  • Computer shows it's connected, but unable to connect to the Internet

    Original title: also connected but unable to connect

    I have a HP Pavilion a1710n 64 Dual Core Processor running Windows Vista Home Premium.

    The computer shows that I am connected to the internet, but I can't connect to IE or firefox.

    My Internet Protocol Version4(TCP/IPv4) properties shows that the two buttons marked for obtain an IP address automatically as well as the use the following DNS server address.

    My network card is NVIDIA 10/100/1000 Mbit / s, and the computer shows that it works correctly. I tried to do a back roller and re - put to date but still the two marked buttons.

    Large number of background information...

    I was trying to understand why the windows installer did not work on my son's account. I went in systems and changed to start and automatic manual. Rebooted PC and the firewall do not come. Tried to do a restore, but failed and lost all my restore points.

    At this point, I lost my internet connection to know after vainly trying to figure out the problem I contacted an ATT(my internet server) of things ATT me had to do was change the properties to get the use of a DNS server address automatically and had typing me the address. After reviewing the many things ATT concluded there was not a problem with my connection and the PC is configured correctly and suggested that I should speak to technical support and of course, it was not free.

    Tech support determined there was something that crashes me to connect to the internet and had run me malwarebytes. He detected 24 traces of adware and 2 traces of a virus in the registry database. I deleted everything and still no connection to the internet. Next Tech had me run Combofix and says everything should run fine after that. Still no connection to know Tech # 3 had executed me guests of orders with ping commands. Finally, he had me check the auto config button and that's where I discovered the two buttons were lit. Tech said "can't be." Well it is. That's when I tried to roll back the driver, but no luck so tech says only option is to restore the whole system.

    GRRRR... After several internet searches that I'm about to do except nothings saved and whenever I try to use my backup and restore fails.

    Any help would be appreciated. I'm still fairly new to PCs so please be patient with me. Laughing out loud

    I know that my options have been counted, I was able to save what was important and made a full system recovery. I am happy to say that I'm back on the internet.

    Thank you very much for your help and support. I learned a lot on my computer, as well in location wonderful are the microsoft forums :)

    I have a user who has been connected to the internet through our SBS server.  All of a sudden, it can connect to the server (although very slowly) but unable to connect to the internet.  The network and sharing shows that it is connected to a public network not by the domain server.

    Somasundaram Mohammed. Thank you for your help and maybe you will pass on the solution to all those in need. All that is necessary is to download Bluetooth Stack Toshiba 9.10 and run it. However be careful because version 9.0 of battery is not compatible. I have now my two Android phones connected.

  • HP 15-ac152sa laptop: wifi tab disappears from the network settings menu. Unable to connect to wifi

    I bought a new laptop. I connected to the WiFi network with no problems the first time. I have downloaded Microsoft office 2016 (home and student). The next time I turned on the laptop, the icon WiFi in the corner of the screen says "no connection available.

    On the tab "network and internet". There is no tab for WiFi. Initially, I managed to fix it by clicking on the 'network card', 'properties' and on the 'power management' tab, I unchecked the box indicating "allow the computer to turn off this device to save power. This fixed the problem... until the next time I turned on the laptop. It's the same thing and I am unable to connect to internet via WiFi.

    The single adapter in the list here is "Realtek PCI-e FE family controller #2". Still unable to connect to WiFi... Still no WiFi tab under settings "network and internet". Help, please!

    So, the problem was finally solved (fingers crossed!).

    Yes, the Internet access worked perfectly every time when it is connected through the Ethernet cable. Ultimately I phoned the helpline. They checked for the new driver updates (these have been already updated), restored the BIOS remotely and then restored the device to the factory settings. Start of the fault still took place intermittently. This indicates a hardware problem, and the unit was sent for repair.

    The idea was that when the WiFi did not work, the WiFi card wasn't physically visiable in the list of available adapters, nor has the Bluetooth adapter. Apparently in this device, the Bluetooth and WiFi functions are on the same network adapter and apparently those elements should not disappear from the list of available adapters. So the fact that they disappeared together intermittently indicated a hardware problem with the card.

