    Hi there, I have a laptop which has always connected to this wireless network fine until yesterday. The wireless network seemed to suddenly just disappear. There are three other laptops in the house which can still detect that wireless network and connect to it except that one now. I have restarted that laptop and the network reappeared and it connected. But when it was restarted again, the network showed just for a minute or so and the laptop cannot connect and then the network disappears. I've restarted it many times now and it just shows the network for a brief moment, trys to connect and then the network disappears.

    This is the info for the laptop:

    Tech Support Guy System Info Utility version 1.0.0.2

    Processor: Intel(R) Pentium(R) CPU P6100 @ 2.00GHz, x64 Family 6 Model 37 Stepping 5
    Processor Count: 2
    RAM: 2998 Mb
    Graphics Card: Intel(R) HD Graphics, 1275 Mb

    I'm not sure what to do. Can someone please help me out, thank you in advance.

    can we see a screen shot from inSSIDer and click on timegraph and just select your wireless signal

    I have taken a screen shot of the laptop which cannot detect the network and a screen shot of this laptop which is on the network using the programme. The network wanted is TNCAP3746B3

    your on channel 13 along with a few others

    and all channel 13's appear to disappear

    log into the router and change the wireless to use channel 1 - see if the wireless now disappears at all

    US are not allowed to use channel 13 or 14 - so maybe something going on there on the laptop - I see you are in new zealand - so 13 should be OK

    Your suggestion worked, thank you. I've learnt more about wireless networking now. Thank you again.

    thats quite strange you have the intermittent issue - but you would get interference anyway from the ch13 signals
