Registration of Wifi problem

During the execution of multiple programs, my computer made a noise like a fan of spray before restarting itself - it went through the cycle of update twice before allowing to connect you. When I did, I realized that it was no longer recording for wifi hotspots. I live in a dense area - I can still see other wifi on my list even if ours does not. The problem persists after restarting the computer.

Our modem and router our works fine, its only the laptop is no longer record the available wifi connections. I will note that in recent months, that he began to show popups for random programs that "has stopped working" - usually programs that were not even during running on the pc. One of the first was the Coolsense program. Looking at the events, the usual claim for programs no longer work was "lack of system resources. In addition, not all aspects of my computer seem to be saving all my material more. My still registers the Device Manager everything fine... other areas of the system do not.

My system is a HP Pavilion Notebook PC (ENERGY STAR) n210us-15 running Windows 8.1 (64-bit). It is no longer entirely saves my RAM or my processor. Which is an AMD A6 - 5200 APU with Radeon HD graphics card.

Is it possible to do a file repair? Or some other difficulty at home? Or do I need to ask of the HP system repairs / Best Buy [store bought]?

You could start with a few hardware-memory test, hard drive etc. using available diagnostic tools:

  • iPhone WiFi problem

    Hey, my iPhone 5s has a Wifi problem. I'll send text messages, but will not work iMessage. I can receive emails and receive phone calls. But, when I open my apps video/social media (Youtube, Amazon, Instagram, Snapchat, video etc.), the wifi does not work. Can someone tell me how to fix it? Thank you

    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).

  • 10 Windows WiFi problems

    Hello

    I have a Windows 10 partition on my MacBook Pro (Early 2015) retina. I use Windows on a regular basis, and recently, I have a lot of problems with my WiFi. Today, I completely lost my private WiFi connection and I can't solve this problem. I restarted my router several times and nothing has changed. I installed the Windows updates before - maybe that's the reason? Is it possible to reinstall the Boot Camp software? I currently have version 6.0. I can only find the versions 5.x on Apple's site. Or how can I fix this? In my device manager, the card network Broadcom 802.11ac is listed and even my router said: that the MBP is connected to WiFi. The network card is also says that I'm connected to the network, but access is limited (no internet access). WiFi works fine on my other devices like my iPhone 6 s. If you need anything else to know, feel free to ask.

    Thank you in advance.

    SOMEONE PLEASE HELP ME! REALLY ANNOYED WITH THIS PROBLEM

    Hello @jay05,

    Thank you for visiting the Forums from the HP Support! The forums are a great place where you can find solutions for your problems, with the help of the community!

    I came across your post about the WiFi problem and wanted to help!  I understand that you have found the DNS errors.

    First of all, try to review the steps offered by Community Member

    @Great-Christine-Tree:

    First of all, we have a step by step guide to guide you through the process of diagnosis here:
    Troubleshooting your wireless network and Internet access

    A second option is to try the following steps:
    Powercycle the network:
    1. turn off your laptop.
    2. unplug the power to your router.
    3. disconnect the power to your modem.
    4. wait at least 45 seconds.
    5 reconnect the modem and wait for it to come back online.
    6 plug in the router and wait for it to come back online.
    7. turn on your laptop and test your connection.

    Turn off the power to the adapter:
    1. open Device Manager. (Win Key + R > type devmgmt.msc > OK)
    2. expand the network adapters.
    3. right click on the Ethernet adapter / wireless, and then click Properties.
    4. click on the power management tab.
    5 remove the check mark next to allow the computer to turn off this device to save power.
    6. click on OK.
    7 test cycle.

    Reset the TCP/IP settings on your PC:
    1. go to your start screen/menu and type CMD.
    2. right-click on the command prompt icon and select run as administrator.
    3. in the window that opens type "netsh int ip reset resetlog.txt" without the quotes and press ENTER.
    4 restart your PC and test.

