• Windows 7 wireless connection problem

  I just bought a brand new Alienware m17x and all drivers are up to date... .IM with broadcom wireless network adapter. The strange thing is that last night I was on the internet for several hours without any problem using the wireless, but this morning iwas unable to use my wireless internet access. This has happened several times now. Sometimes it says "not connected - no available connections" and sometimes he says "not connected connections are available" when she says, links, I try to connect to the network, but it says "unable to connect to the network. The only time wherever I was able to connect to wireless internet, was when my computer is automatically connected to my wireless network without me having to select the network and attempt to connect. I read things about windows 7, with a mode of "sleeper" for wireless connections or something, and that can be the cause of it and that it is better to turn off or downgrade to xp. I am really frustrated because I am not able to connect wirelessly and I hope you guys can help me find a solution.

   

  Guide to correctly troubleshoot wireless M17x
  with Dell Wireless 1510/Broadcom card
  by Glzmo

  Since many new Alienware M17x all powerful users, especially those who use Windows 7 as operating system there are various problems with their Wi - Fi connection and post threads asking how their difficulty over and over again, I decided to write this guide to show them how to solve these issues properly Commons. The solutions in this guide were created and designed for 64-bit Windows 7, but they may also work in Windows Vista, although these problems were experienced by users of Windows 7 mainly in the past. It could very well be that the problems start occurring in Vista as well with the new drivers and Windows updates.

  I. may not connect to the wireless network and or see the wireless adapter when the Ethernet cable is disconnected
  If you sometimes or always unable to connect to the wireless network, cannot connect to the wireless network when the Ethernet cable is disconnected, unable to connect to a wireless network unless you restart once to get this work and other weird problems to be unable to connect to a wireless network continue with section II. Otherwise, continue with section II..

  Sleep of a.i. Disable on disconnect device
  Some new Nvidia Ethernet drivers have a function called sleep device to disconnect. This is the culprit. Normally, it should only put the card Ethernet to sleep when the cable is disconnected, but it is buggy and thus kill the wireless connection as well.
  Follow these steps to disable this feature on your Ethernet Nvidia card:
  1. open the Device Manager of Windows by pressing Win + break, and then click on Device Manager on the left side.
  2 double-click network adapters.
  3 double click on NVIDIA nForce Networking Controller (Yes, that's indeed wired Ethernet adapter).
  4 click on the Advanced tab.
  5 select sleep on disconnect device.
  6 set the value to disabled.
  7 click OK and wireless should work again (may require a reboot later, but probably not).

  I.b. install different drivers (older) who do not have the device sleeping on disconnect feature.
  The above does not work or if you are not comfortable with these drivers, follow these steps (if step A.i. was successful, you will not need to follow these steps). Take care to create a system restore point before proceeding:
  1. click the Windows Start button in the taskbar.
  2 click on Control Panel.
  3 click on uninstall a program.
  4 in the list, double-click Nvidia drivers.
  5. Mark Remove only the following.
  6 in the box below, only check the Nvidia Network driver.
  7 click Remove and follow the uninstall instructions.
  8 restart the system, if you are prompted to.
  9 download another (older) driver from Nvidia.
  10 install the old driver.
  11 when asked what drivers you want to install, select only the network driver.
  12 follow the installation instructions and restart your system if prompted.

  II. Low or fluctuating wireless connection speeds
  If you have problems with WiFi low connection speeds (such as rates decline over time, the speeds are much lower than they should be, network lag/stutter in online games, loss of light packets, loss of internet connection as LAN works and other weird things) or speeds of fluctuating wildly without apparent reason wireless connection install the version of the Dell Wireless 5.60.18.8 drivers instead of the standard Broadcom drivers. All older drivers will usually cause the speed of connection under normal. Note, however, that you may need to install the driver manually via Device Manager as the pilot was not released for another laptop and is not officially available to the M17x yet - that's why the installer won't work. Take care to create a system restore point before proceeding.
  Here is a step by step how manually install the driver:
  1. download the drivers Dell Wireless 5.60.18.8.
  2 check out the R29128.exe file using an extraction utility like WinRAR or just run it and quit the installation program.
  3. open the Device Manager of Windows by pressing Win + break, and then click on Device Manager on the left side.
  4 double-click network adapters.
  5 double-click the Broadcom 802.11n network adapter entry.
  6 click on the driver tab.
  7 click the button Update driver .
  8 click Browse my computer for driver software.
  9 click on Let me take form a list of drivers for devices on my computer.
  10 click the disk provided .
  11 click Browse.
  12. select the folder that you extracted the drivers you just downloaded in step 1. in.
  13 select the subfolder DRIVER_US (if you are in the United States), DRIVER_JP (if you are in the Japan) or DRIVER_ROW (if you are in the rest of the world), according to the region you are in.
  14 click on the Open button.
  15 click OK.
  16 select the driver that says Dell Wireless 1510 Wireless-N WLAN Mini-Card of the list (you may have to scroll down to see - it presents itself as second to the last in the list for me).
  17 click on the Next button.
  18 you will get a warning that the driver that you are about to install is not compatible with your hardware. Ignore the warning and proceed with the driver installation.
  19 restart your system if prompted to do so.
  20 your new driver should now be properly installed and the speed of your wireless connection in the order.

