How to turn an old Wireless Router to a Wireless repeater OR extend an existing wireless network using DD-WRT firmware.

AIM of Tutorial: To turn a Wi-Fi Router into a WiFi - Card or WiFi - Extender / Repeater to an existing Wireless Network. OR To extend a Wireless Network, wirelessly using another Wifi Router.

Have a spare or outdated router ? If YES ! then here is how to make smart use of it.
All you need to do first is to check the DD-WRT support and custom firmware which needs to be installed before going ahead.

My Network configuration:

1st Router Model:                   Netgear JWNR2000 (Factory Firmware)
1st Router Access:                  192.168.1.1  (DHCP ENABLED)
1st Router Wireless Network: SSID: SoftwareKing
                                               Security type: WPA2 Personal
                                               Encryption Method: AES only
                                               Security Key: mykey12233221

2nd Router Model:                 D-Link DIR-615 E4   (might work with other H/W versions also)
Flashed DDWRT ROM:        (Non- Factory) v24 Pre SP2 [Beta] Build: 21061  (Default settings)
2nd Router access:                 Default IP: 192.168.1.1
                                             Username: admin
                                             Password: admin

Assuming you have already flashed this custom DD-wrt firmware on your router, we will go ahead..

1. > Make a note of your 1st Router's Security type, Encryption Method, Security Key like I have done above. (No changes have been done on 1st router for this tutorial)

On the 2nd Router :

1.> On the main screen, Go to the "Status" Tab and then "Wireless" tab below.
1.1 Scroll down on this page to find the button "Site Survey"

1.2 Click on "Site Survey" to find the wireless networks available nearby.

1.3 Click on "Join" on the specific network to which you want your 2nd router connect to. Say for example: wireless network SoftwareKing being broadcast-ed from my 1st router.

2.> Joining the Network will take me automatically to the Wireless configuration page having the details automatically filled.

2.2 On the same page: Set "Wireless Mode" to "Client" and SAVE.

2.3 Now go to "Wireless Security" and enter the Security Type as WPA2 Personal, AES and the Key: mykey123321 (that matches your 1st router) and SAVE Only.

2.4 Now back to "Basic settings" under Wireless , you will see Virtual interfaces menu,
2.5 Add a virtual interface
2.6 Select Wireless mode: AP
2.7 Wireless Network Name: Anything you like, apart from the 1st router's ssid.
2.8 Wireless ssid broadcast: Enabled
2.9 Advance settings : Un-ticked
and then go to "Wireless Security" and enter the Security Type as, WPA2 Personal, AES and the Key: 2ndmykey123321 SAVE and APPLY.

3.> Now under "Setup" Tab select "Basic setup"
3.1 Set "Connection type" to "Static IP" and set an IP address of range 192.168.1.xxx ( I have set 192.168.1.8)

3.2 Now, Scroll below and set Router IP address to:
Ip Address :192.168.2.1
Subnet mask :255.255.255.0
Gateway: 0.0.0.0 
Local DNS: 0.0.0.0

3.3 Scroll down to DHCP settings and disable the DHCP Server and then SAVE and APPLY.

4.> Now your router will restart and will be accessible only from 192.168.2.1 in the address bar.

4.1 Assign Static IP addresses to all the devices connected to 2nd Router of range 192.168.2.xxx because we have disabled DHCP server on it. 

Note that: The 2nd router will have its own subnet, but services available on 1st subnet would be accessible from 2nd.

And then you can simply connect your 2nd router to another wall socket, may be in other room and connect your to your extended wireless network, via a wired LAN cable or wirelessly.
You will now be able to access internet and other services on all those devices connected to your 2nd router too.

Scope for improvement: Setting up configuration without having another sub-net in 2nd router.

sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.copy

2.> Add support for NTFS drives:

sudo apt-get install ntfs-3g
sudo fdisk -l

>> Note down the drive name ( my 1TB drive was listed as: /sda1)

3.> Mount the harddrive and setup mount points:

sudo mkdir /media/WD1TB

4.> Configuring SAMBA:

sudo nano /etc/samba/smb.conf

Look for ############Authentication############## line
under which you need to remove the # symbol from the line: 

security = user 

and also copy paste the following lines at the end of the file:

[WD_1TB]

comment = WD_1TB

path = /media/WD_1TB

browseable = yes

writeable = yes

public = no

read only = no

valid users = pi

Use "ctrl+x" and then "y" and then "Enter" keys to Save and close the configuration file.

5.> Save and restart SAMBA service:

sudo /etc/init.d/samba restart

6.> Add Unix users: (no need to perform this step if Pi user is already exists)

sudo useradd pi -m -G users
sudo passwd pi

Enter the password twice to confirm.(Entered password will not be shown)

7.> Add pi user to SAMBA Users:

sudo smbpasswd -a pi

Enter the password twice to confirm.(Entered password will not be shown)

8.> Setup hard disk to mount automatically even if Raspberry Pi restarts:

sudo nano /etc/fstab

Enter the following line in the last and Save:

/dev/sda1 /media/WD1TB auto noatime 0 0

9.> Restart Raspberry pi:
      
sudo shutdown -r

Edit the following lines to your needs:

“rpc-enabled”: true,
“rpc-password”: “raspberry”,
“rpc-port”: “9091”,
“rpc-username”: “pi”,
"download-dir”: “/media/WD1TB/Torrent_Downloads”,
”incomplete-dir”: “/media/WD1TB/Torrent_Downloads”,
”incomplete-dir-enabled”: true,

"rpc-whitelist-enabled": false, 
Use "ctrl+x" and then "y" and then "Enter" keys to Save and close the configuration file.

