Assuming your network has two routers:

1. The main router a Netgear Nighthawk AC1900 Cable Modem Router Model C7000v2 that supports a LAN network 10.0.0.x

2. A TP-Link Archer C50 V2 that you want to configure as a wireless access point to 10.0.0.x

3. a network switch or hub that connects to your main router network

1. Reserve an address in the DHCP of your main router, C7000. In my case I chose 10.0.0.21.

2. Copy down all the information from the label on your C50

   1. mac address

   2. default user

   3. default user password

3. Download the latest firmware for the TP-Link Archer C50 V2 from www.TP-Link.com The version installed in my TP-Link Archer C50 V2 is Archer_C50v2_0.8.0_0.3_up_boot(160801)_2016-08-01_20.23.51.bin

4. reset C50 to factory defaults

5. configure the PC to the default C50 network established by factory reset

   1. set pc wired adapter to static ip 192.168.0.2 subnet mask 255.255.255.0

   2. cable pc to C50 connecting to one of the "orange", non-internet ports on the C50

6. connect to C50

   1. use a browser on the pc to access http://192.168.0.1

   2. log in to C50 using default admin credentials from step 2 above

   3. install the latest firmware downloaded in step 1.

   4. set admin user to admin

   5. set admin password to whatever you desire. I used 19Basement

   6. set C50 LAN address to an address and subnet on the LAN on your main router, C7000. I used 10.0.0.21 and 255.255.255.0.

   7. reboot C50

7. reconfigured PC to dynamic ip and plug switch/hub connected to your main network

8. Connect C50 to C7000 network by cabling non-internet port, orange port, to switch

   1. on your pc use a browser to connect to C50 at address you chose in step 6.f above. I used 10.0.0.21.

   2. Log in to admin app using credentials you set in steps 6.d and 6.e above. I used: admin,19Basement.

   3. Go to basic->wireless password and set passwords for wireless networks on C50. I used 19757519. Note you can also set the SIDS. I chose to leave the defaults.

   4. Go to advanced->network->DHCP. Set DHCP enabled and DHCP relay. Set the relay address to the address of your main router. In my case 10.0.0.1,255.255.255.0.

   5. Go to advanced->network->internet. Verify setting is dynamic. Correct if necessary.

   6. Go to advanced->network->Lan Verify setting is the one you chose in step 6.f. I used 10.0.0.21, 255.255.255.0.  WARNING - if you need to correct this C50 will reboot. Your settings may be lost and you need to go back to step 4.

9. Verify that a non-internet port on C50, orange port, is cabled to the C7000 wired network through the switch.

10. reset all PC adapters to ip from DHCP and plug your PC into the network switch.

At his point the C50 should be acting as a wireless access point for the main router, C7000.

Verify C50 is running as access point.

From your PC you should see two wireless networks broadcast by the C50. Connect to one of them.

Disable the wired Ethernet adapter in your PC. Use the PC ipconfig utility to verify you are connected to the network you set in step 6.f. I used 10.0.0.21, 255.255.255.0. Use the ping utility to ping any machine on that network including the C50 at the address you chose. I used 10.0.0.21.

Enable the wired Ethernet adapter in your PC. Disconnect from the wireless network and disable the wireless Ethernet adapter in your PC. Use the PC ipconfig utility to verify you are connected to the network you set in step 6.f. I used 10.0.0.21, 255.255.255.0. Use the ping utility to ping any machine on that network including the C50 at the address you chose. I used 10.0.0.21.

Reenable and reset the ethernet adapters on our PC>
