Networkcables are the most important part of the Internet. A cabled network can
provide high speed connection with fewer chances of failure. Errors like
address not found, timed out connections, browser cannot display this webpage, and
a little red X in the network connection icon etc indicate that some problems
are there with the Internet connection. The main reasons behind connection
problems are cables that are not connected properly, network connection setting
issues, software or hardware problems, corrupted drivers, missing updates etc.
Problems in cable configuration:
The selection of the cable should be
decided based on the current and future needs and based on the budget. Usage of
wrong cables can defeat the internet connection efforts. For directly
connecting two computers cross-over cables should be used and if connecting
devices with hub or router straight-through cables should be used.
Troubleshooting network configuration may depend on the operating system,
connection type and other factors. If there is any problem with the internet
connection, the computers network icon might display a red X or other error
message. If all seems to be working well, but network can’t be accessed then
the problem may be with the Internet Service Provider (ISP).
Power Cycling:
Power
cycling is a simple approach in which modem is just turned off, waiting for a
few seconds and then turning it on again. If it doesn’t work, the same steps
can be done more elaborately, by turning off every device in the network and
then power on them in a particular order. Shut down the computer, unplug the
power cords of the modem, router, hub and access point. While turning on, power
on the modem first, and then router or hub, turn on the computer last. While
turning on each device allow the devices to complete its boot-up sequence
before turning on the next device.
Ordering
the wire according to the correct wiring scheme is very important. Eight wires
are divided in to four twisted pairs. Double check the wiring order, because
once a plug has been crimped on to cable, it then can’t be removed and reused.
It’s
the easiest troubleshooting method in which all the cables and connections
involved in the internet connection are checked. It’s not a time consuming
process to make sure that nothing has changed. Start from where the cable
connection starts in the building, check whether all the connections are
secure, and not damaged by birds, bugs, or squirrels. If there is a router,
check whether the cables are going to the correct point. There are three steps
in wire checking:
- Check the cable that runs from wall to the cable modem.
- Check the Ethernet cable that runs from modem to the computer.
- Check whether the modem is connected to power supply and power to the modem is turned on.
Driver update problems:
Drivers which are incompatible,
outdated or corrupted can cause network disconnections. Drivers become
corrupted when there is an upgrade in the operating system, when had recent
power outages, viruses or other computer problems. The problems can be resolved
by downloading and installing the latest network adapter driver.
Router update problem:
The
router or network adapter may need a firmware upgrade, when it’s only able to
connect using WEP security or no security. Firmware is the embedded software in
any hardware device which controls how the device should interact with the
operating system. If this problem occurs, download the firmware upgrade from
the manufacturer’s website and install it according to the instructions given.
Problems with electrical interference:
Electrical
equipments can cause interference and can slow down the internet connection.
Keep the router/modem away from electrical gadgets and keep experiments with
turning off devices.