12.> Creating a Downloads directory for Transmission:

cd /media/WD1TB
sudo mkdir Torrent_Downloads

13. > Start the Transmission daemon service:

sudo service transmission-daemon start

Test if the port 9091 is open:
sudo netstat -antup | grep 9091

14.> Adding Transmission to start-up automatically when raspberry pi starts:

sudo apt-get install chkconfig
sudo chkconfig --add transmission-daemon
sudo /sbin/chkconfig --level 2345 transmission-daemon on

15.> Adding User to transmission-daemon group and set up permissions:

sudo service transmission-daemon stop

A review about Windows Phone 8 and 7.8 Mobile OS based smartphones.

The following review is with respect to Nokia Lumia Phones running Windows Phone 8 and 7.8.

Display: Super smooth touch, colour reproduction, sharp and bright display.

User Interface: Unique Metro Styled-Tiled User interface but has less support for Landscape use. You will always have to hold the phone to Portrait mode for most tasks. Has no option for customizing screen or Phone book Font size or even locking to Portrait and landscape due to above reason.

Applications: Most use-less apps from unknown developers, you will ever find on this smart phone's Windows Phone Market place. You are likely to crave for good applications.

 

Some of the best applications available are:
Nokia Drive (Offline GPS)
Nokia Maps
Nokia Music (Paid subscription)
Nokia Play to
Nokia Cinemagraph
Nokia Trailors
Microsoft Office with 360 support.
Microsoft Skydrive
Microsoft Maps
Mircosoft Zune Player
Microsoft Internet Explorer 10
Creative Studio
Lomogram
PhotoFunia
Discus
Hike
Viber
WhatsApp
Gaana
Facebook
Camera Extras
Metro Tube/ Tube Pro
In-Built support for major Email-client setups like, GMail, Yahoo, Facebook, Outlook and Custom Mail setup.

More about the Applications:

1. Zune Music & Video Player:
There are No Equaliser settings in Zune Music Player, There is one free to try application for setting equaliser settings. No 3rd party music or video player are available on market.

2. Internet Explorer 10: 
Not up to the mark when compared to 3rd party browser. UC-browser is the only 3rd party Internet Browser available in Market place.

3. Nokia Music: 
The quality of the songs is average since they are meant to be downloaded in shorter time. Also for continuing (after free subscription) you will have to pay for it later on. Note: you will have to buy the subscription from Oxigen partner and later use the key for activation.

4. Support for Google Applications:
No support for Google Products such as Maps, Drive, YouTube  Voice, Gtalk etc. except for Google Mail setup. Microsoft services are not at par with Google ones. YouTube Application on the Market Place is just a URL shortcut which will re-direct you to the IExplorer and then to YouTube mobile site and similarly for maps and other services.

5. Phone Management:
Lacks basic features for logging 3G/2G Data Usage and last call duration  though there is an app for the same called "Counters" its based on pre-inputs from user, which will require you to define your monthly limit for calls, SMS and Data Usage Manually.

6. Skype / Viber:
Skype works just fine.
You are likely to miss a few calls or messages on Viber, if you did not pay attention to your phone or Notification Bar. 

7. CinemaGraph: The most amazing app on the Market place ( Thanks To Nokia ) allows one to record a short video and allows you to specify which part you want to keep animated (moving) and which parts to be kept still along with loop time settings.
The size of each snap is hefty more than 4mb each for obvious reason being a GIF animated image.
The app is now available for IOS platform too.

8.Nokia Drive:
The best GPS application you will ever come across! why ? because it works in offline mode too ! with distance covered, trip meter settings, Voice navigation and Speed gauge. All you have to do is pre-install maps of your region and Voice files of the languages you understand.

9. Microsoft Skydrive and Office360:
They work flawlessly and are well integrated with other applications. Though there is ZERO support for 3rd party cloud storage providers such as Google drives and DropBox.

Games: 
Temple Run 1 and Mortal combat were released a few weeks before. Angry Birds Star Wars and Fruit Ninja are free to try with locked levels.
Temple Run 1 seriously ? aren't these obsolete games according to you ? Imagine Android/ IOS ppl playing "latest" & "Free" and discussing about them on playstore and Appstore and Windows phone ppl yelling and crying (including me) for apps and games.

>> Most of them cannot be played because of limited RAM of 512MB and even 1GB (For temple Run 1). 
Games will come no doubt but a price or free to try if "NEW", and 100% free If OLD.
Do not expect any new games any sooner.

Camera: Best in class even comparable to all the Android smartphones and Iphone 5 out there. Though Panorama feature is not as smooth and simple as Iphone.

Tethering support:
No USB / Bluetooth Internet sharing supported. Only WiFi internet sharing supported with which, you are likely to drain all your battery juice in a couple of minutes of use.

OS Security:
Its a very secure mobile operating system, you will not have to install an Antivirus application on this phone.

Others:
>> No file explorer  or support for exploring LAN shares on your PC. You will need to setup your own FTP or Web server and browse your files from browser only.

>> Support for SAMBA shares is also not present and is limited only from a free to try app.

>> Push SMS notifications after a call or SMS or Data Session are hardly shown. Notification Bar is faulty.

>> You cannot manage your songs, Pictures or Videos without having to install Zune Software for Windows and MAC users. Linux Users will have to rely only on Bluetooth for file sharing.

>> Lacks remote access tools like Teamviewer and Remote desktop Connection is another Paid application.

Price: Nokia have slashed prices of Lumia 820 from Rs. 27000 to Rs. 24000 in just 3 months of its release following with Lumia 920 also.Its just not for the price you will paid for it and the functionalities it will provide.
