Equium - cannot find all networks to connect

Not very computer savvy so will try to explain the problem as best I can.

I can connect to my internet connection via ethernet cable, but cannot connect wireless (although I have before).

The wireless function is enabled and the orange light comes on. When I open connectivity doctor and go on the radar screen, my internet connection appears (along with a few others)
When I hover over the connection icon at the bottom of the screen, it says that "wireless connections are available", but when I click it it establishes that "windows cannot find any network" then understand that there must be an easy way to solve this problem, it can not find all networks to log, mine or one of my neighbors!

Hi paulymart,

Which model of laptop, you have exactly and that you've updated the driver WLAN?

    It does not work! I've tried disableing the * bleep * thing, but then my wireless card cannot find all of the networks in range. After that, I uninstalled the AC Tool. the same thing. I'm really running out of patience with this boatware! Why couldn't they just leave windows to manage networks and Wi - Fi?

    1. update the driver on the LOCAL network card (mine is INTEL 5100 AGN)

    2. restart

    3. set the WLAN to "Uprooting" autoconfiguration service (in Services)

    4 restart the gain!

  • HP Laserjet P1102w: Cannot find my network when connecting HP Laserjet P1102w

    Yesterday I bought a new HP Laserjet P1102w and I have problem of printer setup to work on the wireless network, I installed the software and when he asked me the weather to set it up via USB or wireless, I clicked on a wireless then he told me to enter my network SSID and I typed it correctly but he said "the printer could not communicate with any wireless router or" using the supplied access point SSIDS ' then I tried to check the network in the list but no network appear.

    The printer works fine with USB, but I need you to connect wireless.

    Hello

    I have this printer so I know how it is difficult to set up the printer using the wireless connection on your own.

    If your router supports Wi - Fi Protected Setup (WPS), it's the easiest way to configure the printer on a wireless network.

    Hello

    Maybe this can help.

    These steps and tell us where is the breaking point.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    ------------------

    The wireless card drivers much also install utility wireless of the seller.

    Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

    ----------------

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

    If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

    party like Hello and NetMagic 3rd network managers can block local traffic too.

    ---------------------------

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

    Above everything is OK, you must be able to connect to the router.

    Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

    If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

    Enable security wireless after you eat to make a functional connection.

  • Windows cannot find any networks, but Ubuntu can! (X 32 Vista Home Premium)

    I recently replaced a faulty laptop computer mother board with an identical model (only difference is a newer version of the BIOS). After restarting Windows (Vista Home Premium 32 bit) I can't find the networks wireless where I can see usually eight networks at least an unsecured connection, but now I get nothing.

    I replaced the wireless card Atheros with an Intel Pro 3945ABG driver and installed the latest version and that I still get the same error "Windows cannot find any networks", I can get access to the internet via an Ethernet cable but I am unable to connect wirelessly. If I try to manually configure the wireless connection, I get "unexpected error occurred".

    I started the system from a CD of Ubuntu to check that it was not a hardware problem. Wireless card perfectly, sees all the networks, connects and works very well.

    It seems that something inside Vista has failed since even change the wireless adapter for a different manufacturer and the results of the modeling in the same error, pointers?

    Kind regards

    Jason.

    SOLVED

    It turns out that Kaspersky Internet Security is at fault and he was very happy to work via ethernet it had mutilated all WLAN connections.

    Removal of Kaspersky and all of a sudden all the wireless networks have re-emerged.

    Kind regards

  • DMA2100 cannot find wireless networks

    Hello

    I just unpacked it 3 DMA2100 to use at home with my HTPC. I started to configure the first DMA2100 but are struggling to find my wireless network.

    A network is found, and it's the ISP´s Internet router that goes right in the Internet (and so I don't want to use ).

    I connected the DMA2100 to a wired gigabit port and configured it and did the firmware upgrade to the latest firmware (. 12).

    I then rebooted the DMA2100 and retried to search for networks. Same problem, only my ISP´s router appears.

    Then, I turned off the router ISP´s (thinking maybe it's a bug that shows just the first available wireless network), restarted the DMA2100 and tried again. No networks where found.

    I have 4 laptops in the House all are my two wireless networks and use them successfully. I have 3 Xbox 360 that uses wireless and find all networks with success. I have a PS3 which is all networks and use them successfully. In addition, on most devices, my neighbours networks shows (two) on all other devices, depending on where I place it upward.

    Not on the DMA2100 tho.

    My personal router in the House is a D-Link (curse) DIR-855. I can't say I m satisfied with it, but I had no problem with other devices connected to it. The SSID broadcast is turned on and I ve never seen not see if friends up or so come with their laptops.

    I seriously need some advice and support to get this working. What can I do to make these DMA2100 find my wireless network?

  • Qosmio G30-182: Drops Wlan connection & then cannot find wireless networks

    I use currently v.11.1.0.100 driver for Intel(r) Pro/Wireless 3945ABG, which is the last driver I found here at Toshiba.

    My problem is that I lose my wifi connection, randomly my home wlan (using WEP protection) and my University (WPA-Enterprise). After the connection drops, it is impossible to find all nodes wlan unless I reboot.

    Anyone have any suggestions on how to fix this? It is a bit frustrating to have to restart randomly because I need my network connection!

    It's OK, it s good to hear that a BIOS update solved your problem. :)

    Hope that this wireless broadcast could be resolved with the same procedure on other models of the machine.
