18000 Hz refers to the frequency of a sound wave, not its volume. The loudness of a sound is typically measured in decibels (dB), not in hertz. Therefore, it is not accurate to say that 18000 Hz is loud. The perception of loudness depends on the amplitude of the sound wave, which is measured in decibels. **

A non-WiFi-enabled computer can be connected to the internet via a LAN cable by plugging one end of the LAN cable into the computer's Ethernet port and the other end into a LAN port on a router or modem. The computer will then be able to access the internet through the wired connection. This method provides a reliable and secure connection, especially in situations where WiFi signals may be weak or unreliable. **

One way to bypass a WiFi block is to use a virtual private network (VPN) which can help mask your IP address and encrypt your internet traffic, allowing you to access blocked websites and services. Another method is to use a proxy server, which acts as an intermediary between your device and the internet, allowing you to access blocked content. Additionally, you can try accessing the internet through a different network, such as using a mobile hotspot or connecting to a different WiFi network. However, it's important to note that bypassing a WiFi block may violate the terms of service of the network provider and could have legal implications. **

To divide 18000 by 5, you can simply use long division. Start by dividing 18 by 5, which equals 3 with a remainder of 3. Then bring down the next digit, 0, to make 30. 30 divided by 5 equals 6 with no remainder. So, the final answer is 3600. **

It is generally recommended to keep both IPv4 and IPv6 enabled on your network. While IPv6 is the newer protocol and offers many advantages over IPv4, there are still many devices and services that primarily use IPv4. By keeping both protocols enabled, you ensure compatibility with all devices and services on the internet. Additionally, having both protocols enabled provides redundancy in case one protocol experiences issues or outages. **

It is important to respect your parents' rules and guidelines regarding internet access. However, if you feel the need to access the internet for legitimate reasons, you can try discussing your concerns with your parents and explaining why you need access. You can also explore alternative options such as using public WiFi hotspots or asking a trusted adult for help in accessing the information you need. Remember that communication and honesty are key in resolving conflicts with your parents. **

To connect a WiFi-AC router to a WiFi-AX access point, you will need to ensure that both devices are compatible with each other. You can do this by checking the specifications of the router and access point to see if they support the same WiFi standards. Once you have confirmed compatibility, you can connect the two devices using an Ethernet cable. Simply plug one end of the cable into the LAN port of the router and the other end into the LAN port of the access point. This will allow the router to extend its network coverage using the access point's WiFi-AX capabilities. **

Communication between LAN and WAN devices can be enabled through a firewall by configuring specific rules and policies that allow traffic to flow between the two networks. This can be done by setting up port forwarding or opening specific ports on the firewall to allow communication. Additionally, creating virtual private network (VPN) connections can also facilitate secure communication between LAN and WAN devices through the firewall. It is important to carefully configure the firewall settings to ensure that only necessary and secure communication is allowed while maintaining the overall security of the network. **
