• Resolved - problem of wireless connectivity "wlan0 link is down.

  Quick update:

  * If you encounter this message, make sure that you are trying to connect to a wireless "N".

  Yes, he is in small print on the box, right, sony will not ask you this when you are troubleshooting.

  * If you rely on Sony for smart assistance, forgetabout it.

  * After the receiver a comment card and to express my disappointment, the call center outsource sent a letter... and when I called to discuss, they were still clueless.

  Sorry, but the support structure is absolutely catastrophic.

  We now return you to your regular programming...

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

  OK, let's go, in detail:

  My Sony dashboard came again, out of the box today. It will connect to my network.

  FYI: My set of skills: I am an engineer of sales network, with an extensive network of Wi - Fi and running in my house.

  After connecting the dashboard and providing configuration information, the message I get is:
  __________________________________________________

  Network configuration
  Failed network connection...

  wlan0 link is down
  did not get an IP address
  Internet is inaccessible
  __________________________________________________

  Like others on this forum, it seems that my dashboard won't "handshake" with my wireless router.

  To try to solve problems, I did the following:

  (Slot 0): both my wireless router and my attempt to connect to the sony dashboard are in my home office, so the intensity of the signal should not be a problem.

  (1) check the connectivity wireless on a multitude of home devices: laptop, TV, iPhone, ipad... in short: Wireless works. Both with fixed IP and distributed DHCP address.

  (2) restart my Rosewill RNX - N4, wireless "N".

  (3) allow my SSID be visible (that I found which helped my LG TV to connect during its initial configuration)

  (4) checked my WLAN settings on my router:

  SSID: *.
  Security mode: WPA2 only: personal
  Type of encryption: AES
  Pre-shared Key: v * m

  (5) restarted the dashboard of Sony.

  (6) wireless seems to work on the sony dash, as the configuration screen of the network about dashboard States:
  ______________________________________________

  Network configuration
  Choose a wireless connection

  ..:| (my ssid is displayed)

  MAC address: (my MAC address of my wireless router is displayed)
  ______________________________________________

  (7) I select my SSID (FYI: nobody else displayed) and click (next)

  (8) place comes the next screen:
  ______________________________________________
  Network configuration
  Choose the key to coding (WPA2-PSK)

  HEX)
  (o) ASCII
  ______________________________________________

  I select ASCII then (Next)

  (9) he asked my key, I carefully enter (.. .slightly annoyed that the screen will not edge to allow me to see all the characters that I'm going home)..., then click on (Next)

  (10) I choose Auto IP, as during the initial setup I keep it as simple as possible... and then hit (Next)

  (11) to the top displays the following screen:
  ______________________________________________
  Network configuration
  Confirm settings

  name: (my SSID) (My MAC Address)
  AUTH: WPA2PSK encryption: AES
  key: (poster in my correct key, read and validated twice)
  automatic IP allocation (DHCP)
  _____________________________________________

  Completely satisfied with it, I select (Next)

  (12) the sony dashboard begins its Network Configuration / connection looking for the network and then...

  (13) the following:
  __________________________________________________

  Network configuration
  Failed network connection...

  wlan0 link is down
  did not get an IP address
  Internet is inaccessible
  __________________________________________________

  (14) in an attempt to solve the problems, I also tried to set up with a static IP address:

  static IP address:
  IP: 192.168.15.20
  Subnet mask: 255.255.255.0
  Gateway: 192.168.15.1
  DNS1: 192.168.15.1
  DNS2: 8.8.8.8

  ... and the results were the same: "wlan0 link is down.

  (15) as a final step, I reset my wireless router to have no. SECURITY at ALL. Guess what? "wlan0 link is down.

  At this point, I'm at a loss for what I could do "evil".

  I welcome comments from other users, either to continue to solve the problem or sharing what you did to resolve your issue with connectivity.

  Thank you.

  Well, here I am, a moth and a half later.

  After speaking to Sony technical support...

  After sending the camera back to Sony...

  After having been informed by Sony that this point had problems, they need to replace parts, AND they were going to send me a new device to save time...

  I get a new, and it has exactly the same features / problem.

  So I try another router, same problem.

  Guess why?

  Because I have my network running "N" and it's a Sony wireless B/G device.

  Anyone who has mentioned in technical support... The point on the replacement due to damaged items was total BS.

