (Megabytes per second) since 4MB/s is about 36Mbps which is pretty much impossible with 802.11g...

    Nope, I mean megabytes.

    Transferring between my iBook and desktop machine (wireless --> wired), I get about 3950 KB/s, which is just short of a real 4 MB/s (4096 KB/s).

    I can provide screenshots. :p

    Interesting. Everything I've ever read suggests even 30Mbps over 802.11g is impossible... How are you transfering the files? I don't use mac much so I don't know of any tools off the top of my head that you could use to test throughput between your mac and a PC but I'd be more confident of the info if it came from a program like one of the following:

    QCheck
    NetCPS
    Iperf

    Update: Iperf supports Mac!

    It's a straight-up FTP transfer of a 700 MB AVI file. I'm running Serv-U on the Server 2003 box (which is wired over 100 Mbit Ethernet), and using Transmit as the client on OS X.

    I'll play with this Iperf thing when I get home after the weekend. ;-)
