• A Wi - Fi (Wireless LAN) connection is disabled in Device Manager

  The laptop is HP Pavilion G4 running Windows 7 Ultimate (64 bit).

  I just re - install my laptop Windows 7 Home Premium (64-bit) for Windows 7 Ultimate (64 bit).

  But I just realized that there is no "HP Connection Manager", so I downloaded it from the internet.

  When I turned on the wifi of "HP Connection Manager", he says "Wi - Fi (Wireless LAN) is disabled by the Device Manager".

  What should I do next?

  Thank you!

  Hello:

  You will probably need to install the driver for the wireless card there.

  If you see a device network controller listed in the Manager of devices, then you certainly need to install the driver for the wireless card model that your laptop uses wireless.

• Linksys WPC55AG, WPC54GX on wireless LAN, "connected to the AP, but Internet is not found.

  Aloha, finally a forum thar actually solves the questions, mahalo.

  These two wireless network adapters used to work properly with my DSL modem Westell 7500. Now, not so much.

  I can wire Enet cards pcmcia network very well. I see my Brother MFC885CW wireless printer.

  I'm on a gateway 9100, Win2k, Service Pack 4 running.

  Linksys utilities show that I received, but do not send bits.

  ipconfig gives 0.0.0.0 for the IP address auto configuration

  I looked at the parameters of the DSL router, I don't see anything strange of course.

  I also use wireless MAcBook Pro, airport, very good works. Hmm

  Any thoughts?

  The WPC54GX allowed ascii/text in box 1 WEP key, the WPC55AG has failed, only hex characters. However, after a search fast on another computer, I found an alpha decoder spell and managed to enter the WEP key in hexadecimal form, which I was able to confirm the MAc RPN calculator. Network cards do not seem to do the conversion correctly. I knew this because of my string of characters in the password.

  Also, the dual-band has been assigned, when he did at all, a "unrelational", (best way to put it) the IP address of 169.254.81.145, instead of a 192.168... as I was expecting.

  So with a little effort, both network adapters are now connected to the internet, and ipconfig shows well, as valid information.

  Some once said that I spoke in hex, there you have it.

  Thank you very much, I would say that the problem is solved.

• Automatically use the wired on wireless LAN connection when using the docking station

  Hey guys!

  I use the my T500 with the Advanced Mini Dock @TheDude recommended in this thread: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T500-Recommended-Compatible-Docking-Station...

  I had almost a month now, and whenever I anchor my laptop I have to pass the connection wireless switch off hard or using FN + F5 and extinguish this particular radio.

  Is it possible to have the computer automatically choose the wired connection when it is available, otherwise use the wireless radio?

  I use Windows 7 Prof 64 bit.

  Thank you

  ThinkVantage Access Connections (AC) can be configured to do this. Change your location profile and change the order of the adapter associated with this place, for example, order first as Wired and Wireless second.

  When I am connected Wired and I pull the Ethernet cable, AC will switch to using wireless automatically. When I put the Ethernet back in, it starts automatically by using the wired and wireless don't report limited or no connectivity (which means that the switch has occurred). You will have to perhaps set up wireless in AC power options, i.e. disable radio when not in use (I did not sentence again).

  This could be similar to a docking station solution. Mine is without docking station; When I'm at the office and go to a meeting, I pull the wire and have continuity.

  Ideally, the CA should provide a solution. But it may take some fiddling.

• NIC WRT1900ACS shows all devices wireless LAN connections

  You just bought a WRT1900ACS which seems to work well, except that the NIC appears all devices as it is connected to the local network instead of on the 2.4 GHz band or 5 GHz to which they are attached.  This is true for our iPhones and Chromecast devices that aren't able to connect via WiFi.  Any thoughts on a way to solve the problem?

  

  You will need to wait for the next firmware update and hope they fix it.  I guess that your WRT1900ACS updated when you set up and it has no doubt the 1.0.0.172978 firmware version because this version really screwed up for the network card so that it is not usable.  The 1.0.0.168229 original version came with a problem of restart, the next vesion 1.0.0.169041 does not solve the problem of restart, the 1.0.0.172978 last seems to have solved the problem of restarting, but presents Newwork card problems and in addition several people (including myself) reported that the most recent firmware version reduced the power of 2.4 and 5 GHz TX on 10dBm compared to previous versions of firmware.  If you want to follow all the discussions on these points follow the section entitled "new firmware for WRT1900ACS 1.0.0.172978.  This topic is up to 10 pages now and continues to grow.

