My Pavilion G7 Suddenly Cannot Recognize WiFi Signal For Second Time In A Year

Hi All,
My Pavilion is about two years old and the
motherboard was replaced by HP while under
warranty. 
For the second time in about nine months the notebook suddenly cannot recognize my router's 
WiFi signal. This time if I do a system recovery I will have to reinstall 50 apps! I am trying to avoid this if possible. I understand that changing the bios settings may fix wifi issue but no idea how this step will affect (delete/save) files. Upgraded from WIN7 to 8 to 8.1. Please help. Thanks so much.
This question was solved.

Hi @actionrob 
Welcome to the HP Community.  I hope you enjoy your experience with us.  To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding the problems connecting to your router.  I will be happy to help you with that.  I will need to know what the product number is for your notebook as there are a number of models in the g7 series.  Try the troubleshooting steps in this HP document Troubleshooting Wireless Network and Internet.
Here are some generic steps that you can try as well:
Power cycle the network: (Do this even if you have other devices that work properly with the router as it will interact with each piece of hardware differently)
1. Shut down your notebook.
2. Unplug the power to your router.
3. Unplug the power to your modem.
4. Wait at least 45 seconds.
5. Plug in 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 notebook, and test your connection.
Reset the TCP/IP settings:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.
Reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh winsock reset" without quotes, and press enter.
4. Restart your PC and test.

    Theoretically yes. It will really depend on your situation. Please review the following Apple Support article to understand what is possible with the AirPort base stations and post back with any questions or help in setting up your extended network.

  • ITunes cannot recognize this iPod at this time....

    My Shuffle 2G lost power yesterday and when I connected it to my Mac mini to recharge, the light flashed a few times before getting the error prompt "iTunes cannot recognize this iPod at this time." The prompt instructs the use of the reset utility, which I ran repeatedly to no avail. I've tried all the rebooting, restarting iTunes, switching USB ports, etc. with the same error message each time.
    The power indicator is no longer responding at all following the first time that I connected it yesterday. Is my Shuffle completely fried? I've only had it a year and it was hardly ever used during that duration. Help!

    The exact same thing just happened to my 2nd Gen shuffle. It stopped playing due to low battery charge, then when i tried to connect it ti iTunes, it said it 'could not recognize iPod at this time" and to use the reset utikity. I have now ran the reset utility a few times....but there is no change.
    I would really appreciate some help in solving this issue.......

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)

  • Have one WiFi signal into the apartment for my Air, and another wifi signal for my 5c phone plan. Both from the same provider. Expensive. Is there a way to 'combine' WiFi signals so I pay only for one, but can get on the Internet with my Air?

    Have one WiFi signal into the apartment for my Air, and another wifi signal for my 5c phone plan. Both from the same provider. Expensive. Is there a way to 'combine' WiFi signals so I pay only for one, but can get on the Internet with my Air?

    Roamingnome, thanks for your response. Although I have been a Bell (Canada) customer for my WiFi signal for years, the 5c and its necessary mobility plan, is very recent. Some years ago, Bell supplied its own ‘router’ for my computer, and claimed that it was possible to get their WiFi signal only with the router they supplied. When I recently received the 5c, I wondered if the plan it requires, which is within the much wider, overall Bell zone, could be used somehow to get my Air online - some sort of tethering? - that allows me to give up the Air WiFi service and router all together, but still get the Air connected. Here in Canada, Bell Mobility and other Bell services are very separate. Any suggestions appreciated.

  • HT4628 My ipad and iphone connect and recognize wifi signal, but my mac pro running 10.6.8 does not  recognize or list the wiifi signal as option, any ideas?

    Hi,
    In Austria, iphone and ipad "see" and connect to wifi signal no problem but mac pro in same room will not even allow me to choose the same wifi signal.  It seems almost blocked.  Havectried everything it seems by restarting, deleting preferred accoints, etc.  software is updated but running osx 10.6.8
    Thanks for any help!

    Try the basics first:
       Change your router channel number.  Most times this works & is all you have to do.
    Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.

