In this tutorial, we’re going to look at how to fix NAS network. Synology NAS users occasionally encounter such a situation: they have not used their NAS for a period of time, but find that their Synology NAS cannot connect to the Internet when they come back. As a dedicated data storage server, Synology NAS must store a large number of important files and data. Some users started to get angry at this time. But don’t worry, it’s just a small problem. In this article, I will guide you in detail how to detect the network environment and teach you...

In this tutorial, we’re going to look at how to speed up Synology NAS. Those who are familiar with NAS products must be familiar with the brand Synology, which has always been the leading brand in NAS industry. It is known for its system optimization and user-friendly experience. In fact, at the hardware level, Synology NAS also has a lot of humanized design. For example, Synology’s main performance models have dual M.2 ssd cache interfaces and multiple network ports, but not many people know about this design and how to use it. Therefore, this article will talk about how to...

In daily work, we often encounter scenarios where we need to transfer documents between computers. If there is no network device such as router in the scenario, computers cannot be connected to each other through wired LAN, and there is no storage tool such as USB flash drive, how should we achieve the transfer of document information between computers? We can set up an AD-Hoc wireless network through a wireless network card to easily achieve the fast transfer of document information. What Is Ad-Hoc Network? AD-Hoc is also known as wireless mobile self-organizing network. The principle is that one computer...

With the rapid development of Internet technology, more and more users are joining the Internet. Whether in offices, hotels, schools and homes, people need access to the Internet for office and entertainment purposes, etc. A globally unique IP address is required for communication between any two hosts in the Internet. One of the major problems with the Internet is that the demand for IP addresses has expanded dramatically and the IP address space is nearly exhausted, the use of NAT has alleviated this problem. NAT not only solves the problem of insufficient lP addresses perfectly, but also effectively prevents attacks...

In network engineering, it is easier to configure small network routes using static routing methods, but if the network is larger and there are frequent link changes, the maintenance workload of the network administrator can be very heavy or even impossible to adapt to the situation. At this point, the dynamic routing protocol configuration method will be more appropriate. Usually routes are divided into static and dynamic routes according to the way they are configured. Static routing refers to the manual configuration of routing tables by the administrator through the command to achieve communication between routers, although the static route...

We know that STP can achieve link redundancy, but when the network link state changes, STP will re-elect the root switch, root port, designated port, etc., thus generating a new tree network topology. This election process makes STP convergence time longer (usually 30-50 seconds), and such a long convergence time is not enough for some applications. How to solve this problem? The convergence time can be significantly reduced (down to 1 second) by using an improved Rapid Spanning Tree Protocol (RSTP). What is RSTP? Rapid Spanning Tree Protocol was first proposed in IEEE 802.1W-2001. This protocol allows for faster convergence...

Static NAT is to manually configure the mapping relationship between internal local address and internal global address on the router, and an internal local address corresponds to an internal global address. After setting, even if the internal local address is not converted, the internal global address is not allowed to be used by other hosts, which wastes address resources to a certain extent, while dynamic NAT technology can solve this problem very well. What is Dynamic NAT? Dynamic translation (also known as NAT pool) means that instead of establishing a fixed one-to-one correspondence between internal and global addresses, NAT mapping...

In practice, it is often necessary not only to form a network of computers in one office, but also to connect computers in several different offices separately to form a small office area network, and each office is required to be a separate network segment, and the whole office area is composed of several separate network segments. Then the switch is divided into a VLAN for each office, through the VLAN can not only limit the broadcast packets, but also prevent unnecessary access traffic between different network segments. The small office peer-to-peer network formed earlier is able to achieve the...

In this tutorial, we’re going to look at how to migrate to new Synology NAS. Some users who are upgrading their NAS are facing a problem: how to easily migrate data from the previous Synology NAS to the new Synology NAS? Here I will provide you with three options. You can choose the method according to your actual situation. 1. Hyper Backup – How To Migrate To New Synology NAS I don’t make a mistake! This backup package can also be used for migration! Its strength lies in its versatility, with almost no model restrictions. It can migrate data, packages...

In this tutorial, we’re going to look at how to setup static IP address on router. What is static IP address? There are millions of hosts on the Internet, and to distinguish these hosts, network engineers assign each host a special address, which is called an IP address. Each host can be accessed through its IP address. A static IP address is a public IP address that is assigned to a computer for a long period of time and is generally required for professional servers. Nowadays, the resources of static IP addresses are very limited, and if you want to...
