A PC on the network does not connect to internet

This has proved to be very difficult.  A PC on my network has been to connect to the internet.  I thought it was because I installed a new router, especially when I moved the PC to connect directly to my cable modem - when he was working.  But I also thought that upgrading to Windows 7 from WP would take away any problem on the PC - but it didn't.  Thus, with the help of an expert on a Linksys forum, I've implemented (to my satisfaction anyway) is not a router problem.  Indeed his inspection of ipconfig/all and stuff has shown that everything was normal with this PC as well as others.  The PC collects the IP address, etc., it is simply not receiving data from the internet.  I had already checked that it was not a firewall, using Norton Uninstaller issue to ensure that everything was gone.  The network adapter works and I've updated the driver.  I have since also rolled back to XP for doing the same thing and still nothing.

The expert from my router comment was "well, the IP of the computer configuration is correct and the router works as you have other computers that connect to the internet via the router. It seems that if the installation of Windows has serious problems on this computer. I suggest that ask you in a Microsoft forum on how to reset the configuration of the network on your computer to make it work again. So far I would say that it is not a problem with the router or caused by the router. »

The only thing I would add is that system restore has failed for a while on this PC.  Of course I would have used it to try to solve this problem, but I can't.  I tried various fixes for whom these for one, there included opening in SafeMode etc, but nothing worked.

Help please!

Hi, sorry bit slow on this - alert does not.  The answer would have been wired and Wireless does not, but I just reinstalled a Linksys network adapter and hey presto it works!  I haven't been back to try the wired LAN but guess it still does not.  So I think that the diagnosis of network card is OK but incorrectly excluded earlier because the PC said that he was OK and wireless did not work either at this time.  But I guess it's possible that uninstall and then reinstall the Linksys may have released something somehow.  BTW I had disabled the native Windows Firewall also.  Was it wrong?

    IPhone lost 6. batery about to dye, it is not connected to the internet. Im trying to track its location by FIND MY IPHONE, but seems to be offline.

    I'll be able to track its location? or y at - it another way to track its location?

    No, you won't. There is no other way or the other. The only way to find my iPhone to work is if it has been activated prior to the loss, the device is on and it has an active connection to the internet. If one who does not exist, you cannot follow the device. As you say the battery was almost dead, then he's probably already dead. You will not be able to track the device.

  • My wifi network does not connect automatically

    Hi all

    I also deleted the list of networks do not forget and do it again. Any help?

    Much appreciated guys.

  • iPhone connects to the wifi but does not connect to internet

    I have an iPhone running iOS 9.3.2 6s (last updated).

    The phone connects to the wifi network, but even if it's to show the signal strength is good, the phone does not charge any internet content (weather, FaceBook, email, etc.).  If I disconnect WiFi and use the data, it works very well.  We have no problem connecting to the computer or a smart TV network wifi and internet connection.

    This also happens with my daughter 5s iPhone and iPad for my son.

    Sometimes it will work fine on wifi, then a little while later I can't get anything to load. And it can be like right now when I'm at home alone is not as if there's a big load on our wifi.

    We have high-speed internet by cable (25 MB/s download speed) and a router Lynksys EA3500.  Encryption is set to WPA (not WEP).

    I tried to go into my phone settings and reset the network.  Always problems.

    It's really frustrating because you eventually switch to our mobile data and use it instead of our data ' wifi '.  And then to go on our data on our phone plan

    Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

    (1) perform a forced reboot: hold the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears. Leave the device to reboot.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth).

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) backup and restore the device using iTunes (ask for more details if you wish).

    (9) go to the Apple Store for the evaluation of the material.

  • HP Pavilion dv7 - 3188cl: HP Pavilion does not connect to Internet (resolved)

    I recently got a HP Pavillion Entertainment, model number dv7 - 3188cl, for me to use for a class at the school by my uncle. Before the recovery, everything worked perfectly well. My uncle asked me to reset the computer, so we used the recovery disks that wiped the hard drive successfully but then refuses to reinstall the operating system. Instead of getting another set of recovery disks that I've used a Windows 7 install disc to reinstall the OS and he did so successfully with one flaw, the laptop does not connect to the internet.

