Need Wifi Repeater

My current project is related to my working environment at a teacher's prep college. There is a TP wireless box providing Internet to wireless users at the college. However, as is often the complaint about wireless, the range is aweful. The transmitter is mounted in the corridor of the bottom floor just outside room #9. I've picked up the signal without much problem in #10. I've tried to pick it up on the second floor and am able to in the Secretary's Office quite well. I can also pick up an intermittent and weaker signal in the Teachers' Room. However, in #4 I usually have such a weak signal that there is no connection or the connection is lost as soon as it is made. I also want to provide connectivity all the way to #2.

So my search began for how to use a laptop as a repeater for the signal, via either Windows or Linux. I found the MeshBox project, which provides a free, bootable CD that does exactly what I was looking to do. I'll have a test run next week and report on how it went.

Useful Codes

Here is some useful info from a so-called forum:

*#06# - displays International Mobile Equipment Identity (IMEI) number;
*#92702689# (*#WAR0ANTY#) - displays warranty information; to exit this mode you have to switch your phone off then on again;
*#7370925538# (*#RES0WALLET#) - resets wallet code with wallet contents;
*#2820# (*#BTA0#) - display BlueTooth Address for mobiles with Bluetooth;
*#7780# (*#RST0#) - normal reset, restore phone to factory defaults;
*#7370# (*#RES0#) - deep reset, restore phone to factory defaults and format all user data;
*#0000# - firmware version information;
*3370# (*EFR0#) - activates Enhanced Full Rate codec (EFR) (your phone uses the best sound quality but talk time is reduced by approx. 5%);
#3370# (#EFR0#) - deactivate Enhanced Full Rate codec (EFR);
*4720# (*HRA0#) - activate Half Rate codec (your phone uses a lower quality sound but you should gain approx. 30% more talk time);
#4720# (#HRA0#) - deactivate the Half Rate codec;
*#67705646# (*#OPR0LOGO#) - removes operator logo on some phones;

To format Symbian platform phone press simultaneously 'Green' + '3' + '*' and at the same time turn phone On. Be carefull, this operation will erase all phone contents! That operation is similair to deep reset code (*#7370#) function and its helpfull when you're not able to enter code from keyboard in cases when phone just won't startup.

Power Button Tip


If you press the button for a short moment, the menu with the profiles is shown on the display. If you press one more time, the mobile turns itself off. You can use the up and down cursor keys to scroll and enable a different alert setting.
The 54# Tip
Type 1#, 2#........54# on the keypad (when you're not in the menu) to get the phone number used for with this key when speed dialing.
Toggle Headset and Auto settings
#1: Try Connect the pin-out 1-2 (in front from the right.) to toggle headset settings (The phone will think that you ar using a headset - "headset" is displayed in the LCD)
#2:Try Connect the pin-out 2-3 (in front from the right.) to toggle auto settings (The phone will think that you are using it in the car - "auto" is displayed in the LCD)
Call Menu
(In a call) you can press and hold down the menu button for 3 sec. and a menu appears. (transfer, mute etc.)
Quick SMS Typing
When typing SMS messages, you have to wait some seconds before you can type the next letter if it is in the same button than the previous one. For example try to write the word "letter", you have to wait before you can enter the second "t". A much faster solution is to press the # button twice and then the letter "t".
The Reboot Trick
1. Go to calendar ( menu - 8 )
2. Make note / reminder
3. Enter some text into the edit box
4. Hold clear until whole text is cleared, then press back
5. Press 0. Main screen is shown but a space appears on the screen. You can't see it of course.

There you have it! I'm not sure which codes work on the S40 series, such as my Nokia 6300. Some of them are scary! ;-) I've put them here for your and my use.

More Memory for the Nokia 6300

As soon as I began putting images, video and music on my phone, the included 128M card was too small. So I purchased a Kingston 2G card with USB micro reader for 60 zł. Now I have plenty of space.

With space comes necessity for organization. So I've created an efficient directory structure of folders as well. One folder I found essential at the start was a TESTING folder within my PROGRAMS folder, as well as a FAILED folder. You might think I should delete the failed programs, but I found that sometimes they simply need a little attention to detail to kickstart.

I'm relatively happy now. :-)

Nokia 6300 and Linux

THE EASY PART

Hooking up
Well, I got my Nokia hooked up to my laptop. The cable was a standard camera cable that cost about 30zł. I plugged it into my HP Pavilion zv6000 running SuSE Linux 10.3. The Nokia told me I had a USB cable connected and asked me to "Select mode". I pressed OK. Then I was faced with a menu: 1. Nokia mode 2. Printing & media 3. Data storage. Cool! I chose Data storage, hoping it would give me access to my folders and files of my Nokia on my HP. POP! "127M removeable media" window appeared. I clicked Open in New Window. There they were! All of the contents of the 128M card of the Nokia. Don't ask why it reported it as 127M. :-P The point is that it works and easily!
Contacts and SMS
Next, I had to test access to my Contancts and SMS'. So I had to explore the phone software that comes with Linux. I hit upon one that autodetects the phone and it found my Nokia 6300 properly! Voila! There it was, connected. The program was Wammu.
Photos and Text
I transfered photos I had taken around the world onto my phone, set one as the wallpaper and set the folder as a Screensaver in Slideset mode. WOW! The photos look as amazing as they do on the computer! This is working better than I expected. So I tried an OpenOffice .odt file, since the OS is Linux. To be fair I also copied a .doc file to the phone. Neither of them would open on the Nokia though. So I tried a plain text file and it worked fine. Now my recipe for my mom's pancakes is on my phone. ;-) Love them with maple syrup and a little butter!

