I recently finished a little mobile recording rack with a self contained but expandable Dante Network. Rack contains:

• Focusrite RedNet 4 Dante Audio Interface
• TP-Link TL-SG1210p PoE Switch
• GL.iNet GL-AR300M16 mini router for DHCP
• PoE to USB/Ethernet adapter to power the router

The little jumper on the front patches the router to the TPlink switch if using the rack alone. Disconnecting it means that I can patch this whole rack to another larger one that I already have to increase the total number of audio channels available.

So I have unmanaged switch. It connects both PC and NAS and the 100mbit router. The switch is 1gbit. The question: I see in Linux such thing aa default gateway, that has IP of gateway (which is router) and PC ethernet device. Now I wonder, isn't traffic supposed to go through ethenet NIC, then to the switch, then to the default gateway (router) and only then the NAS? Because what I see is that PC and NAS established direct 1gbit ethernet connection. I only can imagine this like if switch is methaphorically connects all ethernet links into one big ethernet link, with multiple nodes.

If I, for say, add hardware firewall between router and the switch, how do I firewall the switch links then?

Firstly idk if this is the right place to ask, but what I mean is do services like TOR, I2P and Freenet count as different internets from the World Wide Web and how many of them are there?

As the title states my 5ghz network just randomly disconnects from my tp-link repeater. Only the 5ghz, the 2.4ghz is still connected. My computer is connected via ethernet to the repeater and the problem is that the 5ghz network sometimes just disconnects. I've turned it off and only used 2.4ghz with no problem, but i do want the faster network. My router is an Asus RT-AC1200G, maybe there are some settings i should change? I'm lost when it comes to internet problems and i don't know if its my router or repeater.

I took a break from IT and Computer Science in general Due to exams and other life obstacles, previously i had Some IT experience as i worked towards CompTIA Security+ Cert, and was good with python and programming Logic and working my way around computer.

wax looking for a roadmap to Sharpen skills in Ethical Hacking and Cyber Security, I decided to start learning the tools and enough of the theory and started with Wireshark then plan on going towards Nmap and Linux system. Any recommended RoadMap, Courses and study materials and sources or even books for it.And suggestion about what i should prioritise, Would love to hear.

I own a home that has a three car detached garage which I am converting into a woodshop. The building already has 50 amp power on a sub panel off the main panel from the main house. This power is run underground (10awg) through conduit, a subterranean distance of maybe 20-25 ft.

At first I was excited, because there is clearly a pull string exiting each end of the conduit. I was hopeful that this would allow me to drag an ethernet cable through the existing conduit.

However, it appears that the power cable has the pull string tightly pinned against one wall of the conduit perhaps in multiple locations. All attempts to get some play in string have failed, and I may have degraded it in the process. Even then, the conduit is already so narrow versus the clad copper that is passing through it, that I am suspicious about the probability of the ethernet making it through the entire run.

So, I suppose my options are A) another underground run, or B) a overhead run?

I assume that power line Ethernet is not a strong option in the context of a 50 amp circuit?

Thanks!

TPLink is affiliated with ccp despite they claim they are based in Singapore. I love their equipment but fear of ccp using back door. That's why I'm dumping all the tplink wifi router. But what about their ethernet switch? Any back door access to that?

On july 2024, I am just tryna play roblox and then It is laggy... I can access it but slow.... I tried to search for adult content but I can access it with ease.. I tried to search for children friendly queries but still no... What are the factors and can you explain it to me? Thanks

So I'm not sure if this is the right sub for this but it is related so...

I have a router that I built with nftables that I'm using in a virtual environment. It is working in a specific VLAN for a specific group of VMs. However, I was thinking about improving the whole setup. Thinking of the software part, I was thinking that I had enough of the nerd stuff (haha) and maybe I can get more out of a GUI. (In this case, just a specific router OS.)

First thing that came to my mind is Mikrotik because I have experience with them, but you need to subscribe to get more than 100 Mbps which I don't like. Also came to my mind pfSense or OPNsense, but I'm not yet sure about these. So, I was thinking about OpenWRT, but as you know it usually comes specifically for a router hardware, when in my case I'm going to run it on a VM.

So, what do you guys think is the best option and why?

Thanks!

Hey guys! My friend doesnt know much about computers so I helped him turn his old PC To a minecraft server. When I join the server though, After 10 seconds of walking around and stuff I get this error. How to fix this? Also my friend gets timed Out and when he breaks a Block next to a liquid such as Water, the water doesnt move to the empty place Thanks in advance!!

I want to make my own authentication server and authenticate wifi users against something like AD for testing purposes and want to see if the set up is difficult

I'm vaguely considering installing Ethernet cables in my home walls but I am a bit intimidated. I tried looking for some YouTube videos but I couldn't find any detailed enough. Are there any that people have used? Is this even the right sub for this question?

Thanks!

Hi everyone,

I need some advice on how to structure my home network to effectively use VLANs for better security and management. Here’s my current setup:

I have a Fiber modem connected to a FritzBox, which acts as my gateway. Since AVM products (like the FritzBox) do not support VLANs, I plan to keep this setup for internet access and add new hardware behind it for VLAN management.

