HP 19-2114 lose computer cable network connection

I have two nine brand computers 19-2114 running Windows 8.1 64-bit. Both behave the same way.

When I boot, usually, I'll be able to connect to my network (via ethernet cable) for 15-30 minutes, then the connection will be deleted. Reboot usually restores the connection, but even once it will be dropped shortly after.

I use ping to the prompt for the simplest test to know if I have an internet connection. If the ping does not work, or no Internet Explorer.

Other computer models, when it is connected to the network via the same cables, have no problem.

I have not loaded any software or data. I tried system restore to bring the machine to factory settings, but it does not help. I tried to reload some network drivers as suggested on the HP site, but that made no difference.

Finally... on these new computers I changed the DNS settings. They had been "obtain automatically", but I typed in many explicit (for developers of Google public DNS) for IPv4 and IPv6. This works.

Mystery: our old computers still work very well with the 'get it automatically' setting.

  • I lose the internet connection randomly but never lose my wireless network connection.

    I use a hp pavilion dv9500 with 64-bit vista sp2 and built in a wireless adapter that will fall randomly my internet wireless connection, but maintains my wireless network connection with an excellent signal strength.

    My (non-permanent) fixed
    I know how to reconnect to the internet, but it forces me to diagnose a repair my connection. It then displays "cannot connect to Server primary dns (75.75.75.75)"after which it gives "things to try" who never work and a button 'Reset the ip address' that I click. " repair bar will fill up to half way and go to a new screen solution that shows more 'solutions' and a "reset wireless adapter" button which I click. the remedy bar will fill and then display windows can not solve the problem and go for help. I then manually disconnect from the wireless network and my computer will automatically reconnect to the network and to the internet. It takes about five minutes to fix, but it happens so often that it is getting boring. The process will not work if I only to reset the ip address and then disconnect from the network, only to reset the wireless adapter and then disconnect, or just disconnect from the network and reconnect. I have to reset the ip address and the wireless adapter and then disconnect from the network.

    The internet connection will tend to disconnect when I watch a lot of youtube videos, when I download large files like a game on steam, or just just randomly when I use it. I'll use it for a long time and he can't let it go, but sometimes it will go down to ten minutes after I had just reconnected in a drop-down list. It happens randomly without another warning that download time will increase from 2 mb to 50 k in two seconds all about or stop the loading of a youtube video when I look at it.
    I searched everywhere for an answer, but it's as if it were a new problem for all humanity or just im the only person who does not know how to solve this problem, because there are no forums or FAQ not related to my problem. It is not so much a serious problem such as an irritating problem that appears at inconvenient times or when I just want to relax and watch a video. It takes some time to reconnect and even though I know how it would be better if my connection would just stay connected to the internet at any time.
    I have no idea what the problem could be that whenever I have find I never get related problems. all advice or solution would be great.
    I also share this modem with other three commonly used computers: a wired office and two other laptops that the two are connected wirelessly. both other laptops do not have the same problem as mine. My router is a linksys e3000 wireless router.

  • On my old computer wireless network connection disappeared. When I try to update or roll back, nothing happens.

    I just wrote all of the above details in the section title - I can connect to the internet with an ethernet cable, but not with my wireless connection (e.g. in McDonald's restaurants). I bought a new computer with Windows 7 and installed a dlink on this wireless router.  It is then the connection Wireless on my old laptop family disappeared.

    It is not entirely because think that the hardware is failing.  ;-)

    It seems as if you have uninstalled the Intel wireless controls in Add or remove programs and the wired connection disappeared, can you have uninstalled something else than just wireless stuff.

    This laptop has the Wired Intel Pro/100 VE network adapter - easy enough to uninstall something inadvertently to another 'Intel '. ;-)  (The link for this driver is included here).

  • WRT54GS - no internet connection is detected and yet my computer cable to connect to internet through router

    I had my router for a little over a year. I am connected to a wild blue satellite modem. He has worked without problem for a year.  Now, he claims not to detect an internet connection, even if the computer connected to the router has no problem connecting to the internet. I just can't connect wireless to the internet because the router thinks that there is no internet connection. I have reset several times, turned on and off the power to the modem, followed all the troubleshooting instructions. All the lights on the modem and the router. I need to replace the router, or I would encounter the same problems with a new?

    If you use the update 1.6 LELA LELA 3.0 and your problem will be solved.

  • Internet connection Windows 7 loses, but not network connection - suite.

    Does anyone have a solution for this? Everything I have discovered that restarts 3 first servises whose name starts:... network solves this temporary. This only happens on windows 7 64.

    According to what I have read this problem has been solved because I haven't lived it to buy the new laptop in May 2010 until about last month. So yesterday, I removed all updates of November 3, and it does not occur until now. It is too short to say that these updates are so lost cause http connectivity, but I'll post if it won't happen again. Right now, I disable windows update. If it works fine without them I won't try and change.

  • Wireless network connection does not

    I can't access a wireless connection with my computer wireless network connection. The icon in the bottom right of the screen shows a red X and says 'not connected wireless network connection. The wireless on my keyboard button does not illuminate

    I tried to change the channel on the new ADSL2 wireless router and refreshed looking for wireless connections, but still not found connections. I have not used a wireless router before and never used a wireless connection with this computer so I don't know if the wireless card works or not, if the properties of the wireless adapter indicate that it works. Is there a way to check if the computer's wireless card is running or connected and if not, how can it be connected? Thank you

    I finally understood by trial and error, why I was unable to connect wireless to a modem, that you sent me. In my control panel, I found that the properties of HP Wireless Assistant had "Hide status icon" checked, so I checked it and the icon came in the bottom right of my screen. I left then clicked that icon and it showed the wireless and bluetooth was OFF so I went in and it now works.

