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 then 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 Internal PIFA antennas are rated at 3dBi
IMPORTANT: 5Ghz is not supported by DD-WRT, (May 16, 2013)
Flashing instructions for the E3200
- INITIAL FLASH MUST BE WITH THE TRAILED BUILD (with the router name)
- If already running DD-WRT only use the NV60K build (or the trailed build)
- Also reference this post regarding the newer NV60K.bin files for some Linksys E-series routers
- Do not confuse this with other E-series routers that must use only the NV64K builds
- Support for this unit was added in build 17041, so do not use an older build or you will brick your unit!
- READ the Peacock Announcement Carefully!
- Disconnect all cables and wireless clients.
- Perform a 30/30/30 reset to the E3200.
- Connect 1 LAN cable to the computer that is performing the flash.
- Log into Web Interface and flash the firmware E3200 Trailed Initial Flash Build.
- Wait 10 minutes until the WLAN (wireless) light turns on.
- Power cycle the E3200 by unplugging it for 10 seconds.
- Plug the E3200 back in and wait about 5 minutes until it finishes booting.
- Perform a 30/30/30 reset to the E3200.
- Wait 3 minutes then log into web interface.
- To flash other builds when running DD-WRT, only use the nv60k (or trailed) builds. The appropriate files will end with nv60k.bin and as noted above, only use nv60k builds 17041 or greater.
- K3X builds exist for the E3200: research the device and new build threads for reports
For build locations see Where do I download firmware?
Reverting to stock firmware
Download the stock firmware image from the manufacturer support website, reset the router back to defaults using a 30-30-30 hard reset, then flash the stock image from the DD-WRT GUI. Wait at least 5 minutes for it to finish, reset again, then access the Linksys GUI @192.168.1.1.
