Dear all,

I'm writing this topic to ask you suggestions regarding an issue with my device.

 

I have an ISP modem, and I'd like to use AC1600 as an access point to extend the wifi coverage.

 

This is what I tried so far. I'll label the AC1600 as "AP" and the ISP modem as "modem"

 

First attempt

1. Assign static ip to AP 192.168.1.250/24

2. Disable dhcp for AP

3. Modem is default gateway at 192.168.1.1/24

4. Add dhcp static configuration to modem to assign always the same ip to the AP

5. Connect the AP lan 1 interface to the modem Ethernet port

6. Configure AP wifi settings to broadcast the same ssid and configure same WPA2 key as the modem

7. Default operation mode is DSL modem router

 

Result

A. AP can be reached through its ip 

B. Devices connected to AP wifi CAN'T access the network

C. Devices connected to AP lan interface CAN access the network

 

 

Attempt 2

1. Same configuration as above

2. Connect modem lan interface to AP at port LAN4/Wan

3. Set operation mode as wireless router

 

Result

A. Although from the manual it says that the AP will share the connection coming to LAN4 port, devices connected to wifi can't access the network

B. AP is no longer reachable through its ip address

 

I'm clueless about what I could try more or what I'm doing wrong.

 

Can you please help? Any suggestion will be appreciated

 

I thought to try to subnet the network, with a network for modem and a network for access point. Then set a default route to modem. But I would like discard this idea to reduce network complexity

Update:

 

 

I tried the following:

 

Disable dhcp on AP

Set AP ip address to 192.168.1.250

Set dhcp rule to assign always the same ip to the AP

Connected ethernet cable from modem lan interface to AP LAN1

Set mode to Wireless Router

 

Now the devices connected to AP wifi interface can access the internet, but I lost access to AP web interface.

The AP can't be found in the list of connected devices, nor it can be reached from its ip address.

Furthermore, ping to the AP results to time out error.

 

What happened?

Try the following:

Same settings as attempt 2, but connect modem to AP LAN1 port again. Set AP LAN static IP address 192.168.1.250.

Set the AP SSIDs different for the troubleshooting purposes (you'll know to which device mode/AP you're connected).

If that doesn't work you don't have any other useful option except introducing double NAT (original Attempt 2 but with AP DHCP enabled) - using AP as a wireless router.
