You can use some of these figures to come up with what Tx power rating would be best for you. As factory lists it a max of 20dBm than a setting of 100mW could be used as 20dBm = 100mW 17dBm = 50mW and so on.
2.4GHz output power per TX chain 802.11b: Max. 20.5dBm @ All rates 802.11g: Max. 20.5dBm @ Low rates Max. 19.5dBm @ High rates Wireless-N 20MHz: Max. 20.5dBm @ Low rates Max. 18.5dBm @ High rates Wireless-N 40MHz: Max. 17.0dBm @ All rates
5GHz output power per TX chain UNII-1 (5150-5250GHz) 802.11a: Max. 14.0dBm @ All rates Wireless-N 20MHz: Max. 11.5dBm @ All rates Wireless-N 40MHz: Max. 12.0dBm @ All rates UNII-3 (5725-5850GHz) 802.11a: Max. 17.5dBm @ High rates 802.11a: Max. 20.0dBm @ Low rates Wireless-N 20MHz: Max. 17.5dBm @ High rates Wireless-N 20MHz: Max. 20.0dBm @ Low rates Wireless-N 40MHz: Max. 17.5dBm @ High rates Wireless-N 40MHz: Max. 21.0dBm @ Low rates
Internel PIFA are rated at 3dBi

The work is definitely in progress as of June 2010 (read thread first): http://www.dd-wrt.com/phpBB2/viewtopic.php?t=73601
- Use only e3000 specific firmware (with e3000) in the name, minimum 14584 Eko build. For example dd-wrt.v24-14584_NEWD-2_K2.6_big-e3000.bin
- Flash straight to the big build using Cisco-Linksys web interface.
- After successful upgrade message comes up, give it extra 2-3 minutes to complete flashing.
- You may need to clear your browser cache after flashing to see dd-wrt's web interface
- Some people have been having heat issues. Raising the router off the ground has helped.
Flashing instructions for the E3000
- Disconnect all cables and wireless clients.
- Do a 30/30/30 reset on router.
- Connect 1 Lan cable to pc doing the flash.
- Log into Web Interface and flash the firmware http://www.dd-wrt.com/dd-wrtv2/downloads/others/eko/V24-K26/svn14853/dd-wrt.v24-14853_NEWD-2_K2.6_std_usb_ftp-e3000.bin
- Wait 5 minutes until WAN light turns on.
- Power cycle by unplugging E3000 for 30 secs.
- Plug E3000 back in and wait about 5 minutes until it finsihes booting.
- Do a 30/30/30 reset on router.
- Wait 3 minutes and log into web interface.
- You may have to clear your browser cache before the web login will display.

As of July 2010 you can only use the trailed builds with the e3000 name in it for initial flashing and nothing else, using other bin's without the e3000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then use the e2k-e3k.bin's for upgrading to newer builds.
DD-WRT E3000 Build information
Always use the E~ series builds for upgrading. Anything else will brick your unit
The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.
ftp://ftp.dd-wrt.com/others/eko/V24-K26/
Brainslayer added E3000 Support from 14929 and on and builds are to be found in the broadcom_K26 folder of his build branch.
ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/
Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.
Some useful tips
- I have noticed with these style of linksys units, cooling can be very important to its performance, thus I have done a nice easy mod that will allow air flow for under the unit. Check this post for details. http://www.dd-wrt.com/phpBB2/viewtopic.php?p=475684&highlight=#475684 -buddee
- At step 5: "Wait 5 minutes until WAN light turns on". I waited for 5 minutes but the WAN light never turned on (I had no ethernet cable connected to the wan port). I didn't bother to wait for the WAN light to come up but I did wait the 5 minutes to continue with step 6 and further.
- The steps above also apply for people running a converted E3000 with a stock linksys firmware. With these steps it is possible to flash your converted E3000 (running stock linksys firmware) with DD-WRT.
