• Specific update for Windows on Windows 7 disables the internet connection in Internet Explorer

  I have Windows 7 Home Premium 64-bit. 10/14/2010 my computer installed something around 18 updates to Windows. Immediately after the restart, I couldn't get an internet connection on Internet Explorer. My computer tells me I have 90% Wi - Fi, but I get nothing on Internet Explorer. I restored my computer to until I installed updates, and immediately after the restart of the internet worked well. I decided then to individually install each update of Windows one by one and found a specific update that causes this problem on my computer. It's "Cumulative Security Update for Internet Explorer 8 for Windows 7 x 64-based Systems (KB2360131). I am able to install all the updates, only this specific one stop my internet to view Web pages.

  [I turned first on my new computer on 30 August.] I tried to activate [the 60 days Norton free trial] in the first week or two, so maybe between 7 September - 14 September... not [uninstall before I installed MSE] however.

  You must have activated the free trial immediately (i.e., August 30), not a week or two later. In addition, you should have uninstalled Norton free trial AND download / run the Norton Removal Tool BEFORE you installed Microsoft Security Essentials.

  I suspect that you see the effects of a hijackware infection. Chances are that your computer is already infected at the time wherever you tried to activate the free trial of Norton. See...

  Personal data backup (which none should be considered 100% reliable at this point) then format the HARD disk and do a clean install of Windows. Please note that a repair installation (upgrade AKA on-site) will NOT fix it!

  NOTE: If your computer came with a set of disks, there is a hidden partition restore (not to be confused with the restoration of the system) you would use to do the clean install (AKA a "destructive recovery").

  After the new installation, you will have the equivalent of a "new computer" once again in order to take care of EVERYTHING on the next page before connecting the machine to the internet or one local network (i.e. other computers) AND BEFORE to plug in a flash, SD card, or any other external drive to the computer otherwise:

• Problem with internet connection Wi - Fi Windows XP - very 'slow' packages

  Hi people, this problem has been driving me crazy for weeks, so I wonder if someone can provide a solution! Sorry for the long post, but I tried to put in as much information as possible.

  In short, I decided to rebuild an old laptop in Windows XP (2006) I (latest updates installed). I'm without audio (cannot find drivers), but this isn't so much a problem. The problem needs to connect to the WiFi.

  The internal WiFi card is an Intel (r) PRO/Wireless 2200BG (or, at least, it's the driver).

  WiFi is displayed as 'Connected' and ' Signal strength: Excellent "(as my laptop is sitting right next to the hub). Ethernet (wired) connection to the hub works perfectly. I have WiFi BT working connects perfectly with my Mac and my iPod, I know that there is absolutely no problem with the router.

  However, my laptop does not seem to want to connect WiFi, despite 'positive' messages above. All browsers (IE, Chrome, Firefox) display a message stating that they cannot connect to the internet. Nothing in browsers suggest that all DNS settings have been changed.

  I * think * the problem might be because the packets sent/received are still very low - if either enter three digits, I have a lot of luck. For now, they are stuck on envoys = 14, received = 3.

  So, what I have checked/tried is the following (all based on Google search) - none have worked:

  (1) I can confirm that the automatic Wireless Configuration is enabled, started and set to automatic, and that Windows is used to set up my network.
  (2) my wireless network appears in my favorite networks and is automatically connected to (or should be :-)) - I have added/removed the connection several times, check the wireless key, every time, without success.)
  (3) the TCP/IP menu is configured to obtain an IP address and a DNS service automatically.
  (4) type ipconfig/all at the command prompt seems to show that everything works OK:

  • The physical address is: 00-16-xx-xx-xx-xx (I removed the last few digits as it is an open forum, but is probably not a security issue)
  • DHCP is enabled.
  • Automatic configuration is enabled.
  • The IP address is 192.xxx.x.xx (as above)
  • Subnet mask is 255.255.255.0
  • Default gateway, DHCP and DNS server are all the 192.xxx.x.xxx (as above)

  However, IP routing is NOT enabled or is Proxy WINS. Node type appears as unknown.

  I tried the DNS, IP address in the command line (don't remember the command), hot flashes reset everything I can think of or have found via an internet search.

  I also tried the two separate Wireless USB key (only install the drivers - now deleted), which is not working.

  I am so right in thinking that everything seems OK, except the transfer of packages very low? Anyone who has any other control I can try - or better yet, a potential solution?

  Thank you!

  Hello c0ley,

  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:
  http://www.Microsoft.com/athome/Setup/wirelesstips.aspx
  If you need assistance to change the settings of the specific router, you will need to contact your router manufacturer or your internet service provider.

• Internet connection only in Mode safe mode with networking

  I was using the Internet at home, when I had a pop up telling me there was an anti-virus program download. I pulled out the window pop-up, rebooted the computer and turned on safe mode with network. I thought it was just a problem of virus/malware/spyware. Since I installed several programs to prevent/remove any type of spyware (virus, etc.), I decided to run in safe mode, just in case. I ran the and after he said that my computer was clean, I restarted the computer in normal mode. The internet, however, did more work. He said that the Internet connection was closed portals HTTP, HTTPS and FTP. He also recommended that I check my firewall settings. I use the internet in safe mode with networking, and it works here though.

  I'm not really sure what the problem is with the internet settings. I could really use some help!

  Hi AngelicaR,

  OK, you should now check your firewall settings, to do so right click my network connection on your desktop-> select Properties (or click Start-> Settings Control Panel-> network connection)

  Now right click on your connection to the LAN->-> Advanced->-online advanced, settings, settings-the default settings online-> restore default settings. This will restore the default firewall on your local network connection. Click ok on the screen and restart your pc to see if its working.

  If you find the same problem again and then come to the same path: required connection to the local network-> settings-> Advanced-> settings-online Exceprions-> Tickmark the HTTP, HTTPS and FTP, also tickmark "display notification when firewall blocks a program" that will help you the notification to allow access through the firewall. Click ok on the whole screen, restart your pc.

  I hope this helps.

  Hello

  Keep the changes and open the wireless. For example, to disable security in the router (turn on when to managed to connect).

  You can also try the wireless in a friends house, or an Internet café to get a frame of reference for this behavior elsewhere.

  -------------------

  Wi - Fi in general.

  These steps and tell us where is the breaking point.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  ------------------

  The wireless card drivers much also install utility wireless of the seller.

  Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

  ----------------

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled).

  If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

  If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

  party like Hello and NetMagic 3rd network managers can block local traffic too.

  ---------------------------

  Stack TCP/IP work should look like.

  Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

  http://www.ezlan.NET/Win7/status-NIC.jpg

  Description is the data of the card making.

  The physical address is MAC of the card number.

  The xx must be a number between 0 and 255 (all xx even number).

  YY should be between 0 and 255

  ZZ should be between 0 and 255 (zz all the same number.)

  The date of the lease must be valid at the present time.

  * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

  * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

  ---------------------------------------------------

  A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

  Above everything is OK, you must be able to connect to the router.

  Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

  If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

  Enable security wireless after you eat to make a functional connection.
