1. Verify about the wires carefully
The wire which is connected to your house should be in the direction like a straight line and it should be a single line without any joints. The wires are away from electrical lines, if the wire with joints or coiled or near power cables, your phone might work fine but the DSL link may not hold and its may not work accordingly.
2. Parallel telephones never void the splitter.
The splitter does the job of separating the high frequency ADSL signals from low frequency telephone signals. If the splitter is not installed correctly, the broadband connection will go down every time the phone rings. Any parallel phone connections should be after the splitter and not before. The line from the exchange should first enter into the splitter’s line jack.
The ADSL Modem should be connected to Modem/DSD jack of the splitter and the phone should be connected to the phone jack of the splitter. A two way jack may be connected to this phone jack to install your parallel telephones. The wire leading into the modem should not be running parallel or close to electrical wiring.
3. Signal to Noise Ratio (SR)
Check your line SNR. for doing this, 1st u want to enter into the ip address in your browser by typing http://192.168.1.1 and asked for user-name and password. The default user-name / password is admin / admin (except for the modem Utstar300R where it is admin / utstar). In Device Info Statistics ADSL, you will be able to see the SNR Margin and Attenuation. This is one of the distinctive way to see the SNR in Modems. However the procedure might vary with modems and you need to look for words like ADSL, Statistics, Summary etc.. to see the SNR. The SNR should be higher than 20 though anything above 10 is just enough. The Attenuation should be as low as possible. But if the attenuation starts going higher than 40 and SNR going down below 10, it is the time to complain about the line condition to concerned authorities.
4. Experience about mode of functioning
Broadband in Bridge mode or PPPoE (Point to Point Protocol Over Ethernet) mode. For Bridge mode, a dialer icon will contain your user-id and password and we need to click icon to get connected to broadband notwork and thereafter we will open our browser to view web-sites.
The other method which is widely used is PPPoE mode, where your user-id and password will be available (configured) in the modem itself. In this case, after switching-on the modem and when DSL (Link) light is glowing steadily, you can start browsing straight-away. We recommend you to first switch on your modem and then switch on your PC/Laptop. For this, if the user is in Unlimited plan it will safe for
5. Check Your Account usage
It is always advisable especially for users not in unlimited plans to Check BSNL Broadband Data Usage periodically. You can change your password but please remember that whenever you change the password using the web-site, the same password-change must be carried-out in modem (for PPPoE mode) or in the dialer (for Bridge mode) also. Besides, giving the usage details session wise, the usage records will also reveal possibilities of your machine sending information without your knowledge due to cookies or spyware or virus attacks. Normally the upload will be much less than the download for browsing related activities. If you use chat (text/audio/video) like skype or any VoIP service, then the upload will be equal or more than the download for these sessions. But if you donot use such chatting mechanism still find the uploads more, then it is surely due to some unwanted cookies or spyware/virus attacks.
6. DNS Servers
DNS servers are used to answer the URL like www.google.co.in into an IP Address like 220.127.116.11 which is required by routers to take you to the website. The DNS server IP will automatically be available in the Modem for PPPoE mode of working. Ensure to keep the modem settings to acquire the DNS IP automatically please. For Bridge mode of working, your machine will be getting the DNS IP automatically. You may check it by giving the command ipconfig /all in the command prompt. It will always be better to assign an IP address to your Ethernet/USB/Wireless adapter to which the modem is connected. To set this, go to control panel, click Network connections and under the “LAN or High-Speed Internet “ there will be icons Local Area connection, Wireless Network Connection showing the NIC card , USB port, Wireless adapter to which your modem is connected. Right click on the icon, select Properties, click on Internet Protocol(TCP/IP), click on Properties, click on “Use the following IP address” put the IP address as 192.168.1.10, subnet mask as 255.255.255.0 and default gateway as 192.168.1.1 and Preferred DNS as 192.168.1.1 Click OK and then click Close, Use different IP address like 192.168.1.11 or 12 to each NIC, USB & Wireless adapter. One can also use the public DNS like 18.104.22.168 or 22.214.171.124 as preferred DNS but if some sites are not opening using this DNS, service providers will not take the responsibility.