  • Airport Extreme (5 Gen) suddenly very weak Wifi signal

    Hello, everyone.  I have a 5th generation Airport Extreme that was working fine until a few days ago.  My power had gone out, and since then I am getting a very weak Wifi signal.  The network still appears and connects on all of my devices.  However, it is dreadfully slow (0.3 MB/s per Speedtest.net), whereas before it was 50 MB/s.  I have tried resetting to factory settings and opening up the option to 5GHz.  The 5 GHz wireless network works just fine on my iMac.  It doesn't show up as an option on my iPhone, though, and that's what's really bugging me.
    I'm wondering if anyone else has had this problem and can help me out.  Of course, my phone support expired a few months ago and now they want $19 for a tech call.  Any help here would be greatly appreciated.
    Thanks!

    Reset to factory again.
    Setup again using all short names, no spaces and pure alphanumeric. If you were doing this make sure you use different names. Empty all the old names from the clients so they start over with fresh clean setup for wifi.
    Use a different name for 5ghz.
    Use fixed channels.. try 1, 6, 11 for 2.4ghz and try 36, and 150 for 5ghz.. around about.. exact channel is not such a big thing for 5ghz.
    Check the link speed and make sure it is full speed if you are in the same room as the AE.
    Test by copying a file on the local lan.. rather than testing to internet which could be a totally unrelated issue.
    Test by using ethernet only on a computer plugged into the AE to see if the internet link has gone slow.

  • Cannot find WiFi driver for E-15 0319-3SU

    Hi,
    I've tried to locate the WiFi driver for an E-15 0319-3SU without sucess.  I tried all of the available drivers on the site according to the model I have and can't seem to get one to work.  I have reaffirmed that the driver is showing as missing in Device Manager.  I'm using Win7 x64.  Sadly Lenovo System Update for whatever reason doesn't recognize the missing driver and won't update it either, so I'm up a creek!
    I reformatted one of these a while ago and recall having a lot of trouble locating the correct driver.  I had saved the driver but have since overwritten it so I can't use it.  Can someone please help?!
    Thanks!

    Hi Loopdokter,
    Welcome to Lenovo Community!

  • I need to boost my wifi signal from my Time Machine.  What is that device called.  it plugs into the wall.

    I have an apple booser that plugs into the walll to help boost my wifi signal.  I went and purchased another one and they sold me the airport express and it does not have the wall plugin.  What is it that I need to exchange it for?  You would have thought they would have sold me the right thing!

    Does the old still a good product?
    Yes
    So, this is all there is all there is available to boost my signal in hard to reach areas with Apple devices?
    You could try an AirPort Extreme instead of an AirPort Express. The issue may be size. Imagine eight of your A1392 models all stacked on top of each other.  It does have a better antenna setup, but I doubt that you would notice much improvement in your situation.

  • Wifi works for short time

    Dear readers,
    Since a few weeks my wifi / airport on my Macbook stops working after a few minutes. I can temporarily fix this problem by turning off and on the Airport function, but after a few minutes it kicks me out again.
    Other details:
    Cable works fine.
    Full wifi bars at all time.
    Not a router issue. Other devices work fine and problem occurs both at home and on work.
    I recently updated to Mountain Lion, problems started to occur around this time. (not 100% sure)
    Problem still occurs after downgrade from Mountain Lion 10.8.3 to Snow Leopard 10.6.8.
    Examples: (I have the feeling that has something to do with bandwidth usage)
    Browsing the web is possible for about 5 minutes.
    Youtube video stops loading after 2 minutes.
    Any kind of download works for 30 seconds.
    What I tried:
    Simple reboot
    Software downgrade
    Creating a new network location
    Manual IP
    Change DNS server
    Change MTU
    Some reset by pressing cmd/ctrl/shift/power during startup
    I know that i'm not the only one who is having this problem. But i really hope that this (extra) post will get some attention from Apple.

  • Cannot recognize wifi networks

    My laptop is hardwired to a wi-fi network and works fine. However, when I take it elsewhere, it does not recognize any wireless networks - including the hard-wired one -- other devises and computers recognize it fine, so it must be the laptop. If anyone could direct me to what to do, I'd appreciate it.

    Go to Solution.

