ZyXEL NMP-1100W wireless network goes down

The problem has more to do with your Internet Service Provider than your router. The more users online within your neighborhood the less bandwidth or signal strength you'll receive. For instance around noon each day is one of the busy times for Internet use everywhere. It also, depends and what's occurring amongst the users within the house. Downloading, streaming music or videos is very taxing to bandwidth especially if five users are trying to stream video at the same time. Perhaps you may need to increase your service speed. So if you have 3M service you may wish to move up to 5M,10M or 15M service.

I suspect the issue is not the firmware- check the security settings you have for your wireless network. If you are using Windows Vista/7, it would be through Network > Network and Sharing Center > Manage Wireless Connections > right click on the appropriate connection, go to properties and look for security. Check with a wired pc what the settings are in your Zyxel- match, and you should be able to connect wirelessly

If the router is 3 or more years old, it's possible it is failing. In all the years I've been online I have gone thru 3 routers.

I'm NOT a Windows guru, but I think this is an issue with Windows, not your Zyxel driver.
There is a setting somewhere in the network area of Windows that tells it to automatically connect to a known favorite network if that network appears. I suspect you just have to find that setting, turn it on, and make sure the network you use is in your list of favorites.

Go to the router configuration and change the options so you could use both of them, there is an option says only one type of connection or both of them, change it to both, and everything will be fine.

It is not compatible at all wifi is a wireless connection and you are adding another device called zyxel it is like i have adsl unlimited and am adding a new connection with adsl normal of course it will go down not same speed at all wifi connection is 54 mbps normal speed where as zyxel is too slow with only 10 mbps

I to am having the same problem

the wireless adapter needs to connect to a wireless router which then connects to the internet.
it's the router that is connected to the internet and shares it in your home network.

I can tell that your network topology is not the most complicated ever.So u ve got 3 terminals,1 desktop pc and 2 laptop.Simple,reset your zyxel(from the button on the back) and reconfigure the Local area interface connection(ip & subnet mask for the zyxel),reconfigure your internet connection,(WAN zyxel interface) in case the zyxel is your Internet gateway too.Third,make sure NAT & Firewall are up and running(usually are by default) Finally,reconfigure the WiFi interface with the correct SSID name & WEP key or whatever security you prefer.Write down the security pass for your wireless and you are done.Good Luck.

because of zyxel support only zyxel product only
