A question about mobile hotspots

Quote16 · June 18, 2016

This is an exact quote from my post to my xda post that nobody responded to. The g3 and g4 are referencing the lg g3 and g4

So as you may or may not know, at&t doesn't allow their customers to hotspot from their phones without paying some fee or something. My g3 is rooted and I've been on fulmics ROM for a long time. The weird thing is that I can use the hotspot feature without restriction. How does all the hotspot stuff work? My home WiFi sucks and basically I have the best WiFi in the house because of my phone (and I use it for my PC)

My brother has an at&t g4 and I was wondering if he would be able to use his hotspot without restriction just because he's on a custom ROM. Any insight on this?

Hostapd turns your phone's WiFi adapter (wlan0) into master mode to broadcast an access point then Dnsmasq runs a DHCP and DNS server to assign addresses to any clients then all the traffic gets forwarded out your cellular connection through IPtables. You can do the exact same thing using any Linux distro. See for yourself by opening a root terminal and running -

ps to show Dnsmasq and Hostapd processes.
nestat -tuln to show open ports 53 and 67 (DNS/DHCP).
iptables -nvL to show iptable rules.

I wish I knew what you're talking about but I'm not familiafamiliar with Linux itself at all. I was just asking if a ROM could enable the hotspot functionality on his g4