    It can also help to reset the winsock catalog:
    1. go to your start screen/menu and type CMD.
    2. right-click on the command prompt icon and select run as administrator.
    3. in the window that opens type "netsh winsock reset" without the quotes, and then press ENTER.
    4 restart your PC and test.

    Reinstall the NIC drivers:
    1. download the drivers from here , but do not run them again.
    2. go to your Start menu/screen and type Device Manager.
    3. expand network adapters.
    4. right click on the wireless adapter and choose uninstall.
    5 install the drivers downloaded in step 1.
    6. restart your PC and test.

    Test an ethernet connection:
    Explicit. Test if the problem persists on a wired connection to the adapter hardware troubleshooting wireless can be directed to the appropriate areas.

    Test another connection:
    Many people excluded their home network as a problem if another device working on the same network. Networking is not as simple as that. Each device interacts differently with your router or modem and it is impossible to exclude the settings for this device until the laptop has been tested on another network.

    If these steps do not resolve the problem, try this document published by Microsoft for network management issues: wired and wireless network problems. You can change the operating system with the drop-down list in the upper right of the document.

    Source: fixes Common for wireless connectivity problems.

    Hello

    I have laptop Lenovo P500 running under windows 10. Recently, I have wifi problem. The problem is that when the laptop is not connected to the charger wifi does not work. Sometimes, it is connected to the network, but shows a limited access, sometimes wifi is diseabled. Even after I troubleshoot it seems to work for a few minutes. but then, it's the same problem.

    Note: there is no problem with wifi when the laptop is connected to load it (works fine). The problem is that when the tower is not connected to the charger. For this reason, I always the laptop is connected to the charger.

    I don't know if this is related to your problem, but using the battery will cause the unit to run in a different way compared to the mode high performance when it is plugged. So you can try to change the power plan to high performance in battery mode. Of course, this will cause a more rapid evacuation of your battery.

  • WiFi problem after upgrade to Windows 10

    Greetings!

    I read a few posts on WiFi problems after the (improper) upgrade of Windows 10. I have a ThnkPad T530 which I've upgraded to Windows 10 Windows 7 in September (too late to roll back). Here's my question:

    I have three computers on my desk. This standard T530 running Windows 10, a ThnkPad E555 running Windows 7 and a Dell running Windows 8. I used all three last Friday. I installed Norton on all three Friday and everything went without a hitch. When I first started their return to the top of this morning, the two others came online as usual. The ThinkPad T530 connected by a router in the company, but has no access to the internet. I can connect to the hotspot on my phone and it connects fine. I tried to turn the WiFi connection and then turn it on again, restart, by killing and restarting the business connection, etc. Nothing changes.

    Help, please

    Try the following:

  • E-all-in-one printer WiFi problem 3520

    Product name: 3520 e-all-in-one printer

    WIFI problem ofline whenever we want go print

    I bought a HP 3520 printer e-all-in-one, cause it can print ussing WIFI. But I am very satisfied! Whenever I want to print, the printer go to ofline and is not able to perform the task of printing sent from my laptop. On my laptop, I have windows 8 and I installed the right driver. Yet he expect regeister once more my printer and install the driver all over again before finally seeks to print. For me with the amount that I have to print this is does not work!

    I'm regretting that a lot i let the salesperson talk to me by buying a Hewlett packerd. Because I have this printer now a little more than six months and already want to trow I have a very high roof. Previously I also had bad experience with a Hewlett Packerd printer!

    Hi idebont,

    If you haven't already done so, please run the PSDR.  Find and fix common printer problems using the tools of diagnosis HP for Windows?

    Make sure that the printer is connected directly to a wall outlet. (do not use a hub or a surge protector)

    This ensures that the printer is full on and can help this situation.

    We need to know if the printer or router is to lose the connection.

    You have a flashing wireless to the printer when you try to print from the computer or is the light solid?
    If it is flashing then the printer tries to find the network.
    If the light is solid, it is on the network. Try to print from a mobile device, if they are configured at the printer.

    Print a configuration page to see if the printer has a valid IP address.

    Printing a Network Setup Page.

