This option is typically used for DSL services. Some DSL service providers supply a
special DSL modem. This kind of modem only supports the PPTP tunnel to access the
Internet, you should create a PPTP tunnel that carries a PPP session and terminates on
the DSL model. Once the tunnel has been established, this kind of DSL modem will
forward the PPP session to the ISP. As long as the PPP session is connected, all the local
users will be able to share this PPP session to access to the Internet.
Apply 3G or 3.5G transmission rate for the backup. Once DHCP Client connection is

is not available, it starts to search downward for 3/2.75/2.5G signals until none existed.
