Model: CPE210  
Hardware Version: V2
Firmware Version: 2

Just purchase 2 CPE210 units to extend my office wifi to a building across the parking lot. I believe I have everything set up properly but I am having trouble with a specific deivce I need to connect to the client mode unit. When I connect my laptop to the client mode unit with an ethernet cable and setting my IP to DHCP I am able to connect to the internet. However when I switch my laptop to static IP I no longer have an internet connection. Similarly the device I wish to connect to the client mode unit (campbell Scientific data logger) is not able to connect to the internet. I would like to be able to set a static ip on my special device (datalogger) and have it connected to the internet. The datalogger works correctly when connected directly to the building network. It does not work correclty when connected to the client mode unit. What changes do I need to make in the settings of the client mode unit to allow my device to connect to the internet?

Hi  @Esully565 

 

Thanks for posting here.

>>>This indicates the wireless bridge is working correctly.

 

The issue is likely with your static IP configuration. Please ensure that the static IP you configured falls within the DHCP address pool of the office wifi. Or you can configure DHCP reservation on the office router for the datalogger.

For easier management, we also recommend setting the CPE's IP address in the same subnet.

After some more configuration I was able to get things working. I think I was missing the DNS settings. However I have encountered a new issue. At this point I have a good connection to the internet when using the two CPE210 units. Each CPE210 has a valid static IP address configuration. When I connect my laptop I am able to connect with both static and DHCP. Previously I was missing the DNS info. However, I have noticed some strange behavior. The device I intend to connect to has a fixed IP address of 10.104.82.172. This device does have access to the internet when doing a ping to 8.8.8.8. I am able to use my laptop to ping the device after it has successfully connected to the internet. But after about 1 minute of inactivity the device becomes unreachable.  I do not have a way to make the device constantly perform an outbound network connection. The device does not have a firewall. This problem only occurs when the subnets do not match. Is there a setting in the CPE210 that I can use to make sure the device can be reached?
