Problems with the WAN port of the router, or network cable (connector)

 It happens that the WAN port on the router fails, to which we connect the Internet. For example, after a thunderstorm . Or there is a damage to the network cable that goes into our house or apartment. Usually the contact in the connector itself disappears. And the router simply stops seeing the cable connected to the WAN port. I wrote about this in detail here: the router does not see the Internet cable. The WAN port is not working .

I have even met a situation more than once when the router does not react at all to the connection of a network cable to the WAN port (the indicator does not light up) , and at the same time, when the same cable is connected to the computer, the Internet works without problems. And if the reason is not in the port of the router itself (it works with a different cable) , then the problem can most likely be solved by re- crimping the provider's network cable . Or by replacing the cable (twisted pair) .

Computer networks are the basis of communication in IT. They are used in a huge variety of ways and can include many different types of network.

If the WAN port is out of order, then there is usually a repair, or the purchase of a new router. There are models where you can use a LAN instead of a WAN port. Or flash your router with some third-party firmware (DD-WRT, OpenWrt) , which has the ability to reassign the port. But this is already like that.

What is a DDoS Attack? A Simple Definition

Since we’re all about making technical topics simple, let’s start with a basic answer to the question: What does DDoS mean (a.k.a. “What is a distributed denial of service attack”)? As mentioned above, a DDoS attack is a bit like a traffic jam on a website (but it’s intentionally caused by a hacker). Here’s a simple definition for the meaning of DDoS: A DDoS (distributed-denial-of-service) attack is when a hacker makes a website or other service inaccessible by flooding it with requests from many different devices. If you’ve also heard the term “DoS attack,” don’t let that confuse you. A DDoS attack is just a specific type of DoS (denial-of-service) attack — one that uses multiple computers/devices to attack with. How Does a DDoS Attack Work ? Just like a traffic jam floods a highway with more cars than it can handle, a DDoS attack floods a website with more requests (i.e. visitors) than the web server or other related systems can handle. Many hackers use botnets (a.k.a.

How to prevent a DDoS?

Keeping yourself protected from DDoS attacks is something that is often easier said than done because of the fact cybercriminals will often stop at nothing to gain unauthorised access to private data, and many international brands such as Netflix, AirBnB, and Spotify have all become victims in the past. In spite of this, there are certain things that can be done in an effort to prevent a DDoS attack from occurring. Denial of service attack definition Firstly, you will need to make sure that any firewalls and routers are configured in the correct manner and applied with up-to-date security patches. Similarly, it’s also worth regularly checking for security updates for your Internet of Things (IoT) devices and adding a password where possible. This is because these devices have been increasingly targeted by hackers in recent years. Doing everything in your power to keep things up to date will ensure that any bogus traffic is promptly rejected during a process whereby network traff