  If you have a network of "N", it will recognize your SSID and even to recognize the security there.

  But it does not connect.

  Once I changed to a mixed G/N wireless environment, it connects.

  For example, you might say my own question... should have known.

  However, Sony sells a device "B/G" when almost everything comes standard "N"...

  Not cool, Sony... Not cool.

• Satelite C50 - B cannot connect to wireless local area network

  My brand new straight out of the box Satelite C50 - B cannot connect to my wireless network, when you are running Windows 8.1.

  When you run the wizard for the first time user, it was unable to connect to my network to register. And I have been unable to connect after starting the OS, even if my thread was visible and the signal strength would be strong. I entered the security network key, but the message came back "unable to connect to this network.

  However, when I started on a USB key to run Linux Mint 17.1, it took less than 5 seconds to connect to my wireless network. If the Toshiba hardware work properly, as also my wireless LAN.

  If I plug in a network cable, same Windows connects to my network and Internet.

  However, given that the C50 - B satellite comes with Windows 8.1 both of wireless capabilities, I was hoping someone here might be able to help me get a wireless connection in Windows.

  It's really strange. I have S50 - B and WLAN works properly. I used my laptop connected to several different networks and everything was OK.
  You can try to test with different wireless LANs?
  Have you checked all the WLAN settings?
  Try restarting your router.

  I mean if your laptop can detect WLAN, this means that the hardware is enabled and working properly. There must be a problem with the WLAN settings.

  Also check the advanced power settings, and then set it to maximum power WLAN.

• How to make the computer to look for SBRIO on a LAN connection when wireless connections LAN and are active

  Hello

  I plugged my laptop to a SBRIO using a cable, I also did the same mask subnet the SBRIO and my wireless connection for laptop is also active. I run an application to transfer files from the network to the SBRIO. I was able to download the files from the network using the wireless, but when I try to transfer the files from the laptop to the SBRIO the application attempts to use the wireless instead of the connection to the local network. Is there anyway that I can apply to use the LAN connection instead of wireless?

  Thank you

  Mouda.

  You must manually configure the settings for the SBRIO and map NETWORK cable on the PC. They must be presented on the same subnet. Using the crossover cable, you can configure your PC to use an address like 192.168.0.10 with a subnet mask of 255.255.255.0. Configure the SBRIO to use an address as 192.168.0.11 with a subnet mask of 255.255.255.0. The PC uses the network connection by default for all addresses that do not match the specific subnet on teaching secondary (cable in your case) NIC

• I lost my wireless connection, says no wireless connection available... but they are!

  Hello

  I use a laptop dell inspiron with windows 7 - I set up a wireless connection with talk talk about 6 weeks - and things has of worked - this weekend the small icon at the bottom of the laptop had a red throug crodd there - when I clicked on "Open the network and sharing Center" he registered the wireless connection, I use and had a maximum strength indicator , but a red cross through the connection.

  I checked the wireless router with my computer pc laptop and work - blaze they work correctly. So I have concluded, the dell laptop itself (which is about 6 weeks old).

  I plugged the yellow wire - and makes hard wired - and the internet works on the laptop.

  Keeping in mind I don't know anything about computers or how correct - can someone tell me if I've lost a program and where/how to find it or not it sounds like a defect on the laptop

  I'll be very grateful for any help

  Thanks domi

  If the Dell is still under warranty, by all means, file a claim and see if a new card does the trick.  It is a Forum of Vista, this is why everything is on Vista - you should have posted in the Forums of Windows7 if it is the OS you use - then the tips and links correspond to your system.  I suggested to contact Dell in a previous post - not specifically for this, but it would have developed in the conversation.

  Even if it is not under warranty, there is a good chance that the card is the problem if the system can connect wirelessly with another device (which means that the configuration is correct and connections work and Vista has no problem with the wireless operation).  If you can, try to make sure you can return it for a full refund if you attach and encounter the same problem.

  I hope this helps.

  Good luck!

  Hello @adityarai82,

  Thank you for visiting the Forums from the HP Support! The forums are a great place where you can find solutions for your problems, with the help of the community!

  I read your post about the WiFi problem and wanted to help you!  I understand that you have tried the troubleshooting steps a lot already, without success.

