    Ok, here goes this rather longish sad story of mine.

    I have Casda DSL modem provided by telecom.

    I have TP-Link wireless router connected to the DSL model with UTP
    cable, configured to connect to the dsl with PPPoE, router is
    connected, has ip address and dns entries fine thank you.

    My HP 7400 notebook has both ethernet and wireless. If I connect utp
    cable between notebook and router, everything is fine, and I can surf
    the internet all day long.

    However if I connect notebook to the router over wireless, I can easily
    access router on, but Internet mostly does not work. I.e.
    first it does not work, then after some XY minutes it starts working,
    works some time than dies again and so on.

    while connected with wireless, ipconfig /all on notebook shows
    everything ok as far as I can see, correct IP (, dns:
    192.1681.1 gateway , etc.. but internet is flaky.

    My radio signal is great (5 bars)

    I have patched wireless drivers on notebook.

    I have tried using the fixed IP on notebook, fixed DNS, fixed gateway.
    I have tried each an every WiFi encryption mode including no

    I have tried every wireless speed and channel.

    Before TP-Link router I was trying with Canyon, and simptoms were
    exactly the same. I thought that getting me a new router would solve
    the problem so I bought TP-link, but the problem remained exactly the

    To resume: if I connect over ethernet internet works fine. If I connect
    wireless connection to the router works fine, but internet commes and
    goes and is mostly unusable.

    I am getting desperate :)

    Is it possible that there's interference? Microwaves? Cordeless
    phones? Another wireless device nearby?

    If not, then I suppose it's time to start swapping things out on a
    larger scale.

    Try a different wireless adapter on your laptop. Get a cheap usb
    adapter and install it. See if you still have the same problem.

    If the substitute adapter works, then it's in the laptop's built-in
    adapter (+installation+settings).

    If it's still the same problem, then test another laptop/pc with the
    same router and same adapter. If that works, then it's in the OS on
    the laptop....
