How to Troubleshot WiFi, Wireless Network: When You are not able to See the Network in Scan List on Client

Well your problem is about Routing Table.

Give us some more detailed info about your Router.
Manufacturer: Linksys, ASUS, Etc.
Model:
Networking Scenario: Your router itself connected to Internet or its connected with other ADSL, Cable Modem?

Do these simple steps to troubleshoot wireless connectivity

1- Login to your router Configuration page ( Most cases this is http://192.168.1.1)
2- Remove all security settings, WEP, WAP Etc.
3- Go to the Network Setting page and Add New Route. 192.168.2.1
4: Now if DHCP is enabled fine, otherwise you have to configure you Computer TCP/IP settings again to use this router as Gateway. ( IP : 192.168.2.* Subnet: 255.255.255.0 Gateway: 192.168.2.1 ) Where * is anything between 2 to 253.

Hope this would resolve your issue.
Many peoples who are new to Networking get stuck over this point. Your default route of router is 192.168.1.1 and its already busy and connected with your modem so you can't use it for your system connectivity for internet surfing. There you have to add a new route for your wireless Networks (WLAN ) or even for local area Networks (LAN),

One more problem is possible while you can not see your Wireless Network in Windows XP ,

2.4GHz Wireless network could be one of the following.

1- 802.11a
2- 802.11b
3- 802.11g (Have Back end Connectivity for 11b)
4- 802.11n (Latest) (Have Back End Connectivity support for 11b, 11g)

Your Access Point or Wireless Router is configured to use 802.11n
Your Wireless adapter in Windows XP is configured for 802.11b Connectivity.

Now if your Access Point is not configured to use back end support for 802.11g & 802.11b then your Wireless adapter in Windows XP would not be able to find that network.

If Your Wireless Access Point or Router is configured to Force connectivity to 802.11g then your client supporting 802.11b would not able to see or connect the network.

Thanks.

INSTALLING WIRLESS HARDWARE

1- All than first I was to install a 30 feet tower on my building's roof witch was about 40 feet high.

2- Then I was to mount D-Link Omini Antenna on top of that tower.

(Never Forget to Use Safty Belt When You Going to Climb a High Tower)

3- After that I was to tighten the Surge Protector with Antenna's

4- At next I was to fix RF cable with other end of the Surge Protector

5- Now this time to Mounte the Outdoor Unit of RF Amplifire

6- Now witch cable we was to fix with Surge Protector other end of that RF cable we have to connect with Out Door Unit's Connector wich is labled with text " To Antenna"


7- Come to the other end where we got the Access Point and Indoor Unit of RF Amplifire, Here we have to Remove the Patched Antenna of Linksys Access Point.

8- Now we will use RF cable (witch was bundeld with Amplifire) to connect Access Point with Indoor Unit of Amplifire.

9- This is time to work on ethernet or LAN from the ADSL modem. Install the ADSL Modem. Run a LAN Cable to Access Point WAN port.

10- Install all the power adopters of Devices properly so there is no chance of lose connection or sparking in electricity sockets.

Becarefull >>> ( NEVER FORGET TO USE SURGE PROTECTOR >>>During thunder storms our 2.4GHz Devices can catch some of very high frequency radiations witch can lead to a disorder in functionality of Devices or those Devices could be dead at all <<< )


Now my Base Station is ready, time for client side installation. Let's Read about that in my Next POST.

Fist I have to have a Connectivity, latter i will install Client or User Management Linux Machine or Server between ADSL Modem & Access Point. ( You'll Read About this in Coming Posts. )

1- P-IV Computer with 1-GB RAM
2- Linksys WRT54GL Wireless Router( Access Point )
3- Repotech 1-Watt Dual Sensing Amplifier
4- D-Link 15Dbi Omini Antenna
5- Some Cat5E Ethernet Cable for LAN

Reason: Why i was to start working on Wireless Internet Service Provider Project.

We Need to Color All the Town With One Bucket of Color and its Possible......

Make a research before you start a Project. Here in this Blog I would like to tell my friends that most of the things I am doing during my WISP Project are from some great and helping online websites witch holding all the information about different topics but most of those websites are not telling all the project in a sequence or space. So that's why a newbie will face problems for understanding all that.

My This Blog Writing is only a struggle to tell people how to start a WISP in an easy way without much investment or big deals. I will try my best to keep it simple and straight so normal people could also understand this Project.

As here in my country we don't have all the latest hardware specially in Wireless Communication. In my city there was allot of people who want to have a broadband Internet connection. ADSL or DSL was also not available in all City, if available that was too much costly, some areas LAN-Network Cable was running but with a poor quality. Oh' Here I was to wake up my sleeping business interests in IT so I was to think for a Wireless LAN Network. After a few days Googling I was make an initial research about the Prices, Description and Specifications of Wireless 2.4GHz Network Devices. Then I was to purchase all that required Wi-Fi or WLAN hardware.