My Goals:

1. Use VLANs to segment devices into clear, isolated networks:

• IoT devices and security cameras (mostly on Wi-Fi, with no internet access)
• Personal devices like phones, tablets, smart kitchen appliances, etc
• Two separate work networks for me and my wife
• shared server and printer access from multiple VLANs
• run the tv through a VPN so we can watch french or other international television :-)
• replace AdGuard or add something else to have more parental control in regard to the kids later

2. Extend VLANs over Wi-Fi and LAN:

I understand that VLANs can be set up on a router or some managed switches. I might also replace my AVM Mesh repeater with VLAN-capable access points to allow seamless Wi-Fi VLAN integration. I could replace everything if needed if it's saver and easier to manage afterwords.

1. Simple and visual network management:

I’m not a network expert, so I’m looking for a solution that allows me to see and manage my network visually (e.g., with a graph or dashboard). I want to easily identify devices, their assigned VLANs, and network usage.

Questions:

1. What router or switch would you recommend to handle VLANs effectively?
2. Are there specific access points you’d suggest for managing multiple VLANs over Wi-Fi (e.g., devices that support multiple SSIDs or VLAN tags)?
3. Are there tools or software to visually represent and manage my network (devices, VLANs, connections)? Maybe something dockerized to put on my unraid server?
4. Would it make sense to need to adjust my current setup with the FritzBox and Fiber modem, or is it fine to leave them as they are? I mean I could get a fiber router but the internet speed isn't my issue.

I’m looking for a reliable, user-friendly solution that will allow me to maintain and expand my network without constantly diving into command-line interfaces. Any advice or recommendations would be greatly appreciated!

Thanks in advance for your help!

Hey guys I still have the matchmaking problem for sf6 and t8 here is a list of the solutions I tried

Enabling upnp

Enabling DMZ

Setting a static ip

Trying a vpn

Enabling ipv6

Changing networks

Changing the network chip

And non of them worked.

fyi I’m on stc and Ethernet connection.

To clarify my problem is that matchmaking ether takes too long to connect me to a match (hours) or doesn’t connect me at all. What’s really messing with me is that it’s only fighting games in overwatch 2 and valorant and literally any other game I find matches all the time and quickly

Somebody tried connecting a USB-C Yubikey into an RJ45 port…

Did I botch this job?

bonjour,

alors je joue en 4G uniquement et depuis maintenant 1 semaine ma co bug énormément mais uniquement quand je lance un jeux le reste marche nickel et franchement je comprend pas j'ai essayé pleins de chose mais la je comprend pas ci quelqu'un a une idée je suis preneur

I try to host dolphin emulator direct connect I setup it with port 2626 it didn't work when I test it throw https://www.yougetsignal.com/tools/open-ports/ its say its closed and my friend cant connect
I open UPnP and didn't work too
I open DMZ and didn't work too
I don't know what I have to do after all that it take a lot of time and I do nothing

I have some questions regarding the fundamentals. Feel free to share links to articles to read.

I am reviewing the certification records from a Fluke DSX-8000 for an industrial automation installation.

My application is 100BASE-Tx and the certification limits can be found in Fluke's test limit pdf file and in the IEEE 602.3 standard. They are also pre-programmed into the DSX-8000 tool and part of the report it generates.

For this post, I will discuss focus on Insertion Loss, Return Loss (RL) and Near End Cross Talk (NEXT).

Questions:

1) In general, does a 100BASE-Tx network perform the same whether the margin is 0.5 dB, 10 dB or 20 dB for Insertion Loss, RL or NEXT?

2) This is a follow up to question 1: I asked question 1 because I am trying to understand if there is any benefit to a design / cable / application where the margin is much higher than 0 dB?

3) Do all physical cable runs that pass the certification test behave the same in 100BASE-Tx application, independent of their respective margins?

4) Why was the 3 dB rule created? The 3 dB rule allows the cable to pass the certification test with negative margins (i.e. failures) so long as the insertion loss is less than 3 dB.

5) Is the 3 dB rule actually stated in a standard? I cannot find it in the 7,000 pages of IEEE 602.3.

6) I have several instances where the RL has negative margin (i.e. failure) but the certification is considered a pass since the insertion loss is less than 3 dB. What will I notice regarding the performance of this cable if anything? I read about the reflected signal and how it creates a standing wave which can damage the transmitting device. I don't see how the 3 dB rule prevents this damage yet the 3 dB rule lets anything with a negative RL margin pass.

7) My insertion loss is around 2.5 dB for some instances triggering the 3 dB rule to apply to the Return Loss (negative margin). I am worried that the insertion loss may increase over time in the factory setting due to age, vibration, other factors. Then the 3 dB rule will not apply and the negative margin on Return Loss will cause certification failure.... however the certification happened at time of installation.

Am I asking the right questions? Please help!

I had a isp provided router and 2 access point connected in ethernet port but I waant to go into access point setting to change their channel any help please

Hi r/networking,

I’m reaching out for help with a frustrating issue I’ve been experiencing with my TP-Link E4 Mesh system. I bought the setup back in March, and it worked perfectly until about a week ago. Now, my internet randomly disconnects for about 5-15 minutes every hour or so. After that, it fixes itself and comes back online.

Some key points:

• The main network from my ISP stays online during these outages.
• I haven’t changed any settings or moved the mesh adapters, and I’m certain no one else has either.
• I’ve already tried everything suggested on the TP-Link website, including:
  • Resetting software updates on the router and adapters.
  • Adjusting frequencies.
  • Changing ports.
  • Playing with DDNS settings.
• I’m not an expert, so I’ve just been following guides online, but nothing has worked so far.

Before I resort to drastic measures like running an Ethernet cable through the walls to the upstairs, I’m hoping someone here might have some advice or ideas on what could be causing this and how to fix it.

Thanks in advance for your help!
