TS-4900 Wifi Access Point

First install hostapd to manage the access point:

apt-get update && apt-get install hostapd -y

Edit /etc/hostapd/hostapd.conf to include:

interface=wlan0
driver=nl80211
ssid=YourAPName
channel=1

Note:

Refer to the kernel's hostapd documentation for more wireless configuration options.

To start the access point launch hostapd:

hostapd /etc/hostapd/hostapd.conf &

This will create a valid wireless access point, however many devices will not be able to connect without either a static connection, or a DHCP server. Refer to Debian's documentation for more details on DHCP configuration.