  III. If all else fails (or you've just had enough of boredom arising from the Dell Wireless 1510/Broadcom card)
  Replace the Dell Wireless 1510 problem with a card half-mini Intel Ultimate N WiFi Link 5300 A/G/N (use the bluetooth as the third antenna antenna or buy you an additional antenna for this). It works very well with the M17x, has better connection speeds to strips of the 2.4 GHz and 5 GHz (this last has speeds really bad on the Broadcom/1510), it has not required to jump through the hoops to make it work properly and much more, it works with standard drivers and Intel maintains their drivers up to date. It is also much more reliable and faster as well, especially on the 5 GHz band, but also on the 2.4 GHz band.

  For more information on the subject of tweaking the settings of your Dell Wireless card, check out the official setting advanced properties: Dell Wireless WLAN Card User Guide.

  I hope that this guide will help you solve your Wi - Fi connection and allow you to enjoy speeds of complete wireless connection on your laptop Alienware M17x.

  Addendum: Quick links in this Guide

  Driver wireless Dell 5.60.18.8 version
  Download the driver for the Mini PCI Dell Wireless 1510 card used in this guide.

  Broadcom 943xx Wireless Driver version 5.60.18.41
  Download the latest Broadcom driver as an alternative to the Dell a little older driver who may or may not solve the problems more. Some have seen more success than with the 5.60.18.8 drivers with it (you need to use the 802.11n network adapter driver rather than at the entrance to Dell Wireless 1510 Wireless-N WLAN Mini Card in step II.15. the guide when you use this driver).

• Windows 8 wireless connection problem

  I just bought a new laptop with Windows 8 and half an hour to put on, I lose network connectivity wireless on all devices in my home, new laptop, iphone, ipad, galaxy tablet.  The ipad, the iphone, and the Tablet first in loose connectivity followed by the laptop.  As soon as I turn off the phone followed by the router (BT homehub 1 I think), connectivity is restored on the ipad, iphone and tablet.  When I turn on the laptop back, connection is restored there too but not for long.  I checked the router and all the lights are lit and not flickering.  I ran the Windows diagnosis and this is the result «a network cable is not plugged in correctly or may be broken...» Detected (there is a yellow triangle with an exclamation point in it which I assume means not fixed...) Problem with access point or wireless adapter... Fixed).  I checked all the cables and they look very good.  BT send me a home 3 hub even if they don't think that the router is the problem.  I remember not being near the router when I first created the connection with the router wireless.  Not sure if it is relevan.t I am at my wits end.  I am not knowledgeable about these things, and after having my laptop for a week I could not enjoy it at all.  Thank you

• Window7 & RaLink 802.11n & problem of the Netgear WPN824v2 router wireless connection

  Kevin Hau recommends a new thread to solve individual problems.  It's here.  In February 2010, I bought a new LG X 130 notebook with Windows 7 starter pre-installed.  On the first day, connection Wi - Fi was intermittent, although wired connection works well.  Links for laptop to a Netgear WPN824 V2 router.  This router has a wired to my PC and wireless for Toshiba laptop of my wife.  These work perfectly.  The latter two works on Win 7 Home Premium.

  I put WEP as a security measure for the router and wireless connections.  The LG X 130 connect wirelessly from a cold start about 25% of the time.  When it is not connected, no problems.  It should be necessary to restart, otherwise the computer expires then all that I get is "no connection is available" and there is absolutely no way to reconnect.  Cold boot does not work and the computer seems to need to set off for several days before it will condescend to connect again.

