Linux wireless repeater (range extender)

Hi,

I want to use my old laptop as a wireless range extender (temporary).

Can anybody point me to any step-by step instruction for Linux?

Thanks

Here is my solution using NAT (wireless bridge is not possible)

Code:

# create virtual wlan adapter and run HostAP
iw phy phy0 interface add hostap.wlan1 type managed
ifconfig hostap.wlan1 down
ifconfig hostap.wlan1 hw ether 12:34:56:78:90:ab
ifconfig hostap.wlan1 192.168.0.1 up
hostapd /etc/hostapd.conf -B

# start DHCP and DNS
systemctl start dhcpd.service
systemctl start named.service

# connect to upstream AP
wpa_supplicant -D wext -i wlan0 -c /etc/wpa.conf -B
dhcpcd wlan0

# enable NAT
iptables --table nat --append POSTROUTING --out-interface wlan0 -j MASQUERADE
iptables --append FORWARD --in-interface hostap.wlan1 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward

Hope this helps
