• 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.

  Hello;

  Let me welcome you on the HP forums!

  I read your post on your disconnect WiFi the day after and wanted to help.

  The most common cause is of power options.  Open Device Manager (in Control Panel), scroll to network adapters, right click on the WiFi adapter and select Properties. Go to the power management tab, and uncheck the option that says: "Allow the computer to turn off this device to save power", click OK.

  Restart the PC.  If that fix it, you're done.

  If not, then read these additional troubleshooting tips WiFi: HP PC - wireless network and Internet troubleshooting

  Good luck

• Firewall cannot power on. Unable to connect to WiFi.

  I have a Samsung PC with Windows 7 Home Premium. I have several problems with it. First of all, I have constantly to the little flag in the bottom right of my screen telling me that there are 5 questions with my PC, but above all it tells me that my firewall is disabled. Obviously, I tried turning on, but after asking me only one to turn on (AVG, windows,...) and then ask the admin. permission, nothing happens. The little note in the corner is still there, and nothing has changed.

  Second thing is, I can't connect to my WIFI at home with my laptop. I have 3 roommates, and they're all perfectly fine internet. When I try to connect, it tells me that it is connect but with no access to the internet and then a small window appears in the lower right corner, say that there might be additional information needed. After trying just about everything, the only 'useful' thing, I found was troubleshoot tells me there could be a problem with my driver for wireless network connectivity. The adapter is an Atheros AR9285 Wireless Network Adapter. When I try to disable and re-enable the driver, nothing happens, and I don't really want to uninstall and re install since I think that might just make things worse.
  Can anyone help?

  Hi Zornig,

  Thanks for posting on this forum. If I understand correctly, you are facing 2 problems on your computer. First of all, you are unable to turn on the firewall. Second, you can not connect to WiFi with your laptop. Hope I understood the issues.

  Zornig, if you have more than one anti-virus or firewall applications on the computer, this problem may occur. It is recommended that you have only installed on the computer so try to uninstall one of them and check.

  Due to WiFi, try the methods provided.

  Method 1:

  Run the network troubleshooter, and check. Check out the link and follow the steps.

  Network convenience stores

  http://Windows.Microsoft.com/en-us/Windows7/open-networking-troubleshooters

  You can use logs of the events of the resolution of network problems and try to solve the problem. Check out the link.

  Use Network Troubleshooter event logs to solve network problems

  http://Windows.Microsoft.com/en-us/Windows7/use-Network-Troubleshooter-event-logs-to-solve-network-problems

  Method 2:

  You can reinstall or update the NIC drivers. This can be done without harming the computer anyway. Check out the link and follow the steps to install the drivers for the device.

• Unable to connect to Wifi. No guest password when connecting

  Original title: no guest LAN password for my home network wifi unable to connect wireless, why am I not even invited to enter my password?

  I am trying to connect my two PCs to my wifi at home.  It has a requirement for password and my Apple devices can connect properly. I just don't get no guest password LAN and it fails to connect. PCs are fairly new and since the change of the password today, they have bee unable to connect.

  Matt,

  Please check the IP addresses defined on each of the computers.

  -Open the command prompt amd type ipconfig/all and press ENTER.

  Also try to ping the router from the computer and check if there is a good connection.

  - Ping 192.168.1.1 (if 192.168.1.1 is defined as the IP address of the router).

  If computers have starting with 169.xxx.xxx.xxx IP addresses then you will not be able to connect to the router wireless and the Internet. This address is called APIPA.

  You will have to perhaps release IP addresses and make sure.

  -In the command prompt, type the following command and press ENTER.

  ipconfig/release

  ipconfig/flushdns

  ipconfig / renew

  Please let us know the IP addresses defined on each computer and also the IP address it of the router.

• I think that I broke the internet. Unable to connect via WiFi

  I don't know what happened, but for some reason, my laptop does not connect to my home network.  I tried to plug directly into the router with no luck.  I also tried to download the new drivers w / laptop from my friend to a USB key, but that was of no use.

  Just to let you know:

  It is an equipped 64 Vista DV4-1140go.

  I am able to connect to my network wirelessly with my BlackBerry and laptop my girlfriend via wifi.

  I am also able to connect to internet with Xbox plugged into the modem.

  Thanks for any help.

  Well, it turns out it was Norton all along. I thought that I had uninstalled completely until I came across this link Norton Removal Tool.

  I then decided to test McAfee because Comcast (isp) offered free of charge.  Well, today they no longer offer McAfee. Instead, there is a link that says "with McAfee? Time to upgrade to Norton free with Comcast"LoL FML

• New laptop unable to connect to the Internet. Help

  Hello world.
  I just got a new computer hp laptop but it is impossible to connect to the Internet. Whenever I tried to connect it to my server, it says unable to connect. I tried all the possibilities I could think. I also had a printer wireless and chrome cast which is unable to connect as well, but my cell phone, laptop and portable older is able to connect again. Help, please!

  The brand of the router should not make a difference. You know for sure that the router is working properly? Can you connect other devices to it and make it work properly? It may well be that the router is the question. If you hire someone like AT & T router, you may need to call them, there may be a necessary service that only they can fix. Go ahead and give me the model number of the router, will see if I can find something...

  Have you gotten to the point where you entered the security keys in your devices? If so, it reduces some of what we would have to do.

  Try resetting your devices. Go ahead and turn off your laptop. Then unplug your router for about 30 or more. Use it to back in wait for all lights to turn green. Once your router is ready, start your laptop up. Refreshing devices as is sometimes necessary after making any changes to the network settings.

  Sorry for all the running around... network problems can sometimes be difficult to understand.
