First perform these steps on each device to get the hardware up on the current DD-WRT firmware with desired features... 1. perform a [[http://www.dd-wrt.com/wiki/index.php/Hard_reset_or_30/30/30|30/30/30 hard reset]] to make sure it's at factory defaults (note this is using the recessed red ''reset'' button, not the protruding blue one for WDS) 1. set your machine's wired network interface to a static address of 192.168.1.2/255.255.255.252 1. connect to the [[http://192.168.1.1/|management WebUI]] through any LAN port (initial login is a username of ''root'' with the password ''admin'') 1. upgrade the flash with a trailed E4200 mini build like [[http://dd-wrt.com/dd-wrtv2/downloads/others/eko/BrainSlayer-V24-preSP2/2012/03-19-12-r18777/broadcom_K26/dd-wrt.v24-18777_NEWD-2_K2.6_mini-e4200.bin|dd-wrt.v24-18777_NEWD-2_K2.6_mini-e4200.bin]] (the Cisco/Linksys firmware updater looks for special headers, so this is the first in a two-stage load) 1. wait five minutes to make sure everything's booted and written to NVRAM (now is a good time to grab a beer) 1. perform another [[http://www.dd-wrt.com/wiki/index.php/Hard_reset_or_30/30/30|30/30/30]] to make sure any configuration artifacts are reset to the defaults for this build 1. confirm the [[http://192.168.1.1/|DD-WRT password reset page]] is displayed 1. set root/admin as the new login (yes, I know that's the same as the old login) 1. [[http://192.168.1.1/backup/cfe.bin|backup the CFE]] as ''routername_cfe.bin'' (it embeds the original interface MAC so you want one archived for each device) and stash it somewhere for long term safekeeping, see [[http://www.dd-wrt.com/wiki/index.php/CFE_backup|here]] for details) 1. upgrade flash with a more featureful NV60K build like [[http://dd-wrt.com/dd-wrtv2/downloads/others/eko/BrainSlayer-V24-preSP2/2013/01-01-2013-r20453/broadcom_K26/dd-wrt.v24-20453_NEWD-2_K2.6_std_usb_nas-nv60k.bin|dd-wrt.v24-20453_NEWD-2_K2.6_std_usb_nas-nv60k.bin]] (this adds IPv6 and SNMP support, which we'll want) 1. wait an additional five minutes (and grab another beer if you like) 1. perform yet another [[http://www.dd-wrt.com/wiki/index.php/Hard_reset_or_30/30/30|30/30/30]] 1. wait five more minutes (another beer... why not?) 1. confirm [[http://192.168.1.1/|password reset page]] is displayed and ''Firmware: DD-WRT v24-sp2 (12/31/12) std-usb-nas'' shows in the top-right corner 1. set root/admin as the new login (we'll change it to something safe last thing) 1. celebrate with beer = Initial Configuration = After sobering up, set these basic configuration options which deviate from the factory default configuration settings, as organized in the DD-WRT !WebUI!... * '''Setup''' * '''Basic Setup''' * '''WAN Setup''' * '''WAN Connection Type''' * '''Connection Type:''' Disabled * '''Optional Settings''' * '''Router Name:''' ''(enter the short hostname)'' * '''Hostname:''' ''(reenter the short hostname)'' * '''Domain Name:''' ''yuggoth.org'' * '''STP:''' Enable * '''Network Setup''' * '''WAN Port''' * '''Assign WAN Port to Switch:''' Yes |
Highlights
Some random notes on the core switch build and configuration...
- two for redundant operation
- a third as a cold spare
- higher-capacity power supplies
- heatsinks and thermal adhesive for switch chips
with modern Iceweasel/Firefox use Web Developer -> Get More Tools and install the Web Developer Extension, then after restarting use Web Developer Extension -> Miscellaneous -> Clear Private Data -> Clear HTTP Authentication to clear HTTP Basic Auth credentials after changing DD-WRT management passwords (otherwise any attempts to Save/Apply changes just go to a failure error or blank page)
Firmware Installation
First perform these steps on each device to get the hardware up on the current DD-WRT firmware with desired features...
perform a 30/30/30 hard reset to make sure it's at factory defaults (note this is using the recessed red reset button, not the protruding blue one for WDS)
- set your machine's wired network interface to a static address of 192.168.1.2/255.255.255.252
connect to the management WebUI through any LAN port (initial login is a username of root with the password admin)
upgrade the flash with a trailed E4200 mini build like dd-wrt.v24-18777_NEWD-2_K2.6_mini-e4200.bin (the Cisco/Linksys firmware updater looks for special headers, so this is the first in a two-stage load)
- wait five minutes to make sure everything's booted and written to NVRAM (now is a good time to grab a beer)
perform another 30/30/30 to make sure any configuration artifacts are reset to the defaults for this build
confirm the DD-WRT password reset page is displayed
- set root/admin as the new login (yes, I know that's the same as the old login)
backup the CFE as routername_cfe.bin (it embeds the original interface MAC so you want one archived for each device) and stash it somewhere for long term safekeeping, see here for details)
upgrade flash with a more featureful NV60K build like dd-wrt.v24-20453_NEWD-2_K2.6_std_usb_nas-nv60k.bin (this adds IPv6 and SNMP support, which we'll want)
- wait an additional five minutes (and grab another beer if you like)
perform yet another 30/30/30
- wait five more minutes (another beer... why not?)
confirm password reset page is displayed and Firmware: DD-WRT v24-sp2 (12/31/12) std-usb-nas shows in the top-right corner
- set root/admin as the new login (we'll change it to something safe last thing)
- celebrate with beer