  Try to review these steps, offered by community member @Great-Christine-Tree:

  First of all, we have a step by step guide to guide you through the process of diagnosis here:
  Troubleshooting your wireless network and Internet access

  A second option is to try the following steps:
  Powercycle the network:
  1. turn off your laptop.
  2. unplug the power to your router.
  3. disconnect the power to your modem.
  4. wait at least 45 seconds.
  5 reconnect the modem and wait for it to come back online.
  6 plug in the router and wait for it to come back online.
  7. turn on your laptop and test your connection.
  
  Turn off the power to the adapter:
  1. open Device Manager. (Win Key + R > type devmgmt.msc > OK)
  2. expand the network adapters.
  3. right click on the Ethernet adapter / wireless, and then click Properties.
  4. click on the power management tab.
  5 remove the check mark next to allow the computer to turn off this device to save power.
  6. click on OK.
  7 test cycle.
  
  Reset the TCP/IP settings on your PC:
  1. go to your start screen/menu and type CMD.
  2. right-click on the command prompt icon and select run as administrator.
  3. in the window that opens type "netsh int ip reset resetlog.txt" without the quotes and press ENTER.
  4 restart your PC and test.
  
  It can also help to reset the winsock catalog:
  1. go to your start screen/menu and type CMD.
  2. right-click on the command prompt icon and select run as administrator.
  3. in the window that opens type "netsh winsock reset" without the quotes, and then press ENTER.
  4 restart your PC and test.
  
  Reinstall the NIC drivers:
  1. download the drivers from here , but do not run them again.
  2. go to your Start menu/screen and type Device Manager.
  3. expand network adapters.
  4. right click on the wireless adapter and choose uninstall.
  5 install the drivers downloaded in step 1.
  6. restart your PC and test.
  
  Test an ethernet connection:
  Explicit. Test if the problem persists on a wired connection to the adapter hardware troubleshooting wireless can be directed to the appropriate areas.
  
  Test another connection:
  Many people excluded their home network as a problem if another device working on the same network. Networking is not as simple as that. Each device interacts differently with your router or modem and it is impossible to exclude the settings for this device until the laptop has been tested on another network.
  
  If these steps do not resolve the problem, try this document published by Microsoft for network management issues: wired and wireless network problems. You can change the operating system with the drop-down list in the upper right of the document.

  I understand that you notice a decrease in speed wireless on the x 360-15-w100nt laptop computer ENVY when running off the battery voltage.

  You can check and adjust the power options on the system as it is probably trying to save battery power by reducing wireless performance.

  If you're still having problems, you can follow the steps described in this document to troubleshoot the network settings and internet wireless.

  Please get back to me how that happens. To show that you like, or are grateful for my post, please click the Thumbs up below.

• Vista SP2 wireless connection drops

  People, I know this question has been asked before, but I can't find a solution to my problem.  I've had my Dell laptop for about 6 months now and it worked perfectly, without any problem wireless connection.  On Sunday, August 9, I installed Vista SP2.  It updated no problem at all, but once he did his final reboot, it connected to my wireless router for about 5 minutes, then dropped connection.  Now, when you restart it only connects for a minute or two wireless then abandons connection.  I then uninstalled SP2 but it has not solved the problem with wireless.  My wireless adapter is an Atheros AR5007 and drivers are all up to date.

  Anyone know how I can fix this so that my wireless signal stay tuned as he used to pre SP2?
  Thank you.

• Wireless fails & can't get wireless connection tab is displayed

  I can't connect to the Internet wirelessly. I have a Dell Latitude E6510 with a Half-Mini of WLAN Wireless-N DW1501 card.  According to the website of Dell and the Dell technician who tried to help me, I in fact installed the right driver for the card: the DW WLAN Card Utility.
   
  The driver recognizes my U-Verse (router) gateway, but my browser cannot see the web. I've tried everything I can think of but to no avail. I tried:
  turn on/off Wireless Auto Configuration
  -deactivation of the DW WLAN Card Utility
  -modification of the parameters of the utility (for example, turning off the option to let the utility manage wireless)
  -Uninstall and reinstall the utility
   
  VERY IMPORTANT: A constant is that the wireless network connection dialog box does not always display the Wireless Connection tab. I think if I can just come back to this tab, I can have Windows configure my wireless and everything will be fine.
   
  Help!
