A down, slow, or unreliable
network can lead to significant downtime and frustration. Here, we’ll help you
troubleshoot a few of the most common network problems.
Try
The Power Cycle
When it comes to the physical network,
there are two devices that can possibly fail: the router and the modem. Both have simple fixes. Turn them
off, wait ten seconds or so, and turn them back on again. This “power cycling”
will resolve many network issues. For
example, the router may have had a problem
renewing its IP address or releasing new IP addresses for the computers on your
network. Restarting the router or modem resets the
device’s software, often solving these sorts of problems.
Examine
Your Network Adapter
If that didn’t solve the issue, check the
PC’s network adapter. The Network Diagnostic utility built into Windows 7 can
renew your computer’s IP address and ensure that the network adapter is
enabled. To run Network Diagnostic in Windows 7, click the Start orb, select
Control Panel, choose Network And Internet, and select Network And Sharing
Center. Under View Your Active Networks, select the link next to Connections
and click the Diagnose button. Windows will run a few tests to try and fix the
problem.
Weak
Wireless Signal
Watch out for nearby devices such as
microwaves, Bluetooth devices, and phones, all of which can cause interference
in the signal. Move your router someplace where it’s less likely to experience interference.
Intermittent
Connection
You’ll
want to check the physical connections to your router to see if all the cords
are securely connected. A loose connection may explain why the Web drops
intermittently. It’s possible that the cable may have a cut or kink that causes
a fault in the connection. Try replacing the Ethernet cable.
