Troubleshooting Wi-Fi connectivity errors
This article covers common issues and errors that end users may face when attempting to connect a Mobile Link device to their home network.
Environment
Note: Upgrading to the Connectivity Cellular Accessory is recommended for users who wish to add connectivity to their generator or are experiencing ongoing connectivity issues. It is compatible with more generators and uses multiple carrier networks to offer greater coverage. Basic (free) and Premium cellular plans are available. See here to upgrade: Connectivity Cellular Accessory.
Before you begin: consider configuring a dedicated 2.4 GHz network
Generac support has found that many connection issues are resolved by configuring a dedicated 2.4 GHz Wi-Fi network on the router. Before proceeding with in-depth troubleshooting, verify that the home Wi-Fi network is compatible with Mobile Link: Is My Wi-Fi Network Compatible With Mobile Link?
Common issues
Dual-band routers
If using a dual-band router, ensure the 2.4 GHz network is selected during setup. A dedicated 2.4 GHz network is preferred. See: Is My Wi-Fi Network Compatible With Mobile Link?
Wrong passcode
This can indicate weak signal strength. To resolve:
Low or no signal percentages
Wi-Fi Signal 0%
This may indicate extremely low signal strength, a mesh/5 GHz network, or an incompatible setup. Try the following:
- Contact your ISP about splitting 2.4 GHz and 5 GHz bands.
- Use a 2.4 GHz-only extender.
- Confirm there is no ISP outage.
Low Wi-Fi Signal
- Check generator-to-router distance. If over 25 feet, move router or add extender.
- Minimize physical obstructions between router and generator.
- Repeat the connection process after repositioning equipment.

Low bandwidth
Low bandwidth can be caused by heavy home internet usage. High-data devices include:
- Security systems (smart doorbells or cameras)
- Streaming devices
- Online gaming
MLG network is connected, but app and IP address will not load
Try the following if setup is stuck after connecting to the MLG network:
- Verify phone is connected to MLG network.
- Disconnect and reconnect to MLG.
- Use a different smart device.
- Power cycle the generator.
- Reset the router and extender (if used).
The control panel says ‘Bad/No SSID’
This is likely a router provisioning issue. Try power cycling the router. For hidden SSIDs, see: How do I connect a Mobile Link device to my home network if my SSID is hidden?
Network ports
Mobile Link uses common ports (8080, 8081, 443, 123, 53). These are open on most home routers by default and are rarely the issue.
Notifications not updating or status mismatch
