Hi there,

I was wondering if anyone might have any suggestions as to which EKO TNG build might be the best for the Linksys WRT54GL v1.0 and v1.1 routers?

I'm currently running "DD-WRT v24-sp2 (01/01/09) std - build 11296M NEWD Eko" on my v1.0 and v1.1, but am finding my WLAN performance between wireless clients cannot exceed 8Mbps performance.

I have tried switching wireless channels, encryption, firewall on/off, nothing seems to help. If I transfer files via wired LAN and wireless clients, performance exceeds 4000KB/s, but drops to 980KB/s on wireless-to-wireless transfers.

My machines include a mix of Wireless-G desktops and laptops. All have an SNR of 35 or higher.

I noticed slightly better performance with the build I'm currently running, but the speed is still WAY too slow VS the stock Linksys firmware.

I have also noticed that no matter how high the SNR is or how close the machines are placed to router, it always seems to show a Wireless speed of 24Mbps, and never goes above that, even though the wireless clients show a speed of 54Mbps. If I force the router to try nothing but 54Mbps under Wireless -> Advanced, none of my client machines can connect to it.

Any help would be greatly appreaciated!

Cheers

whats your range?
whats your tx set at?

8mbps connection or 8mbps throughput?

you got any B devices slowing transfer down?

i doubt that you are going to get more than 3.3
(54mbps / 2 (reality) = 27 / 8 = 3.3 MB/s max)

i dont get much more than 1-2MB/s through-put when transferring files over wireless. (same as you can only get 10MB/s over 100BaseT)

You could try 11650, and see if that improves things, but 11296 (which you have) is the current reliable build for your router.

DD-wrt is not renowned for speed, at least on these wireless G units.

Regarding wireless...try a different wireless channel. See if the 24M connection improves.

Try the 11650 build...and if you like try the 11762 BrainSlayer build... it too was pretty good...don't get into the 1177X+ builds...we are working out some flashing kinks.

Where can I find the TX setting? Maybe I just cannot remember which setting that is atm...

I'm getting 8mbps throughput.

No Wireless-B devices

I actually just switched to channel 1 from 4, and also reduced my transmit power from 200mW down to 21mW, and noticed that now when doing a wireless-to-wireless client file transfer, the router bumps up to 54mbps, but it's still only going at 1200KB/s, better than the previous 900KB/s average I was getting earlier.

wireless
advanced settings
tx or tx power (should default to 70, range 0-251)

Your WRT54GL is not a MIMO router, it can not receive and transmit simultaneously to 2 clients.
It has to buffer what it receives from one of your clients, stop communicating with that client, start communicating with the other client and send the content of the buffer to it.

Quite normal with this kind of router.

Well, you said you have 4000KB/s speed between wired and wireless clients
That is 32MBps and you will not get more out of a 54Mbps connection.
54MBps is peak rate (burst rate) not sustained rate.

You need higher rates, upgrade to 802.11n or use
wired connections. Nothing beats good ol cupper.

200mW ??....you may have a hardware problem. These units need external cooling if taken over 100mW or there abouts.

Thanks for all your feedback folks, gives me a little perspective, and perhaps a solution. If the router is fried cause of the excess transmit power, I have another brand-new WRT54GL never opened that I can use :)

I don't think there is any solution as long as you stick with a WRT54GL, 802.11g, and transfer files via radio between 2 computers.
You will never reach the speed that you expect/wish.

Wifi have, until a few years ago, only been about easy connection and it is more recently that performance has become an issue of interest.

802.11n for example may be sufficient for high def media streaming as long as you only stream 1 video to 1 reception point but it wont cope with multiple streams within your house.

Call me conservative but I use cable wherever I can and use wifi only as access points for the IPhone, wireless cameras, or for visitors with wireless laptops.

same here, surfing is for wifi
anything over 100mb that i need to transfer between machines is either LAN or sneaker net.