    I tried to connect via ethernet and it does not find my WiFi network. I suspect his lack a driver and checked for drivers on the HP site but he said that there is none. Any advice would be greatly appreciated, and if there is no driver for this I would be grateful if you could tell me where to download from.

    Thanks in advance.

    Update: after some search Intel had the good driver needed.

  • 114 the desire does not connect to Asus all-in-one wireless but connects to the wireless network

    I just bought my HP ENVY 114 e all-in-one last week and I tried to connect it to my computer (Asus all-in-one Windows 7 64-bit) and while he wil connect to my wireless very well my computer (or my cell phone which is also an Asus running windows 7 64 - bits) cannot identify it.

    Using the disc doesn't help nor did try manually to add in 'Add printer' in my computer and all the interest to get this particular printer was because it was wireless. If I have to plug in a USB key then I have saved money and bought a less expensive model. All my devices are on the same network, and their firewalls is turned off so that it does not hinder the process.

    When you browse the drive Assembly he asks the IP and I get it exactly as it is on the screen printer that I even printed it out and double checked 5 times and it was exactly the same, but he keeps asking for me to be reintroduced to it since the computer cannot identify the printer.

    Any help would be great I prefer not to have to pack up this thing and take it back...

    Unfortunately, the router and the printer do not get along at this stage.  The IP address changes too often and it is possible that the router has its own firewall.  A large number of firewalls, outside the Windows Firewall, sees a lot of traffic from hpnetworkcommunicator.exe and blocks preventing the software to find the printer.

    I saw this model of router and it doesn't have a built-in firewall.  Unfortunately, I could not see their manual without you register on the site.

    It may be preferable to set a static IP address for the printer in the router's routing table.  To do this, you acceding to EWS the router.  If you don't know how to set the printer's IP address in the router, you can try to contact the vendor of the router.

    Otherwise, I would recommend checking the firewall of the router.  I saw a router cause problems with an overactive firewall in place.

    If you happen to have an extra router around, you can try to use it instead of Paul's to confirm that it is the router.

    EDIT

    You can try to put a static IP address on the front of the printer.  I'm personally not too successful with setting a static IP address on the front panel when the SAP does not load, but this could be one of those cases where it does not.

    First, print a Network Setup page by going to Configuration > Wireless > Network Configuration > print Network Configuration.

    Then, go to settings > network > IP settings > change to the manual.

    Once it is replaced by the manual, it should allow the IP address, default gateway and the subnet mask.  Use the subnet mask and default gateway of the print network configuration.  Use an IP address that is not in use on the network.  You can change the last number of the IP address on the print.  For example, 192.168.1.50 could be converted to 192.168.1.250.

    Setting a static IP address on the front panel does not set servers DNS which is necessary for ePrint operate on this printer.  Now that the static IP address has been set on the front panel of the printer, try to access the SAP by entering the IP address that comes to be defined in a browser address bar.  If the printer load, you should be able to set DNS servers and be ready to go from there.

    Thank you.

    Tried to reinstall the wlan drivers and utilities already? When you do so, you should check the download pages of Toshiba for the latest version of the driver.

  • Router E1200 works not - error 3005 (and network does not connect by hand)

    I am trying to put in place a new monitor of N300 E1200 and am not having any luck. Using the Cisco Connect ends with an error in step 'Validate the connection' each time, telling me:

    Error: 3005

    An HNAP call to the device failed because the HTTP connection was broken.

    (If it is relevant, the serioal number, type of connection and IP (WAN) all happen as "unknown" in the details of the error).

    I am able to set up the router manually via the access by web browser. I can name the wifi network, set up security, and even see and authenticate to the network of my devices, however, no connection is available when it is connected. (The internet connection is good - when I move the incoming cable between the router and computer, I instantly have access - so perfect this post)

    I also tried all the basic steps of reset and restart all involved several times, but I always end with the same result - 3005 error in the application configuration, then on a manually configured wifi network that seems to be working and can authenticate devices, but does not include any internet connection.

    I am at a loss at this point - here someone has any advice? Thank you very much for your time and input.

    Then you must configure PPPoe in the router, unless your ADSL modem is already acting as a router and not the PPPoe.
