  • Set up a home network on a Vista computer. Added my XP computer on the network. I can go on the internet but the signal strength is 'very low' 98% of the time.

    I used a d-link WBR-1310 Wireless G router to set up the network on my Vista computer.  On my XP computer, I used an adapter G USB 2.0 Wireless d-link WUA-1340.  Both computers are single room apart and most of the time, the doors are open, so there is no major obstacle to interfere with the signal.  This is my first experience on the implementation of a network and I must admit I was a little unsure of myself.  I don't know if I have some incorrect settings or if the problem may be something else.  It is a WEP secure network but I don't think that's the problem.  My XP computer on the network automatically signs as soon as it starts.  I am trying to download the LLTP from Microsoft on my XP machine, but I don't know if this could be the problem.  I've been struggling with this problem for almost 4 weeks and I'm getting very frustrated.

    PLEASE, I WELCOME ANYONE WITH AN IDEA OF WHAT I HAVE DONE WRONG, TO ANSWER!

    I'm sorry, but I read your post and I do not understand what the problem is you want to solve.  Is something that does not properly?  If so, please give us the details: what you're trying to do, what happens when you do that, the text of the error messages, etc.

  • Help fix the husband XP2 system (we have home network, mine is Vista, its XP)

    My husband's computer was working fine until its automatic update installed Windows XP3 several weeks ago. It is literally cascaded by being not able to repair. I wiped his drive completely cleaned, reistalled XP1 (this is the version of the software that we have on the disc). Download Mcafee total protection and then slowly starts the upgrade and install Basic programs in the next few days.  The new facility has failed from the beginning after installing XP2. Blue screens, other software does not properly, not computer shuts itself off more frequently... and now, not even system restore will work. Uninstall XP2 and restart?  It is not due to a virus, spyware, malware etc. I have McAfee and Advanced SystemCare, plus Windows Defender.  What should I do to fix this mess?

    I was running hard drive and memory tests, using the tools of diagnosis of the Ultimate Boot CD or the manufacturer of the computer.

    I'd also install service packs before you install an antivirus program.

  • Connection problems XP machine to the rest of the home network

    I have a home network with a Vista machine configuration, a NAS and a XP computer. The Vista PC is able to read and write on the NAS and sees the XP computer. PC XP have internet access but can only see the SIN as uPnP and cannot read or write on the NAS and does not see the Vista machine or WORKING Group also. Both computers have the McAffee protection and 'trust' between them.

    What I've done wrong? Can someone please help?

    Hello

    Regarding SIN, you should check the Server NAS Manuel and software making sure that it is compatible and configured properly with both computers.

    Regarding the Windows share.

    For the best newspaper of the results of each computer screen system and together all computers on a network of the same name, while each computer has its own unique name.

    Make sure that the software firewall on each computer allows free local traffic. If you use 3rd party Firewall on, Vista/XP Firewall Native should be disabled, and the active firewall has adjusted to your network numbers IP on what is sometimes called the Zone of confidence (see part 3 firewall instructions

    Please Note that some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled).
    If possible, configure the firewall correctly or completely uninstall to allow a clean flow of local network traffic.

    If you end up with the 3rd party software uninstalled or disabled, make sure that Windows native firewall is active .

  • Sudden home networking issues

    Product name: Macbook Pro 13 inch Retina early 2015.

    OS (when the problem started): Yosemite 10.10.5

    OS (now): El Capitan 10.11.5

    The problem

    So yesterday my Mac Wifi connection dropped suddenly. So, I moved to lightning Ethernet connection which has varied between does not and VERY slow, almost unusable. I work from home online, so the last 2 days I was not able to do anything.

    I can connect to Wifi, Mac said Internet: accessible. I can ping. But can not browse and other tools such as Google Drive and Dropbox are unable to connect.

    So far, this would indicate a problem with my network or my router, rather than my right to the machine? However, my Android phone works fine with Wifi.

    Things I've tried:

    I've been on Yosemite 10.10.5. I followed all the troubleshooting steps basis and the following:

    • Reset my SMC.
    • Reset my PRAM.
    • I turned off the Bluetooth.
    • I deleted the files in Network preferences to reset a reboot.
    • I "forgot" my home network to reset it like that.
    • Running reports "wireless diagnosis" everything is "as planned."
    • Attach to the Wireless on my Android Nexus 5 X hotspot. Connects to the Wifi but not Internet after 10 seconds. Sometimes not at all.

