#wi-fi — Public Fediverse posts

Something happened, I don't understand it.

I have a Teltonika RUT240 as a #wifi AP which serves a Raspberry Pi 3, a 4, a Raspberry Pi Zero 2 W, and a RPi Pico. All devices are within very close distance (2 - 3m).

Last night, something happened. Three of the four RPis show very high packet loss despite very good RSSI values and Link Quality. The fourth remains rock solid. There are no other Wifi networks within 50m of the AP.

I switched channels, and a dozen other WiFi parameters. Reduced the WiFi TX power on all devices I could, switched off power saving modes. Rebooted the AP. Rebooted the devices. Nothing changes. That one Pi is rock solid, immediately reconnects to the AP and has RTTs < 5ms, while the others are extremely unreliable, no matter what I do.

I am 800km away from the location, so I cannot do anything physically to it right now.

Open for suggestions what may have happened here, or how to debug this mess!

Как определить местоположение людей по Wi-Fi с помощью BIM и статистики использования помещений

Насколько точно можно определять местоположение людей с помощью Wi-Fi? А что если дополнить это BIM-данными и инфой об использовании помещений? Рассказываю о том, что мы с коллегами напроверяли, как решали задачу и какие результаты получили в очередном проекте.

Comcast gives its Wi-Fi motion detector a security makeover

Has anyone asked for this feature? I cant see how this is a good idea from a consumer or privacy standpoint.

I am sure it will not be abused in anyway. /sarcasm

Yay, your ISP is monitoring whether or not you're home based on Wi-Fi signals. That info won't leak, no siree! We can't abuse that in ANY way....

"...WiFi Motion can monitor activity in your home and send you notifications, similar to a standalone motion sensor. It works by detecting disruptions in the Wi-Fi signal between the Xfinity gateway and any Wi-Fi-connected device, giving you some insight into what’s happening in your home without buying additional hardware...."

Умный дом начинается с роутера или где искать слабые места домашней IoT-сети

Если умный дом уже настроен или вы только собираетесь это сделать, есть ещё один вопрос, о котором легко забыть, о безопасности домашней сети. В этой статье разбираемся, зачем отделять IoT-устройства, какие настройки проверить на роутере и что можно сделать без сложной сетевой инфраструктуры.

I'm currently exploring the weirder corners of the DS library. The heck is this? Pokemon Go before it was cool?

Best as I can tell, it's a game where you walk around collecting 2.4 GHz wifi signals. Gotta cache them all! https://en.wikipedia.org/wiki/Treasure_World

#eduroam is a very popular #WiFi authentification system for students worldwide. A user asked for help at the #Gentoo Booth at the @froscon today. #WPA2 with #Freifunk worked fine, however we could not login to #eduroam and found out that our documentation needs some care. Please share your knowledge in our #wiki.
Should we organize a #GentooWorkshop and configure eduroam together and improve the wiki?
Let us know via Mastodon, Mail, IRC, or a postcard.

I deal with a lot of technology challenges through my day job, but none more frustrating than trying to get a home network, all its devices, and internet connections to just work.
So much of my life I’m never getting back.

Mood du jour :
On a la fibre WEEEEEE !🥳
Au sous-sol Oooooooooh 😥
L'ancien propriétaire avait son bureau dans la cave.
Nous on veut pouvoir bosser en rez-de-chaussée et l'ado dans son pigeonnier sous les combles.
On trouve des répéteurs ou vous auriez une autre solution les gens des internets ?
Me dites pas de tout péter, je suis déjà tentée 😆

📡 EVIL TWIN

Una rete Wi-Fi può sembrare quella ufficiale, ma essere una copia creata da un attaccante. Con un “Evil Twin” si tenta di convincere gli utenti a collegarsi al falso Access Point per intercettare o manipolare le comunicazioni.

SSID identico ≠ rete affidabile.

Как определить местоположение людей по Wi-Fi: BIM и семантика повышают точность

Можно ли повысить точность определения положения людей в помещении, опираясь только на инфраструктуру Wi-Fi, если дополнить её BIM-данными и семантикой использования помещений? Рассказываю о том, что мы с коллегами напроверяли, как решали задачу и какие результаты получили в очередном проекте.

Yes, yes, it is. #WiFi 7 for the win.
