Custom Computer Consulting Wired Network Installation

Troubleshooting LAN & WLAN Networks

Having trouble with your network. No longer able to connect to the internet or any other computer and/or device. Does the performance seem to be sluggish and degraded. Custom Computer Consulting can diagnose, identify and improve your network performance. Or do simply need up to improve your network. If needed Custom Computer Consulting can diagnose, identify, and repair wireless installation.

CCC - Wired Standard Check List

	Isolate Problem - What is functioning and what is NOT
	Device Configuration - Check configurations on all devices within the network to assure they are properly configured.
	Check for Conflicting IP addresses - Improperly assignment of IP Address
	Network Hardware Integrity - (EIC, Hub, Switch, Router, modem, etc.)
	Network Collisions - This result in slow connectivity. It can occur as result of bad network setup plan involving the installation of the wire, to where it was placed.
	Crosstalk (referred to as NOISE). A leakage from other connection (cochineal interference) or related to (adjacent - channel interference.
	Software - Improper configuration, in the DNS WINS, the register, and etc
	Signal Attenuation (decrease in signals amplitude), Signals is stronger then becomes faint. Several factors could effect signal attention. Length of cable
	Cable Problems - cable cut, shorted, Incorrectly wired, cable connection, interference or connector problem.

Common Problems (that occur in cabling)

Crosstalk (referred to as NOISE): A leakage from other connections (cochineal interference) or related to (adjacent – channel interference.

Signal Attenuation (decrease in signal amplitude): Signal is stronger then becomes faint whisper. Several factors create attenuation

Cable Problems: Cable cut or shorted, incorrectly wired cable, cable connection, interference level, or connector problem.

Connectivity Problems: When one or more devices in a network improperly configured or malfunction of a component, such as hub, a router, or a switch.

Network Collisions: These often lead to slow connectivity. This problem can occur as a result of bad network setup/plan.

Software Problem: Often times, network problems can be a result of software configuration such as DNS configuration, WINS configure, the registry, etc.

Duplicate IP Addressing: Is a common problem in many network environments. This occurs when two devices try to use the same IP address. This can result in intermittent commutations.

CCC - Wireless Standard Check List

	Security Level - Improper authentication (wrong pin# or passkey phrase entered incorrectly or an unsupported security measures.
	Electrical Interference - interference from competing devices, such as cordless phones, baby monitors, alarm systems, and microwave ovens.
	Signal Attenuation - Location (area the wireless is located) and what may be interfering with the signal.
	Power Output - Cochineal interface where the signal on the same channel overlap one another
	Cross Channel Interface - Improper selection of channel or incorrect band selection based on your surroundings.
	Antenna Positions - Is the antenna clear from any form of obstruction. Wireless signal radiates downward
	Firmware - The program code stored in a non-volatile memory device such as a ROM, EPROM, or flash memory. Manufacturing are always updating and correcting the code.
	Type of Antenna - Is it an omni or direction type antenna will effect how the signal is received and transmitted to the device. Omni directional are good for higher areas while Directional antennas aimed at the flower level help create a cone coverage when area obstruction surrounds the upper area
	Signal Blockage - Building materials have an effect on the wireless signals attenuation (loss or reduction). Material such as glass (2b), wood (3db), cubicle (3db-5db), plasterboard wall (3db), dry wall(4b), cinder block (5db), marble (5db), glass wall with metal frame (6db), brick wall (8db), and concrete wall (10db-15db). All will degrade the signal.
	Improper Setup - Setup perimeters related to the proper configuration of your wireless device.

CCC - Service Time
Unfortunately, it is harder to put an exit service time as it depends on relates to the implantation of a network. It It will depend on the complexity and the purposed network
