My laptop Sony VAIO with Vista will not connect and stay connected to my wireless internet.

My laptop Sony VAIO with Vista will not connect and stay connected to my wireless internet.  All other laptops in the House are perfectly.  Internet disconnects, says local only, then reconnects constantly making internet hard work.

Hi Tinkerbellfancolorado,

  1. When is this last work fine?
  2. Do you receive an error message or error codes?
  3. Recent changes on the computer?

There could be several causes for this problem.

Try starting with these methods.

Method 1

Step 1

  1. Open Network Diagnostics by right-clicking the network icon in the notification area, and then click diagnose and repair.
  2. Make sure that all cables are connected (for example, make sure that your modem is connected to a working jack or cable phone connection, either directly or through a router).
  3. Reset your modem and router. Remove the power cord from the modem or router, wait at least 10 seconds, then plug in the modem and/or router back.

Step 2

Another reason may be windows disable your network adapter to save power. Turn off the power saving option in the properties of the network (wired network only cards) card:

  1. Open network connections by clicking the Start button, clicking Control Panel, clicking network and Internet, click network and sharing Center, and then clicking manage network connections.
  2. Right-click on the connection and then click Properties. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  3. On the Networking tab, click Configure.
  4. On the power management tab, clear the allow the computer to turn off this device to save power option, and then click OK.

Method 2

Temporarily disable the firewall, and check the status.

NOTE: To re-enable the firewall after check you the status. If you are connected to the Internet or a network during the time that your /firewall antivirus software is disabled, your computer is vulnerable to attacks.

  • My HP Pavilion laptop g6 will not connect to any wireless internet access

    I have dealt with this for a while now, and it just happened to no part I turned on my computer one morning and it would not connect to my wifi. I've tried EVERYTHING. My computer allows me to plug in an ethernet cable and the router and use the internet like that. I know it's not the router because I use the internet on my iPhone and tablet. When I try to connect to the internet, it has a red X where the wireless icon used to be, now the icon looks like a computer instead monitor the small bars. When I type my button wireless on my keyboard, a message appears and warns me that I just got my wireless turned off, but no matter if it is off or on this little button always has the light on orange. I can't understand what is happening and I would appreciate if you could help me!

  • Laptop Sony vaio with windows home premium 64 - bit randomly bluescreening

    I had one laptop Sony Vaio for Christmas and a month later he badly infected and had to be wiped. My friend helped me to wipe the laptop and reinstall the drivers and a copy of windows 7 64-bit edition Home premium. A few weeks later I noticed he started bluescreen randomly. A few weeks after it starts to crash any Web browser randomly. He seems to hate Fire Fox, more than any other. It's getting pretty bad now and I really need help, trying to get my laptop in good working condition. I tried several anti virus and malware research but they apparently find nothing every time. I unfortunately did not get a disc of windows 7 recovery of Sony and would like to try to solve this problem without having to pay more money but if needed to.

    Your Sony has been provided with a partition hidden restore and you need to follow instructions Sony to create the defined recovery disc, then visit Sony support and find out how to access the hidden restore partition and the defined recovery disk.

    If your friend has destroyed the car when it installed win7, and where he got that?, you will need to contact Sony support to request the recovery disc game, for which there will be a small fee

  • HP Officejet 6500 a: printer will not connect to the wireless network.

    I got this HP printer for a while and it worked fine.  Our old router is out and we had to get a new one.  Installed perfectly and printer continued to work properly.  The password for the router was ridiculous, that's why I changed it to something much more simple to remember.  Since then, my printer will not connect to wireless internet.  I have a ~ and reinstalled the printer but still have the same problem.  I thought maybe to try the former password would, but who does not work either.

    Anyone has any ideas that might help before chuck it and go and get a new one altogether?

    Thank you.

    Easy things first.  Turn off the router and the printer.  Turn on the router and wait 3 minutes.  Turn on the printer and see if it connects to your router.  Status?

    If no joy, temporarily disable all security in the router.  Now try to connect the printer to your SSID not guaranteed without password.  Status now?

    If OK, go back and add WPA2-AES with your simple password.  Status now?

  • HP 7520: HP 7520 will not connect to the wireless network

    There is some additional information to

    http://forums.Xfinity.com/T5/home-networking-router-WiFi/HP-7520-will-not-connect-to-wireless-networ...

    on this issue.

    Have several APs for a single wireless network allows the printer foolish law.  (Not a Repeater, a second AP connected to the local network with the same configuration of network for security, etc.).

