My router broke down(ordered another but it will take weeks to arrive) so I had to setup an old netbook to do the job temporarily. It's running Windows 10's(I couldn't get hotspots working on Linux) native hotspot program. I can connect game consoles, phones and computers(the limit seems to be 100 devices, and I had 5 devices connected at once), but not this one laptop. I know the networking works because I'm using my Android's hotspot ATM.
Now this laptop is running Arch, tried Netctl, Wicd and NetworkManager and the two former connected to the hotspot but couldn't obtain IP address. I then tried some live disks I had laying around(Kali and Mint) and both had the same problem as Arch.

(it is connected right now to a different hotspot)
$ iptables -S -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT
Tried ifconfig up / down, iwconfig power off, played around with modprobe configs(deleted now)...
The settings of the hotspot seem fairly standard, nothing Linux would have problems with(since Android and PS4 are fine with it).
I'm not sure which logs or outputs exactly would be helpful in this situation...
