APPENDIX A – POSSIBLE PROBLEMS AND OPTIONS FOR THEIR SOLUTION 

Problem 

Possible Cause 

Solution 

Entering router's IP 
address (e.g. 192.168.1.1) 
could not  access to the 
web interface 

The PC does not belong to 
the IP subnetwork for 
connection to the web 
interface 

Set the address from the 192.168.1.0/24 subnet in 
the Internet connection options of your computer 

 

Defective cable 

Check the physical connection by checking of the 
indicator status (all LEDs should be on). When the 
LEDs are off, use another cable or connect to 
another port of the device if it is possible. If your 
computer is switched off, LEDs may also be off. 

 

Access denied by your 
firewall 

Disable firewall on your computer 

Forgotten/incorrect 
password to the web 
interface of the device 

_________ 

Reset the router to default settings by using the F 
button on the rear panel. Unfortunately, all made 
settings will be lost in this case.