    I solved this problem.  In accordance with the discussion on the link, the problem is that the printer cannot connect to a wireless network if there is greater than 1 for a wireless network (SSID) name wireless access point.

    This thread has had several useful suggestions, but what finally solved the problem, it's the second point has access to a mode where I can create a 'virtual' access point and, above all, a SSID associated.

    Note that not all access points or routers support virtual APs, but this function seems to be more common over time.  Older models is not able to do that.  However, a new access point is sometimes cheaper than a new printer.

    If you do not understand the jargon in the procedure below, I recommend that you find someone who does, then they can do it for you.

    Solution:

    1. On one of the wireless access on the network, create an a new virtual AP with a slightly different name SSID (for example < name of the network - > _1), on the same VLAN (usually VLAN 1).  You may need to put the AP in "multiple AP mode" or something similar, and then restart the AP.  All other settings (DHCP, security, mixed mode b/g/n, etc.) must be the same for the new SSID.
    2. Run the printer Wireless Setup and connect it to this new SSID
    3. Confirm that the printer can be seen by other devices on the network

    Tips:

    • Check the security is the same as the original SSID, Alternatively you can create a vector of insecurity in your network.  Do not WEP-128 when the other SSID uses WPA2 AES, for example.
    • The AP I had had several resets to make it work because of the mode and parameter changes.
    • If you connect the SSID but cannot connect to or be seen by anything on your network, check the new SSID/AP is in the same VLAN as the original.
    • Because the printer is not roaming, and the speed is not a problem for me, I used the access point that could support this solution, which is deeper and slower than my primary AP.  I have not noticed any problems.

    The printer has been reliable on the wireless now on the new SSID, 48 hours.

    I have not upgraded any software on a client of the printer (PC, Mac, phones).

    I think that it is a positive confirmation that the problem is with the implementation of the printer of the stack of network and not with the driver or client software on remote devices.  The 802.11 protocols provide for a network name (SSID) wireless with several access points using different MAC addresses.  I suggest this HP look into this as a potential bug with their network printer for the 7520 protocols stack.

  • SONY Vaio VGN-AW360J will not power

    Hi all

    I'm new to the Group of users, and this is my first posting.
    I have a SONY Vaio VGN-AW360J, the keyboard is for quite awhile, buggy not allowing the good boot-up, lock up, creation of random key entries and sorting. I found that if I opened the laptop, access to the slick KB then disconnect and reconnect it LT would work normally until I later had to reboot for some reason any. I ordered an exact replacement KB and I'm waiting for delivery is however now the LT does not power on at all. I checked the presence of 19.5 VDC at the level of the connector on the main Board after taking power, but don't know where else to check even if I can with my simple digital multimeter. I did all the procedures proposed on the site of Sony support without change.

    The symptoms are the following: no indication of power to the power switch, no green light. DC power is present on all four positions at the level of the connector PCB (PCN1). There is no change with or without the defective original keyboard connected and no change with all removable devices disconnected i.e.: CD/DVD drive, hard disk and RAM all removed from the main Board.

    Then, Oh, my darling Sony Vaio is completely dead in the preverbal waters of my digital life. My big question is, does anyone have knowledge of this problem and is at - it no reasonable or logical hope through the necessary repairs, if any?

    TKS,
    Dave S.

  • Satellite A205 with Vista will not start

    Hi, need help.

    Trying to help a friend with his laptop which is not booting. Its an A205 with Vista.

    Machine boots only a blank screen (not blue) with a mouse cursor.
    I tried safe mode and it does the same thing. I tried the Toshiba recovery disc supplied and the same results.

    I even downloaded a separate copy of recovery Vista on the Internet and who doesn't. I'm ready to start from scratch and completely reload the OS, but I can't seem to understand how to do this with the discs I have.

    Any suggestion would be great.

    TIA

    What happened when you start the laptop?
    You can enter the BIOS settings?
    See Toshiba welcome screen?

    If you have a recovery media for this model of laptop, you can try to install it. Your laptop to start press F12 for boot options. Put the recovery media in the optical disc drive, choose the CD/DVD drive and press ENTER.

    The optical disc drive is the first boot device and recovery installation should begin. Please let us know what exactly happens when you try to do.
    Please write about what you see on the screen.