    You cannot hardwire to a wifi network, only the ethernet can be hardwired. If you cannot connect to any wifi your adapter may be turned off or it's possible you don't have wifi installed. Is the wifi icon lit?  switch on? press FN+F5 and see if it reports as being on.

  • Following installation of OSX 10.8, the program cannot recognize the disk containing my Time Machine back-up

    I made a Time Machine backup of my hard disk. before erasing the latter and installing Mac OS X 10.8. But now, the program is unable to recognize the disk containing my backup, and therefore I cannot use the Migration Assistant to recover my data. Is there a solution to this problem?
    However, Migration Assistant was able to recognize my backup disk, before it was unlocked, but not after...
    Thanks

    nothing here helped me. there is obviously a bug in 10.8.2. Due to other issues, I wanted to install a clean copy (not upgraded) of 10.8.2.
    On a MBP running 10.8.2, I made a full Time Machine backup.
    I erased the internal HD on the laptop.
    I installed 10.8.2 from the App Store installer
    When the installer rebooted, the install process continues, BUT
    During installation, when asked to select a disc for restore, the installer spins but never sees the time machine backup.
    I can see this disc and drag files from it when plugged into another computer (or when booting the MBP from an external HD) but the OS X installer process never recognizes my Time Machine hard drive and never progresses past the select disk for restore process (the disk NEVER appears).
    The disc (FW) works fine plugged into other computers and worked fine before reinstalling 10.8.2. on a fully formatted hard drive.
    Time Machine is WORTHLESS.
    This advice from Apple is useless: "Open Time Machine preferences and reselect your backup disk. If you erased your backup disk and began having trouble, reselecting it may fix the problem." - how do you do this when you're restoring data to an erased HD?!?!?!

  • My ipod touch 5th generation keeps wifi signal for 10-30 minutes and then just stops working.

         I've had my ipod for about a month now and it worked fine up until this week.
    This week I noticed probelms with the wifi. I would be just on facebook or browsing the web and the wifi would just stop working. Every time I turned wifi off and the on again it would give me about 5-10 more minutes of wifi before I had to do it again. I've never expeiranced this with my other 4th generation or 3rd generation ipod touches. The wifi itself is not the probelm because it works just fine on my laptop. Today I updated my software and the probelm was not resolved.
         I need help sould I got to the Apple store and have them check it out?

    Does the iPod have the problem with other networks?
    Do other devices work OK?
    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router

  • I suddenly cannot startup Captivate 4 for reason Flash Player for Internet Explorer not installed or older version, but I have verified that Flash Player 16,0,0,235 is installed. Please help.

    Hi,
    I haven't used my Adobe Captivate 4 for a bit, but when I try to start it up, I get the following message:
    "The Flash Player for Microsoft Internet Explorer, is not installed or its an older version.
    You will automatically be redirected to the Adobe website to download the latest Flash Player.
    Please note that the Adobe Captivate cannot be used until the Flash Player is installed."
    Even if I click the OK button and reinstall the Flash Player, I still get the same message, when I try to startup Captivate.
    I have verified that I'm running Flash player 16,0,0,235, which is supposed to be the latest version.
    I'm running Windows 7 and Internet Explorer 11.
    Please help.

    The problem is that your version of Captivate 4 needs to be updated with a patch that Adobe used to supply.  (I don't have a link anymore to it.)
    Captivate 4 was unable to recognise Flash Player versions beyond a certain number.  It gives you a misleading  error message that makes it look like you have the wrong version of Flash Player.  But the real problem is that Captivate needs to be patched to recognise the latest FP versions.
    I'm hoping that someone from the Adobe Captivate team will chime in here and give us another link to download the patch.  Otherwise, you really might be forced to upgrade to a newer version of Cp.  However, if your current projects are being built in Cp4, your next issue will be that if you purchase Cp8 it will NOT be able to upgrade your Cp4 projects.  You'd need to download a trial version of Cp5 or 5.5, and do a two-step upgrade.

  • Suddenly cannot change the calendar for an event in iCal?

