Saving WRT54G

Posted by rizal on Dec 23, 2006 in wireless | 0 comments

One week after passing the RHCE, I decided to upgrade my Linux box to Centos 4.0.
It was not easy – (I survive the installation ) the downloading
process which took days~ mainly due to the unstable connection on my WRT54G.
Kept on disconnect every hour most likely due to some interference . I
suspected it was probably due to foreign wireless station had the same
channel(default channel 6)  but then when tested by Netstumbler
it was using 1 not as what I suspected. Hmm.. interesting , could it be
due to the 3G signal from the indoor BTS inside the data center?

One of my solution to the problem was a simple restart to the AP but
that was only temporary solution. It kept on disconnect every now and
then and people started to complain why it happened that frequent.
Darn! Yup! I am the one who proposed the AP later bought it from Low
Yatt  so by default I am the one responsible for any problem with
the AP.
Later I decided to upgrade the firmware to the latest  version
~3.0.36 and it worked OK for a while and before disconnected again.
Ouch! Found this Linksysinfo.org  with a huge collection of unoffical wrt54g firmware ( I love open source!) to choose from.
Reading from DSL Report I decided to give the Alchemy 1.0  a
try. Half way updating the new firmware (wirelessly) I was disconnected
and found out later the AP now is a useless brick! There is no way that
I can get the Setup Page even though I can ping the machine after reset
it to the factory default.
Thank Allah I found this website from Google . All I need was a screwdriver (found one inside my bag) and some courage to void the warranty .

After put back the firmware to Alchemy , it works fine for a while (my iso was downloaded) thanks to this article  ( do add -c after wget!) before the problem started again!

Wifi Hacking Revisited

Posted by rizal on Aug 3, 2006 in wireless | 0 comments

I am reviving my old wifi hobbies again. It was “dead” for a while since I broke my Orinoco pigtail connector – no pigtail means all the antennas were no use. But since I received few emails regarding wifi from my new friend, arwana at ITTutor.net inspired me (good reason to start back!) to revisit my wifi hobbies again.

For a start, I already placed an order for MC card connector for a new homemade pigtail from Ebay. The N connector and RG316 was still unused (untouched?) in the toolbox so the only missing elements now is the to get the right crimping tool!

My idea now is first to bring up my Wireless Community project up and running(maybe with Chillispot ) and later invite friends of ITTutor.net to my home at Nusa Subang to have our very own version of Home Brew Antenna Shootout.
The idea is simple. Bring all your DIY antennas to my place and we shoot them right to my house from the playground infront – and find the best antenna design with best signal reception!

Some gadgets in my toolbox.

Few N connectors and the panel mount, copper wires and a tin can. Also the RG316 cable for the pigtail,just ordered MC-card connectors from Ebay hope to recieve it soon. The only thing missing was the Orinoco card! I loaned all my cards to friends since I got my Centrino Thinkpad.

Panel mount N-connectors female (right) and N connectors male.

This antenna will be mounted infront of my house with Senao 2611 AP.
