Who didn’t have problems with the Internet speed at least once?
I hate to be run through standard procedure, You probably hate it too. If your problem is the Internet connection you will probably have to talk to an agent anyway, but, (with the help of my article), you will know from the start what’s wrong with your Internet connection.
Step 1 – Never Assume
First think I have learned in the Call Center was to never assume. Many times, when people call the Help Line they have a “pretty good idea” of what’s the problem. Usually they are wrong. Don’t do this mistake, do not presume or, do not presume without checking the facts. We hate the Call centers for making us do stupid things, check things that we don’t need to. The truth is that in most of the cases we overlook things and going by the book helps.
When we open up a browser and there is an error message “Page not found” we immediately assume that the connection is to blame. In fact many times this is just a temporary p
roblem of our home page site. Try a different address to see if the connections is down or the home pages’s website is down. Try google.com for instance or ibm.com, or bing.com; if these don’t work it could be the connection
Step 2 – Try a reboot
Almost every time a reboot solves the problem. This might sound anecdotic but it actually works in many cases. Reboot the computer, reboot the modem, reboot the router behind the modem.
Isolate the problem
First of all we need to know that the problem is not in the network.
Use a computer that you are sure is not infected by any Mallware. Connect it directly to t
he DSL device, cable modem, or other type of modem.
Do not use the wireless; connect the computer with a network cable. This way you are testing the connection and nothing else.
As already mentioned, you need to make sure your computer works fine and is not infected. Use antivirus andantispyware if needed.
If you are not sure about the health of your computer you can always boot from a Live Linux CD. On the Live CD you will have a browser and other useful tools.
Once the system is up and you are connected to the Internet, test your connection with one of the free online services. Google-it and you will find many online DSL speed test
websites. If the speed is OK then, the problem is in your computer, or your network, go to step 5.
Step 3 – Modem troubleshoot
If the DSL speed test failed, (no connection or slow speed), you have a few things t
o try before calling the ISP
Usually, for a DSL connection, the telephone line is shared with another device, a fax or a phone. Some of us have a separate line for DSL or they don’t even have a phone line, they only have a dry loop. If you don’t understand any of these you most likely don’t have it.
If you share the DSL line with another device you need to connect this second device through a DSL filter. I must stress: EVEN IF IT WORKED before without it, you must have the filter.
DO NOT run the DSL line through a filter, you’ll only break your Internet Conne
ction, only the phone or the fax, or Credit Card processing device, etc…
Check all the physical connections of the Modem Device, R6 or RJ11 or the RJ45 connectors and make sure that they are tight they don’t have the locking pins broken, etc…
For a DSL connection the length of the phone cable could be critical, so use the original cable, (the short one), provided with the modem at least for the testing period. The reason is because the length of the pair from the CO to your place can be at its length limits, it happen
s more often than you think. If you pass this limit your connection stability will be penalized. Another reason is because a long cable is more difficult to examine for defects than a short one.
If needed, use a longer network cable to connect a device in the house. The network cable, (UTP – unshielded twisted pair), can go up to 100m (300 feet).
Some electric devices can interfere with the modem; avoid placing it near such devices.
Look at the modem’s lights. If the DSL light is off there is no service.
If there is no connection at all, (No DSL light), check the phone to see if you have a dial tone.
If the modem connects to a separate wall jack bring a phone and check if you ha
ve a dial tone, you might have a dial tone in the bedroom and not in the office.
Similarly check if there is TV service, if there is no TV service then most likely it is a bigger problem at your cable provider.
Look for the DSL filter as described above.
Check the LAN light on the modem. If the LAN LED is off your computer’s network adapter might be defective, or disabled, or the UTP cable that connects the computer with the modem might be defective. There is a chance that the modem’s LAN interface is defective.
If you have a solid DSL light, (check the modem’s manual, manufacturers have different signalling for established DSL connection), and you don’t have a connection check the password for the connection.
Step 4 – Connect to Your Modem’s Administration Interface
All of the modern modems have a WEB Administration Interface. The admin Interface is usually accessible via a WEB browser. It lets you configure the authentication and other diff
erent settings.
In order to administrate your modem you need the following:
The administrator’s password to access your router. If you don’t have it you can perform a hardware reset using the reset button located on the modem. You need to use a pin to press the button. This will reset all of your modem’s setting, including the admin pa
ssword, to the factory defaults.
The IP address of the router. If the modem has its DHCP server started, (by default yes), it will lease your computer an IP address and provide it with other IP configuration settings such as: “Default Gateway”,netmask, and DNS. The important part is the gateway’s IP address
as this is your modem’s internal interface and this is what you need to access your router’s web Interface. You can find all of this information by issuing the following command in a command prompt window with elevated rights, (admin credentials):
ipconfig /all
After issuing the command you will get a screen similar to this one. N
ote that the “Default Gateway” is the address of your modem.
In a web browser type: http://IPADDRESS where IPADDRES is your router.
For instance if your router’s (gateway) IP address is 192.168.200.1 the address you are looking for is: http://192.168.200.1.
Once connected to the web interface you need to enter the authentica
tion details. If you don’t have them you have to call your ISP which will make a reset after security verification.
If all of the previous steps did not solve the problem call your ISP. They might ask you to redo all of the steps above and maybe more. Be patient, they are just doing their job, they never assume, or they shouldn’t. The second they let themselves drawn into your speculation they make the same mistake as you do.
Step 5 – Correct the problems behind the modem
If the connection is OK the problem is behind the modem. This problem could be anything in your network.
Some suggestions are:
The router – many times the router can slow down your network. Try a reboot. If that doesn’t work try another model or another manufacturer. Do an upgrade of the firmware. Check the router’s configuration and try a default stripped down configuration.
The computer – most of the times, the slow performance over Internet is actually the poor performance of a computer.
