    Hello,

    Every time my wireless drops out, I need to restart windows and click the "Turn wireless on" button in windows mobility centre before it will reconnect. Usually it is after i get a "Limited connectivity" error message.

    I'm using a Fujitsu Lifebook T Series Tablet running Windows Vista (Business).
    I have recently changed to a Netgear "RangeMax" Dual Band Wireless-N Gigabit Router (however I'm *pretty* sure this didnt start happening until a month after I started using it)

    When I open windows mobility centre after the wireless drops out, the caption on the wireless button is still "Turn wireless off", and clicking on it does nothing. Its not until i restart windows that the caption changes to "Turn wireless on" and I can get wireless working again. When I do click on it, the caption changes as expected.

    Do you have any ideas on why my wireless does not reconnect after it drops and how i can fix it? Failing that, is there any way that I can turn wireless back on without using Windows mobility centre, or fix windows mobility centre so that the button allows me to turn wireless back on.

    Please let me know what further information would help and also whether or not i have posted it in the right section (I assumed it's a software issue as windows mobility center doesnt update).

    Thanks a lot.

    Hey thickdude,

    How about if the Windows Vista machine connects to the router through a wired connection? Can you connect?

    Cheers,

    And you mean that the wireless turns off, as if you had switched it off? Not just disconnected from the network, but actually turned off? But the software thinks that it is still on but won't turn it off?

    When this happens does the wireless adapter still appear in Device Manager?

    Thanks for the quick replies Kim and Terry.

    Yes, so once my wireless drops out, I can plug in an ethernet cable and establish a network connection without rebooting or doing anything else, it's just the wireless connection that won't reconnect.

    The problem happens when it drops out on its own accord and I get a message saying limited connectivity, it's not from manually turning it off. When I reboot however, I have to then open windows mobility centre and use "Turn wireless on". So it seems as if wireless has been turned off however the button caption in windows mobility centre does not update until after I reboot.

    If I use the hardware switch to turn wireless (and bluetooth) off and turn it back on again it has no affect, except that the icon in the status bar changes from limited connectivity to wireless off.

    I'm not sure, I'll have to check this next time it happens, I'll let you know.

    Cheers

    If you're getting "limited connectivity" the wireless hasn't turned off or disappeared; just disconnected. Please show the following for when you have a good connection and for when you get the "limited connectivity."

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Hey Thickdude,

    I'm assuming you've already rebooted the router, so are you able to "ping" the wireless router when you're experiencing these problems? Please report back any error message you receive.

    Hi guys,

    I just had the wireless drop out again...


    DM says that this device is working properly

    I also tried disabling and enabling the wireless device but it did not solve the problem, i still had to reboot.

    After restarting the router, i still cannot ping it except if I plug in the ethernet cable (which i can do without restarting). As far as I can tell, the router is working fine. As soon as I plug in the ethernet cable, i can internet access straight away and there doesnt seem to be an internet outage at all, just the wireless drops.

    Sorry for the long post, i was going to cut out some of the ipconfig log but just in case the full log helps i left it in.

    Any ideas?

    In the "down" case you have what appears to be a good IP configuration.

    What I find puzzling is the lease periods. In the "down" case the lease was obtained August 6 and is for 5 1/2 days. In the "up" case, which I'm guessing was after a reboot instead of before the failure, the lease is for 1 day.

    Did you look to be sure that both those times you were connected to your network, not a neighbor's?

    What lease period is set on your router?

    It's definitely my connection as all my neighbours have secured networks that I dont have the passphrases for.

    Well, I just noticed that my wireless dropped out and its about the time it was due to expire. I have had a look through the documentation but i cannot find how to set a longer lease period nor can I see it in any of the settings.
    The manual is http://documentation.netgear.com/wndr3700/enu/202-10434-01/usermanual.pdf and the model is RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700.

    Do you think this is the likely cause of my problems (i.e. the lease expiring is the root cause), or just another example of the wireless network being disconnected and that any disconnection (lease related or otherwise) could cause the problem.

    Is there an easier way to obtain a new lease without rebooting?

    Sorry about the dumb questions by the way, I know very little about DHCP and wireless.

    Normally the lease is renewed half way through, so it should never expire. A firewall can block the "Dhcp renew" port, and cause this problem. What non-Windows firewall or security suite do, or did, you have on the machine? I guess it could be blocked by the Windows firewall also, but you would have to deliberately do that.

    I also could find nothing in that manual about the lease period. Usually it's in the "LAN" or "Dhcp Server" section. Attachments are examples from a Belkin and a D-Link, respectively.

    Well, I may have finally found the problem.

    After thinking a bit more about DHCP I decided to check the event viewer for DHCP problems and I found this:



    The IP address lease 192.168.1.32 for the Network Card with network address 001742F202B6 has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).

    I searched online and i found other feedback with the same issue on a similar model (from http://milo.com/netgear-rangemax-wireless-n-gigabit-router-with-4-port-ethernet-switch).

    I had a look at your screenshots and found the equivalent part on my router and there is definately no option to configure lease time so it looks like i wasted a couple of hundred dollars and I should go buy another wireless router... any reccomendations on what brand should be more reliable?

    Thanks for all of your help, at least know I know the problem and can finally fix it :)

    As an afterthought, it's interesting I dont notice this problem on my mobile phones, xbox, wii or my girlfriend's computer... the gaming machines get rebooted all the time but I'm not sure why it's not consistently a problem with the other devices.

    I don't know either, but my guess is that they do not have the same firewall problem.

    If you suspect the router make sure you have the latest firmware for it; then reset it to factory default settings and reconfigure it. These steps will clear a lot of router issues.