    Why HP support could not help me in what I don't know, I just got the race!

    Hope this helps others with similar problems.

  • locked Windows XP network connections

    I was struggling for the last 2 weeks with my ip address does not change do not. I've been in contact with my ISP technology support and we found the network connections is locked. When I click on the Connect box icon nothing happens. When I right click the icon and select the State that nothing happens. I can't access one of the parameters. so I uninstalled and reinstalled it and its doing the same thing. I have 2 computers hooked up to the same modem and they another computer's network connections works when I click on the link, it opens a connection status window box. so, how can I unlock or whatever to make it work again? I tried everything I can think of. I have internet access and can get online.

    This problem was caused by a Trojan virus. It spread across my operating system. I had to use a hard drive cleaner and completely erase the hard drive. That took five days to do. When he finally finished, I reinstalled Windows XP. My ISP Bright House gave me another modem, with its own security and firewall so that it will not happen again.

    Thank you very much for the help.

  • TimeCapsule loses network connection

    I have a TimeCapsule (new version of turn 2014) and I noticed that my backups are not being every hour. Utility app showed 'device not found' on the network.  I restarted the time capsule - it connects to the network successfully for about 3 minutes and then "Device Not Found".  I restarted my TimeWarner cable modem then restarted TC even question.  My wifi router is the TimeWarner modem and I have 60MB of speed that I'm guaranteed up to 50MB, so all right from the internet side.

    I did a soft reset... same question.  I did a hard reset and used the previous settings - same issue (3 minutes network, and then click device not found a few moments later).  I guess I can do a default network but since absolutely no changes to the network settings have work probably months (7 + months) I don't see why this would happen.  I don't want to lose my entire backup (s) risk is... I have no other way to save my December 2015 MBP.  * Funny, it is the TC network shows, if I hit him "save now" finds TC but TC for 3 minutes then turns off network; However, the backup actually occurs successfully. But will not back up again until I restart then the TC on the network these 2-3 minutes before losing the connection.  Help.

    I have a MBP 15 mid-2015 "and capital El v10.11.6.  My TC etc are all up to date on the versions of software too!

    Many users have posted on the forum with the same number of "Device not found" in the last days. Looks like almost every new post is about it. This is one of a few minutes there are, for example:

    TimeCapsule loses network connection

    Rumor has it that the 10.11.6 recent update is part or all of the problem, according to the opinion.

    The "fix" of the day is to disable Back to My Mac in AirPort Utility, that seems to work for users who have helped with my Mac. Of course, you lose functionality when you do this.

    No solution yet for users who do not use Back to My Mac, because they cannot turn off something they did not.

    Apple is silent, not so much we can do until Apple recognizes that there is a problem (which they are not since yesterday when I spoke to them).

    Stay tuned.

  • Pavilion dv6-7135nr: loss of network connectivity and wireless after upgrade to Windows 10 cable

    After the upgrade to Windows 10, I lose network connectivity after a restart of the computer.

    The operating system fails to load drivers Broadcom 4313 n. The driver date is May 8 202. The reason code is 31 on failure to load the drivers.

    I returned to Windows 7 and migrated to Windows 10 several times with the same result. I tried to upgrade on the Broadcom drivers, but Windows says they are up-to-date.

    I also see that the Realtek PCIe GBE Family Controller is having the same problem.

    I think it's a driver problem, but cannot find the correct set of drivers.

    Any help would be very useful. I have just re-upgrade to Windows 10 and have network connectivity.

    During this process, I have disabled the firewall, but that did not help. However, I noticed 'tweaks' accessed via the tab 'Advanced' in 'Microsoft Firewall' which looked like, they must be checked in order to access the internet. I checked these and reintroduced the firewall. After I got things working, I unchecked them and things still worked so I obviously don't understand what these parameters.

    The solution:

    (1) I have to go straight from the modem cable to the computer. I can't have a cable modem, router wireless, computer, even if using hard wire, and even if this same configuration works with another computer. Also, I can't use a cable length to go from modem to the computer. So, it seems to have had a problem of cable length. Power problem? Only connected to this computer devices are the mouse, the keyboard and the Ethernet. Would not this be fixed with an upgrade of the power supply? Or is it due to the quality of the Ethernet hardware on the motherboard? It's a Dell Vostro 200.

    (2) in back and forth between configurations while following the problem, you must think to unplug the modem to reset between each configuration. You may have stumbled upon the solution, otherwise he's not shot. Also, I unplugged the cable from the modem when you reset data cable - do not know if it was necessary. I wanted to limit the degrees of freedom that I had a lot, as it was.

  • HP LaserJet M1522nf begins to lose the network connection

    Hello! I have HP LaserJet M1522nf and I use it for about 1 year maybe, but since last week, he begins to lose the network connection (ping failed, web interface does not work too). To be correct, the printer is connected directly to the network through an ethernet cable, and the cable is perfectly fine. His work when you turn it on and for the next 5 to 15 minutes, but after that it lost connection (tasks start fails).

    I really like using little aid, some perhaps of advice. Any suggestions?

    Hard reset the router to factory settings and reconfigure your settings.  Pass the cable to a different port on the router.  You said that the cable was good... change anyway.  Try now.
