Wireless bridge mode on Netgear WNR2000 V2

Flashing netgear router WNR2000v2

1. do a hard reset with rest to factory defaults (“30/30/30” reset) on WNR2000v2 router (“router”). Check to see if defaults kicked in
2. Download “trailer” build for router. This is a version of DD-WRT specifically addressed to the router and will have the router name in it.
3. Disable compound TCP for windows Vista or newer
CTCP can be enabled with the command:
netsh interface tcp set global congestionprovider=ctcp
or disabled with the command:
netsh interface tcp set global congestionprovider=none
To display the current setting for CTCP use:
netsh interface tcp show global

E.g. (in admin cmd window):
C:\Windows\system32>netsh interface tcp show global

30/30/30 reset: with the router on, press and hold reset switch for 30 seconds. DO NOT let go. Turn off the router power using the OFF switch, continue to press the reset switch for another 30 seconds. DO NOT LET GO. With the reset switch continually pressed, turn on the router power. Continue to keep the reset switch pressed for another 30 seconds. Wait about 2 minutes and log in to the router to check if reset took effect. You should be able to log in with the defaults.

Router default login: Netgear was thoughtful with the WNR2000v2: it provided an on-off switch at the back of the router. Also, they printed the default access credentials right on the back of the router:
http://www.routerlogin.net
login: admin
pass: password