    Now that I got my laptop back and I think that the WiFicard has been replaced. Hoping all is well now and I hope this post helps someone else.

    Thanks hp for fast and wonderful customer service.

  • Can ping cRIO but unable to connect to the MAX

    I have a cRIO 9066 put in place on a local subnet. I think that all the software and drivers are correct. I have deployed my program and it works great except... When I add some optical converters of fibre in the mixture. Here is my system:

    PC--> cable ethernet--> ethernet switch-->--> cRIO ethernet cable * it works fine *.

    PC--> ethernet cable--> converter of fiber--> fiber--> ethernet switch (FPS)-->--> cRIO ethernet cable * unable to connect to MAX *.

    When I connect with ethernet cables all the way through, the ping time is<1ms ttl="" is="" 64.="" when="" i="" add="" the="" fiber="" converter,="" i="" can="" still="" ping="" the="" crio="" but="" ping="" time="" goes="" to="" ~250ms="" and="" ttl="" goes="" to="" 247.="" then="" max="" can't="" connect="" to="" the="" crio.="" is="" my="" connection="" speed="" too="" slow="" for="" max="" or="" the="" crio="" to="">

    My converter fiber and ethernet sfp module switch are all 1000 MB/full duplex. It is run only on a 10 m fiber. I tried several fiber optic cables. I tried the sfp in several locations. My sfp and the switch are both Advantech so I guess that they are compatible with each other. At this point, I plan to buy just a card PCIe fiber for my PC, but I thought I should check first with the experts.

    Thank you

    Hello

    There is a timeout OR max. The default value is 4000 Ms the reason why you are not able to detect the cRIO in NOR-MAX may be because the packages are damaged along the way. If you do not want to check this, you can always monitor the packets with WireShark with two different sets high. In this way, you can see if the packets are defined correctly or not.

    I hope this helps!

  • Wired laptop but unable to connect to the laptop wireless wireless PC can connect cable PC OK

    I have a wired network on whiich, I connected a WAP54G access point for my laptop wireless to children. They are never anything other that connect to the internet, so I never noticed this before. Now, I bought my own laptop and that you want to connect from my main computer but the laptop is not visible on the network. I then connected directly on the laptop to the network wired through an ethernet cable, and it was visible from the wired PC as you would expect. Back fi he returned invisible.

    Does anyone have ideas, what could cause this behavior?

    Thanks for all your comments

    Presumably using your XP or Vista!

    You need to change network settings into the laptop to allow remote connections according to the directives of the wired connection.

    You will also need to make changes to the false firewall XP/Vista has as well.

    FYI: The WAP54G has no way to filter all network traffic, so the question is not to the AP.

    Crossed troubleshooting but still unable to connect via the wireless network - no probs with other laptops.

    When going through "Toshiba assist" message arrives "this wireless network device is disabled.

    Please activate the device"- button wireless is activated with light yellow?

    any ideas?

    Are you sure that the laptop wireless switch is on?
    Look in the Device Manager. Maybe it's the wireless network card disabled. So activate it.

    Also try an update of the WLAN driver. You can find it on the Toshiba site:

  • Unable to connect to WIFI after upgrade windows 8.1

    Hello

    I fortunately was connection to my wifi at home last night before my HP Pavilion notebook updated to windows 8.1 g7. Now, I can only connect via ethernet cable.

    I called Microsoft Support and I was told that my wifi driver was outdated and must be reinstalled. I had a look at downloads available for the network drivers, but I'm not sure how to establish that that I need... There are 4 options.

    In the Device Manager > network adapters, it there was only one pilot who needed according to this update. The Realtek PCle FE Family controller. When I checked the updates here is said that it was updated successfully, but I am STILL unable to connect to the internet.

    Microsoft say it is a problem of HP, not them. Help, please.

    Thank you

    Hello

    My suggestion: using Device Manager to uninstall the Wireless driver and reboot the machine. Machine should say new hardware installed and find the good jerking for you OR you can download driver Realtek (wireless) from the above link and reinstall it.

    Kind regards.