  Internet gives hundreds of 'my solutions' research which none appear not to work.  All the drivers are up to date and the latest versions.  I tried without security, WPA, WPA2, as some people suggest that 802.11n does not support WEP.  I tried b & g 108Mbps mode rather than by car.  All of these more recent attempts have failed to get any connection. On a recent trip away, the laptop could find the hotel network, but not connect to it.  He made a useful paper weight!

  The problem is clearly intermittent.  The laptop was returned twice to LG.  For the first time, they reinstalled everything, got a connection and returned.  The second time, they got a call and returned.  I can get connections, but I can't keep or make it reliable.

  Grateful for a solution.

  everything indicates material ralink or driver at this point... here, I had a
  best answer.

• How can I make best use of Windows XP wireless connect?

  This may seem Basic, but I want to understand all aspects of the configuration of my PC of course. As long as I connected to the wireless Web, I used a software provided by Netgear, that makes the wireless adapter. When I moved into an apartment, the ISP technology who set up my wireless modem could not get Netgear to "discuss" the modem, so he opted for the default Windows software. I'm not real surprised because Netgear has always been a little bug. However, I know the zip on the Windows login. Is it as simple as right-clicking on the icon in the status bar system and by taking my selection of disable, status, repair, view available wireless networks, change the settings of Windows Firewall or open network connections? Are there additional features? Y at - it online a tutorial on the use of Windows for my wireless Internet connection?

• Windows 7 wireless connection problem: unable to connect to my home network

  Hello

  I just got a Dell laptop that is running Windows 7.  However, when I try to connect to my home network it impossible apperantly.  When I select "Troubleshoot Proplems" I get "Troubleshooting cannot identify the problem."

  I also already checked the pit of the Wireless Device Manager device.  It is activated and works perfectly.

  I know that the network is enabled and works because I'm typing this message on my desktop wireless capable of Windows XP.  In addition, my roommate is able to connect to the router and 'surf' the internet on their laptops.

  Therefore, I must assume that this problem is due to something in Windows 7.

  Hello Geoffrey.

  Have you tried to change the wireless channel that your router is running at? There may be interference that could prevent the internet connection:

  Take a look at step 6 in this article that give more details about it:

• Internet problems with a computer Windows 7 wireless

  Hello. My problem is that I have an ACER with Windows 7 computer and I've had it for awhile (about a year or more). He never gave me no internet problem until a few days ago, when he started having connection problems. My computer has been without internet since two and a half days. Whenever I try to look for the problem, he tells me that the computer is connected to the router, but that router is not connected to the internet. I tried to restart the modem and the router several times without success. The thing is that, while my computer does not have internet, my cell phone and the computer of my partner (for laptop with Windows 7) do not seem have a problem using the same network of the internet, which makes me believe that the problem is in my computer.

  I have a SB5101U of Motorola SURFBoard Cable Modem and a NETGEAR RangeMax 150 wireless router.

  My computer uses an Atheros AR5B95 wireless network card. (My partner runs Realtek RTL8188CE wireless adapter)

  Would it be a virus or something? Because I've scanned my computer with my antivirus to find something wrong, but it does not yet detect. Please help me and thanks a lot for any help or advice you can give me.

  You have McAfee?  If so, see this "criticism" McAfee reviews -

  Some customers may experience a loss of network connectivity and/or errors in McAfee Security Center after a recent update

  You should make the fix McAfee, if necessary. There are corresponding communications for their enterprise products.

  I had to run their removal of McAfee Development tool a few times before and it caused a problem with the license if the PC was not connected to the internet during the abduction. Due cat of McAfee support reset their files in order to allow the relocation-reactivation. Here is their link cat - McAfee - media contains the link to the cat

  I got McAfee, but the connection has started working again on its own so I thought I was clear of problems. However, when I checked it says he was doing routine checks the updates in vain when I told it to do a manually. So stick with McAfee you don't follow their procedure of fix would have upgraded my PC at risk by not updated and, like other McAfee ads have since explained, the application did not refer to its database of threats correctly [and this could explain part of the variability of the symptoms of failure but all involved loss of internet connection]. Actually, I removed McAfee then installed Microsoft Security Essentials rather & my answer IE is faster I knew it [even though I had the Add-ons McAfee disabled for centuries].

• Pavilion dv7-7205tx envy windows 8 wireless connectivity

  A first tried the sticky post and when trying to update the drivers available via this link, windows 8 still sees the current drivers as the most up-to-date.

  There is no info on this laptop on HP site so I can't update all the drivers myself right now, so if someone can tell me the right drivers who can fix a problem with the Atheros QCA9565 wireless I would appreciate it.

