Economical wireless Internet access solution for home wireless networking (1)

After the ADSLMODEM routing function is enabled, my home and two neighbors share the ADSLInternet 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 the ADSLModem routing function still needs to be used. When the Internet traffic is large, the Modem performance is limited. If you select the IEEE802.11b 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 domestic IEEE802.11b product, the overall price is roughly 500 ~ Between 800 RMB.

Unable to download Using BT and donkey

I use ADSL (Huawei MT800) + Broadband Router (TP-linkTL-R410, IP address 192.168.1.1), three computers (IP address 192.168.3 ~ 5) All access routers share the internet. Browsing Web pages, QQ voice chat, online express download, and thunder download are all correct, but BitComet0.56 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 ServicePack2 is enabled and installed for Windows XP, open the network "properties" dialog box> "advanced" tab> "set" button> "Windows Firewall" dialog box in sequence, the "enable" option is selected, and 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.