    Then, I took a backup and upgrade to El Capitan. The strange thing is, about an hour after the upgrade, my ethernet cable was working fine again! About 14:00 yesterday at 09:00 today when I turned on it to start working.

    NOTE: I connect to the network fine, and Google Drive and Dropbox plugins start synchronization. Full report 'sync', then, after about 10 seconds, they say "unable to connect". Holding "option/alt" and clicking on the Wifi symbol in the toolbar says "Internet: accessible. Indeed, I can 'ping' very well. There is no loss of data packets. So could it be a software on my machine which has suddenly become crazy and prevents connections other than the pings? I have run Avast Anti-virus, but which has worked for months and is running as I type this. Similar posts often get answers their questions about firewalls and proxies that might cause the problem. I only have Avast.

    Affirmations:

    If it was a problem with my router, my phone would not have a problem too?

    If it's a problem with my Mac, why would Internet suddenly started working again after a while?

    I write this in a coffee shop, using their Wifi and it works fine. I don't have whatever it is off on my machine. Yet once, which suggests a problem with my network rather than the phone.

    Is this something that could be fixed to an Apple Store? As I suspected, it works very well to the coffee then probably it would work fine in the Apple store and they don't know what to do.

    I thought only try you geniuses first!

    Thanks in advance.

    It is very difficult to debug an Internet without Internet problem.

    First of all uninstall AVAST from the system. then open system preferences > network > enter your network > what is place please do as automatic. What, the other DNS settings, preferred networks etc please post.

  • Sharing files on home network - Vista Home Premium 32 and 64

    Hello people,

    I searched for hours, I made countless different steps to try to understand this point, and yet I'm still far away.
    I have two computers on my home network.
    -Machine 1 is Vista Home Premium 32-bit and is connected via a wired connection to my NetGear router.
    -Machine 2 is Vista Home Premium 64-bit and is connected via a Wireless connection to my NetGear router.
    I have a WD WorldBook connected to the Machine 1 via USB and I would like to be able to access it through my home network on Machine 2.
    Here are my settings that may be useful to know.
    Machine 1:
    -Cable
    -Network: NotURInterwebs (private network)
    -Working Group: DISCOVERY
    -The discovery of the network: WE
    -File sharing: WE
    -Public folder sharing: OFF
    -Printer sharing: OFF
    -Password protected sharing: WE
    -Media Sharing: OFF
    Machine 2:

    -File sharing: WE
    -Public folder sharing: OFF
    -Printer sharing: OFF
    -Password protected sharing: WE
    -Media Sharing: OFF
    If I go into start-> network on the Machine 2 I see the other computer and the router, but when I click on the Machine 1 I get the following text:
    Windows cannot access \\Machine#
    Check the spelling of the name. Otherwise, there could be a problem with your network. In an attempt to identify and solve network problems, click on diagnose.
    Error code: 0 x 80070035
    The network path was not found.
    However, when I go to start-> network on computer 1 and click on Machine 2, I have no problem connecting.
    Does anyone have an ideas that could help me understand what is happening?
    Thank you!

    Hello

    Thanks for the detailed information.

    We need additional information to help you with the problem, please answer the following.

    What antivirus application do you use?

    I suggest to change firewall security settings, or disable the security software on the system and try to access the location.

    Method 1:

    Disable the firewall on the Machine 1 and check the status of the issue.

    Enable or disable Windows Firewall

    http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Firewall-on-or-off

    Note: You should not turn off Windows Firewall unless you have another firewall is enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

    Note: In addition to a firewall, you must also be an antivirus and anti-malware program to help protect your computer. Install Microsoft Security Essentials or another antivirus and anti-malware program and update it. Many of these programs update automatically.

    Method 2:
    Error code 0 x 80070035 indicates that the network path was not found. This problem occurs if the NetBIOS over TCP IP is not enabled in Windows Vista. Please follow the steps below.

    (a) click on «Start», enter "NCPA. CPL"(without the quotes) and press ENTER.

