    Hi!

    I have a HP pavilion dv5 laptop with windows vista.
    2 days ago, shortly after i installed comodo firewall, the wireless
    connection went dead... 'connected with limited access'.
    and there are 2 other laptops that works fine wirelessly with the same network.
    I already uninstalled comodo, and since then tried any solution
    i could get my hands on off the web. maybe there is something i'm missing.
    the network diagnostics gives 3 options:

    -the network adapter "realrek PCIe FE Family Controller" is experiencing driver or hardware related issues.

    -make sure your internet protocol bindings are correct.
    ensure that internet protocol version 4 (tpc/ipv4) and internet protocol version 6 (tcp/ipv6) are selected in the configuration for the network adapter "local area connection".

    -the network adapter "Broadcom 802.11b/g WLAN" is experiencing driver or hardware related issues


    I checked the device manager and both of them are working fine. i evan reinstalled them just in case.

    tcp/ipv4 and tcp/ipv6 are both selected and automatic.


    host name .............:Owner-pc
    primary dns suffix ...............:
    node type .......................:hybrid
    ip routing enabled....................:no
    wins proxy enabled .................no

    I tried the tcp/ip stack repair that i found in one of the topics here.

    I'm also adding a screenshot of Xirrus Wi-Fi Inspector.

    any help will be greatly appreciated!

    Let’s take a look at the status of the network adapters

    Device manager:

    Hold the Windows key and press R, then type devmgmt.msc

    Please respond to all the following steps.
    1. Under Network adapters, please tell me all the devices listed.
    2. Are there any devices under Network adapters that have a red x displayed?
    3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?
    4. should be enabled and working properly.
    5. If error code,what is it ?

    It would be best if you could post a screen shot of Device Manager with the Network adapters and Other devices sections expanded.

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.

    -Realtek PCIe FE Family Controller

    no red X, no yellow ? or !. no errors.
    both are enabled and working properly.

    I might suggest,downloading the adapter driver from HP.That will eliminate the possibility of driver corruption.And force a bindings re-build.
    Also,How did you uninstall Comodo.Did it have an uninstall proc with it ?
    Did you try a system restore to a date prior to the comodo install ?

    tried downloading the drivers.
    I uninstalled Comodo through the software uninstaller,
    and after that used a comodo removal tool i found somewhere just
    to make sure there's nothing left.
    and for some reason I didnt have a restore point before the comodo installation,
    just one right after that, which i tried to restore to and didnt work.

    Ok:This is a wild guess,but I did have an instance like this.
    The solution was to change the wireless channel.
    In your case I might select channel 11,just because you have another very strong network next to you on 7.

    Assuming a router here.
    Log onto the router,and depending on your maker,probably either the wireless or security section.That is where you should be able to change the channel.Your user's manual should detail this operation.
