Problem with WiMax connection on one laptop

  1. Hi everybody...
    I am facing a rather peculiar situation. My bsnl wimax connection on my laptop has stopped working for last few days. Although it is running just fine on other laptops. It shows connected in the taskbar but I cant access modem through 192.168.1.1 or connect to internet or use torrents (speed in torrents is like 0.1 kbps, shows seeds and leeches but almost zero speed). One thing I remember that I did different before this problem started was to install a bluetooth device on my laptop. Don't know if it is becoz of this or not. Plz help me.

    What version of Windows?

    Taskmgr on Win/7 -> Networking Tab shows Bluetooth & Lan Connections-- look for activity

    Also Control Panel->Networking & Internet -> Network Connections will show
    • Bluetooth
    • Lan
    • Wireless
    do not allow BT + Lan (+ Wireless) at the same time - - it messes up the routing table
    (cmd prompt -> enter ROUTE PRINT)

    The Broadcom NetLink (TM) Gigabit Ethernet is configured correctly & you should be just fine.

    ? is the bluetooth also running ?

    Please keep the NAS OFFLINE while we work on this issue. I suspect configuration issues and if true explains your problem. If this configuration
    Code:

    is the result AFTER your reinstall of the networking,
    then you should be able to perform
    • ping 8.8.8.8
    • ping google.com
    If these respond correctly, then there are other issues.

    that time should NEVER occur on your router address - - BIG issue and you out to look for a firmware update
    Your DNS is not accessible - - AND it's using the IPv6 address rather than the IPv4.
    Looks like WiMaxCPE is at fault
    great were it NOT for that timeout - - comment on your router above
    also great, the lookup was successful but the timeout is STILL a problem
