Tip & How-To about Computers & Internet

Basic Internet connection Troubleshooting

Test if your actually connected to the internet.

This assumes web pages fail. if not pingtest.net is one of many great sites to test connection speed.

Select 'Start' button
Select 'Run'
Type 'cmd'
Select 'Ok'
This opens a command window. Black with white text.
Type "ping 4.2.2.2" without quotes.
If you see "reply from" then you are connected but you may need to test DNS resolution.

DNS test:

Same command window.
Type "ping pingtest.net" without quotes

If you get a 'reply from' then you can resolve DNS.

If any of these ping test fail start with resetting your connection, see ipconfig /renew and/or ipconfig /flushdns then reviewing your connections and possibly contact your ISP.

Doing a Repair on XP - Vista - Windows 7 does the same (but more) as ipconfig.

I will help you to know what is Ping!!!!
Ping is a basic Internet program that allows a user to verify that a particular IP address exists and can accept requests.

Ping is used diagnostically to ensure that a host computer the user is trying to reach is actually operating. Ping works by sending an Internet Control Message Protocol (ICMP) Echo Request to a specified interface on the network and waiting for a reply. Ping can be used for troubleshooting to test connectivity and determine response time.

As a verb, ping means "to get the attention of" or "to check for the presence of" another party online. The computer acronym (for Packet Internet or Inter-Network Groper) was contrived
to match the submariners' term for the sound of a returned sonar pulse.

Tip: To find out the dot address (such as 205.245.172.72) for a given domain name, Windows users can go to their command prompt screen (start/run/cmd) and enter ping xxxxx.yyy (where xxxxx is the second-level domain name like "whatis" and yyy is the top-level domain name like "com").


You can check the ping test in http://pingtest.net/ also you can check that here www.whoisxy.com

slow buffering of videos


Which web-site are you viewing?
How fast is your Internet connection?
Is it a cable-modem or a DSL-modem?
Ask your ISP what speed you are paying for, e.g., 1 Mbit/second, or 5 Mbit/second, or 25 Mbit/second?
Ask your ISP if they have a "speed-test" web-site, e.g., http://SpeedTest.Shaw.ca
that can measure your actual speed. Run it, and compare your "advertised" speed
versus your "actual" speed.

internet connot display web page all the time , and slow download speeds,modem adsl light coming on constantly.


Dealt with a lot of these. It is either :

1. Wrong password and ISP information - double check that everything your ISP has asked you to put in is correct

2. Bad phone connection - even if the ADSL light comes on (which means the router can see an ADSL connection from your phone provider) does not mean the line is clean. Pull out all the connections to your home phone, and just plug in the router to get it all up and running. Once happy reconnect one at a time all phones, digi boxes etc.

3. Adding to 2. - have you got a splitter? If so, change your splitter or reconnect, splitters can fail quite easily and get old fast - a bad splitter creates a lot of noise on the line, making the internet time out

It could be a router fault, they last about 4 years before they start doing silly things. But likely one of the above.

Try two sites once you are happy :

www.speedtest.net - to check your connection speed
www.pingtest.net - to check line quality
