I’ve been building WorldOps, a read-only digital twin for infrastructure. This demo uses my real home network, discovered from a laptop. It shows devices, Docker containers, measurements, alerts, and a timeline in a 3D view. Personal details are masked in the video.

One design choice I care about: the map distinguishes connections supported by evidence from those that are only inferred. I don’t want a clean-looking diagram to imply certainty that isn’t there.

I’d appreciate candid feedback, especially on:

• Does the 3D view help you understand the network, or add friction?

• What would you expect to click or investigate next?

• Which part feels unclear or unconvincing?

Sounds like a broadcast storm or network loop.

In the Philippines. I guess local internet providers trying to cut costs.

I have an Internet problem. I have the router broadcasts two networks 2.4 and 5G Sometimes one of them disappears, sometimes two of them, sometimes devices with this network and devices, not on the other network. And sometimes the two networks disappear completely and I have to do a UPS reset Then it is back on the job. What's the solution? I'm tired of it all

A contractor was hired to replace legacy copper wiring infrastructure for fiber which led to a huge spike in network traffic, flooding and overloading the routers. Ultimately leading a network crash. Resulting in widespread flight grounding and cancelations across the US.

Bem, eu estava jogando alguns jogos na steam e resolvi dormir, no dia seguinte abri o PC no final da tarde e derrepente minha internet estava muito lenta, mal conseguia abrir o YouTube e alguns sites, muito menos aplicativos e sites pesados, uso um TP-Link (acho que o modelo é um TP-Link Archer TX20U Nano AX1800, Wi-Fi 6, Dual Band) e uso a versão Pro do Windows 10, com isso tentei pesquisar na internet toda pra ver se tinha algum tutorial para melhor ou resolver o problema da minha internet lenta, pois era apenas e exatamente no meu PC a internet ruim, todos os aparelhos estavam ótimos, mas mesmo assim não encontrei NADA, já tentei mexer no computador inteiro, já mudei o TP-Link de USB, formatei o PC diversas vezes, coloquei outro TP-Link (mesmo modelo eu acho), já reiniciei o roteador e nada resolveu, a única coisa que mudou, foi que a internet melhorou um pouco quando formatei e as vezes (principalmente a tarde ou simplesmente do nada, mas não é por muito tempo) ela fica normal e mesmo que a internet fique um pouco melhor, a velocidade de dowload de qualquer coisa, é uma MERDA, mas de resto, a internet ainda sim está ruim e lenta, eu genuinamente não sei o que fazer... Se alguém ter alguma possível solução, será de grande ajuda!

A barra de internet fica sempre em 3 e esse é o resultado da minha internet atual (vou colocar a que normalmente fica que é ruim e as vezes quando fica boa) no site speedtest.net comparado com a que tenho no cll (eu sei que é diferente, mas mesmo assim uma comparação:

I’m a UniFi user and I’m pushing for Ubiquiti to let Dream Router 5G Max units act as mesh access points for each other, with 5G failover and the built-in screen showing mesh status. I’ve posted a feature request on the UniFi community forum. If this sounds useful to you, add your support there and share how you’d use it.

So basically my parents are saying that my PC uses all the internet so they have very slow speeds even though I've proved that I barely use that much and I'm only using 2.4ghz or smth connection BC of my WiFi card so it's slow and if I get ethernet I'll get better ping and I've explained this to them and they still say no

I need help convincing them to allow me to use ethernet or to upgrade my network card on my pc to 5ghz

Reading the updates on Friday's FAA ground stop, the cause so far is weirdly ordinary. Per the Transportation Secretary, a contractor (L3Harris) was doing routine maintenance at a remote FAA site, replacing copper with fiber. Something in that work started flooding other routers, and the routers in those facilities were made in 2001. Controllers saw radar and radio data go inconsistent, starting at the Chicago center and then Boston, Washington, New York and Minneapolis. Takeoffs stopped nationwide for about four and a half hours. They're still working out whether it was an install mistake or a faulty router.

I've spent most of my career on networking and platform code, and this is the kind of change that looks low risk on paper. It's one site and a physical layer swap. But with gear that old you often can't reproduce the setup in a lab, and one box that starts misbehaving can spray traffic everywhere if nothing upstream limits it.

Duffy's line was that by doing nothing you inject way more risk into the system. I half agree. If you freeze an old network until the full replacement lands, it keeps aging and fewer people remember how it behaves. If you keep patching it piece by piece, every small change is a production experiment on a system nobody can fully model.

If you ran a network like this, would you freeze changes until the replacement was ready, or keep doing small cutovers and spend the effort on containing the blast radius?

Hey, I’m Elwin, I work on PingMyNetwork.

We built a network simulator that runs directly in the browser. You can build custom topologies, add routers and switches, and configure everything from the CLI.

It has everything you need to practice for your CCNA or CCNP (routing, switching, etc.) without having to install or configure heavy local VMs.

It’s completely free to use, no sign-up required: https://pingmynetwork.com/sandbox

If you give it a try for your studies, let me know what you think or if anything breaks!

Was checking out Vi add-ons and came across this ₹35 one with 2 regional OTTs for 28 days.

Might actually be useful for people who mostly watch regional shows. Anyone here using it?

I need some help regarding my network connection it is working but randomly after sometime my PC is taking IP address as 169.254.198.77

I have ISP which is connected yo my Main router Asus GT BE98 it is managing everything in my home

GT BE98 ip address is 192.168.50.1

Asus GT BE98 is connected to another Asus GT6000 router in AI mesh configuration
Asus GT BE98 Lan 1 port is going to my main switch TP-Link JetStream TL-SG3210XHP-M2 v2

TP-Link JetStream TL-SG3210XHP-M2 v2 ip address router has assigned to 192.168.50.100 and i have assigned it manually in my GT BE98 router

My PC is connected to TP-Link JetStream TL-SG3210XHP-M2 v2 via Lan cable and it worked initially but after sometime its not picking up the IP address now my PC has ip address of 169.254.198.77
and i cant login in yo my Switch or Router... dont know what i am doing wrong here

EDIT: I managed to came into conclusion with the help of chat GPT also that something wrong with the communication between my PC and Asus router DHCP as i tried direct conenction also still it was same but i was able to get the IP manually assigning i tried uninstalling the LAN driver on my PC and after reinstalling it worked somehow for now.....
