Zyxel 660HW-D1 drops wireless connection to second and third comp

SOURCE: Zyxel Modem Router P660hw wont work on LAN

If a LAN connected PC will not work while a wireless laptop is connected you need to go into advanced router setup, bandwidth management, and untick the three boxes labeled "active" to disable the band width management. Easy!

Hi Friend,
Before Connecting your internet we must check in ur system.

1.Go to Start---->Run------>type cmd----->in the black screen type ping 127.0.0.1
2.check wither its getting reply or request
3.If u are getting reply then ur system is perfect i.e., your NIC Card is installed properly.
4.check wither any proxy is enabled in the LAN settings.
go to browser--->tools---->internet options(Options)----->Connection--->Lan Setting--->there should noy be any tick mark in the boxes

Now we can check the connectivity,
1.Connect the PC from the Router Lan Port and the modem connectivity to the Wan Port of the Router.
2.Assign the Ip address as obtain ip address automatically

Right click networkplaces--->properties--->Lan Connection Properties---->double click the internet protocol(Tcp/IP).In the next box u must select the Obtain Ip address automatically

3.Now u switch on the modem after 30 sec switch on the Router.
4. Launch your web browser.
5 Type "192.168.1.1" as the URL.
6For administrator access enter the default admin password 1234 to configure the wizards
and the advanced features.
7 Click Login to proceed to a screen asking you to change your password or click Cancel
to revert to the default password.
8 If you entered the admin password, it is highly recommended you change the default
admin password! Enter a new password between 1 and 30 characters, retype it to
9.Then u can configure the ip address

It could be caused by interference by other nearby networks/devices. Try changing the wireless channel.

You will have to reset the router to factory settings. There is a small hole in the back, depress the microswitch with a paper clip when the power is on. The default password is 1234. Some of these devices are general, while others are hardwired to work with certain providers. So if, say, this 660 is branded with embarq it is unlikely that you can set the parameters to work with other providers.

I should mention that if you care about security you should not use WEP - a cracker can break an internet connected WEP device in minutes with the right toolset. The protocol has many problems that simply can't be fixed, period. Consider using WPA2 with WPA backcompatability, as allowed by the 660.