7. Wi-Fi Connectivity
Linking to Laptop having Wi-Fi capability with wireless ADSL modems (Type II and Type –IV) is very simple. At the very first time, you switch on both the modems and Laptop, the wireless icon on the taskbar of the Laptop would say “Wireless Networks Found”. Just double click on the icon and follow the instructions, selecting Network Authentication as WPA-PSK (or WPA-Personal), Encryption as TKIP and providing the Wireless security password (Key) given by BSNL. In some Laptops, you need to right click on the “wireless network connection” icon either in the task bar or in Network connections under Control panel and select View Available Wireless Networks select the Wireless Network Name or modem’s SSID (Service Set Identifier) and proceed as given above. If you get some error message like “Limited Connectivity” on the “wireless icon” of the taskbar, you need to assign an IP address to your Wireless Adapter as detailed in the Step 6 above. If your modem is working in PPPoE mode, you can even connect your Laptop through wireless and PC through Ethernet and simultaneously access the net through both PC and Laptop.
8. Placing Wi-Fi Router
Though the wireless signals from the Wi-Fi router (modem) can reach wi-fi enabled laptop within the range of around 50 meters, the brick walls and reflective surfaces will weaken and bounce the signals respectively. It will be better to place the Wi-Fi Modem on a higher place to avoid physical obstructions. Another main source of interference is the cordless phone. Keep the router as far away from the cordless phone or choose cordless phones that use different frequencies. To increase the wireless range one can also use a wireless repeater purchased from local market. Before purchasing, ensure from the vendor, it supports the wi-fi router which you have.
9. Wi-Fi Security
The security options of wireless router should fully be utilized to avoid someone from your neighborhood accessing your modem. The wireless signals might reach the neighboring houses, and if the security options are not enabled, there is every chance of mis-use of your broadband connection. By default, BSNL gives your wireless modem with security enabled. But by some chance, if the modem gets reset, the settings might be lost. Hence it is advised to check the security options are enabled. Customers can visit the modem webpage as stated earlier and check the wireless security options. The very basic level of security is by giving the wireless key, which will be asked by the modem when a Laptop is trying to access the modem for the first time. There are two types security key algorithm. One is WEP (Wired Equivalent Privacy) and another WPA (Wi-fi Protected Access). The WPA is more secured and recommended by BSNL. The next (advanced) level of security is – MAC Filtering by which only your Laptop/PC will be permitted to access the modem, even if someone knows your security key. The detailed procedure for the above two levels of wireless security is published in our website www.chennai.bsnl.co.in under the heading Broadband Wireless Security. The default SSID of the modem may also be changed as per your desire and it may also be made hidden (turn-off SSID broadcasting or Hide Access Point) so that others will not even know about your wireless modem. In this case of Hidden SSID, your Laptop will be connected to the modem as you have already configured for the connection in your machine.
10. Look-out for bandwidth (information measure)
Many applications like Windows updates, anti-virus updates and other software updates will be using the broadband connection in the background. Some of these updates might ask for confirmation before downloading, many may not even ask and will be simply running in the background which will affect your browsing / download speed. One can find-out the applications which are running, by going to the Task Manager (Press Ctrl+Alt+Del keys together to get into the Task Manager). You may shut down such of those applications which are running without your consent. But beware that shutting down some vital applications required by your operating system inadvertently will cause hanging of your system. Windows updates, Anti-virus updates etc.. could be scheduled to run when your system is free and you are not browsing. This will help in utilizing the bandwidth effectively.
11. Risk with Virus
You might some time feel that your broadband was quite good some time back but it is slow now a days. One of the major reasons for this is the infection of Virus into your machine. Adwares, spywares too will affect your speed. Hence it is very important to have a good anti-virus software and spyware, adware detectors in your system. Regular updates to these software and Windows updates are also a must. Use only legal version of Windows to get the system in a good condition.
12. Mindful about free wares
13. Windows 7/Vista
Specifically no extra settings are required for Vista / Windows 7 Operating systems. You may see something like “Unidentified Network” (mostly when connected through wi-fi) and hence may have to assign the IP address, gateway, DNS server as detailed in step 6. Typically Control Panel Network and Internet Network and Sharing Center Change adapter settings (Manage Network Connections in Vista) Right click on Wireless Network connection Properties Internet Protocol Version 4(TCP/IPv4) Properties and then, assign IP, gateway & DNS. You may remove the tick mark of Internet Protocol Version6(TCP/IPv6), if any browsing problem arises.
