Hola. Estoy presentado este problema en mi equipo, específicamente desde que cambié el NIC que se encarga de la LAN a una Huawei SP330 con chip Intel X710-DA2.

El problema es que en los equipos Android (TV, smartphone) sin importar la marca no logran conectarse a Internet cuando uso opnsense como router con este NIC, negocian la IP por DHCP sin problemas pero no hay Internet ni acceso a otros equipos usando la interfaz web. También he notado que el NAS Synology no está negociando la IP en DHCP pero si colo IP fija tengo acceso sin problemas tanto dentro como fuera de la red. La app de Tuya y LG funcionan si estoy en la red pero por fuera de la red no se conectan a los dispositivos, en cambio tengo una cámara Xiaomi que sí se conecta desde fuera de la red.

Ya he seguido todos los pasos que me recomendaba Gemini para solucionar este problema pero ninguno funcionó, tanto el firmware de la X710 como Opnsense están actualizados, ya hasta reinstalé el sistema ya que antes de este Intel tenía una Realtek RT8127 para la lan y todo funcionaba perfectamente en todos los dispositivos, y ahora solo funcionan bien los que tienen iOS y Windows.

Espero que alguien con hardware similar pueda ayudarme

Hi everyone,

I’m troubleshooting an 802.1X issue with a Dell laptop connected through a Dell WD19/WD19S dock.

Topology:

Laptop → Dell Dock → Ethernet → Switch

When I connect the laptop directly to the switch, 802.1X works perfectly and the endpoint authenticates using dot1x.

However, when I connect the same laptop through the Dell dock:

- The switch learns the laptop's actual MAC address

- Forescout sees the laptop correctly

- But authentication is MAB instead of 802.1X

- It looks like the PC's EAPOL/802.1X frames aren't reaching the switch, causing the port to fall back to MAB

The PC's 802.1X configuration is working because it authenticates successfully when connected directly.

Has anyone experienced 802.1X/EAPOL not passing through a Dell WD19/WD19S dock?

Could this be related to MAC passthrough, dock firmware, Realtek Ethernet drivers, or EAPOL pass-through?

What was the fix in your case? Did updating the dock firmware/driver resolve it, or did you have to change a switch/dock/BIOS setting?

Any advice would be appreciated. Thanks

The other day at around 1am our WiFi abruptly turned off, we phoned the provider and they said they will send a new router but it’s going to take a couple of days at least, if anyone has any ideas on how to fix PPP connecting it would be much appreciated, I’ve tried a factory reset of the router as well.
Company is utility warehouse (trash) and the router is a Technicolor of some sort. The status light is red and the internet light flashes red. Everything else is green

My ethernet in my dorm wasn’t working so i took off the panel to see what the issue may be. Can anyone tell me if these are wired incorrectly and if so if there is any way to fix it?

We use access control for child restriction, but I noticed when accessing it that my wife's cell phone apparently feels like it should change its MAC Address like she changes her clothes. Does anybody know why?

My mother and father are looking for a good router/modem combo. What are your recommendations? Is the Arris g54 over kill? They have streaming service for their TV and play online video games on occasion, which the PC is wired. Thoughts and recommendation, thank you!

Why is the speed limited to 100Mb even though the ONU switch supports 1Gb, the router supports 1Gb, and the cable is Cat 5e?

Alright I don't know if this is the right place to post this, so I know all my cabling is good because it works when using a USB c hub with gigabit port and my mother board (gigabyte b450 pro wifi atx) is giving me an orange light indicating gigabit networking, but both windows and Linux are limiting my speeds to 100/100 it doesn't work at all if I force any of the devices in software for gigabit full duplex. It's only working with the external network card at full network speeds. I don't know if there is a setting in the bios I am missing. I just about reached the limit of what Google could give me to try.

What is NetPlus?

NetPlus is an ultimate multi-language networking toolkit designed for network analysis, port scanning, and OS fingerprinting. It combines a high-performance C++ backend engine with a Python command-line interface (CLI) and interactive console to deliver fast, lightweight network utilities.

Core Features & Usage:

Port Scanning: Scans target IPs for common default ports (FTP, SSH, HTTP, HTTPS, SMB, MySQL) or targets specific custom ports via -port.<PORT>.

Service & Banner Grabbing: Identifies open services and pulls server headers directly from open endpoints.

OS Fingerprinting: Executes TTL analysis via ping to determine if the target runs Linux/Unix-like, Windows, or custom network equipment.

Firewall Bypass: Supports the -FLL flag for advanced packet handling, fragmentation, and header spoofing.

Interactive Mode: Launch np without options to open the text-based interactive terminal console.

If someone could confirm 1e100.net being an unknown host on their end that would be great - as I allege and you can see from the pics that it’s part of a trust hijacking scheme.

Hello people, today my school announced that people with macbooks are not going to be able to access the wifi network since they got sponsored by microsoft and dont want people to use other devices.

I do not have the budget to buy a new laptop. How can i bypass this restriction on my m4 macbook.

Thanks and much love💕

What's the dumbest/longest a network issue has ever taken you to track down, where the root cause turned out to be something small? I spend half my troubleshooting life ruling out "is it even the network" before I can start, and I'm curious whether everyone's process for that is as manual as mine or if I'm missing something. What's your actual workflow when someone says "the internet's broken" and you have no idea where to start?
