After using this product for a month I was ready to write a bad review and bash it to pieces. The occasional engrish, and very inconsistent performance was frustrating, but then again I really wasn’t using the product as it was intended to be used. My wireless router does not have an internet connection, so I was using a DWL G820 to bridge my SMC router to another wireless router that did have an outside connection. The DWL G820 worked great when I had it connecting to a single computer, but when connected to my router it barely worked for a few days, and then quit working completely.

Since the device worked fine when connected to a single computer I decided to give configuration a second chance before hitting it with a hammer. Here are the steps I followed to use this device as a wireless bridge between two routers:

• Connect the DWL G820 to a computer via crossover cable.
• Manually set the IP of the computer to 192.168.0.XXX and browse to 192.168.0.35 to manage the device.
• Configure the DWL G820 to connect to the appropriate wireless network, and change the default password.
• Set the computer to DHCP so that it may automatically retrieve an IP address from the router that you connected to with the bridge.
• Test the connection by browsing to a website to make sure that the bridge is working.
• Now plug the DWL G820 into the WAN port of the router, and open up advanced configuration for the router.
• DHCP was not working when I plugged my DWL G820 into the router, so configure the router to use a static IP that is in the range of the wireless router that you are connecting to. On mine the settings were: IP-192.168.1.XXX, Gateway-192.168.1.1.

Before following the above steps I tried using a regular ethernet cable, and about every possible configuration setting on the router with very poor/inconsistent results. I now have 1 week of flawless performance, which is looking much better than the few hours of usable connection I had before. Most of the complaints I read about the bridge can be blamed on user error, although I do think they could have made it easier to configure without having to jump through a hoop. Some people have reported it overheats easily, but so far I have had no trouble with that. For $29 after rebate this bridge has served as a good cheap component to handle my needs, and should work great for anyone looking to use it how it was originally intended.

*Note: The batch scripts below were created for Windows XP.
Many people will usually end up using one computer to handle most everything, so you can imagine how much software gets installed and how sluggish it can get. With everything that starts automatically my laptop easily pushes 800MB of RAM usage after startup.

Many processes that are enabled by default are not used all the time; in fact I rarely use many of the ones on my laptop. One way to trim down the load on a computer without having to completely remove software is to setup scripts to manually start/stop processes as needed.

Step 1: Identify categories to group rarely used processes under
Categories for my computer:

• IIS, ASP.NET development
• PHP, apache development
• Cold fusion development
• Proxy services (Tor/Privoxy)

Step 2: Find executables and processes that are started automatically for each category
This step is a bit of trial and error; focus on a few at a time because finding dependencies for a large number of processes would not be fun.
-Set each relevant service to “Manual” startup.
-Remove each relevant executable from automatically starting up.

Step 3: Create a batch script for each category
Place commands to start/stop each process and executable from step 2 into a batch file.
The following are provided as an example, they may need modification for other installs.

IIS.bat:

@echo off
set x="%1"
set y="%2"
IF %x%=="start" (
net start "SQL Server (SQLEXPRESS)"
net start "SQL Server Browser"
net start "SQL Server FullText Search (SQLEXPRESS)"
net start "SQL Server VSS Writer"
net start "Simple Mail Transfer Protocol (SMTP)"
net start "World Wide Web Publishing"
net start "IIS Admin"
net start ".NET Runtime Optimization Service v2.0.50727_X86"
) ELSE IF %x%=="stop" (
net stop "SQL Server (SQLEXPRESS)"
net stop "SQL Server Browser"
net stop "SQL Server FullText Search (SQLEXPRESS)"
net stop "SQL Server VSS Writer"
net stop "Simple Mail Transfer Protocol (SMTP)"
net stop "World Wide Web Publishing"
net stop "IIS Admin"
net stop ".NET Runtime Optimization Service v2.0.50727_X86"
) ELSE (
echo Valid Options:
echo start
echo stop
);
IF %y%=="nopause" (
echo Done with apache.bat
) ELSE (
pause
)

@echo off
set x="%1"
set y="%2"
IF %x%=="start" (
start "httpd" httpd.exe
start "ApacheMonitor" /Dc:\"Program Files"\"Apache Software Foundation"\Apache2.2\bin /B ApacheMonitor.exe
net start "mysql"
) ELSE IF %x%=="stop" (
tskill ApacheMonitor
tskill httpd
net stop "mysql"
) ELSE (
echo Valid Options:
echo start
echo stop
);
IF %y%=="nopause" (
echo Done with apache.bat
) ELSE (
pause
)

@echo off
set x="%1"
set y="%2"
IF %x%=="start" (
net start "ColdFusion 8 .NET Service"
net start "ColdFusion 8 Application Server"
net start "ColdFusion 8 ODBC Agent"
net start "ColdFusion 8 ODBC Server"
) ELSE IF %x%=="stop" (
net stop "ColdFusion 8 .NET Service"
net stop "ColdFusion 8 Application Server"
net stop "ColdFusion 8 ODBC Agent"
net stop "ColdFusion 8 ODBC Server"
) ELSE (
echo Valid Options:
echo start
echo stop
);
IF %y%=="nopause" (
echo Done with coldfusion
) ELSE (
pause
)

@echo off
set x="%1"
set y="%2"
IF %x%=="start" (
start "vidalia" /Dc:\"Program Files"\vidalia /B vidalia.exe
start "privoxy" /Dc:\"Program Files"\privoxy /B privoxy.exe
start "pg2" /Dc:\"Program Files"\PeerGuardian2 /B pg2.exe
) ELSE IF %x%=="stop" (
tskill privoxy
tskill vidalia
tskill tor
tskill pg2
) ELSE (
echo Valid Options:
echo start
echo stop
);
IF %y%=="nopause" (
echo Done with apache.bat
) ELSE (
pause
)

Step 4: Create scripts to start and stop all at once
Add a reference to each of the above batch files into a master batch that can be used for starting/stopping all at once.
startall.bat:

@echo off
start /B apache start nopause
start /B tor start nopause
start /B iis start nopause
start /B cf start nopause
pause

@echo off
start /B apache stop nopause
start /B tor stop nopause
start /B iis stop nopause
start /B cf stop nopause
pause

Place these batch files into a folder that is within your PATH so they can be executed using Start->Run. I prefer keeping these and other random command tools in a central location that has been added to my PATH variable.
C:\cmdtools

Start->Run commands to START services:

iis start
apache start
cf start
tor start
startall

iis stop
apache stop
cf stop
tor stop
killall
