  Hello

  I thank you and wish you the same.

  I see that your problem has been solved using the HP driver that you mentioned on Thursday, November 18 in your message and the Express.sys is a problem with Windows install.

  I suggest to install the version of Windows install 4.5 on the system from the link below and then update the driver from the link that was attached to your question before and check.

   

  Step 1:

  Install windows install 4.5

  Windows install 4.5 Redistributable

  Update the driver from the link you mentioned in your previous post.

  I suggest you to check with TP-link if this model is compatible with Windows XP or not.

  Computer is Toshiba C855D.  Windows 7 Home Premium 64-bit.

  Wireless adapter is Realtek RTL8188CE Wireless LAN 802.11n PCI-E NIC

  I'm the only computer in the whole of the network that has this problem.  All other users around me have no problems connecting to the internet on the network.

  Would appreciate any help.

• Equium A60 - no wireless network connection

  Hello world

  I have had a good look through the forums and can't find anything related to this but my apologies if this has been addressed elsewhere :-)

  I set up a wireless home network with a Windows XP desktop computer with a router and a laptop old Win98, WinXP SP2, which I can't connect and an Equium A60. I installed two different network on the A60 USB adapters, seems to be okay with all of them except that there is no "wireless network connection" listed under network connections Control Panel. Both cards work fine on two other machines, so there must be a problem with the A60. I installed an adapter and then uninstalled before trying another.

  Under control-> connections Panel Network, I can see an old broadband connection and the connection to the Local network (which is allowing me to connect to the router via Ethernet, so that the router will work), but the wireless network connection icon is not there. The driver for the USB adapter makes its appearance in Device Manager and is reported as working properly, but if it worked correctly then (I think) a wireless connection icon should appear - it happened with my other WinXP desktop.

  Any ideas of what could be the cause?

  Thanks in advance
  Gareth

  Hello

  I guess that the external WLan USB stick has been recognized one installed correctly. You said it appears in Device Manager. Are you sure that the WLAN USB key has been recognized to 101%? !!

  If the WLAN USB key is recognized correctly, check the properties of this stick. (I think you should right click and then click on properties).

  But if the stick was not recognized, you must verify the properties of the single USB ports and power safe mode.
  Choose the USB single root hubs in device, right click, properties, tab power management Manager and disable the option called allow the computer to turn off the device to save energy.

  So maybe it helps

• Wireless network connection

  Hi SANJIT_78,

  ·         The computer is connected to a domain environment?

  ·         Are you facing any performance issue with wireless network connection?

  ·         What operating system is installed on the computer?

  The computer you are using apparently have a wireless network interface installed in it and therefore can detect and connect to any available wireless network. The dlink network is the name of a wireless network available in your area and your computer to connect to this wireless network.

  Wireless networks more private need a password to connect to them and therefore are protected. But the dlink network to which you are connecting is apparently a public wireless network, and it doesn't have a password to connect to it. So which allows any user to connect their devices to this network wireless. Due to this insecure wireless network mode, your computer displays you the message "the information transmitted through this link may be visible to others". If you want to connect to this wireless network, I suggest you first protect your computer with a good program antivirus and firewall.

  To enable the Windows Firewall on your computer, you can check this link:

• Wireless network connection does not

  I can't access a wireless connection with my computer wireless network connection. The icon in the bottom right of the screen shows a red X and says 'not connected wireless network connection. The wireless on my keyboard button does not illuminate

  I tried to change the channel on the new ADSL2 wireless router and refreshed looking for wireless connections, but still not found connections. I have not used a wireless router before and never used a wireless connection with this computer so I don't know if the wireless card works or not, if the properties of the wireless adapter indicate that it works. Is there a way to check if the computer's wireless card is running or connected and if not, how can it be connected? Thank you

  I finally understood by trial and error, why I was unable to connect wireless to a modem, that you sent me. In my control panel, I found that the properties of HP Wireless Assistant had "Hide status icon" checked, so I checked it and the icon came in the bottom right of my screen. I left then clicked that icon and it showed the wireless and bluetooth was OFF so I went in and it now works.

  Why HP support could not help me in what I don't know, I just got the race!

  Hope this helps others with similar problems.

• 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!
