I can see the 

Login

 screen, but I cannot log in to the ES-305.

1

Make sure you have entered the user name and password correctly. These fields are case-
sensitive, so make sure [Caps Lock] is not on. The ES-305 has no user name or password 
by default, so try just clicking 

OK

 when you are asked for your login information.

2

You cannot log in to the web configurator while someone is using the web configurator 
or Telnet to access the ES-305. Log out of the ES-305 in the other session, or ask the 
person who is logged in to log out. 

3

Disconnect and re-connect the power adaptor or cord to the ES-305. 

4

If this does not work, you have to reset the device to its factory defaults. See 

Section 6.4 

on page 64

.

1

Check the hardware connections, and make sure the LEDs are behaving as expected. See 
the Quick Start Guide and 

Section 1.4 on page 22

. 

2

Ensure that any information you entered in the 

Network Settings

 screen (such as an IP 

address) is correct. If you changed the default VLAN settings, ensure that they are 
properly configured, or return them to the default configuration (see 

Section 6.4 on page 

64

 for how to reset the ES-305).

3

Disconnect all the cables from your device, and follow the directions in the Quick Start 
Guide again. 

4

If the problem continues, contact your ISP.
