• Problem with Internet access: local only for wireless in Vista

  Help, please.  I have a Dell laptop and a Dell desktop computer.  The other day, I pressed WPS on my router Netgear wireless, and since then, my desktop computer (Windows Vista Home Premium SP2) was not able to connect to the Internet.  The office is connected to my router.  My Dell (Win 7 Pro) laptop is able to connect wirelessly to the router and Internet.

  That's what I tried:
  (1) I bought a new wireless router Netgear WNDR4500
  (2) I bought a cutting mini USB wifi adapter for the desktop.  Install the driver.
  (3) reset winsock, ipv4, ipv6, dns
  -netsh int ip reset reset.log
  -netsh winsock reset catalog

  ipconfig/flushdns

  (4) order McAfee firewall
  (5) restarted several times
  (6) persons with disabilities wired and wireless enabled - I get signal green/fort
  (7) off active and wired wireless
  None of the above seem to work.  I keep getting 'Access to local only' on both cables and wireless.  When I ping yahoo.com, I get no response.
  My laptop, however, works very well in the connection to the wireless router and also to the Internet.
  Anything else I can try?  Help, please!

  Guys, I'm really hitting my head against the wall on this one, and I would be VERY happy for any help through this. Thank you!

  I thought about it, there was a corrupted installation of Norton 360, the origin of the problem. I've used the Norton removal tool and voila! Internet! Thank you.

• I only 'local only' connection, does anyone know a real solution that works?

  Hello

  My computer is a Dell XPS M1330 on Vista.
  Recently, I have noticed my wifi says identification or connected only local connection.
  Because this came I was not able to connect to any wireless network.
  I tried to connect directly via cable ethernet... still the same
  Even my 3 G Dongle says the same thing.
  The router works well because I use another computer on it, cables etc. all well tested okay with other computers.
  The computer worked fine on the router until the router is a D-Link router.
  I am pleased that the router is not the problem as all of the other computers and devices connect very well but I tried factory resetting is still no joy.
  I tried drvers off installation and reinstallation on the computer, but that networking does not work on wired, wireless or 3 g dongle I suspect something went wrong somewhere with the computer.
  Can someone please suggest a solution.
  Concerning
  Colin

• Computer connects to the network wireless as "local only".

  I am running Vista Home Premium SP2 on a HP Pavilion laptop.  I've never had any problems to connect this machine to a wireless network before, in hotels, at home, or anywhere.  My current home network is a modem - cable-> wireless-> wireless netgear n300 router.  My laptop connects to the internet via the modem cable directly or a wire from the netgear router.  I have a second, almost cell identical (it's intel, while the one who does not is AMD) which connects to the network wireless without any problem.  Two iphones connected wirelessely without any problem.  My HP laptop is the only one who refuses to connect to the internet.  Connected to the wireless network, it has access "local only".

• HP G60: update for Atheros AR5007 802. 11 b / g Driver HP G60 local only

  Hi all!

  Hoping that someone who has a lot more of an idea about this can help me because I can't really find what I need to fix this!

  Basically - I have a computer old enough HP G60 laptop running Windows Vista and using some providers of internet (SKY and Virgin Media) I can connect to the internet, but it only shows Local only. (I don't have this problem when it is connected to BT Openworld is told by the way, not sure of the relevance of this?) I can connect to my wifi with my iPhone without problems, so currently connect to the internet using the USB cable, but it's so slow!

  Is it possible to update the Atheros driver for this problem?

  Very grateful to anyone who could help me!

  Thanks in advance

  Hello:

  You probably need to install the updated wireless driver that provides support for WPA2 security.

  http://h20564.www2.HP.com/hpsc/SWD/public/detail?sp4ts.Oid=5060881&swItemId=ob_108905_1&swEnvOid=4059#

  Check to make sure that the new driver has replaced a former and indicates a date of version 2011.

  If she does not, uninstall the device by right clicking on the Atheros wireless card, select uninstall, reboot and install the new driver.

• Atheros / Vista "local only".

  Go crazy with this problem of "local only". Hundreds of discussions on this problem. Very few solutions.  My mother's laptop connects via an ethernet cable, but not through the wireless card. (Atheros).  I spent almost 6 hours dealing with this ridiculous problem.  Seriously, WiFi is a facet of base... and if the phones can do things, he should not be so difficult for a computer to do.

  Wireless connection "local only".

• 3g point hot Local only?

  I've set up the hot spot of 3g, using the droid x and 2.21. It has worked well but says local only. I have the package data unlimited, so why local only?

  Anyone knows what must be done to solve this problem.

  It adds $ 20 on the plan to use the application of the hot spot, which you? The regular data plan only covers the data directly on the phone itself, not the data that is used on another device

  problems with wireless Vista "local only".

  How is it that some machines running windows vista, when the router is updated or changed, they show "limited or local only" when you then reconnect wireless... nothing else was changed on those computers and other devices can connect ok?

  Hello

  Each router is assigned to the specific address (called IP address or IP address). And each router maintains its own database (called as base of router) to follow the networking devices communicate with him. When the router is changed, the particular router is unable to detect the device, especially the network card to communicate with the computer.  Since he does not have details of the database of network devices, communicate with him.

• I can connect to my network, but with access "local only".

  Access to the "Local" network only
  I can connect to my network, but with access "local only".  Internet became more intermittent (not sure if that is related or if I guess it) and did not work in several weeks.  Desktop computer is plugged into the router, but have the same problem when it is plugged into the DSL modem.  Other computers on the same router (wireless or other) work very well.  Recently, I removed Mcaffee and installed MS security essentials.  I uninstalled mcaffee of programs and settings then used the mcaffee removal tool to lighten the rest.  I uninstalled and reinstalled MS security essentials.  I thought it might be a firewall issue, but I get error 0x6D9 when I try to start it.  I tried all the steps in the following post, nothing helps.  Any other suggestions?

  ______________________

  You can follow the steps below and check if that helps you solve the problem.

  Method 1

  NOTE: You should do this for each network connection, even if they are disabled.

  Method 4

  Disable the DHCP Broadcast Flag:

  Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly.

  Windows Vista cannot obtain an IP address from certain routers or some non-Microsoft DHCP servers
   
  To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:

  
  1. Click Start, type regedit in the search box, and then click regedit in the list programs.
  2. If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
  3. Locate and then click the following registry subkey:
  4 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ {GUID}
  5. in this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
  6. on the Edit menu, point to new, and then click DWORD (32-bit) value.
  7. in the new area #1, type DhcpConnEnableBcastFlagToggle and press ENTER.
  8. right click on DhcpConnEnableBcastFlagToggle, then click on modify.
  9. in the value data box, type 1 and then click OK.
  10. close the registry editor.
   
  By setting this registry key to 1, Windows Vista's trying to get an IP address using the BROADCAST flag in DHCP Discover packets. If that fails, he will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.
  You can also try uninstalling and reinstalling the driver for the wireless card.