    Type the IP address in the address bar of your web browser. (Internet Explorer)

    You can access the Web server integrated for the printer when the printer is in offline mode on the computer? (EWS)

    If you have a valid IP address and you can access the Web server integrated for the printer, then perhaps changed the IP address assigned to the printer to the router. So the origin of the computer does not find the printer. (setting up a static IP will solve this problem)

    Check the port showing on the computer to verify that it matches the IP address of the printer.

    Go to start, devices and printers, click right on the printer and on the left, click printer properties, select the ports tab.

    Click on configure port to display the IP address.

    If the IP address does not match, and then create a new port with the new IP address.

    Close the port to configure.

    Click Add Port, select the Port TCP/IP Standard, then New Port and follow the instructions in the wizard.
  • Intermittent WiFi problem after upgrade to Windows 10

    My acer aspire V3 - 571 has been intermittently lose WiFi for the last 2 days since Windows 10 Windows 7 Home Premium upgrade.

    The Aspire has:

    Driver Atheros wireless network adapt AR5BWB222 10.0.0.38 Wednesday 2/15/12

    So far, I have:

    1. in the properties Atheros AR5BWB222 Wireless Network Adapter, I unchecked the box in the tab property management who read allow the computer to turn off this device to save power.

    1B. Made sure flight mode was in the off position.

    1 c. Forget exactly where I did, but made certain settings in another? location have been set to "Maximum Performance".

    2. check that the firmware is updated on my network router, the value 2 of WPA - PSK (AES) security.

    3. search through many forums to read the responses of people upgrading Windows 10 WiFi issues - seems it is a widespread problem, although no one said that the WiFi signal loss was intermittent, as is my laptop. Shots of the Internet for my research also shows WiFi problems occurred in the past for installation of Windows 8. (So far have not come across mentions of WiFi problems for the latest installations of Windows 7).

    4. in exploring my laptop, I came across a page of Microsoft Updates - SEE ATTACHED. I was surprised to find that these updates go out quite frequently during the day. For example, 10 separate updates between 23:30 and 16:24 on August 1 and 18 separate updates between 12 h 06 at 15:57 on August 2.  Included in the record of updates for August 1 and August 2. I am aware that Microsoft uses my WiFi to download updates AUTOMATICALLY. It is possible that this intermittent intermittent interruptions of the WiFi update download?

    5. this afternoon, when the WiFi did not work for Windows 10. I reinstalled as a dual boot Ubuntu 14.04. I have had no trouble to connect to the WiFi for Ubuntu.

    Not yet:

    1. I haven't tried connecting the laptop via an Ethernet cable to my router during one of these WiFi failure.

    2. my ISP is a VOIP/Internet, using a Westell and a single Cisco router configuration. I have not taken into account if they can be a cause of the problem.

    3. I read on a forum that someone corrected their problem with WiFi connection by changing their setting include TKIP security router

    NOTE: I need to put Windows screenshot attachment 10 updates in a response email separate to this post as this post does not accept the attachment.

    Would appreciate your comments and suggestions. Thanks in advance.

    I'll probably also put this on a Windows 10 forum elsewhere.

    Hello!

    FYI, this has worked for me, finally a solution!

    The strangest thing - I have uninstalled the driver Atheros. Do NOT reinstall it. After uninstalling the driver Atheros, a right screen Windows 10 panel immediately appeared style - either on advice of Panel or in the page settings of WiFi, was asleep, can't remember which - that contains an entry box marked my wifi password. I entered the password and boom, the wifi worked. He has been since.

    Once again thank you. Mark resolved.

  • WIFI problem with router WAG120N

    Hello
    I have a router linksys WAG120N upgrade 1.00.16
    and I have wifi problems that while I use wifi on my laptop or mobile then disconnected wifi (wifi on green router, but I can't connect) until I have restart the router
    Can you help me?
    Please, I beg you!

    It could be the firmware is damaged. Firstly, what you can do is set a channel fix (1, 6, 9 or 11). Customize settings wireless advanced: tag set to 50, interval threshold of Fragmentation 2306 & 2307 RTS threshold. If this does not help, make sure you reflash the firmware, reset the router and reconfigure.

