post thoughts or questions about wireless technology here. 802.11, 802.15.4, SDR, HAM, Mesh nets, dark nets, VANETs, whatever
(Not trolling) But, what's the difference between 802.11 and 802.15.4?
What's a Mesh net?
What's a VANET?
this thread would have been cool bro I want to learn abut wireless technologies.

Agreed in full!

.15.4

what kind of measurement is that is that?
.15.4 what
I'll start

contrast your wifi, cellular phone, bluetooth, whatever networks where there is
>infrastructure (router, access point, station)
>clients (devices, radios, adapters)
in an ad-hoc network, there are only clients. The devices (in this analogy your computers, phones, etc) all send and receive data amongst themselves, instead of communicating individually with a central/shared access point.
A mesh network is a type of ad-hoc network which is dynamic. As devices come on and offline, move about, enter and leave each other's transmit/receive range, the network topology changes. Ideally, any client device which is in range of just one other device, can access the entire network, with data "hopping" between clients until it reaches the desired endpoint.
Additionally, in large deployments these networks may self-organize routing in order to optimize bandwidth, latency, or some other metric.

Wow, that's really informative! Thank you. I mean it.
Hope this is in scope but
Sometimes my internet connection behaves very weird, how can I debug it, in general? Like getting all the possible information out of every interaction with the router, including authentication and dhcp lease acquisition?
Also I ran nmap on what seemed to be the router and it didn't find any ports open, do you think it's using an uncommon port for obscurity?
