Home wireless networking Economic Internet Access Solution

After the adsl modem routing function is enabled, my home and two neighbors share the ADSL Internet connection with the SOHO switch. Now, I want to use wireless Internet access, while the other two still use wired Internet access due to distance. How can I achieve wireless connection? Please help me develop a few feasible solutions to ensure stable and secure wireless Internet access in my house. The total investment is between 1000 and ~ About 1500 yuan.

The following wireless solutions are available for existing devices:

(1) Wireless AP + wireless network card. To purchase a Wireless AP and a wireless network card, you only need to connect the Wireless AP to the existing SOHO switch to provide a wireless network connection for your home. The advantage of this solution is that it has the least investment and can make full use of existing devices. It only achieves wireless expansion based on the existing network. The disadvantage is that you still need to use the ADSL Modem routing function. When the Internet traffic is large, the Modem performance is limited. If you select the IEEE 802.11b standard suite provided by a Chinese manufacturer, the price is roughly 400 ~ Between 600 RMB.

(2) wireless routing + wireless network card. Purchase a wireless router and a wireless network card, connect two neighboring computers directly to the lanport of the wireless route, and your home will use the wireless access method. This solution features high routing performance and efficiency, and enables high-speed Internet Connection Sharing. The disadvantage is that the investment is high and the SOHO switch is idle. If you select the IEEE 802.11b product in China, the overall price is roughly 500 ~ Between 800 RMB.

Unable to download Using BT and donkey

I use ADSL (Huawei MT800) + Broadband Router (TP-link TL-R410, IP address 192.168.1.1), three computers (IP address 192.168.3 ~ 5) All access routers share the internet. Browsing webpages, QQ voice chat, Internet Express download, and thunder download are all correct, but BitComet 0.56 and eMule cannot be downloaded, And the download and upload are both 0Kb. My system is WinXP + SP2, And the firewall of WinXP and the Personal Edition of Skynet are enabled. However, if the firewall of WinXP and Skynet are disabled, it cannot be downloaded.

Both BT and donkey need to enable a specified port in the computer. If the computer does not open the corresponding port, the two software cannot be used normally. In the TL-R410, map several ports for each machine. Suppose that the Internet 3000 to 3100 is mapped to the 3000 to 3100 of 192.168.1.3, And the 4000 to 4100 is mapped to the 4000 to 4100 of 192.168.1.4. In the machine of 192.168.1.3, set the port range from 3000 to 3100 for the BT and donkey, and use port range from 4000 to 4100 on the machine with 192.168.1.4. Others are similar.

Computers cannot be accessed in the LAN

I am a middle school teacher and I use Windows XP on the LAN. After I select "Allow access" and "allow modification" in the folder attributes, why do my colleagues double-click my computer in "Network neighbors, the "Deny access. You do not have this permission. Please contact the administrator of this machine" dialog box always appears?

Try to solve the fault in the following ways:

Check whether "Internet Connection Firewall" is enabled for the LAN connection ". If Service Pack 2 is enabled for Windows XP, the Network "properties" dialog box → "advanced" tab → "Settings" → "Windows Firewall" dialog box should be opened in sequence, and the "enable" option is selected, the "do not allow exceptions" check box is not selected. Switch to the "exceptions" tab and confirm that the "file and print share" check box is selected. If SP2 is not installed, Disable Windows Firewall.

In the network connection window, click the "Set Home or small office network" hyperlink in the left column, run the "Network Installation Wizard", and add the computer to the network again.

Specify a logon password for the current user on the Local Computer and reset the shared folder. To share folders, you cannot use a blank password to log on to your computer, or run "gpedit. msc" to directly disable "users without a password can only log on to the console.

Check whether the user name of the remote computer is the same as that of the local computer. If the user name used to log on to the computer is the same, the same password should be set. Otherwise, different user names should be used to log on.

The system is logged on by an unknown user

When my computer is connected to the campus network, it always prompts "Someone is logging on to your computer. If it is turned off, it will damage the program of the other Party ." My computer's Telnet is disabled. Why is someone logging on to my computer?

The possible cause is:

You have set up shared folders and file sharing services on your computer. Therefore, other users connect to your computer by sharing resources.

Your computer is Windows 2000 Server or Windows Server 2003. You have installed terminal services and other users log on to your computer.

The Guest user is enabled, and other users remotely access and control your computer by using system vulnerabilities.

Use the following methods:

View and cancel all shared folders. In "Administrative Tools"> "Computer Management"> "Shared Folders", you can view and disable all shared resources. Of course, you can also view the users that are connecting to your shared folder and the shared folder that is opened.

Install and enable Internet firewall. For Windows XP, you can directly enable the built-in Internet firewall. Otherwise, we recommend that you install a third-party network firewall.

Disable the guest account and Set passwords for all users.

Run Windows Update to upgrade all system security patches.

Disable the terminal service.

The speed of Internet access decreases without reason

I used a LAN to access the Internet. In the past, whether it was to open a webpage or download files, the speed was relatively fast. However, some web pages that have been frequently browsed recently cannot be opened now, or cannot be opened all the time. The web pages are displayed incorrectly. However, it is obviously not a problem for websites to let netizens test everything normally. Also, the download speed is much slower. Excuse me, why? The reason for the firewall has been preliminarily ruled out. What causes this problem? In addition, how do I set the settings for sending and receiving emails on the client (via proxy?

The reason for slow webpage opening or failure to open all web pages may be computer-infected worms. We recommend that you install Norton AntiVirus or other virus firewalls, run Windows Update, upgrade system security patches, and install and enable the network firewall. If the proxy server is infected with a worm, the Internet access speed of the entire network will be slow or fail.

The reason for slow network download speed may be that the system has installed Windows XP SP2 patch. Since SP2 is limited to 10 concurrent connections, the network download speed may be slowed down.

The setting of client mail varies depending on the proxy server. If Sygate or ISA is used, the client does not need to make any modifications. If it is WinGate, both POP3 and SMTP servers use the internal IP address of the proxy server. Set the user account to "POP3 username # POP3 server.
