BSNL wifi modem - connectivity problem

BSNL provides wifi modem in colloboration with router

manufacturers like Nokia-siemens,Teracom etc. Modem works well in
wired connection as well as in short range(100m) wifi connection with
laptops,PDA and tablets. But sometimes, the wifi connection is denied
by the router. This may due to many reasons like wrong PP0e
configuration, poorly configured router etc.

 Recently, when i tried to tweak my friend's new teracom wifi
router to connect it with Samsung Start II wifi mobile. I tried changing
the ip,gateway,subnet,changing the wifi protected to open
connection,but in vain. But the wifi connection in my Nokia- Siemens
router works well without any problem.
    One day, i checked and play with all the settings of my wifi
router, it seems like i have accidentally changed the MAC filter settings
as enabled. After that, my wifi connection seems not working with any
laptops or mobiles. Viola! I found the reason for the denial of wifi
connection to myself and my friend as well. Here the interesting fact is
that wifi connection is denied, even if you enable the MAC filter in
BLACKLIST mode or WHITE LIST mode unless you add mac address to
the list. That is ,it does not allow any new wifi connection if you enabled
either of them.

 To change the settings follow the steps:
1.Open your browser and point it to ip 192.168.1.1
(192.168.1.1 is the default gateway address,if you changed this,the
above ip will not show anything. To find the ip of your router, just open
command prompt and type ipconfig,you will get default gateway
address which can be used instead of above ip)
2. Give the username and password, default is admin for both.
3. Find the MAC filter option, this option location varies based on the routers, it commonly found under the security options of your router.
4. Change it to disabled. Reboot your router. Thats it.

NetWorx – Free Bandwidth monitor that saves your bill

NetWorx is a simple and free, yet powerful tool that helps you objectively evaluate your bandwidth situation. You can use it to collect bandwidth usage data and measure the speed of your Internet or any other network connection. NetWorx can help you identify possible sources of network problems, ensure that you do not exceed the bandwidth limits specified by your ISP, or track down suspicious network activity characteristic of Trojan horses and hacker attacks. Click here to download
       It is a must for the users who have broadband with limited data usage.Just give it a try,its awesome.

The program allows you to monitor all your network connections or a specific network connection (such as Ethernet or PPP) only. The software also features a system of highly customizable visual and sound alerts. You can set it up to alert you when the network connection is down or when some suspicious activity, such as unusually heavy data flow, occurs. It can also automatically disconnect all dialup connections and shut down the system.
The incoming and outgoing traffic is represented on a line chart and logged to a file, so that you can always view statistics about your daily, weekly and monthly bandwidth usage and dialup duration. The reports can be exported to a variety of formats, such as HTML, MS Word and Excel, for further analysis.

Key features of networx is shown below..

*You can select the appropriate interface to monitor,ie you can choose your ethernet driver or dialup modem(if use mobile as modem with your pc suite) or to monitor both.

*Networx produce daily reports,weekly,monthly reports based on your usage.

*In addition to monitor data usage,it also contains other vital utilities like ping,trace route with advanced settings to monitor any suspicious activity in your system.

Networx provides the significant settings which make this software as my favourite one, is that it differentiates the off-peak and on-peak usages. For example,if you have broadband with limited usage in the day time and unlimited usage during the night time(some ISP'S like bsnl,mts,reliance are having plans similar to this).
 If you're having bsnl broadband with unlimited night usage(2am-8am), you can make the settings as follows,
*Right click the networx icon in the system tray and select settings, as shown below;

*Select advance tab

*Now you can see the week and time grid under the Hours in 24-hr format section.
*Make the grids between 2am-8am as green for all the days of the week(green indicates the off-peak time).
make other grids as yellow which indicates the on-peak time ie daytime.
*Click apply and ok button.
By this way,you can track the daytime usage by simply ignoring the night usage,so that you cannot exceed your data usage limit.
Now double click the networx icon in the system tray,you can see the usage statistics screen,select monthly or daily report tab,click the display menu as shown below,

 If you select on-peak hours,you can get the daytime usage results,like wise you will get the off-peak usage(2am-8am) separately.
Nice,Isn't it?
