You don't have to be a computer network administrator to get into a situation where you have to attach a connector (RJ 45 or RJ 46) on the spot;
Simply, you bought a TV that also has LAN available, in order to be connected to the Internet wired, you need a network cable to your router. If the connection goes through the ceiling and you have to drill holes, it is difficult to run the cable with the connectors already installed.
The procedure itself is called "Crimping" and it is nothing complicated, the only thing that requires a suitable tool, and a suitable arrangement of wires considering the purpose of the cable.
So let's go;
You need a network cable of suitable length (every IT shop has it) and a pair of LAN connectors, and you can borrow a crimping tool:
First of all, the insulation should be removed from the mains cable, either with a tool or with a scalpel. What length of bare wires (pairs) should be left, you will understand on the spot when you try to push them into the connector, because fixing with pliers goes first over the insulation (physical contact) while at the same time establishing contact with the contacts (electrical contact), by breaking through their thin plastic sheath with sharp tin contacts (which are integrated into the connector).
How you will arrange your personal wires depends first of all on what type of cable you want to make:
T568A or T568B
After that, the wires should be arranged according to the TIA/EIA 568 standard A or B. In case of making a crossover cable, one connector is made according to the A standard and the other according to B. For non-crossover cables, both connectors have the same arrangement and it does not matter whether A or B is used. For normal connection, a non-crossover cable is used.
The combination of these two standards (on one side one type of connection (T568A) and on the other another (T568B) is needed, for example, when you network two computers directly with a network cable...
That is, you connect their network cards directly, with a crossed network cable. (one standard to another)
When you have chosen the combinavia, insert your personal one into the connector, then into the pliers and, like any other good thing, just squeeze :)...
So step 1.
step 2.
Result: your cable is ready, connect it! In case it doesn't work, there are also testers to test the LAN cable....
How to Set Up Parental Controls on Your Network — Step-by-Step Guide
How to Set Up Parental Controls on Your Network — Complete Step-by-Step Guide
Protect your children online and manage screen time with router parental controls, DNS filters, and third-party apps. This guide walks you through setup, best practices, and troubleshooting for all major routers.
🔒 Why Use Parental Controls?
Parental controls let you block inappropriate content, limit online time, and manage which devices can access the internet. Implemented correctly, they provide a safer online environment and reduce arguments about screen time.
Parental controls give parents tools to manage kids' online time and content.
📋 Overview — Methods to Control Access
Router-level parental controls — built into many modern routers (best for device-wide control).
DNS filtering — uses services like OpenDNS to block categories (easy and robust).
Router apps / vendor ecosystems — TP-Link HomeCare, Asus AiProtection, Netgear Circle, etc.
Device-level controls — built into iOS, Android, Windows, or via apps (applies per device).
⚙️ Step 1 — Log Into Your Router
Open a browser and type your router’s IP (192.168.1.1 or 192.168.0.1). Log in with the admin username and password. If you don’t know them, check the router label or the manual. For safety, change default admin credentials if you haven't already.
Router admin page — access it to configure parental controls.
🧩 Step 2 — Locate Parental Control Settings
Router menus differ by brand. Typical places to look:
TP-Link: Parental Controls / HomeCare
Asus: AiProtection → Parental Controls
Netgear (Nighthawk): Circle with Disney → Parental Controls
Linksys: Parental Controls or Access Restrictions
If your router UI is limited, check the vendor’s mobile app — many router apps have friendlier parental control pages.
🧾 Step 3 — Create Device Profiles
Identify the devices your children use (tablet, phone, gaming console). Create a profile for each device or user to apply rules individually.
Find Device List or Attached Devices in the router admin interface.
Note device names or MAC addresses.
Create a new profile (e.g., “John-Tablet”, “Anna-Phone”) and assign the device to it.
Assign devices to profiles so you can apply different rules per child.
⏱️ Step 4 — Set Time Limits and Schedules
Most routers allow scheduling internet access (e.g., weekdays 07:00–19:00; bedtime block 21:00–07:00). Use this to:
Limit daily screen time
Block internet during homework time
Disable access at night to improve sleep
Example rule: “School days: allow 2 hours of internet (17:00–19:00); Weekends: allow 3 hours (10:00–13:00 and 16:00–19:00)”
🚫 Step 5 — Block Websites and Categories
You can block websites one by one or block entire categories (Adult, Gambling, Social Media, Streaming, etc.).
Domain blacklist: add specific domains like examplebadsite.com
Category blocking: use router-provided categories or use DNS filtering (recommended)
Block access to specific sites or categories from the router’s control panel.
🌐 Step 6 — Use DNS Filtering (OpenDNS FamilyShield / CleanBrowsing)
DNS filtering is a powerful and vendor-agnostic method. It blocks domains at DNS lookup time — requests to blocked categories never resolve.
iOS (Screen Time): set app limits, downtime, and content restrictions.
Android (Family Link): manage apps, limit screen time, and set device bedtimes.
Windows (Family Safety): manage websites, app usage, and screen time per account.
Combine router-level and device-level controls for the best results.
🔎 Step 9 — Monitor and Test
After setup:
Open a blocked website on a child’s device to verify it’s blocked.
Try scheduled times to confirm access windows work correctly.
Use router logs (if available) to see blocked attempts and which sites were requested.
🛠️ Troubleshooting Common Problems
Rules not applied: ensure devices use the router for DNS (not a manual DNS on the device) and clear device DNS cache.
Child uses mobile data (4G/5G): parental controls don’t apply to cellular — use device-level restrictions or restrict installing mobile data apps.
Smart TV or consoles bypass filters: set static IP + apply filtering on that IP, or mark the device profile in router UI.
Performance issues: some routers slow down when heavy filtering is enabled — consider a modern router or dedicated DNS appliance.
✅ Best Practices & Tips
Combine router-level controls, DNS filtering, and device-level limits for a layered approach.
Explain rules to your children — transparency encourages better behavior.
Regularly review access logs and adjust categories as kids age.
Use strong admin credentials and disable remote management on the router.
❓ FAQ
Q: Can smart devices (IoT) be controlled by parental rules? A: Yes — add IoT devices to the router, create a device profile and optionally block internet access hours. For fine control, isolate IoT on a guest network.
Q: Is DNS filtering enough? A: DNS filtering is effective for category blocking, but tech-savvy users can bypass it (VPNs, alternate DNS). Combine with device-level controls and app restrictions.
🔚 Conclusion
Setting up parental controls on your network protects your family and gives you tools to manage screen time and online content. Start with router-level rules and DNS filtering, add vendor apps for convenience, and complement with device-level controls. Review policies regularly and adapt as children grow.
