Wireless router dropping then disappeared

I connected my windows laptop to the wireless network, it worked ok, but kept dropping the signal, even when i moved to right beside the router. I connected my mac and the wireless signals works fine but the laptop will not connect wirelessly at all. It works fine when wired. Firewall settings are low.

SolutionLog onto the web-based admin tool of the router. Click on Tools at the top, then Misc. on the left menu..
set the following:

UPNP Settings = Disabled
Gaming Mode = Disabled
PPTP = Disabled
IPSec = Disabled 
On the computer where the connection is being lost.. go to your network connections, right-click on the wireless connection and view its properties. Under the authentication tab, you should see a check-box option for Enable IEEE 802.1x authentication for this network - UNCHECK IT!! 


Change the Super G mode setting of the router to Super G without Turbo. By doing this, the connection will be stable.

My Westell modem was just replaced by a GT704WG. I've had wireless connections all week when working at my desk where the router is - less than 6 inches away. I just realized that since I moved the router several FEET away the wirless connection is now fine. I don't understand this, but it was a simple fix.

I don't know a solution but the router will appear in the list along with neighboring routers but it will disappear and the others will still be there so it's not an adapter problem something in the router stops sending a signal

If other wireless hosts are connecting to the wireless router with no problem, and the windows laptop intermittently connects, then this seems to indicate a problem with the wireless card in your windows laptop. If the device is still under warranty, it should not be a problem to contact the laptop vendor and have it replaced.

SOURCE: zyxel p660hw and g202 problem

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.

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!

SOURCE: connecting using wireless

I don't believe Zyxel supports only Zyxel products. Finally, after analyzing the problem between the zyxel and the router, I found a solution that worked and allowed me to network both wired and wireless connections here at home. Set your router to auto-dhcp settings. Clone the MAC address of your computer. After this is done, put OFF first the router but make sure that the cable from the router WAN port is attached to the modem already. Then, put ON the zyxel and wait until it is fully functioning (2 lighted LED lights) before you switch ON the modem. Let both units (router and zyxel modem)synchronize first about a minute or so. Then connect/put ON your computers.

I found the above procedure to do it step by step so as to avoid conflict signals during synchronization which seems to be causing the non-internet connection.

Hope this helps!
