TPLink WA701ND v2.0 - Router DHCP enabled Wireless mode

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello, I have a TP-Link TL-WA701ND v2.0 router with the latest version of OpenWRT.

This router has only 1 ETH port.

Anyone can share the configuration for the Router use case:

My OpenWRT
1eth port - LAN --> connect to a switch and receives de internet (192.168.1.1)
Wireless --> DHCP enabled and received internet from LAN network.

To resume, I want this AP, act like a standard wireless router.

Thanks

So you want this:

  • WAN - wired interface, dynamic IP-address, DHCP+DHCPv6 client, NAT
  • LAN - wireless interface, static IP-address, DHCP+DHCPv6 server

Is that correct?

Yes, that’s correct

Separating WLAN interface/network:

uci set dhcp.wlan="dhcp"
uci set dhcp.wlan.interface="wlan"
uci set dhcp.wlan.start="100"
uci set dhcp.wlan.limit="150"
uci set dhcp.wlan.leasetime="12h"
uci set dhcp.wlan.dhcpv6="server"
uci set dhcp.wlan.ra="server"
uci add_list firewall.@zone[0].network="wlan"
uci set wireless.default_radio0.network="wlan"
uci set network.wlan="interface"
uci set network.wlan.proto="static"
uci set network.wlan.ipaddr="192.168.2.1"
uci set network.wlan.netmask="255.255.255.0"
uci set network.wlan.ip6assign="60"
uci commit dhcp
uci commit firewall
uci commit wireless
uci commit network
service dnsmasq restart
service firewall restart
service network restart

Verify, that you can accomplish the following:

  • Connect to the wireless network.
  • Receive an IP-address from 192.168.2.0/24 subnet.
  • Access OpenWrt (192.168.2.1) via HTTP/SSH.

Proceed only in case verification is succeessful.
Configuring WAN interface:

uci delete dhcp.lan
uci delete network.lan
uci set network.wan="interface"
uci set network.wan.ifname="eth0"
uci set network.wan.proto="dhcp"
uci set network.wan6="interface"
uci set network.wan6.ifname="eth0"
uci set network.wan6.proto="dhcpv6"
uci set network.wan6.reqaddress="try"
uci set network.wan6.reqprefix="auto"
uci commit dhcp
uci commit network
service dnsmasq restart
service firewall restart
service network restart
