TM Riger DB120-WL reflash with TD-W8951ND Stock Firmware

If you are unhappy of your Riger DB120-WL Streamyx residential modem wireless router because of its buggy stock firmware given by TM for you as FREE, now you are not anymore locked by your ISP you will now have the chance to re-flashing your device with the TP-Link TD-W8951ND v5 third party stock firmware that will give you the total freedom.

Before you proceed, take this precaution.

• This applicable only Riger DB120-WL (Silver) with Firmware Riger v4 installed by default.
• Before you proceed updating, please connect your PC directly via LAN cable to DB120-WL
• This may void your warranty (may or may not be, since you didn't open the case)
• Doing this is at your own risk!

Step 1. Download Firmware

• Download TP-LINK TD-W8951ND v5 firmware from TP-Link Websites

Step 2. Extract

• Open zip file and then open "TD-W8951ND_V5_140226 & TD-W8951ND_V5_140306" folder, extract "TD-W8951_V5_140306" folder (simply click once and drag)

Step 3. Login

• Note: Do this only when computer connected via LAN Cable (Hardwired)
• Username: tmadmin
• Password: Adm@**** (**** is the last 4 HEX digit of MAC Address, eg: D1E3 => Adm@D1E3, you can find bottom of your DB120-WL)

Step 4. Click maintenance

• After successful login, click maintenance and then click Firmware, until you see this page:

Step 5. Choose firmware

• Click New Firmware Location: "Browse" button and then locate back where you extract just now, and then open that folder and choose "ras" file.

Step 6. Proceed!

• Click "UPGRADE" button! and wait until you see a progress bar!

Step 7. Update complete

• Once progress bar reach 100% and it will redirect to new TP-Link login page!
• Please login using previous username and password (it's look awkward when login using tmadmin under TP-Link page, lol)

Step 8. Finished!

• Well done, now you have working DB120-WL with TP-Link Firmware! TP-Link will use your previous configuration.

Step 9. Improve Wireless Security

• Click Interface Setup tab and then click Wireless
• Scroll down until you find Multiple SSID Settings, change SSID Index to 2.
• Change SSID: Riger1 to any string you like,
• Then change encryption to WPA2-PSK and put any password you like.
• Repeat until SSID Index: 4
• This simply blocking from someone using your hidden wireless, because default DB120-WL allow other to join your wireless freely by simply enter "Riger1" or "Riger2" or "Riger3" SSID.

Jetway J7F2 Four LAN Mini-ITX for pfSense

For quite a while I was running m0n0wall on an old dell laptop with two NICs. This worked out pretty well because the laptop had a built-in screen, keyboard, and battery backup of sorts. It was also fairly portable. At some point I decided I wanted to do a bit more with my firewall and move to more powerful hardware. In particular, I wanted to try out pfSense, a m0n0wall fork. pfSense contains a package management system that allows you to install a wide variety of services including: Snort, Squid, FreeSWITCH, OpenBGPD, to name a few. I'll return to these in subsequent posts. I also needed more interfaces to be able to properly segregate my wireless network from my wired network.

I've been a big fan of the smaller form factor x86 machines for a while. Serapeum was built on a MicroATX form factor as well as my current desktop system. µATX is great for smaller desktop machines but is a bit too large for a firewall solution.

Mini-ITX seemed like the perfect option. I selected the Jetway J7F2 board with a 1.5Ghz Via C7 processor. Two compelling reasons for selecting this board were the Padlock engine, which provides hardware RNG, AES, and hashing acceleration, and support for daughter cards. Some quick OpenSSL benchmarks using the various engines provided these results:

cryptodev kilobytes per second:

type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes

aes-256-cbc 10166.19k 10492.00k 10832.45k 10520.09k 10871.68k

padlock kilobytes per second:

type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes

aes-256-cbc 69552.53k 221044.97k 475699.68k 662806.69k 745178.49k

The padlock hardware engine provides a 6850% increase in AES 256 encryption over the software based cryptodev. It peeks at about 5.7 gigabits per second. Cryptodev only achieves 85 megabits per second.

Summary of build hardware:
Jetway J7F2 VIA C7 1.5Ghz
Jetway AD3RTLANG 3 port GigaLAN daughter card
Corsair 1GB DDR2 533
Transcend 4GB CF 300x
M200 Enclosure

How to write pfsense image onto a SSD for fast installation

One question we have received since the how to build a pfsense box piece is how to quickly install a pfsense image onto a SSD. Recently we sent three Dell C6100 XS23-TY3 servers to our collocation facility but had not yet decided upon a few software items. We used the three day transit and racking time to do some basic software installation. One of these tasks included two instances of pfsense on SSD installations which we prepped offsite. When it was time to do the final installation, each pfsense node received its SSD and the units booted right up. As a result we did a quick guide on the installation after we confirmed it worked perfectly.

Copying pfsense onto a SSD

The first step in the copy process is to install the drive in the physical machine. Although we have done this for a few different SSD implementations, we are actually using an iSCSI volume setup on a Synology DS1812+ that was mounted locally. Disk management shows the following drive ready to use in the system.

The next step is to get physdiskwrite for Windows here. We are using Windows 8 Pro and thus are using the PhysGUI.exe to make the process a bit easier. One major note about this step is that since one will be making major changes to disks, one will want to run the program as administrator.

Once the PhysGUI is loaded, one will see a list of drives installed in the system. In this case we are going to use PHYSICALDRIVE5 because we are going to attach that to an iSCSI boot machine soon. For the purpose of today’s guide, we are going to use it just as we would the OCZ Agility 3 or any other SSD (we used Intel SSDs for our colocation.) PhysGUI is not an English utility so it is slightly less intuitive for native English speakers.

After selecting the correct disk, right click and open the pfsense image that you want to flash on the SSD. For this we are using the pfsense 2.0.2 stable release and are using the 4GB NanoBSD VGA version. You can read more about the versions and download here. With a SSD, we are much less sensitive to size than we are on a small USB flash drive.

Once clicking on open, and since we are using a 4GB installation, we are asked to confirm that we want to pick a capacity over 2GB for the pfsense installation.

At this point one will get a confirmation about destroying the current content on the disk and overwriting it with the disk image. Beware – you can lose data doing this so triple check before proceeding.

Once this is done, it will generally take a few seconds to write everything out. Going back into disk management one will see the image is written to the SSD.

One tip here is that you can use this to do extreme over provisioning. A 60GB drive that is brought down to 8-16GB will see considerably higher write endurance as compared to a fully provisioned drive. This can be important if one is trying to write logs to the drive.