  Using Windows 8, fine internet connection via ethernet to Dlink Di526 (oldschool Yes..)

  2 other pc Windows 7 have thin connection to the wireless router

  Phone selects picks up wireless and connects very well

  Try wireless on HP and it detects the network but can connect only with limited connectivity, no internet.

  Driver for Atheros is 10.0.0.77 dated dated 15/08/2012, and I tried the 10.0.0.212 in date driver dated 28/09/2012 with the same result.

  I think that its a problem with the Atheros with Windows 8 compatibility.

  Anyone else has a similar problem?

  Have you tried the driver found here to your support portal for portable computers on the web page of drivers and applications?

  The driver is for Windows 8 (32 & 64-bit)

• Problem of DNS in Windows server 2012

  Hi guys,.

  I'm a newbie here and I hope to get help with my question.

  I have a server DNS (192.168.1.55/24). Everything is already configured, the IP address and host names are already mapped and is already working. Now the problem is... I example. Metro.com, when I'm in the same segment (192.168.1.x 24) I am able to access example.metro.com using only his "example" hostame in run. (windows + R, then \\example). When I ping, he also responds with the correct address w/c IP is 192.168.1.11 being. Now, I have another VLAN in my network is 10.1.1.0/24 and 10.1.2.0/24, these VLANS are able to see the 192.168.1.0/24 because I have a cisco layer 3 switch. When I use the DNS 192.168.1.55 segment both 10.1.1.x and 10.1.2.x, so I am able to still ping example.metro.com and able to access. But what happens is, I'm not able to access using only the host name-example term. Is there something I need to configure on the DNS server to have it working? I might have exhausted all procedures, but still can't make it work, and I'd really appreciate that someone can give me a help and advice.

  Once again...

  1. I'm on the 10.1.1.0/24 network

  2. I use 192.168.1.55 as DNS (which I am able to ping, btw)

  3. it can translate example.metro.com to 192.168.1.11 when I ping.

  4. IM NOT in MEASUREMENT of ACCESS IT USING ONLY \\EXAMPLE term I can when I'm in the same segment as the server DNS 192.168.1.0/24.

  Thank you!!

• Problems of DNS on Windows 7 ping a host within a child domain

  Hi, I have a few interesting problems with windows 7 DNS.

  Here are the details:

  Windows 7 Enterprise 32 bit computer, joined a Win2k3 AD.
  my domain name for example of purposes is called corp.example.info.
  I have a child domain: prod.corp.example.info and in this child domain
  is a host: 'test '.   COMPLETE the test domain name is: test.prod.corp.example.info.
  In this case, 'test' is a CNAME, but the error occurs regardless
  the type of DNS record.

  My problem is that if I ping test.prod I get host not found.
  If I ping test.prod.corp.example.info, everything works fine.

  If I do a nslookup on test.prod, I get the correct results.
  If I do a nslookup on test.prod.corp.example.info I get the correct results.
  (This tells me that the files work correctly in DNS)

  I have no firewall on my Win7 machine, or something funky.

  I have other operating systems in the field: machines RHEL4 and RHEL5, WinXP, HP - UX
  and each of them can properly resolve "test.prod" correctly. I have not tried on Windows Alaric, as there is no shortage of it here.

  There is no entry in my C:\windows\system32\drivers\etc\hosts file and it is not damaged.

  I tried ipconfig/flushdns / release / renew, /register/ etc. nothing works.

  I have an IP address in the DHCP scope for this particular machine,
  but the machine receives its IP address from the DHCP server (not sure that it of important, but including at least)

  All advanced settings on my Win 7 IPV4 stack corresponding parameters of the functional XP machine.

  I made trace wireshark on my machine Win7 and XP machines, and here are my results:

  WinXP:

  (1) client machine sends a query to the DNS server (in this case, my domain controller)
  'test.prod '.
  (2) DNS server returns a "No Such Name" standard query response

  (3) client machine sends a DNS query for "test.prod.corp.example.info."

  (4) DNS server returns a response of standard query with the correct record.

  Win7:

  (1) client machine sends a query to the DNS server (in this case, my domain controller)
  'test.prod '.
  (2) DNS server returns a response of "No Such Name" use query

  At this point, the Win7 machine gives up and returns could not find host.
  Naturally, I checked my settings advanced IPv4 and verified that they are identical to the work
  XP machine.

  Microsoft gurus out there have a preview?

  Thank you!
