Misc 3DS won't find hostapd hotspot

[mid-kid]

I'm trying to create a hotspot with my computer for my 3DS.
OS is Funtoo, with dnsmasq 2.72 and hostapd 2.0.
I think I've set it up correctly, but my 3DS can't see the hotspot, while my laptop can, and connection works.
Configuring the network manually on the 3DS doesn't work either.
An ethernet cable is connected to the router, and I've got a USB dongle (Realtek RTL8188CUS) to create the hotspot.

These are my configuration files.

dnsmasq.conf:

no-resolv
interface=wlan0
dhcp-range=10.0.0.3,10.0.0.20,12h
server=8.8.8.8
server=8.8.4.4

hostapd.conf:

interface=wlan0
driver=nl80211
ssid=waffles
hw_mode=g
channel=1
wpa=0

start.sh:

#!/bin/bash
set -e
 
ifconfig wlan0 down
ifconfig wlan0 up 10.0.0.1 netmask 255.255.255.0
sleep 2
 
dnsmasq -C ./dnsmasq.conf
 
iptables --flush
iptables --table nat --flush
iptables --delete-chain
iptables --table nat --delete-chain
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface wlan0 -j ACCEPT
 
echo 1 > /proc/sys/net/ipv4/ip_forward
 
hostapd ./hostapd.conf -d
killall dnsmasq

I hope somebody can point out where I went wrong.

The 3DS should support b and g mode, but try the configfile with hw_mode=b.

Thanks for the quick reply, but my 3DS can't find the AP with that mode either.

Maybe try another driver? rt1871xdrv should work as well with the chipset.
I think the source of the problem is the hostapd config.

Many thanks to you, dear sir. This method worked.

Here's what I did:
I downloaded hostapd 2.2 and followed the installation instructions for the driver. (I left the source and compiled files under the hostapd-2.2 directory, as can be seen in start.sh, soon to follow)
Next, I followed the installation instructions for the kernel module. (Keep in mind where make installed the module in case you want to remove it.).
I did "rmmod <module>" for every module in this list and their dependencies, and modprobed the recently installed module.
Then, I altered the configurations a bit:

hostapd.conf:

interface=wlan0
driver=rtl871xdrv
device_name=RTL8192CU
manufacturer=Realtek
ssid=waffles
hw_mode=g
ieee80211n=1
channel=1
wpa=0

start.sh:

Line 19: ./hostapd-2.2/hostapd/hostapd ./hostapd.conf -d

Now the hotspot can be seen by the 3DS.
