How to SpeedTest LAN Traffic on Windows and Linux Clients and Servers

Testing your Local Area Network (LAN) speeds on a regular basis is a good idea to make sure you don’t have any major issues that have crept into the network. I would recommend a couple different free tools to use to accurately test every machine on your network. Below will be a brief explanation of each of the solutions followed with instructions and possible issues you might run into.

Windows clients and servers can be tested using Totusoft’s LAN Speed Test which could also be used to test Window’s clients that have network shares to Linux servers. The application is extremelly simple but will provide a nice basic overview of the speeds your LAN is capable of. The application writes a file to any network share, clears the file cache, and then reads the file back to make sure its not reading the file from cache instead of writing it over the network.

Linksys WRT600N Running DD-WRT Wireless Devices Not Communicating With Wired Devices

If you are having trouble communicating between the wired and wireless networks after installing or upgrading your Linksys WRT600N wireless router with dd-wrt firmware then the issue is likely related to the VLAN configuration. After you flash the firmware on a Linksys WRT600N you will have the default dd-wrt settings. One of these settings includes separating the wired and wireless traffic because this is the correct way to secure things because the wireless network is much more likely to be breached than the wired network. Switching this setting to allow communication between wired and wireless devices is easy by following the directions below.

  1. Login To WRT600N: Visit the web administration GUI at your routers internal IP address using the HTTPS protocol. If HTTPS is not set up then you should first configure that before you proceed.

Linksys WRT 600N Wireless Router Upgraded With DD-WRT Firmware Issues

I have been running dd-wrt firmware on my Linksys wrt600n for awhile now however I have always had some issues. I had finally had the configuration to where the issues were minimal however it has never been perfect. I decided since it had been a couple months it was time to try a newer build from the site. I upgraded and things got a lot worse in terms of wireless on the 2.4 GHz channel so I did a ton of troubleshooting and read a lot of posts semi related to my problems with the 600N on the dd-wrt forum. During the reading I learned a lot about the proper way to flash the firmware and I wanted to share my findings here.

First off when you upgrade the firmware you are supposed to do a hard reset before the firmware upgrade and after the firmware upgrade. A hard reset should be done following the below directions.

**NOTE** Hold the reset button in during this entire process
