Linksys WRT54G Hacking Part 4 – Changing The Firmware

No Comments

When my linksys arrived it was already running a non stock firmware Tomato Version 1.27vpn3.6.4b664ba6 now as a previous user of dd-wrt I decided I would go back to that. First off it's a bad idea to go from one non stock f/w to another, stock to non stock gives you the best chance of an upgrade without bricking. 

So I followed this procedure

Hard Reset (aka 30/30/30 reset):

The following procedure will clear out the NVRAM and set dd-wrt back to default values:

  • With the unit powered on, press and hold the reset button on back of unit for 30 seconds
  • Without releasing the reset button, unplug the unit and hold reset for another 30 seconds
  • Plug the unit back in STILL holding the reset button a final 30 seconds

I downgraded back to stock WRT54GSv3_4.71.4.001_fw did the 30/30/30 again then upgraded to dd-wrt.v24_mini_generic however I found it didn't had support for SD cards in it which is a future mod I have planned so again I did a 30/30/30 and downgraded back to stock before reupgrading to dd-wrt.v24_std_generic

One of the first things I did was enable SSHD via the 'services' tab however when I clicked apply setting my browser was forwarded to a blank white screen @ http://192.168.1.1/applyuser.cgi I tried the same again in a different browser and it worked fine, it may have been a remnants of an old session cookie or something.

Linksys WRT54G Hacking Part 2 – Adding Serial Ports

No Comments
Requirements
Soldering/de soldering equipment
1x 10 way header ie from ebay or single a strip and cut your own from maplin

The WRT54G has two serial ports you can access via the 10 pin JP1 header which is found near the front of the router board next to the lights. I ordered some 2×5 10 way headers from ebay.

Here is a picture of where JP2 is, it's the 10 way one on the right the one on the left is a 12 way port used for JTAG which i'll cover later.

The holes in mine weren't pre soldered but i've seen others that have been so if they are you'll need to remove it first. It's then a case of inserting the header with the shortest pins exiting the bottom of the board and then soldering each one.

and how it looks from the top

Linksys WRT54G Hacking Part 1 – Opening The Case

No Comments

Now i've been fortunate enough to have previously opened a fair few of these using the widely published method of having the router upside down with the back towards you and pushing the the front two feet away from you. Now on more than one occasion I've managed to break or bend plastic and clips so came up with my own way of doing it and not had any breakages yet.

Place the router on it's side on a flat surface and put the palm of your hand and thumb in between the the legs and gently push until a small gap is created between the blue facia and black casing.

Next insert a small flat head screwdriver between the facia and body

Next gently move the handle of the screwdriver towards the rear of the router which will open the gap all the way down

Then simply 'unhinge' the facia away from the body

Linksys WRT54G Hacking

No Comments

So after modding a WRT54GL for a job at work I decided that I would do the same for my own one but add as many hacks as I can. This is bit of a nostalgia trip for me as I still have some linksys routers from about 10 years and remember liking them then. They've proved popular in the community as being very hackable due to running linux.

Time to switch

No Comments

Since the creation of theoutpost (TOP) in 2005 it's been run on serendipity (S9Y) blogging software. For some time I have had problems with the WYSIWYG editor and not being able to format posts correctly. After a lot of pondering i've decided to make the switch to wordpress due to it's increased functionality and plugin availability. One thing I do like about TOP currently is the theme style and layout, I enjoy the simplicity of it and the fact I was able to easily edit it to meet my needs especially on the gallery side of things. For what seems like an age searching 100's if not 1000's of wordpress themes I think i've finally found one I like that keeps in line with the current clean minimal layout. 

Tonight I will do a backup of TOP and then run the importer script to get everything over to wordpress when I get a chance. I can already foresee it's not going to be that straight forward but fingers crossed. 
See you on the other side………….

That’s right it’s been confirmed that Red Dwarf X will be coming to Dave on 4th October 2012 for 6 episodes. I’m looking forward to it as I am a closet dwarfer I just pray to god it’s better than Back To Earth (BTE) which sucked more than Kryten’s vacuum attachment.