  • Laptop will not connect to the wireless network

    Hello

    This is a security feature of each wireless router I've ever seen, although I wouldn't be surprised to discover that some router didn't do it. You need to check your router admin pages to see if mac address filtering is in effect. Address filtering Mac prohibits access to the router by any unauthorized network device. All network devices have a unique mac address which you can find through opening a command prompt (click Start, then type cmd and press enter) and then typing ipconfig/all. The output refers to your device Wireless 'physical address' (mac address) and will be in the format hh-hh-hh-hh-hh-hh, where hh is a hexadecimal number (A - F and numbers 0-9), dashes are not important and may not be required when you enter your mac address in the router configuration.

  • Vista will not connect to Netgear WPA/WPA2 wireless router

    HP Presario laptop with Vista Home Premium. Added Service packs 1 & 2 in a timely and all upgrades of MS Vista through 8/11. Laptop does not work on the wireless network using a new Netgear N300 router with WPA/WPA2-PSK security.  Roommate has Windows 7 on his laptop and connects very well. I thought that these Service packs were supposed to solve the problem of Vista-WPA? My laptop connects fine with the router if I use an Ethernet cable directly between the laptop and the router. NetGear argues that it is a matter of MS Vista. I missed a special fix?  Any suggestions?

  • Vista will not load and continually reboots, recovery disk does not start.

    I have a Dell with vista on it. Recently, it has automatically installed an update and now it does not load Windows at all. It goes to the screen where I have the opportunity to "start in safe mode" "safe mode with command promt", "last known good configuration" etc. and none of these work options (all start loading them upwards and then the computer restarts just itself).

    I tried to put in the cd of installation for vista, but it won't start. I changed the options in the BIOS so that it starts from the CD first, but then it just goes to another blue screen that says: there was some sort of system faliure, and the only option is to restart the computer.

    I also tried to connect an external dvd player to see if he was not playing the disc because of a defect in material, but the same thing happens.

    I also tried out the RAM and it put it back again (a single website suggested I try this).

    Nothing seems to work! And now, I am out of options and have no idea what to try next - help!

    http://support.Dell.com/

    If it does not start where install Recovery DVD from Dell, you will need to contact Dell at the above address.
    As you say, you have changed the boot on the appropriate drive order and still nothing

    It would seem that you have a deeper problem that just a straight reinstall the problem.

  • Windows Vista will not start and cannot recover

    I have a desktop PC HP Compaq Presario, which has about 2 years. The problem started when Windows Vista was not able to start. It would load up on the "COMPAQ" screen and then it would just go to a slider black white screen with a flashing white light on the top left. Now that I've seen a lot of discussions with this similar problem, but it seems that people would rather not reformat in order to lose any important data. But in my situation, I have some important data on my computer so reformatting would be fine, except...

    -Recovery system won't work. I insert the 1 system recovery disk, all files loading correctly, it allows me to choose if I want to reset the computer to factory settings, I click Yes and it finishes the reformatting step. But then the problem comes when I insert disc 2, original content relocation step. It fills up to 10-16% and then I get a blue screen of death STOP: 0 x 00008086. I tried SEVERAL times and the same thing happens.

    -The next thing I tried to do is to fix the computer via a copy burned Windows Startup Repair. Loads everything up, I spent the page where I choose my language, currency, etc. The problem comes when I get to the System Recovery Options. There is no listed BONES and a box appears and says "Searching for Windows installations", and then it stalls just on this pop up. This problem is quite recent, because before there is no pop up and there is simply no OS listed, so I still could not repair or restore in any case.

    -Before, when I was able to go into the advanced options on the Startup Repair disk (when he was not of "searching for Windows installations" pop up to stall on), I'd go to the command prompt in attempt to chkdsk/r C:. All bad sectors or groups or something else would be fixed, and then he would hold to step 5 of 5 when checking free space.

    -In addition, I tried to make a diagnosis of memory via the Startup Repair tool. That's what I get:

    File: \boot\memtest.exe

    Status: 0xc000000f

    Info: The selected entry could not be loaded because the application is missing or corrupt


    Furthermore, I cleaned my computer, it is now almost completely free of dust. In addition, I can't get into the BIOS, I can't get into safe mode, and now I can't have in the command line

  • ENVY 4520: printer will not connect to the wireless network

    with wireless on Printer Setup Wizard, printer detects the network but when I enter the key to encryption (correctly), he comes back with a message "Unable to connect to the network".  The printed report suggests the address filtering MAC can be activated.  But I checked and it is specifically DISABLED.    The printed report indicates a FAILURE on "no filtering."

    Please notify.

    After struggling with this for two days and after the announcement of this question and all by downloading the HP doctor, I noticed that the printer had suddenly cured himself. I'm not sure what I should credit this miraculous healing. Thank you I guess?
