Start Guide. 

Make sure your Internet browser does not block pop-up windows and has JavaScript and Java 
enabled.

Make sure your computer is in the same subnet as the WRE2205. (If you know that there are 
routers between your computer and the WRE2205, skip this step.)

• If there is a DHCP server on your network, make sure your computer is using a dynamic IP 

address. 

• If there is no DHCP server on your network, make sure your computer’s IP address is in the 

same subnet as the WRE2205.

Reset the device to its factory defaults, and try to access the WRE2205 with the default IP address.

If the problem continues, contact the network administrator or vendor, or try one of the advanced 
suggestions.

• If your computer is connected wirelessly, use a computer that is connected to a LAN/ETHERNET 

port.
