Maximizing Netgear WNDR4500v2 functionality with DD-WRT (USB, FTP, Samba, TFTP, Printer sharing)

The Negear WNDR4500v2 router is quite a beefy piece of hardware with advanced firmware, including plenty of features even for a maniac user like me.

I would most likely not have replaced it from day 1 however if it had one more feature that I absolutely needed: TFTP/PXE/BootP options for the DHCP server. There is where DD-WRT comes in…

WD hard drives jumper settings and SATA 1.5 Gbps limit

Hard disk jumpers where a necessary nuisance in the IDE/(P-)ATA days. Jumpers made the difference between a functional and a non-functional hard drive.
Fortunately, they disappear in the S-ATA age. Well, almost… While totally unnecessary nowadays, jumpers are still needed to fiddle modern S-ATA drives to make them compatible with some early SATA implementations motherboards.

Setting up Tenda N3 as wireless repeater

I recently purchased a Tenda N3 (micro) wireless router to use as a wireless extender in the house. Since it took me about an hour to figure out how to pair it up with my main WRT54GL wireless router, I decided to write this short how-to guide.

The Tenda N3 is a cute little thing, small enough to tuck away and forget it’s even there.

BIOS Error Codes

AMIBIOS is a kind of BIOS manufactured by American Megatrends (AMI).

AwardBIOS is a kind of BIOS manufactured by Award, now owned by Phoenix Technologies.

Several custom implementations of the PhoenixBIOS system exist in many popular motherboards. The beep codes from a Phoenix-based BIOS may be exactly the same as the true Phoenix beep codes or they may vary.

Raspberry PI as NAS

A friend of mine was wondering about using a Raspberry PI as a NAS, the question being: how fast is the PI at file transfers from/to an external hard disk connected via a USB rack.

So I booted up my PI, mounted some random 3.5 inch Samsung 160GB SATA hard drive inside another random Spire USB-SATA external (powered) rack and gave it a go at some testing.

Upgrading the SD card used on WRT54GL v1.1 running dd-wrt

If you’ve done the SD card mod on WRT54GL, you might at some point change it with a bigger / faster card. You could just replace the SD card with a bigger one, but then you’d have to install/re-configure everything set up on it (like Optware stuff). […]

RaspberryPI – first impression

I couldn’t resist not trying out my RaspberryPI which I received yesterday 🙂

I quickly recycled one of my SD cards, installed the recommended SD image and booted it up.

After the initial boot setup screen (and partition resize), you can see it running connected to a monitor via HDMI, with a keyboard, mouse and wireless adapter (Asus WL-167g) all plugged in a 4-port USB hub…

My RaspberryPI has arrived

Yay! After around 4 months of waiting, it is finally here. My very own Raspberry PI 🙂

It appears I received a rev2 board which, among other small improvements, should feature 512MB of RAM instead of 256.

The board comes packed in a nice neat pink(?!) case, together with a quick start guide giving you the essential information on how to get the thing started…

Recovering a bricked Linksys WRT54GL v1.1 using JTAG – Part 1: the hardware

I got a Linksys WRT54GL v1.1 router that somewhat worked and somewhat didn’t: it booted alright (no led errors), responded to ping on its default IP (, bot other than that, it did not respond on the web interface, nor telnet/ssh, nor dhcp.

I tried the 30/30/30 reset , tried TFTP recovery – nothing worked.

As it had the original Linksys firmware, at this point it was either a hardware failure or the only recovery course would be the JTAG reflash.
