WEP WiFi Hotspot

Question

So I want to use my DS online again, and what I need to do is get a router with WEP seurity, or a router without security. So I decided to use my Pi 3 B as a WiFi hotspot. But all the stuff I find is for WPA and the like. Is there a way to make a hotspot without security or a WEP security?

Thanks!

Take a look at hostapd config file options. I've stripped out the bits for WEP.

# IEEE 802.11 specifies two authentication algorithms. hostapd can be
# configured to allow both of these or only one. Open system authentication
# should be used with IEEE 802.1X.
# Bit fields of allowed authentication algorithms:
# bit 0 = Open System Authentication
# bit 1 = Shared Key Authentication (requires WEP)
# Use either
auth_algs=3
#or auth_algs=2
#
# Static WEP key configuration
#
# The key number to use when transmitting.
# It must be between 0 and 3, and the corresponding key must be set.
# default: not set
#
wep_default_key=0
#
# The WEP keys to use.
# A key may be a quoted string or unquoted hexadecimal digits.
# The key length should be 5, 13, or 16 characters, or 10, 26, or 32
# digits, depending on whether 40-bit (64-bit), 104-bit (128-bit), or
# 128-bit (152-bit) WEP is used.
# Only the default key must be supplied; the others are optional.
# default: not set
wep_key0=123456789a
#wep_key1="vwxyz"
#wep_key2=0102030405060708090a0b0c0d
#wep_key3=".2.4.6.8.0.23"
#
# WEP rekeying (disabled if key lengths are not set or are set to 0)
# Key lengths for default/broadcast and individual/unicast keys:
# 5 = 40-bit WEP (also known as 64-bit WEP with 40 secret bits)
# 13 = 104-bit WEP (also known as 128-bit WEP with 104 secret bits)
#wep_key_len_broadcast=5
#wep_key_len_unicast=5
# Rekeying period in seconds. 0 = do not rekey (i.e., set keys only once)
#wep_rekey_period=300

Should get your AP doing the ancient, insecure protocol that your Nintendo DS needs.

To use none security or to use WEP security you have just to configure wpa_supplicant in /etc/wpa_supplicant/wpa_supplicant*.conf. For example I take Setting up a Raspberry Pi as an access point - the easy way in section Configure wpa_supplicant as access point. Just use this configuration for an unsecured access point:

cat > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
country=DE
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="RPiNet"
    mode=2
    key_mgmt=NONE
    frequency=2437
}

For a WEP secured connection you can look at

zcat /usr/share/doc/wpa_supplicant/examples/wpa_supplicant.conf.gz | less

There you will find two examples for a network block nearly the end:

# Shared WEP key connection (no WPA, no IEEE 802.1X)
network={
        ssid="static-wep-test"
        key_mgmt=NONE
        wep_key0="abcde"
        wep_key1=0102030405
        wep_key2="1234567890123"
        wep_tx_keyidx=0
        priority=5
}


# Shared WEP key connection (no WPA, no IEEE 802.1X) using Shared Key
# IEEE 802.11 authentication
network={
        ssid="static-wep-test2"
        key_mgmt=NONE
        wep_key0="abcde"
        wep_key1=0102030405
        wep_key2="1234567890123"
        wep_tx_keyidx=0
        priority=5
        auth_alg=SHARED
}

I haven't tested it but I think for an access point you have to add mode=2 and a frequency= line.
