Hi! I tried to access to my Zyxel p660hw d1 with the common 192.168.1.1. ip adress in internet explorer, but it doesn't seem to find the router log in page... Ho can i access to it then?

The dafault ip adresse is: 192.168.1.1

The dafault password is: 1234

Try this and let me know if it works

Are you sure this is the correct address??

If you have access to the internet, the normal way to access a home router would be this

Start
RUN
CMD

in the black window that pops up, type IPCONFIG /ALL

Look through the list for the active adapter, and then read the ip address that is listed as DEFAULT GATEWAY , this will be the address of your router (other than the 0.0.0.0 addresses) You may have more than one adapter, however the active one will have addresses next to them that arnt 0.0.0.0

try no password than admin than 1234

try typing 10.0.0.138 that should be the routers default connection

You can secure your wireless network wit WEP or WAP code.
For that Connect your router to computer with ethernet cable then you can access it with following default link.
http://192.168.0.1
or
http://192.168.1.1
For belkin router http://192.168.15.1
or
http://192.168.2.1

If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it.
Then it ask for user name and password.
Type user as "admin" and password as "admin" or "password" or blank.
Then you can see configuration page of router.
Click on wireless settings then enable WEP Security then add WEP code .It is your password to connect wi fi.Then save settings and restart router.
Then you can connect your wi fi network with that code.
Thanks for using FixYa.

try one of these
192.168.1.1
192.168.2.1

Since you are referring to a router you can access the configuration using the web configuration you just need to type the router default ip address on your browser to access the configuration.

the default ip address is 192.168.1.1

If you are connecting via usb you will need to install all software and drivers on your pc before plugging modem in. If you did install them already you may need to reinstall
If you connect through ethernet (RJ45 terminated network cable), you may have a firewall preventing regular acess to network.

solutions

1) restart pc and modem it may work just with this

2)USB only: reinstall all modem software, then restart all.

3)Ethernet only (network cable), |Restart all and disable firewall. If this does not work you may need to change network settings on your computer (fo example change IP from static to dynamic).

Its not your router you need to optimize. Its the computer!

I had an almost identical problem and contacted Tech support at Zyxel. They were excellent and the guy talked me through to a solution. The main issue related to 'Bandwith management' which defaults to active on the router configuration. Unset all three (Wan, Lan, Wlan) and see if it sorts out problem. Because of some other issues I did have to reset the router to start with and on the wireless client I unset 'Obtain IP address automatically' and used an IP address with the default gateway set to the router address. If this does not help, I would recommend talking to Zyxel Tech Support, the consultant I spoke to was brilliant.