    When I creart new events, they now automatically are asigned to the top calendar group (as listed on the left side of the iCal screen).  When I try to edit the event and asign it to a different calendar, the menu only shows the calendar groups, all in grey, not the individual calendars. 
    When I go to preferences to investigate what's going on, I only see the calendar groups, all in grey, not the individual calendars.
    When I click on the "+" sign in the top-left corner, same problem, only the calendar groups appear, all in grey.
    Why can I suddenly not access these calendars when editing an event?  Why do they stop showing up in the editing menus? 
    The calendar still show up in the list menu on the left. I still can add new calendars and new calendars groups.  The problem occurs when I try to assign an event to a specific different calendar.

    Saw your post Beth over on my thread but I thought I would respond on this one since we're all here.
    Hi y'all (^_^)
    Sorry to meet under such horrid circumstances, but it's nice to know that I'm not the only one.
    I've found out a few things that didn't work so here's the list to save you both some heartache.
    No type of re-install fixes is. Not a partial reinstall of the OS where you keep your data or a full wipe.
    Checking your permissions or scanning the disk for errors doesn't work either. Creating a dummy user account to see if the problem ports over is a waist of time. If you don't have free support on your machine don't spend money on opening a ticket.
    The problem is specific to the Mountain Lion release 10.8.3. The only fix that I have found while I wait on apple is to regress back to 10.8.1 (18.8.2 has the issue also) . . . reverting isn't hard to do with this nifty program I found but nearly impossible for me as I purchased my iMac in February of this year and the firmware came with 10.8.3 in the recovery partition. I've been scowering the net looking for anyone with a 10.8.1 full install dmg (not the update) but everyone either thinks I'm pirating software or doing something impossible so needless to say I'm still running 10.8.3
    But all is not as bad off as we think. The problem is only with Calendar (or contacts, whichever place originated the problem as I have found the majority of people on the net who have encountered this did so while in the Contacts program not Calendar). This is a good thing! Because since the problem is unique to the software of origin (Calendar for us) that means we can still use use Calendar and the cross-program functions of Calendar (like creating an even from mail or inviting someone from your contacts) as if nothing is wrong. All programs that read event or calendar files work just great, only Calendar is having the issue. In other words, keep using Calendar like there isn't a problem.
    This is a hard pill for me to swallow because I see that there is still a problem and I am itching to fix it. My obsession is only causing me to drink. I have tested this theory by creating a whole new schematic on iCal where I have 6 new Calendar groups all with at least 3 calendars in it and multiple events. (I'm a small business so they're not just dummy events). The great news is everything works like it should as long as I take precautions.
    Here are those precautions:
    1 - When creating a new event MAKE SURE YOU ARE IN THE CALENDAR YOU WANT THAT EVEN TO BE IN since you won't be able to use the drop down and choose later because it is greyed out for us.
    2 - If you run into this loop where you can't save changes to an event (happened to me a few times when the problem first materilized) just pop the calendar that even is inside to the base calendar list. In other words, take the calendar out of the group, make your changes, then click and drag it back into the group. Even if the event is recurring everything will be fine. Groups only alter the hierarchy of how iCal stores and displays the files, not the files themselves which is why other programs aren't having a problem reading them.
    After I made my slew of new groups I tried a few things out to make sure everything was actually still working and it all came out perfect. You can still publish, sync to google, or iPhone, or android and things will display just as you expect them too. Reminders even worked. The problem is ONLY inside iCal and even then only when trying to use that drop down menu.
    Long story short, if you can deal with knowing in your gut that things are f.u.b.a.r but keep going about using iCal as if it isn't, then you will survive the long wait (prob 2-3 weeks) until the 10.8.4 patch comes out or worse yet the 10.8.5 major release this summer.
    Sorry this is such a long post (and for the misspellings) but sharing is caring so let's get through this together. Plus I don't know about y'all, but I spent 3K on my iMac so if this b!tch ain't gonna work like it's suppose to then it better be because of something major. . . I figured you all might be feeling the same so I should tell you just how major this bug is. And it is major, so much so that people are literally creating programs to disenfiect 10.8.3 out of their machine. If the application developer working with me comes up with a fix I will update the thread. Until then, try not to pull you hair out (~_~)
