Win7 wireless networks are restricted and unblocked

A lot of netizens are asking me, Win7 network connection is limited. Here to give you a detailed explanation, because of the added QQ is still very troublesome.

Win7 The network is not able to connect properly. Let's now analyze the reason:

(In fact, computer problems are two reasons software + hardware, general hardware is no problem, so we do not do in-depth discussion)

Now most of the internet is the use of routers, in the same local area network may have a machine this situation, from the router to direct connection to the broadband can not solve the problem, but this row in addition to the problem of network cable.

Your IP set for automatic access, in fact, from the DHCP server to obtain IP and related parameters (the white is from your router to obtain IP address, but now most of the routers are Shanzhai version, performance must be flawed, so we have to see if there are problems with DHCP)

First go to the Network Neighborhood--View the Internet connection--right--state ... Look at sending and receiving one of them is not 0. If that's the case, you might want to see if the cable. Something's wrong.

The local connection on the computer shows that the restricted or connectionless connection is related to the network server and NIC. It's a network problem anyway, with the computer

It's not much of a relationship.

Your network card TCP/IP protocol, set up an automatic access to IP address, [url=http://www.zhaoyuwen001.net/] wireless network password cracking [/url] However, your LAN does not exist to allow your machine to get IP address

DHCP server. So your IP address is not secured, of course, restricted or connectionless.

Solution:

Personal Summary: XP can, why win7 you can? In fact, this is related to the system, it is well known that Win7 is a new system, so the problem appears in the hardware (NIC and router) and software (Win7 system). Frankly speaking is incompatible cause, so the general solution is to update the network card driver, set IP, DNS, routers. (Just a personal point of view, if there is something wrong, please testify! Mo jjww)

1. The problem with the firewall. Shut down the firewall there is no such hint! However, it is not recommended to turn off the firewall (XP recommendations are closed, Win7 's recommendations are not closed)! No effect on your use

2. Network right key properties → Select Change adapter settings on the left side → Local connection right key properties → installation → selection protocol → add → select reliablemulticastprotocol (Reliable multicast Protocol) protocol → OK, ok!

The local connection properties inside the TCP/IP Protocol Properties dialog box open, and then the player to configure IP (manual IP you see the next computer IP can), point OK. This includes the settings for DNS.

3. Router problem, you need to enter the router to set your IP address segment and the DHCP server to open. No line by encryption, you set up a shared secret key? Set to open system try not to, look at the route inside the MTU is not 1500, manually set to <=1452, generally set 1452 can be resolved.

The router firmware version is too low to be compatible with Win7, go to 192.168.0.1 upgrade the router firmware version, reset the router after resetting, the results of the Internet all normal.

4. Run command Cmd--netshintipresetipconfig/flushdns (this is the clear computer DNS cache command)

5. Invincible appearance, the problem of the network card, generally will not appear, if there is, update the network card driver, not yet you go to repair

The other two approaches are first: the preparatory work:

1, Drive home Download Driver wizard Download the latest authentication version of the wireless card driver.

2, uninstall the wireless network card, that is, in addition to the cable network, the rest are all uninstall and remove the driver (must be fully uninstalled, if the resolution is not clear, the cable driver is also downloaded, and then all network devices Uninstall and remove the driver).

3, after the successful uninstall, the hardware changes, there are 2 unrecognized hardware (win7 automatic installation failure prompt).

Restart the computer.

4, after reboot, install just under the good wireless card driver.

5, install and restart the wireless router at the same time.

6, the installation of a good theory will be no problem. There is still a problem with Win7 's automatic driver compatibility. So replace it with the most appropriate driver for your hardware.

Second: The use of Win7 shoes may have been linked to the wireless network after the hint network access Limited, not normal Internet access. In fact, this is the Win7 system setup problem. How to solve it?

This is the "common fault" of the WINDOWS7 system, which can be solved by Group Policy setting.

1, first open the Group Policy window, in turn expand "Computer configuration → management template → system →internet Communication Management →internet communication settings";

2, and then in the right window, locate the "Turn off activity test for the Windows Network connection status indicator," and then modify the property to "Enabled" after double-clicking.

Set up the network after the normal access
