I need to know how to create a user name and password for access to router. I have never needed to use this feature but I am renting my apartment and just want to lock it down to prevent unauthorised access. Its not that the people renting are crooks....far from it but as they need WiFi and in each room there are 4 Cat5e access points I just want to be prudent.

I am sure there are instructions on how to set up a "Guest Wifi account" but I cant find them anywhere...any ideas?

I also would like to set up the 'remote access" feature so I can log in from Spain to make sure all is OK.
What would be the simplest set up?
Looking at the "System Maintenance - Management" page it shows ...

Management Access Control
Allow management from the Internet
FTP Server
HTTP Server
HTTPS Server
Telnet Server
SSH Server
and so on.
Are there any clear instructions on the set up for this. I will be connecting from a windows7 Acer from using on of those high speed dongles.
Many thanks,

For password
system maintenance> Administrator Password Setup
one more feature i have not use it
System maintenance>user password

Don't know how to block lan access but for wifi guest , i think you need to enable SSID 2,3 or 4 here
Wireless LAN >> General Setup

or do a search about it how to separate guest from lan...example

for remote access that is the correct one
once you enable type your ip address to any browser and will give you access to your router