AUDIO

Ok, those aspects were solved. A major one was left to be tackled: audio. I moved a ringtone to my Media card and accessed it on my computer USB connection to the phone. I tried converting it to .ogg, which really compresses the file, but the phone couldn't recognize the format. So this required some research. I found that .aac (the Nokia favored audio format) is a version of MP4, which itself is a version of MPEG. Be careful! Even now I accidentally type .acc rather than .aac .
Codecs
The open source codecs that allow decoding/encoding of .aac are FAAC and FAAD2. So here are the programs for Linux I found easily by a search within the YAST Software Installation interface that provide access to them. Floola (iPod interface, which allows converting for iPod formats, including .aac), jRipper, ogmrip, audiokonverter, encode2mpeg, MoreAmp, pacpl and shrip. I will try these in a moment. I just installed them. :-)
Audio Conversion Programs
Ok, so I learned from the settings in a program that FAAC is the encoder and FAAD2 is the decoder. MoreAmp was screwed up in the font size, so words were overlapping and impossible to read. I haven't seen this problem in a Linux program in many years! How shocking to see it now! Also, there is no clear way to transcode a file. So I moved on to jRipper. It was more hopeful. It appears to have the capability to convert mp3, aac and others. You can work on files on your drive, not just from removeable media (DVD and CD). However, when I selected the directory from the Nokia's media card, which has the .aac ringtone, the jRipper only showed me the two mp3's I placed in the folder. It couldn't find the .aac file. Szkoda!

Next program...ogmrip seems to only handle video files. I tried and tried to no avail. :-P Next! ... Floola requires an actual iPod. HA!!! If I owned Linux, do you think I'd also own an iPod!!!??? Next! ... audiokonverter should do the job. This might require the command line, but I'll search for an entry in the SuSE menu first. Well, I couldn't find it and it doesn't run from the commandline. So either I am misspelling it by capitalization or it didn't get installed. I am firing up YAST to see. Meanwhile, from the terminal window I tried the final three programs (encode2mpeg, pacpl and shrip) and discovered they are all commandline programs. Hmm...well, I could write a quick script to do what I need and then just run that script in the directory that I temporarily store the .aac/.mp3 files in to convert without having to worry about attributes to the commands. If you're lost just treat me as if I have lapsed into a brief mood of schizophrenia. Now I'll continue with normal talk again. ;-)
Audiokonverter
Well, I tried audionkonverter. It actually installed itself so that you can right-click on your file and choose the action menu and convert to, then the new file type you want (i.e. mp3, ogg, etc...). That was cool! It isn't just a commandline program after all. However, it did not convert my .aac file to .mp3 successfully. None of the other file format succeeded either. So I give up on that program. NEXT!!! Pacpl looks interesting. There is also another package that integrates it into Konqueror, but I'm not yet sure how. We'll soon see!
Pacpl
This is a perl program that accesses the necessary libraries to convert audio formats. Perl is rather fast, so I'm not afraid of lag. I'm more afraid of dependency hell, since any perl program may require other perl packages, yet not let YAST know at the time YAST is installing the perl program. Then you have to try the Perl repository and a special interface for it. YUCK!!!

VIDEO
3gp Converter looks the most promising. It is a Komander script, so that must first be installed. Then download the appropriate RPM of 3gp Converter. Under SuSE it is safest to right-click and install an RPM with KPackage. Believe me! When you first install an RPM you should mark the Replace Files and Test boxes. Once you have a Result=0 then it means nothing went wrong. Then unmark Test and clock Install again. :-) I have Komander, but this 3gp does not know it. So I gave up on it.

I found the perfect program for video transcoding for PC<->Nokia on Linux. It's called Mobile Media Converter. This makes the transcoding a piece of cake with drag and drop list building, preset conversions by button (for novices) and tweaking of parameters for the slightly more advanced user. In short, IT JUST WORKS! :-)

PDF, WORD, EXCEL, OPEN OFFICE, etc...So now I want to read pdf's, doc's, xls', odt's, etc... What do I do? I found some programs made by Zesium Mobile. There is Mobile PDF, DocViewer, and MobiWord. Ok, these little programs do not substitute for OpenOffice nor for MS Word/Excel, but they will get you by in a pinch!

Mobile PDF shows PDF's, but without graphics. DocViewer shows excel spreadsheets, but the lines wrap a lot and the original may be difficult to dicipher. You'll just have to try it yourself. MobiWord allows you to create .rtf files in a knockoff of a very old Word '95 interface. At least they work, though they do not accomplish everything I want with my phone yet.
