PROBLEM CORRECTIVE ACTION
I cannot access
the web
configurator.
Refer to the Quick Start Guide for hardware connections.
Check that you have enabled web service access. If you have configured a secured
client IP address, your computer’s IP address must match it. Refer to the chapter on
remote management for details.
For WAN access, you must configure remote management to allow server access
from the Wan (or all). Refer to the chapters on remote management for details.
Your computer’s and the ZyXEL Device’s IP addresses must be on the same subnet
for LAN access.
If you changed the ZyXEL Device’s LAN IP address, then enter the new one as the
URL.
See also Section 13.8 on page 114.
See the following section to check that pop-up windows, JavaScripts and Java
permissions are allowed.
You may also need to clear your Internet browser’s cache.
In Internet Explorer, click Tools and then Internet Options to open the Internet
Options screen.
In the General tab, click Delete Files. In the pop-up window, select the Delete all
offline content check box and click OK. Click OK in the Internet Options screen to
close it.
If you disconnect your computer from one device and connect it to another device
that has the same IP address, your computer’s ARP (Address Resolution Protocol)
table may contain an entry that maps the management IP address to the previous
device’s MAC address).
In Windows, use arp -d at the command prompt to delete all entries in your
computer’s ARP table.
