Wired Network

wired network is a common type of wired configuration. Most wired networks use Ethernet cables to transfer data between connected PCs. In a small wired network, a single router may be used to connect all the computers. Largernetworks often involve multiple routers or switches that connect to each other.

Wireless Network

Wireless network is a network set up by using radio signal frequency to communicate among computers and othernetwork devices. Sometimes it’s also referred to as WiFinetwork or WLAN. This network is getting popular nowadays due to easy to setup feature and no cabling involved.

Wired & Wireless Network Installation & Trouble Shooting

wireless network allows devices to stay connected to the network but roam untethered to any wires. Access points amplify Wi-Fi signals, so a device can be far from a router but still be connected to the network. A wired network has some disadvantages when compared to a wireless network.

Many network connection issues are caused byproblems with the cables or firewall settings. Use the following checklist to solve these problems with home networks: Check all of the network cables and wires. A loose or disconnected cable or wireprevents a network connection and Internet access.

At times, your networks either wired or wireless will always be subject to some problems, failures and faults. In most of the cases, the problems that tend to arise or occur are not so much sophisticated and you can be easily troubleshoot them as long as you are conversant with all the network troubleshooting tools. You should also be equipped with the knowledge to help you identify a network problem so as to be in a position to establish the most ideal way to troubleshoot it. In some instances, some specific steps have to be followed in the course of troubleshooting. It is therefore important that you are also familiar with these steps so as to make your troubleshooting activity quite easy. Discussed below are some common network symptoms that can call for network troubleshooting.

Common symptoms

Here are some common symptoms of the problems which arise when the connection is made;


No connectivity

At times, the local devices we use tend to have no connectivity to a particular network or rather the internet. This can be very agonizing since it is a clear indication that your computer is not communicating with other network devices.

This is a problem that could be caused by many factors. However, the first step towards determining the absence of connectivity is through pinging. If your computer fails to ping, then it is outright that there is some problem. Try to take a look at the adapter configurations in the computer. Plug in the network cable. This problem can also result due to incorrect configuration of the device to a particular subnet mask. To establish if your device is connected to the internet, you should try pinging the Google DNS server and if connected, it gives a response to the ping.

APIPA address

Automatic private IP addresses are addresses that are automatically assigned by your operating system when the DHCP server is unavailable. These are addresses that are designed to work on local links or subnets. To determine the available IP configurations in your network, you can use the IPCONFIG command.

Limited connectivity

Limited connectivity is not quite a serious problem as it basically means that your device has access to some connection but not fully. This problem can be easily resolved by checking the connection’s bandwidth or checking the network adapters for problems that could be resulting into such an issue. You should also ensure that there is no network interference.

Local connectivity

Local connectivity is at times lost as a result of poor subnet configurations. In such a case, your device is not able to communicate with other devices on the same local network due to some mismatch in the subnets.

Intermittent connectivity

An intermittent connectivity is a network problem that mainly comes as a result of having duplicate IP addresses on a particular network. By having duplicate Ip addresses it means that the devices have exactly the same IP addresses and therefore it may lead to a situation where some devices can barely communicate with each other. Such a problem causes devices to appear as if they are communicating with some device and not others. This problem can be easily solved by making sure that there are no duplicate IP addresses on the network maybe by removing one of the devices, making IP address reconfigurations and making sure that all network users have a unique IP address.

IP conflict

An Ip conflict in a network is mainly as a result of the existence of duplicate ip addresses. In spite of this being a bad networking problem, the operating system has the capability of detecting duplicate IP addresses. An IP conflict can result into the absence of communication between subnets configured in different machines.

Slow transfer speeds

This is a problem that many network users tend to refer to as slow networks. Handling this problem can be quite challenging owing to the fact that it can be experienced in many different places. In this case, you may require to bring down the problem into pieces so as to easily identify the availability and health of your network.

Such a problem can arise due to very many reasons which can be quite difficult to establish. You can decide to manually set your network speed so that it remains constant throughout and hence no instances of slowing down. The networking hardware can also be the cause of such a problem and therefore checking the network adapter can be of much help. You should also take a look at the networking cables.

Low RF signal

Low radio frequency signal is a challenge that is mainly witnessed in wireless networks. In this case, network interference becomes highly sensitive such as conflicting frequencies due to an activated access point. Such a problem can also be induced by the presence of some other signal emitting devices such as a microwave.

In cases where there are numerous access points, you should ensure that the frequencies do not overlap so as to reduce the chances of interference.

CCTV Camera Installation and Trouble Shooting

10 Common CCTV Problems and How to Fix Them

It can be hard understanding the problems that occur with your CCTV, which is why our friendly team have put together a guide to help you to fix the issues.

1. Verify camera power and connection

Sometimes a problem can be as simple as a disconnected lead and it might even be that the network is currently down. Internet protocol (IP) cameras generally have LED indicators that are used for transmitting data across to the network but this might be hidden inside the camera.

If the LEDs on the camera are not lighting up, you should check to see if the camera is powered externally (plugged into the wall). Should your camera be powered via electricity and not battery, you will want to check that the camera is receiving the appropriate wattage as a complicated camera such as a pan-tilt-zoom, will require more watts that a normal plug will supply.

2. Discover and ping camera

Find out your camera’s IP address by checking the camera’s directory. Once you find your address you will be able to ‘ping’ it using your laptop or smartphone to test the strength of the connection.

Type ‘cmd’ into windows search engine and this should open a DOS command prompt. When this pops up, you will be asked to type in ‘ping’ and your IP address.

You may see either ‘Request Time Out’ or ‘Destination Host Unreachable’ appear on the screen. If it does, check to see if the device you are using is on the same network as your camera. If you do see the camera on the network, attempt to connect using your browser.

3. Know username / password

If you can ping the camera but find yourself unable to connect then it’s possible that you have typed in the wrong login or password. If this is the cause, you will want to refer to the manual.

4. Check ARP tables

Check Address Resolution Protocol (ARP) tables, usually located on the outside of the camera. It is possible to cross reference MAC and IP addresses using the ARP.

5. Confirm no IP conflict

If you have more than one camera you need to make sure that they have different IP addresses as this can stop you from accessing one or all cameras.

6. Upgrade firmware

See to it that your camera is up to date. You can do this by connecting to VMS and accessing the camera’s web page.

7. Reboot camera

Sometimes it’s the first thing we do – turn the system off for 10-20 seconds and input your settings again.

8. Check cabling

Make sure that the cables are straight and firmly intact, because if there are knots or loose cables this could be the root of your problem.

9. Factory reset camera

This can be a drastic thing to do as you can lose all of your history but this process will help to troubleshoot any issues. A factory reset can be done simply by pushing a paperclip into the pinhole reset button located at the back.

10. Call manufacturer or remote monitoring provider for support

If you’re ever unsure, seek help from an expert who can help you every step of the way.
