Q. I am trying to log into the repeater but the web browser displays “This site can’t be reached”, why?

A. First thing to check when unsure if your laptop is communicating with the repeater is to open Command Prompt (search for or run “CMD”). When Command prompt is open, type the following: “ping” and hit enter. If you are successfully pinging the repeater’s IP address, Command Prompt will display “Packets: Sent = 4, Received = 4, Lost = 0” among other information. If you successfully ping the repeater but are unable to login through a web browser, check your firewall settings or try a different browser.

Q. I am unable to ping the repeater’s IP address, why?

A. If you are unable to ping the repeater’s IP address through Command Prompt, you may need to set your laptop’s IPV4 to a static IP address. To do this, open your “network and sharing center” through your control panel. This will be different depending on your laptop’s operating system, but with windows, you will see a link for “change adapter settings”. The next page will display an icon for your “local area connection” or “ethernet”. You will need to Right click on this icon and select “properties”. A small screen will pop up and you will need to scroll down and select “Internet Protocol Version 4 (TCP/IPv4)” Once selected, you will need to click the “properties” button below. A new small screen will pop up beginning on the “General” tab. Select the bubble for “Use the following IP address” and type in an IP address within the range of the repeater’s IP address (but not the same IP address). In this case, you will want to set your laptop to an IP Address such as: “”. After filling in the IP address, you can hit the “tab” button on your keyboard and it will automatically put in a subnet mask of “”. You can leave everything else along on this screen and hit “OK” at the bottom to apply these changes. In some cases, you may need to restart your laptop for these changes to take effect.

Q. I am able to ping the repeater but I cannot get to the login screen through a browser, why?

A. When logging into the repeater, you will need to include HTTPS:// before the IP address
i.e. HTTPS://
When connecting to this repeater for the first time on some laptops/browsers, it will look like you still do not have a connection to the repeater. For example, on Google Chrome, after putting in the IP, you will see an “advanced” button which will have an option to “proceed anyway”. You may also need to set your laptop’s IPV4 to a static IP address.

Q. My Downlink output power is displaying higher than the set ALC limit, why?

A. This can happen when your input signal (Downlink RSSI) is too strong on either CDMA, LTE1, or LTE2. GST recommends you contact tech support for turning on “Fixed Gain” if CDMA, LTE1, or LTE2 Downlink RSSI is stronger than -36

Q. How will I know what to set my “ALC Values” to for Uplink/Downlink?

A. This is a 20 watt output power repeater with 2 watts uplink power. When setting the “ALC Value” you will need to make sure that your overall ALC Value settings do not exceed the repeater limitations. For example, if you are using CDMA, LTE1, LTE2, you can set CDMA to 40 dBm (10 watts) while LTE1 and LTE2 are each set to 37 dBm (5 watts each) for a total of 20 watts downlink output power. On the other hand, for Uplink you will have CDMA set to 30 dBm (1 watt) while LTE1 and LTE2 are each set to 27 dBm (0.5 watts each) for a total of 2 watts uplink power.