    (b) right click on the connection you use for the local connection, and then click "Properties".

    (c) click on the button continue to check the permission of the administrator.

    (d) click to select 'Protocol Internet Version 4 (TCP/IPv4)' and then click 'properties '.

    (e) click on the button "Advanced" in the opened window. On the "WINS" tab, select 'Enable NetBIOS over TCP/IP' and then click 'OK' to save the setting.

    The following article presents NetBIOS over TCP/IP.

  • Machines Vista cannot see the rest of the home network

    I don't know what's happened recently, but here's the thing.

    I have a home network, 1 Vista desktop, 1 Office XP with shared USB attached, 1 drive NAS (running Linux kernel I think). All devices set to the same workgroup 'HOUSE '. Until recently, I could see all the devices in the Vista machine with the selection of 'network' of the Explorer.

    Now I see that me, the wireless router, and if I turn it on, an another Vista laptop. The Vista laptop has the same situation - he sees only the vista desktop and router and anything else3.

    I can connect to the XP computer manually by entering \\computer_name\external_drive_name and even with the NAS drive. I can't see the with the Vista Explorer.

    I can't say exactly when it happened, but is has been in the last month. I see the console of restoration that there is an update Tuesday 4/11, but if I try to restore before this date of restoration fails.

    Discovery network, file sharing, etc., are always turned on. I tried to do a complete reset of the router but nothing helped.

    FYI - Norton of 365 security card option fortunately shows everything on the network, so I know that all devices are in the same workgroup.

    Any advice would be greatly welcome.

    I solved the problem with advice from another forum. I forced the desktop computer to become the master browser by setting 'MaintainServerList' in the registry for the 'yes' rather than 'auto '.

    I can now see all the connected devices.

  • I can not connect computer vista laptop to my network home, but I can connect to other networks. Other computers can connect to my home network very well. This can be corrected?

    My laptop runs Vista and I've not had problems connecting to my home network wireless until a week ago or not.  Then, trying to connect, I see other available networks, but not my own.  When I try to connect manually, it says that the network already exists.  Other computers, macbooks, are able to connect to my home network without problem.  I am able to connect to a network on my laptop fine unsecured wireless.

    I could 'solve' the problem or get reconnected with a restoration of the system to an earlier date, but it only lasts a day or two.  I searched for another fix and tried many things, including to reset the router, remove my network, and then reinstall, etc, but can't seem to get this to work as if it were - automatic connection as the first network.

    Any help would be appreciated.  Thank you.

  • I have problems wireless on my Acer laptop which has Windows Vista. I am able to connect to my school of university network and used to connect to my home network.

    original title: Wireless on the Fritz

    I have problems wireless on my Acer laptop which has Windows Vista.  I am able to connect to my school of university network and used to connect to my home network (both are networks limited requiring a password or log in).  However, last week my computer stopped connecting to my home network (no one else has this problem with the home network).  I tried to fix the problem, but my computer says that "Wireless association failed because Windows did not receive response from the access point or wireless router."  That said also thatthe connection "(my wireless network)" has been cancelled.  This is perhaps due to a timeout or user action. »

    The only different thing I did last week was click option at my University 'connect long-term' instead of 'connect short term' to their wireless network.  Maybe who has messed up my settings?  That's what my University said of his record long term: "students, faculty and staff also have an option to easily record their computer (or other wireless devices), so that it is not necessary to authenticate each day they connect from the network wireless campus, to resources outside the University.»  However, these settings are saved on their network (I can access it online from another computer), so I think it is unlikely that he messed up my settings.

    I don't really know what the problem is.  Any ideas as to what I can do?  I don't want to reset my computer everything.

    Thank you!

    Hello

    You can view these methods:

    Method 1:

    I suggest you to disable any program of security on your computer and check if it solves the problem.

    After reviewing the question you must reactivate the security on your computer program.
    Note: Run the computer without antivirus software or firewall is a potential threat to the computer; Be sure to activate security software after completing the troubleshooting steps and after identifying the problem.
    Method 2:
    I suggest also allows you to check in SafeMode with network.

  • computer Vista Home network is not visible from the XP computers

    I have a home network with 4 computers. Both run Windows XP, Windows Vista is running and
