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!

Can you try the laptop somewhere else? Try Mcdonalds or Starbucks, work, school, etc. Does it see the connection there? Does it connect ok there. Break your troubleshooting it into small steps. If it works else where then something is set wrong in your wireless at home. If it doesn't work else where then keep troubleshooting the laptop itself. When your watching the SSID show up then disappear are all wireless SSID also doing the same. Can you see neighbor and just watch if they drop in and out? Can you confirm your router is the same network speed. B,G or N. Make sure its a on a speed the laptop can do. Can you change your router and disable the security for a little while and see if that effects how the laptop connects. IF it works without security then check your security settings, Maybe the router is set to an old or newer type if security, Try different one's if it works correctly with security off. Can you login into your router and look at the logs its recording. Maybe there's a clue in it. Re-confirm the gateway and subnet are correct. I don't know if your XP, vista or 7, but open a command window or Dos prompt and type "ipconfig /a" It will list all the network information. Also type "ipconfig ?" For a list of options to use with the command. You may need to a release or renew the connection.

1.Log into router. Using either to in a browser window that is ( internet Explorer or Firefox).
2. Verify wireless router name( on the computer) >>> ( on/off) ( router status window)
3.Note router name you are connecting to.
4.. Check the laptop do ipconfig /all to see current IP addresses.
5. Set the laptop up in the router by WEP KEY or MAC address. This set up in the "security tab" in the router. using or to access through a browser.
6.Note router name you are connecting to.
7. Move the laptop/desktop about 20ft away and try to log on to the internet.
This is for all routers to set up wirelessly.
8. check for firmware update at the manufacturers site for your model router and the gaming site for the proper ports for play.
You may just have lost connectivity with the server. Check your QOS ( Quality of Service ) in the router settings to assure your wireless connectivity. Wireless gaming console are notorious for dropping connection. You also need to improve your antenna range.

Try resetting your wireless router first, then make sure that the network you are connecting to is yours and not another nearby wireless signal (I live in an area that's polluted with wireless signals and sometimes a neighbor's signal will be stronger than mine, so it will try to connect to theirs). If that doesn't work then go to your Network and Sharing Center and choose the setup a network connection option. You'll have to manually enter your info again but it should work fine.

Wireless router dropping then disappeared

There are two possible generic reasons I have found in reviewing internet posts.

One claims there may be a windows issue with hiding the SSID (or router name) and enabling WEP or WPA secure/encrypted wireless connections and random disconnections of service to the wireless adapter. The recommended solution is not to hide the SSID (or router name) and maintain the WEP or WPA secure/encrypted service.

Another claims that there may be an "overload" of requirements on a specific wireless channel in your area (sometimes by non routers such as wireless phones). Many routers default to channel 6. I you have a wireless monitor on a PC that shows routers and their channel assignments nearby -- if everyone is on channel 6 you may want to move to channel 1 or 11 and see if your device works better. There are some wireless routers with capability for 108mbs transmission rates that actually transmit on two channels at once that could be affecting your response so if channel 1 does not work try channel 11 or vice versa.

Disconnects while working.

it may be as simple as the wireless connection signal strength, as doors, solid walls or any solid object that is in it's line will cause the signal to be very low, and at that point it will disconect from the internet as it is unable to send packets of information to your wireless card from the router. You can try your router in another telephone point that is nearer the pc to see if the connection drops, or use a different channel number which can be changed in the routers settings and the wireless cards properties as interference from other electrical appliances on the MHZ level can cause signal loss. Laptops tend to suffer less with the signal loss because they normally have a signal booster in the screen of the laptop within the wireless receiver ariel.
