Connecting to internet is so easy and everything is convenient.
But when you suddenly can't connect to the Internet, any of several things
could be wrong. You will feels like your face is against the wall and it is so frustrating. Please don’t panic and try to stay calm. Keep yourself together .
Use this checklist to find and solve common Internet connection problems :) :-
- Still in panic mode? Are You Overlooking the Obvious?
Unplugged or loose network cables are easy to miss yet one
of the most common reasons you might suddenly find yourself unable to connect
to the Internet. That's not a problem on wireless networks, but on most laptops
the Wi-Fi radio can be inadvertently shut off instead. On home networks, it's
also possible someone unplugged the router. So, the thing you should do is, ensure
your wired or wireless network hardware is switched on and plugged in.
- Feeling momentarily “blank”? Rule Out False Alarms
What may seem to be a network problem connecting to the
Internet is sometimes simply a Web site (or whatever server is on the other end
of the connection) being temporarily offline. Before assuming your Internet
connection is faulty, try visiting several popular Web sites rather than just
one.
- Are You Outside of Wireless Signal Range?
The performance of Wi-Fi network connections depends on
distance between the device and the wireless access point. The further away a
Wi-Fi device, the slower the local connection generally runs, until it breaks
altogether. Wireless signal interference in the area can also limit the
effective range of a Wi-Fi connection. Whenever you're unable to reach the
access point, you also can't connect to the Internet, obviously. So you can try
to use one of these options to measure the strength of your wireless signal and
try these ideas to expand the range of your Wi-Fi.
- Avoid I.P. Address Conflicts
In here, it’s getting a little bit “technical”. If your
computer and another on the network both have the same IP address, the conflict
between them will prevent either from working properly online. To resolve an IP
conflict, follow these instructions to release and renew your IP address. If
your network uses static IP addresses, manually change your IP to a different
number.
- Software could also cause this problems. Check for
Computer Firewall Malfunctions
Firewall software running on most computers is intended to
prevent unwanted network traffic from disrupting its operation. Unfortunately,
these software firewalls can malfunction and start blocking valid Internet
traffic. When two software firewalls, such as Windows Firewall plus a
third-party product, are installed on the same computer, contention between the
two can also incorrectly block traffic. In order to solve this, If you've
recently installed or upgraded software firewalls on your computer, temporarily
disable them to determine whether it may be the cause of Internet connection
problems.
- For hardcore user, try to deal with Computer Glitches
Computers, too, suffer from technical glitches. Although
relatively uncommon nowadays, a computer's network adapter hardware might
suddenly fail due to overheating or age. Failures in the operating system
software that control the adapter, on the other hand, can occur frequently
especially with computers that are heavily used. Viruses and worms also may
disable or block a computer's network interfaces from functioning properly.
Finally, if using a laptop or other mobile device, transporting it from one location
to another can corrupt the state of its network. It is good to check the
computer for malware and remove any found. On Windows computers, try resetting
the network connection. Reboot the computer if necessary.
- Are you sure about your Wi-Fi username and password? Has
Your Wireless Network Configuration Changed?
Wi-Fi networks with encryption options like WPA or WEP
turned on require computers to use matching security keys when connecting. If
someone changes the encryption keys or passphrase on the access point, devices
that worked before will suddenly be unable to establish sessions and Internet
connections. Likewise (though less likely), if the access point settings are
changed to require using a specific Wi-Fi channel number, some computers may be
unable to discover it. Before you jump to conclusion, confirm the Wi-Fi channel
number and encryption keys on your router have not recently changed (check with
the network administrator if necessary). When using a hotspot, follow the
provider's instructors for signing on carefully.
- Check for Broadband Router or Access Point Malfunctions
Home networks that use broadband routers are easier to
manage than those without one, but technical glitches with the router can also
prevent computers from connecting to the Internet. Router failures are caused
by overheating, excessive traffic, or simply an older unit going bad. Typical
symptoms of a flaky router include computers on the network not being able to
obtain IP addresses, or the router console not responding to requests.
Basically, you just need to check the router's lights and console if possible
to ensure it is running and responding properly. Troubleshoot and reset the
router if necessary.

- Nothings wrong with your part? Are You Being Blocked By
Your Service Provider?
Internet Service Providers (ISPs) can choose to block access
from your account if you fail to make payment or otherwise violate the
provider's Terms of Service. Especially when using paid hotspots that charge by
the hour or day, sometimes people forget to keep their subscription updated.
Other common reasons an ISP might block your account include exceeding
bandwidth caps, sending spam email, and downloading illegal or inappropriate
content. Try to contact your ISP if you suspect your account has been blocked.
- Last but not least, contact Your Internet Service
Provider
Sometimes, for those using satellite Internet service may
notice they can't connect to the Internet during periods of very bad weather.
Providers in dense urban areas (including cellular Internet carriers) sometimes
are unable to support peaks in network traffic that causes sporadic outages for
some customers. Finally, those who subscribe to newer or more complex forms of
Internet services (such as fixed wireless broadband) may experience more
downtime than others as providers encounter more issues with relatively less mature
equipment.
That's all for now, if things getting worse, please go get some help from technician or anybody who is qualified to solve the problems. Never let the pressure hold on to the situation or else, the problems will never end.