• Problems with Realteck 8187 B wireless LAN adapter

  I am running Windows XP and since a month started having problems with my Wireless LAN connection. The installed adapter is a Realtek 8187 B. When I start the connection opens briefly, then begins to show the low connectivity with yellow dots under the icon on the status bar. Sometimes I have connection then connectivity closes its doors as soon as I pass my home page.

  Other times it falls back after about 5 minutes. I can usually clear it by restarting the computer sometimes twice. What I need to download an updated driver.

  Thanks in advance

  > Do I need to download an updated driver.
  I think you should check the portal Tosiba WLAN and install the latest version of the driver Windows XP Home edition. Do it first and check the functionality.

  Then go to the site of the manufacturer of the device and get even more recent (Realtek, Intel, or one that makes the device) and
  try to install again.

  Download - SAVE - go to where you put it-click on - RUN AS ADMIN.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

• Satellite L750 - Wireless LAN is disabled, no my home WLAN connection

  Hello, I have some problem with my Satellite L750. It has a called Atheros AR9002WB-1NG wireless adapter which seems to be in place.

  When I turned on my laptop I noticed it was not connected to any network, so I searched and found that it could not find. I checked on my phone (on which I am writing this) and there is my network and many others who are available to connect and mine works great on my phone. I tried to reset the router and nothing happened, I could always connect on my phone and tablet.

  I tapped into the wireless software and found the so-called "ConfigFree". In this, I found "Connectivity Doctor". He said that there was a problem with the adapter, and then, after having discussed below, I found he said that 'Wireless LAN Off' next to a red picture of a switch.

  Does anyone know how to reactivate it?

  You can activate WLAN card by using the FN + F8 key combination?

• Tecra M3: Cannot connect to the wireless LAN

  Hi all

  Since yesterday I have a problem with my wireless connection:
  When I turn on the without orange wire the led light show but on the network connection, the message is: 'Not connected' and try on icon Office not start and display a red cross.

  Why? Where is the problem?
  I have upgrated readers... but not found
  Before yesterday, the connection worked fine.

  Help me please :-((

  Thank you

  Hello

  I put t know what icon on the desktop you want to say but perhaps you intervene on the Wlan icon that appears in the taskbar.

  In any case, to establish a connection to the wireless LAN laptop side switch must be enabled and you must also use the FN + F8 key combination to switch to the WLan.

  Did you check that?

  By the way; If there is a software problem, I recommend to use the System Restore tool and reverse the operating system to the beginning.

  Good day

• 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 just bought a new PC (foxconn) who has a 802.11n wireless Lan card, my connection is very poor but my connection on my laptop compac and iPad are excellent. Is there a way I can get a better connection with this lAN card?

  Hello

  Check with the assistance of FoxConn, their documentation and online drivers. Don't assume new products
  have up-to-date drivers.

  The router may also need a firmware update so check with its creator.

• An error occurred while renewing interface wireless network connection: unable to contact your DHCP server. Request a expires.

  I use an Acer Asspire One with Windows XP. We have wireless through AT & T Uverse. The netbook has an Atheros AR5007EG Ethernet card.

  A number of things have taken place lately: I had not used the Acer for some time and the battery was dead and would not recharge. I could book until when it was plugged, but could not get on the Internet. I found online that the solution to the battery problem was to download a new bios that worked wonderfully and it is now loaded. Recently, our AT & T router died and was replaced. I put the new WEP keys in two other computers, and they connect to the Internet. I can't connect to the Internet with the Acer. I tried ipconfig / renew and get the error message: "an error occurred during renewal of the wireless network connection interface: unable to contact your DHCP server.» Request a expires. No operation can be performed on Local area connection while it has its media disconnected. "On the tab"Choose a wireless network", it shows my network and said"absorbing the network address"but nothing happens. When I do ipconfig I see that there is no IP address.
  I took the computer to Starbucks this morning, ran ipconfig / renew and she acquired the IP address and I was able to connect to the Internet. I brought the computer home and tried and failed to connect. The IP address is back to 0.0.0.0 and the error message appears when I try to renew it.
  I hesitate to make a lot of changes since it was working with a different network.
  Original title: IP address is missing
  These forums are wonderful. I tell myself that I've saved the cost of a new battery using the bios, I found on a forum!
