Reasons for slow LAN Internet speed: poor signal, equipment interference, network configuration problems, and aging equipment.
Local Area Network
It is a computer communication network that connects various computers, external devices, and databases in a relatively small geographical area. It connects to a remote LAN, database, or processing center. This is done through a data communication network or a dedicated data circuit. Together, they create a large-scale information processing system.
LAN has a fast transmission speed, generally ranging from hundreds of Mbps to several Gbps, with low latency. A LAN helps share resources like printers, file services, and other applications. It allows for quick data and information exchange.

What are the disadvantages of slow LAN Internet speed?
The downsides of slow LAN Internet speed include effects on health, search engine crawling, website ranking, and user experience.
Impact on health:
If the Internet speed is too slow, it may cause a person's heart rate to increase and produce emotional tension. This kind of emotional fluctuation is extremely harmful to the psychology and may even cause serious illness
Affecting search engine crawling:
The slow opening speed of the website directly affects the crawling efficiency of search engine spiders.
Affecting website ranking:
The purpose of website optimization is to improve user experience and search engine friendliness.
Affecting user experience:
Users are very sensitive to the opening speed of the website. If the website opens too slowly, it may cause users to choose to leave.
Why Is Lan Internet Slow?
Poor signal:
If the wireless LAN signal is not in good condition, it may cause slow communication speed. The reasons for poor signal may include too far distance, wrong direction or obstacles.
Equipment interference:
In a wireless LAN, other wireless devices using the same frequency can cause problems. This interference may slow down communication speed.
Network configuration problem:
When using a router, if a device in the intranet occupies a lot of bandwidth, it will cause the Internet speed to slow down.
Equipment aging:
If the router or wireless LAN device is used for too long, the performance may be degraded due to hardware aging.
In summary, fixing slow LAN Internet speed needs a careful look at several factors. These include signal quality, device interference, network setup, and device updates.
