Troubleshooting

Unable to detect LAN network from ground module

In case you can't see that the LAN network from ground module was detected and established, then you would need to install the driver:

You can find the latest drivers from Realtek available here.

In some cases you might need to disable ’system integrity protection’ and then instal the driver For instance, here is the demo video on how to disable SIP on Mac OS.

Unable to Ping smartlink.local - Unknown Host

Some operating systems might not have local DNS, resulting in the inability to access the system using the name (smartlink.local). This is known for all Android platforms and some Windows platforms. In case you can't ping smartlink.local or similar:

ping: cannot resolve smartlink.local: Unknown host

You'll need to find out the IP address for SmartLink. There are numerous ways to do this, we'll use the NMAP tool in this example. First of all, download and install NMAP tool using the relevant links below:

Linux

sudo apt-get install nmap

Mac OS

brew install nmap

Windows

Go to the official website for NMAP tool: Nmap web page

Select Latest stable release self-installer: nmap-7.80-setup.exe or similar. Download and install it.

Make sure to select Install Npcap in WinPcap API-compatible mode during the installation.

After installation is complete, open command line and go to NMAP folder:

cd "C:\Program Files (x86)\Nmap"

Looking up SmartLink's IP Address

Execute IP addresses scan within the required range, in our case it will be:

nmap 192.168.168.*

As a result of this command you'll see IP addresses in this range. You'll have 192.168.168.1 which is, as a rule, configured as air module, 192.168.168.2 which is usually configured as ground module and 192.168.168.x (x: 0-255) which is the IP address for SmartLink. You should use this IP address - 192.168.168.x for direct connection instead of smartlink.local.

No Internet Connection when SmartLink is Plugged into USB Port

Sometimes you might not be connected to the internet after SmartLink is plugged into the USB port and detected. SmartLink is identified as LAN connection and sometimes the operating system expects this to be a primary connection for accessing the internet. It is in fact not. You still have to use your LAN / WLAN for internet access and this has to be set in the operating system.

Do the following actions to enable internet access while SmartLink is connected:

Windows

Follow the steps from this tutorial to change the MTU value for network connections:

A lower MTU value means higher priority for the interface. Therefore, you need to have the MTU value set lower for your LAN / WLAN network than for SmartLink networks

Linux

Open command line and execute the following command:

sudo ip route del default

Mac OS

Go to network connections menu and make sure that the Service Order is set higher for your LAN / WLAN connection but not SmartLink:
