Verizon 4G LTE Samsung Wireless on Debian

In order to get access to the wireless hotspot you will probably need a Windows laptop as the encryption method was not available for Linux on the laptop used. Use a Windows connection and point to 192.168.1.1 and login using the password that is located on the device.

Once you login you have three tabs, Network, Security and

Configuration. The basic information is listed on the opening page.

Internet Connection

Under the Network tab you have information about the InternetConnectivity. Note some IP Addresses have been removed for security. This interface provides network traffic information as well as the IP Address that you are on externally. The Gateway for your connection is also listed. Note the "Mask: is for one IP for security sake. The DNS server that is in use is also there.

WLAN

The profile is Secure is that is all that really makes sense especially if you are traveling. The security type is where you may have issues if you have a Linux machine with a wireless card. Here you can see the wireless security listed as WPA2-AES which probably will provide excellent protection and work with Linux. The Network Name will be listed with the IP Address that is used for the device.

Select Network and LAN to see change the IP Address for the wireless hotspot. You will see the MAC Address listed as well if you needed that (removed for security here).

DHCP Server

You can limit the IPs that will be available on the network as well as change the Mask and Gateway. It makes sense to limit access but the fact is this hotspot will not support many users anyway. If you change the wireless IP Address on the hotspot be sure to modify the Gateway and DNS Server settings.

Select the WiFi tab and then Manual Configuration. This is where you will need to make changes to connect using Linux. Change the Security to WPA2 (AES) as you see on the screen and enter a password to connect. This password is what you will use to set up the Linux laptop to connect automatically. The mode may have to be changed to b if you have an old wireless card but basically you should have g capability or you would not get the 4G connection.

The Security tab allows you to change the password, be sure to remember that password. It also allows you to filter MAC addresses. MAC addresses are the imprinted hardware addresses on every network interface that is placed there by the manufacturer. This are unique. MAC filtering will provide additional security if you need it.

Below is the example of MAC filtering.

Port Filtering allows you to control access to the Internet frominternal ports. This way if it is enabled you will be able to control access to the Internet.

The Configuration tab provides 4 additional tabs.

Settings

Basic settings for automatic connecting and roaming are available Probably you will not make any changes on this page.

Diagnostics

There are several options to test the device.

Port Forwarding

The Port Forwading will allow your firewall to forward connections to external ports to internal machines that you have on the network. This may be a way to provide access to another machine that you need to allow a connection to to transfer data for example. This would allow you to set up an SSH connection or FTP server to transfer files.

Power

You can manage power issues from this option which are especially important if you are using the device without a power connection.

Once you have your the 4G Samsung set up then you will need to set up the Linux laptop that you will use with it. You will need to have the wireless drivers set up on the device and you will need to edit /etc/network/interfaces. This file will link up to the wireless hotstpot when you start it. Be sure to enter the full SSID, the verison is truncated in the example. The password that you use will be the password on the wireless hotspot which is on the label. When you boot the laptop it should automatically connect up.
