New wireless network does not appear on any computer

Thanks in advance for any help. OK, so I have a HP office connected to the internet through a router WRT54GS.  I had 2 laptops connected to the NICU my wireless router. A (HP) laptop has built in wireless modem/adapter.  The other laptop Dell was NICU equipped with a wireless adapter card.  The problem is that the adapter on the basically dead Dell laptop, I don't give no internet connection.  So I tried to install a more recent network card wireless linksys with speed on the cell phone booster.  The instructions asked me to press the orange button on my router Cisco access point.  I knew thatd be a problem.  While the laptop connected to the internet, my old wireless network seems to be deleted.  Installin the new card on the Dell laptop has created a connection b/t it and the router. The other laptop (HP) is now offline and not even a slate of the new network.  So I tried to create a new wireless network on the main desktop computer.   Now this new network is not detected by the wireless or portable printer.  Other networks is detected if.  Or the original linksys network is detected, Im not sure.

OK sorry for any confusion, but my basic problem is that my new wireless network is not detected on the laptop or the printer. I tried unpluggin the router. I also tried to manually in the network settings.  I also tried to disable the firewall on my main computer. Nuthing worked. I checked the Device Manager, everything seems fine.

My router is just old? Its at least 4 years

I don't know what to do. Thanks again for your suggestions.

NVM, I got the impression to work. just installed it on the laptop wireless.  I still can't get the 2nd adapter linksys to laptops to work. I'll ask for help in this section of the adapter.

  • Wireless network does not appear without diagnose and repair when the PC is turned on

    My wireless internet works fine when my laptop is running and up to 6 weeks ago, it was automatically available whenever I ran my laptop. Now, when I turned off and turn it back on, my laptop does not access my home network wireless until I have activate the "diagnose and repair network system. This system corrects what ever was wrong and active my network connection. It seems that I have some sort of 'switch' miss-set or the value manual (?) instead of ' Auto (?). Can someone tell me what I need to do to clear up this problem.

    It is difficult to identify what could be wrong.  I recommend that you delete the current wireless network connection entirely (make sure that you remove them completely - in the section Connections page sharing and management as well as the major networks wireless).  Then recreate the connection to go from scratch using the appropriate settings (copy them down before you delete the 'old', if necessary) affecting particular it automatically to connect and see if that solves the problem.

    I hope this helps.

    Good luck!

  • My wireless home does not appear on as a network available on my work laptop and always did before.

    My wireless home does not appear on as a network available on my work laptop and always did before.  He brings up and connect on my laptop. I have a Linksys broadband router - summer use it for at least two years with no problems until this.  I know that my wireless works on my laptop because there is an unsecured network listed in the available window.

    A really strange thing that happened two weeks ago (and I don't know if it's related) was my personal laptop was fine during several hours - then he kept abandonment of the internet connection.  I couldn't keep him connected - reboot etc didn't work.  I've not logged again until today - and that's what I use now.  He connected very well today.

    My work laptop had been connected to my wireless ealier in the week, but when I tried to connect as usual Thursday night he has not logged automatically as it has always done in the past.  Nothing has changed.  Security patches that my company had sent through this week have not downloaded until after that I tried to connect and couldn't.  There is nothing new - he had no reason to think I should not have automatically connected as I have in the past.

  • Unable to connect to the network and wireless interface does not appear in ipconfig/all on Vista32

    My niece has a laptop of HP under vista32 who cannot access the network wirelessly or wired.  She is in College and needs the laptop on the network as soon as possible for his class work.  I tried to reload the driver wireless driver (Atheros AR5007 b/g) and reset the tcp/ip stack using the command netsh addressed in the microsoft article, but nothing works.

    I brought the laptop to work where we have an unsecured wireless lan (called comments) for visitors and the laptop can go out and find all points of access wireless including comments.  When I select the comments and try to connect it times out and tells me to watch driver and tcp/ip connections.

    Another clue may be that the wireless card does not appear when I type ' ipconfig/all', or the adapter wireless and wired adapters are not displayed:

    C:\Users\Admin>ipconfig/all

    Windows IP configuration

    In the case where somone has this same question, I wanted to post my final resolution of the problem. I backed up its data and restored the laptop to factory default using HP restore and now everything works fine.  Better I would say loading Zone Alarm on Vista was a bad thing for my niece to do.  Would have been nice to find a magical solution to avoid restoring but never found one.  Even after the alarm zone using their instructions by removing completely, there was apparently a problem with the registry who wouldn't let networks are working properly.  One thing I noticed after that the restoration was the HP Wireless Assistant poped up and told me about available networks, etc.  Assistant wireless didn't pop-up at all whne the cell was dismantled so maybe assistant was broken?  Well, I'm out...

  • HP Officejet 4500 wireless printer does not appear on the control panel

    My HP Officejet 4500 wireless printer does not appear on the control panel.  How to fix it.  I have a laptop Toshiba and Windows 7 Home Premium OS.  Help, please.    rwillm

    Hey,.

    Thanks for the update, rwillm.  It seems that the installation of the printer can be a little messed up.  If the printer software is always installed, but simply lacks the printer, then I would advise to do a little cleaning before choosing to add the printer back.

    • Make sure that the printer is deleted from the file devices and printers
    • Click on one of the remaining printers folder
    • Select the properties of the print server at the top of the window
    • Click the tab drivers
    • Remove all drivers in this window for the Officejet 4500

    Also check in the Device Manager to verify that there is no mention of remaining of the 4500.

    • Click on the start menu
    • Right click on computer
    • Select manage in the list
    • Click Device Manager in the list of questions on the left side of the window that opens
    • Click the view at the top of the menu, and then select Show hidden devices
    • Remove all references to the 4500 in the list of devices

    After making sure of the device is gone, I recommend bike devices in the power circuit: router, computer and printer.

    * Make sure the printer has a valid IP address after switching back on and is connected to the same network as your PC before adding the printer.

    If the IP address and SSID are good for the printer, then try to add the printer with the printer software, you have installed.

    • Click on the Start Menu
    • Click on all programs
    • Open the HP folder
    • Open the folder for the series of the Officejet 4500 G510
    • Select Add a device option

    Let me know how it goes,

    Jason

  • Toshiba Canvio Basics HARD drive does not appear in my computer

    Hello

    I have a HDTB110AK3BA - Toshiba 1 TB Canvio Plus Portable Hard Drive for storage 3.0 Basics and the computer will allow it to connect, but it does not appear in my computer / pc is in Device Manager thought but not my pc

    Please help and Windows 7 or windows 8.1 PC do the same thing.

    Hello

    I found the description of the product of this external HARD disk:

    Product features:
    • USB 3.0 - powered portable add-on storage.
    • Voltage of bus capable USB, no need for AC adapter.
    • Easy to use with no software to install.
    • Adapts to large digital files with spacious storage capacity.
    • Protect your drive (internal shock sensor and ramp loading technology).

    Specifications
    • Capacity: 1.0 TB
    • Interface: USB 3.0
    • Transfer rate: up to 5 Gb/s
    • Speed: 5 400 rpm
    • Average access time: 12ms
    • Cache buffer: 8 MB

    It is a HARD USB 3.0 drive. No doubt the HARD drive is not recognized correctly in windows exploerer due to the low power.
    The USB 2.0 port common feeds only 500mA. The USB 3.0 device must be able to 900mA.
    Therefore, it would be advisable to connect this 2 ports USB 2.0 HARD drive with a USB Y cable
