Hi All,
I have been using DD-WRT for a while now and been very happy with it.
However, having setup a HTPC (which uses WIFI) and soon to have a nice big file server with all the media on, I am trying to squeeze out some extra speed.
At the moment, if I copy a 4GB file from HTPC to main pc (HTPC on WIFI, PC connected via LAN to Linksys WRT54G (v2) with DD-WRT(v23 sp2)) I manage to use up on average, 40% of the connection. The AP and machine are about 20 feet apart, line of sight. According to vista, I am getting 1.8MB/s throughput.
I have been browsing round all night and tried various tweaks but cannot muster anything more out of it.
The SNR hovers around 55 on channel 13. About the same for most other channels as there is not much in my area. The AP can see 3 other networks, all on 11, but HTPC cannot see any.
My question is, is what I am seeing realistically the max of G? I know you will never get near 100% but what can you get near? Any tips for increasing what I have got?
That's basically what I see. About 6m between the two routers; separated by one non load bearing gyproc wall - approx 45% angle through the wall - Motorola WR850G v2 with latest v24 beta on both ends - one AP, one "repeater bridge."
I get roughly 2.20 mB/sec to 2.30 mB/sec throughput. I am running a Linksys WRT54g with DD-WRT v23 SP2. I'm on the second floor, router's downstairs behind a media panel.
However, once I have traffic going on the other ports on the router (hard wire) it just about dies to about 1.1 mB/sec.
The "raw" speed in G specs are 54mbit/s, but it is half-duplex, so in reality the speed is roughly half of that, add some protocol header and actual data speed is around 20 mbit/s, which translates to some 2,5mbytes/s (20mbit/s : 8bits (=1 byte)) in perfect conditions...

try to test wireless speed connection on my GL, make graph with cacti ..with download via wifi , wireless mode : AP, you can see at the pic that max outbound is 2.45 Mbps

I get up to 3.5mb/s to my AppleTV from my WRT350N. (In N mode)
Is that all the faster N mode is?
I've seen around 2.79 megabytes/sec from a wired computer to wireless laptop in standard G mode and up to 3.23 megabytes/sec with Frame Burst and Afterburner in G mode.
