• Try to access the ZyXEL Device using another service, such as Telnet. If you can access
the ZyXEL Device, check the remote management settings to find out why the ZyXEL
Device does not respond to HTTP.
• If your computer is connected to the WAN port or is connected wirelessly, use a computer
that is connected to a LAN/ETHERNET port.
• 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.