  • Meeting 10-7040, Wifi problem

    My new tablet, place 10 7040, has wifi problem. It hardly captures disconnection and sometimes wifi signal can't even in suspended or sleep mode but use it. I found that it is almost impossible to discover any access point signal when it is behind a wall or a door and only possible to connect to the internet when she positioned close to an access point with no barrier. Even if it has been connected, antenna guage remains very low, and sometimes it is disconnected and could not reconnect for a while...

    any solution or the tent will be welcomed.

    That's why both of us.  Today called tech spt and they immediately told me to call customer service and request a replacement. I had the initial installation to stand right next to my access point.

  • Smartphones blackBerry Torch 9800 WiFi problems

    Just bought a 'unlocked' Torch 9800 from Amazon.  We are having a problem with the game facing upwards.  The WiFi signal is detected by the device, but we cannot send or receive e-mails.  When you log on to the browser, we can not go to the line, as it is said that it has turned on WiFi but not coverage.  I have contacted my provider "Three" and they say that, to their end, everything looks good to go.  My previous phone is a Curve 9300 that works very well, I'll have to use my old phone and it is send and receive e-mails very well with good coverage.  The abandonment of the cover guard torch its all very frustrating.

    We arrived at the conclusion that the problem is the phone itself, it has not been unlocked properly or we are missing something in the game upward.  If someone had a similar problem or you can shed some light on what we can hurt?

    Hello and welcome to the community!

    If you can use on the 9800, phone services via 3, then it's unlocked properly... but you can check here:

    Any BB can be used on any carrier that is running the same radio frequencies that the BB is capable of (and I have no idea if your in are such). But, to bring you a BB on a carrier network that they don't sell, there are several obstacles to overcome:

    (1) the carrier must say 'yes' to the fact... they are owners of their network and have every right to say what devices will be allowed to connect to it. If they say 'no', then it's the end of it.

    (2) you must be sure that your BB is properly unlocked since its origin manufactured for carrier... see this thread useful for more details:

    (3) you must get all of your voices works on the carrier, before you even try anything on data level services

    (4) you must be a subscriber of the carrier, a plan of sufficient data to enable BB exclusive services that you wish to

    5 (a) if the carrier directly supports your specific model BB, then you can proceed to the registration of the BB on their network, generating adequate for your BB service book delivery and treatment of the function. Since you didn't say that 3 you are on, I can't check to see if they support the 9800 or not... we do it, the other does not. But you can post via the official download portal:

    If your carrier lists the 9800 in their portal, then they take over the it and you should be good to use it on their network.

    5 (b) but, if the carrier does not directly your BB-specific model number, then the challenges are much more that most of the carrier's systems will deliver, for BB, the service books required to enable BB exclusive data services, even if you have subscribed to them.

    So, based on this, your BB may or may not ever any function on this carrier network. It can be quite difficult to achieve, especially if 5 b applies. Then take a look at this and decide how you want to move forward. Most people end up just buying a new BB if 5b applies.

    If 5A applies, then I suggest the following, in order, even if they seem redundant to what you have already tried (steps 1 and 2, each should result in a message to your BB to come...) Please wait for this before moving on to the next step):

    (1) registry HRT

    • KB00510 How to register a BlackBerry smartphone with wireless network
    • Please wait a 'registration' message reach your Messages application

    (2) Service reference books

    • KB02830 Send the directories for the BlackBerry Internet Service
    • Please wait "the Activation' Messages, one per already configured e-mail account, arrive in your Messages. If you have not already configured email accounts, please wait 1 hour.

    (3) restart to take batt

    • Each time a random strange behavior or slow creeps, the first thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

    I hope that will move things again for you! If this isn't the case, then you must keep workign with your mobile service provider as is their network with which your BB is unable to communicate, and only they can look "behind the scenes", as well as degenerating into RIM if necessary.

    Good luck and let us know!
