First of all, I'm a total noob at this. I just installed DD-WRT for the first time today, and I've been working all evening to solve the 1-2 Mbps speeds I've been getting. My stock WRT54G2 used to run at 2-3 MB/s when transferring files from my desktop to my laptop.
First, as for speeds, I use the task manager's networking tab to see network utilization. I also use the download window to see speeds. On DD-WRT, I use the status>sys-info tab to see actual connection speed or just look at the task bar icon to see what it's supposed to be running at (it always says 54 Mbps).
My stock unit used to run at about 50% network utilization (NU) when connected at 54 Mbps. After flashing DD-WRT to my router, it dropped to 1-2 Mbps with data transfer rates of around 100-120 Kbps. It made no difference whether my laptop was in the next room, or right next to the router. I tried setting the TX power down to around 35mw, but it made no difference.
I've been seeing lots of stuff on here about channels, tx power reductions, etc. Has anyone tried increasing the TX power? I set mine at 100mw and it solved my problems. It's still not as good as the stock unit was, but my NU is around 29% now with data transfers averaging 15 Mbps. My actual connection rate per sys-info tab is around 36 Mbps.
Like I said, I'm a total noob on this, but why don't you try setting the tx power to around 100 and see what happens.

I figured why not and set my TX power to 100 to see how it does. I have to say it's been 24 hours and I haven't been dropped yet, I'm actually surprised it's worked this well.
I'll edit this post if I come across issues in the near future.
I'm glad it's working for you. I tried all of the lower settings with my laptop right next to the router, and was still getting very low transfer speeds. Setting it to 100 took care of that. I'm wondering, since the settings range from 0 to 251, if something in the later builds re-set the tx power to a lower setting. Does anyone know if it's always been 0-251 or was it, maybe 0-100 before?
It's been a year and half since this thread was started and the only consensus has been to revert to stock or DD-WRT sp1 firmware, or to power cycle the router when the drop occurs.
I've personally fiddled around with wireless advanced settings and flashed to older pre-SP2 builds. But the problem persists.
In terms of TX power, I have it lowered to 48 mW but never tried a higher value. Will give it a go.
Unfortunately I spoke too soon. The router is right back to doing its business and dropping down to 1-2mbps. I ordered a new router the other day, to hell with this one.

Sorry to hear that. I ran mine at 100 mw for about a week and it worked just fine.
I will admit, however, that while setting it up with DD-WRT, I thought I had bricked it, and ordered a timely offered WRT54GS2 from Woot for $17.95. I hooked it up in stock form to see how it would do, and I doubled my network utilization (averaging 50-60% at 54 Mbps) and speeds of 2.75 to just over 3 MB/sec. So far, it hasn't dropped the connection at all, which is why I upgraded the original with DD-WRT. It was losing the connection, requiring a power reboot, about every 3 hours before the upgrade.
I'll be keeping my other one with DD-WRT as a backup.
I have a WRT54GL and I have the same problem, the rate down to 1 or 2 megabytes when I try to connect wi-fi for the laptop or other routers that I have as a client-bridge and others like wds, I tested with and without firewall I have also tested with different ciphers and the open wifi I've also modified the "rate" up and down and still the same problem, I start to lose too many packets icmp and impossible to navigate, this problem does not happen if I connect the cable equipment.
I tested with version 14929: dd-wrt.v24_std_generic.bin, also with dd-wrt.v24-15508_NEWD_std-nokaid.bin and both produce the same problem me and I've only managed to steady improvement mixing versions:
"dd-wrt.v24-15508_NEWD_std-nokaid.bin" in client-bridge and "dd-wrt.v24sp2-(26-10-10)-mini-build-15508-M-NEWD-EKO" in the access point.
Has anyone found a solution?
pd: I have a Comtrend router and not miss a package icmp and has no navigation problems wi-fi.

i had the router with those settings and then i did a full reset and gave it to my mother.
then, after the reset i had the same issue with the rate dropping to 2mbps and occasionally 1mbps, but i remembered what i did the first time.
just try it:
Wireless- Advanced Settins and set Transmission Fixed Rate to 54mbps.
btw, my firmware is:
DD-WRT v24-sp2 (03/27/09) micro-plus

I tried to fix 54mg the rate at "Advanced Settings" but the problem continue.

Are you checking your actual transfer rate or just looking at the connection speed in task manager or hovering over the task bar icon? If you set it at 54 instead of best rate, it will always show 54 (or whatever you set it at). You have to look at the "networking" graph in task manager while transferring a file to see if there was any improvement. Like I said before, try setting the power at 100mw and see what happens.

Hi, I tried to set the powwer at 100mw and others values up and down, down appearence is better (25mw) but is not the solution because quickly they loss packets icmp and rate down too.
power is at 35mw. i'm not just looking at the transfer rate in windows, i'm looking on the router (when it dropped to 2mbps, it was 2mbps displayed), and i'm testing it. i usually did heavy browsing and torrents so if it were somehing wrong i would have noticed it. i used to download with 2.3MB/s maximum.
