Installing WiMax By Yourself

If you are a techie guy looking to install wimax yourself ( and not depending on those service persons), this is the right place you have come...
 [1] First be sure that the username and the password you have received is correct (although this can be ensured by the fact that the username is generally a suffix or a prefix of your landline no.(the phone no. as in the payment receipt) with some other letters or digits and the password is "password") [GENERALLY]

 [2] Connections: the easiest part: WiMax consist of the following compos:
       [a] The CPE (the antenna)  [b] The PoE (Power over Ethernet) which will give power as well as the data connectivity with the receiver   [c] Connecting cables (RJ-45) and power cable for the PoE...

Now insert the PoE cable into the WiMax CPE and connect the other end of that cable to the PoE port of the PoE.

Note that the PoE cable is no any other cable but your normal LAN cable so dont bother about using only the cable that came with the box. U can use your own cable of your desired length.

Then another port of the PoE i.e. the data port will be connected with a lan cable to the lan port of you computer or lappy.

That's it. You are now over with the connectivity step. Dont bother about the position of the wimax for now  whether it is outside or inside or to which direction it is facing...

[3] As soon as you connect your computer's lan port with the cable your computer must respond to some network activity, though be sure that the IP settings are all set to automatic including your browser's proxy settings.

If no such activity is seen i.e. the lan symbol is still crossed like this  then either your PoE is not switched on or the PoE cable connected to the WiMax is not connected properly or the lan cable connected to your computer is not proper or any of your cables are bad..replace it and see.

[4] Look for the network properties where you can see the sent data and receipt bytes.. if all is well then the no. of received bytes will be higher then the sent bytes.

[5] Congratulations!! the connectivity is set up. Now it is the time you take the outdoor CPE (the antenna)
attached properly to a long pole to outside and look for a place with less obstacles like tree, buildings etc..

[6] Search for the default IP address(generally 192.168.X.X) of the CPE which can be found in its manual and write that on your internet browser.. and hit enter.

[7] A page should come asking for password (generally 'admin' or 'password') also can found on the manual.

[8] Successful authorization should bring you  to a new page to the status of your connectivity and normally it  would show you disconnected because the wimax CPE would not be in the right direction.. So now haunt for the direction..

[9] Three parameters should be noted while moving/rotating the CPE for best results viz...
       [a] RSSI which should be less than -80 dBm
       [b] CINR which should be greater than 18 dB
       [d] TxPwr whih should be greater than 18 dBm

These fair combinations should result in your connectivity to the internet. Please check for RSSI first, then for the CINR and then the TxPwr

AND PLEASE PLEASE PLEASE DO NOT make hurry in changing the directions of the CPE because the changes in the values are very fluctuating and hence wait for sometime and see the values to settle because I have seen values coming from -128 to 76 within 15 to 20 seconds..

AND PLEASE do not be fooled by reflected signals because WiMax do receive reflected signals as in my case below (with forest and buildings just in front of the CPE with RSSI -78 and CINR 22 and connected with 900 kbps in 1mb  plan) and in such case the connection may disconnect frequently...

****HAPPY WiMAXXXXing****
