Computer Communication Problems

Basic: Of the computers connected to the same network, some can 

communicate and some cannot.

Possible Cause

Suggested Solution(s)

The setup of the wireless 

computer in the Ad-Hoc 

mode is incorrect.

1. Record the wireless settings (SSID, 

authentication encryption setting, and channel) 

and the network settings (IP address, subnet 

mask and default gateway) of the computer 

that cannot communicate. 

2. Compare them to the equivalent settings for a 

wireless computer that can communicate.

3. Change the settings for the 

non-communicating computer to match those 

of the communicating computer.

The wired network setup of 

the computer in the 

Infrastructure mode is 

incorrect.

1. Check the difference between the network 

settings (IP address, subnet mask and default 

gateway) of the computer that cannot 

communicate and the settings of the computer 

that can communicate.

2. Change the nework settings of the 

non-communicating computer to match those 

of the communicating computer.

There is a failure in the LAN 

cable or hub connecting to 

the computer in the 

Infrastructure mode.

Check the LAN cable and hub connected to the 

computer that cannot communicate. Replace 

them if necessary.

The 'IP Filtering' setting of 

the printer is incorrect.

Change the printer’s 'IP Filtering' setting to enable 

connection.

Note: You must change the  'IP Filtering' setting 

for the wired LAN interface and the wireless LAN 

card separately.
