Upgrading a network to Windows Vista to Windows 7 computer

I have a home network (XP based) which works very well for years.  Three computers, two printers, and all worked very well together.  It's just my wife and me, and network security has never been a high priority.  Now, I want to add new computers to the system, one is a Dell with Windows Vista laptop. and it is a HP with Windows 7.  I followed the Network Wizard I used before creating the network; I created a file and was walking and it ran on all of the old and new computers.  The two XP machines can still talk to each other fine, the Vista machine can see two XP machines - but the machines XP get a window "permission error" when trying to access the Vista and WIndows 7 machine is on an island, he sees not all computers and all computers get a login screen before you can access the Windows 7 machine; even if we have no password on the Windows 7 computer.  As I said - it's just my wife and me, and we have no password or sign ins on all machines and would like to keep this simplicity.  FYI - all thte computers can access the internet fine and all use the same router to do.  Please tell us how can I better return to the situation that I had before where I could sit to one count; access to all the others, without a bunch of security and authorization issues.

  • What version of windows is required to upgrade a desktop with Windows ME computer to use wireless internet?

    We have a 2000 Hp desktop computer? with windows ME and just recently had wireless internet access. The system is too obsolete to connect even with our router. Now, what version of Windows is necessary for us to spend to be able to connect?

    Unfortunately, a Windows ME operating system cannot be upgraded.  Its time to recycle that old computer and buy a new one with Windows 7 preinstalled.  Here are a few examples.

  • Unable to connect to a wireless network with Windows 7 computer laptop.

    After resetting my router netgear wireless home network, I have not been able to access my own network with my laptop. I already had access to the internet with a wireless ethernet cable and ankles bound to the router. After reset the netgear router, I was able to access the internet from two other laptops XP and an Acer mini wireless with no problems at all. But my new laptop Toshiba with Windows 7 could not connect, even if he could detect the network. I tried all day even resort to the ethernet socket and wireless cable, but even that would no longer work. I was able to connect using this same cable attached.

    Hello

    Seems that the Wireless does not work on the Dell.

    This is the process to try to find what wrong with it.

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

    Assuming that wireless router is configured correctly, it is a signal and the wireless card on the computer is physically in.

    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.

    To ensure that if there is Wireless Utility a seller is not running with the native Windows wireless utility (Service WLAN).

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

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

    Some 3rd AV/Firewall/security software part, s costume keep blocking aspects of Local traffic even it they are off (disabled).

    If possible set up the firewall correctly, /Security costume 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.

    Hello

    Depends on hardware configuration required on later operating systems, and also find out if the manufacturer of the laptop computer is supported and provides drivers for operating systems later as to whether it is possible or feasible to upgrade or not.

    There is no free upgrade Vista to 7, 8.1, or 10.

    Follow these steps before you buy Windows 7.

    Microsoft sells more than 7; Try Amazon.com.

    Go to your computer / computer laptop manufacturer Web site and see if Windows 7 drivers are available for your make and model computer / laptop.

    If this is not available, Windows 7 will not properly work for you.

    Run the "Windows 7 Upgrade Advisor.

    need a new key for installation to install my old copy of vista on a new computer. I upgraded windows 7 which was the copy of vista on the pc

    And if your copy of Vista was preinstalled on your old computer, it is classified as an OEM license is not transferable.

    I bought Windows Vista Home Premium and got a free upgrade to Windows 7, which I have installed on Computer1.  Can I install Vista on a second computer computer2 and still be legal?

    Is same question with versions of Microsoft office, if I have multiple versions allowed to install an earlier version on a second computer and stay legal?

    No, unfortunately not, when you upgraded to Windows 7 indeed renounce you your right to use Vista. But keep the product key and Vista media where you need to perform a clean installation of Windows 7 again.

    For MS Office (according to license as some allow multiple installations) If this older version is not in use you can install it on this computer second no questioned asked.

  • A hard time with the drivers for Vista Home Premium computer laptop computer network with Windows 7

    OK, I've read tons of information on that and I'm stumped.  I have an Epson Stylus CX6600 all-in-one printer.  I have my Windows vista Home premium networking with my 64-bit Windows 7 computer.  I go to the step where the machine Vista attempts to connect to the printer on the network, then it asks a driver.  The driver file is already on the vista machine.  I installed the latest drivers from Microsoft and epson on the Windows 7 machine and he always asks a driver.  Can someone point me to the exact file name and the location of the driver in the vista vista machine so I can simply copy and point to it my windows machine 7.  I did the updates from Microsoft to get all the latest drivers.  Thank you.

    You do not install the Vista drivers on Windows 7 computer.
