The valves on heating pipes are typically ball valves or gate valves. Ball valves have a spherical disc inside that controls the flow of water by rotating the handle, while gate valves have a gate or wedge that moves up and down to control the flow. Both types of valves are used to regulate the flow of hot water through the heating system and can be manually operated to adjust the temperature or shut off the flow completely. **

The quality of the connection via LAN is generally better than via WLAN. This is because LAN connections are typically more stable and have higher data transfer speeds compared to wireless connections. LAN connections also have less interference and are more secure. However, the convenience and flexibility of WLAN make it a popular choice for many users despite its potential drawbacks. **

The speed of the internet connection can vary depending on several factors, including the quality of the equipment and the network setup. In general, a wired LAN connection can provide a faster and more stable internet connection compared to a wireless WLAN connection. This is because wired connections typically have higher bandwidth and are less susceptible to interference. However, with the advancement of technology, modern WLAN connections can also provide fast and reliable internet speeds, especially with the use of newer Wi-Fi standards and equipment. Ultimately, the speed of the internet connection via WLAN or LAN will depend on the specific setup and conditions of the network. **

Downloading games via Steam is typically faster than using a CD. This is because downloading games from Steam utilizes your internet connection speed, which can be faster than the read speed of a CD drive. Additionally, Steam often has high-speed servers that can deliver the game files quickly to your computer. On the other hand, using a CD requires the physical transfer of data from the disc to your computer, which can be slower in comparison. **

Ultimately, the decision between Steam or CD comes down to individual preferences and needs. **

To connect two PCs via TeamViewer when one is connected via LAN and the other via WLAN, both PCs need to have TeamViewer installed. You will need to ensure that both PCs are connected to the same network, either LAN or WLAN. Once both PCs are connected to the network, you can use the TeamViewer ID of the PC connected via LAN to establish a connection with the PC connected via WLAN by entering the ID in the TeamViewer software on the other PC. This will allow you to remotely access and control the PC connected via WLAN from the PC connected via LAN. **

There could be several reasons why your laptop is not connecting via 802.11ac and is only connecting via 802.11n. One possibility is that your laptop's wireless network adapter may not support the 802.11ac standard. Another reason could be that the router or access point you are trying to connect to does not support 802.11ac or is not configured to broadcast on the 802.11ac band. It is also possible that there could be interference or signal strength issues that are preventing your laptop from connecting via 802.11ac. **
