Simple Internet Troubleshooting

Posted on by

I was with one customer regarding his internet not working. Well maybe I can write out a simple troubleshooting guide that I use to troubleshoot the Internet issue.

First of all make sure all the physical connection like cables are connected properly from PC to router/modem or switch. This is important as I had case where they said is Internet not working turn out that the network cable behind the PC got drop out. So physically check the network connection is important.

Next try to determine your own ip address, the way I is to open up a command promt and key in “ipconfig /all” which will show quite a lot of information on your system. Like this screen below
ipconfig-all

It tell you that your own IP address is 10.1.1.103 and the gateway is 10.1.1.1
From here, we can try to do a ping on your own IP address to make sure that you can ping via
 ping 10.1.1.103
if the result show reply from 10.1.1.130: xxxx xxxx xxxx
that means that we are communicating with ourself then next we can further verified if we can talk to the gateway which is also the router via

ping 10.1.1.1
if the result show reply from 10.1.1.1: xxxx xxxx xxxx

that means that we know that we can talk to the router. Then we can try pinging further like 8.8.8.8 which is the Google DNS server via

ping 8.8.8.8

if the result show reply from 8.8.8.8: xxxx xxxx xxxx

then we should be able to connect to the internet.

If result show time out or destination host unreachable. We then can conclude we have problem it some stages depend on which ping stages fail. We can isolate out the problem and concentrate on what cause it and solve it. Being network card fail or cable  has problem or router faulty all are easily determine via a simple ping test.

How to know if is a scam or spam mail

Posted on by

Got one of my customer who ask me this question, how do we know if this mail is a fake mail or spam mail etc. Simple first look at the sender to see if is someone you know. Then examine his email to see if is tally with the secender.

Example if the sender is from john smith and the email address is 06alpha21@xxxx.com then this look suspecting. you can then send a real message to John Smith and check with him that did he send you this mail with the following content etc.

Another case will be if is coming from a courier services check also the email address as it could be something else. or make a phone call to the courier service to enquire regarding this parcel etc.

There is one case that your friend mail could be hack and sending from him to you. but those mail could easily find with fault if you look at the detail.

I had a mail from “paypal” saying that i had make purchase to a site of 149.99 dollars and the mail look real, after a few detail examine on the mail i realize that the problem is that email account that “paypel” send me was wrong and i never use that mail to register with paypel.

So a if you are careful before you click the mail it could save you from getting a tech to come and help.
