A setting called 'client isolation' on a router will prevent a computer that connects to a wifi network from accessing computers (and other devices) that are on the same network with wired connections. This is very useful if you plan on having visitors use a network set-up for the use of attorneys from your firm.
The client isolation setting will also prevent two devices connected to the network via wifi from connecting with one another.
Client isolation (also known as wireless isolation) differs from guest wifi networks which involve an entirely separate access point. Client isolation uses firewalls to restrict visitors to connecting to the internet.
Each device on the internet needs an IP address. The current version of the Internet Protocol is IPv6, which replaced IPv4, which was limited to fewer than 5 billion variations. IPv4 was in the format many are familiar with: four numbers separated by periods. For example:
An IPv6 address will consists of eight strings of four hexadecimal digits [0-9, and A-F] - each divided by a colon. But leading zeroes, or strings of all zeros are omitted. So, an example of a IPv6 address would be:
. . . the complete version of which would be 2001:4998:0124:1507:0000:0000:0000:f000
In the United States, most mobile phones use an IPv6 address, but only a small percentage of computers do.
Keep in mind that most people will operate travel routers through an app on their smartphones. So in order to make this work, you connect your phone to the wifi network for the router. This will initially mean that the phone will be temporarily offline, if you are using the travel router as a bridge for wifi, and not as an access point with an ethernet cable plugged into the travel router run from a modem.
Use the app for the travel router to connect to the wifi network in your workspace - NOT the regular system settings on your iPhone or Android. This will not only allow the travel router to act as a bridge for other devices that want to use the travel router's extended wifi network, but it will also put your phone back online.
Bridge mode wifi speed will be 50% of the wifi speed available when the travel router is used as an access point.
