Checking if network is up before you try to ftp will not help if the network goes while a transfer is happening.
I don't know how long a ftp-client usually "hangs" until it receives a timeout and if it really spits out a return code >1 in that case (it should). Different ftp-clients might have different options for this.
ftp is not encrypted and unsecure - maybe switch to ssh/scp/sftp and set up public key authentication, if it is an option. You would also not have to write clear passwords in a file.
You can use helpful options with scp for example like:
see man scp.
You can script a lot of things around it to make it more waterproof for your problem case, but generally I'd say you should try to solve that network problem as priority and implement the ssh/scp/sftp protocol suite.

curlopt_ftpport
CURLOPT_FTPPORT(3) curl_easy_setopt options CURLOPT_FTPPORT(3)NAME
CURLOPT_FTPPORT - make FTP transfer active
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTPPORT, char *spec);
DESCRIPTION
Pass a pointer to a zero terminated string as parameter. It specifies that the FTP transfer will be made actively and the given string will
be used to get the IP address to use for the FTP PORT instruction.
The PORT instruction tells the remote server to connect to our specified IP address. The string may be a plain IP address, a host name, a
network interface name (under Unix) or just a '-' symbol to let the library use your system's default IP address. Default FTP operations
are passive, and thus won't use PORT.
The address can be followed by a ':' to specify a port, optionally followed by a '-' to specify a port range. If the port specified is 0,
the operating system will pick a free port. If a range is provided and all ports in the range are not available, libcurl will report
CURLE_FTP_PORT_FAILED for the handle. Invalid port/range settings are ignored. IPv6 addresses followed by a port or portrange have to be
in brackets. IPv6 addresses without port/range specifier can be in brackets.
Examples with specified ports:
eth0:0
192.168.1.2:32000-33000
curl.se:32123
[::1]:1234-4567
You disable PORT again and go back to using the passive version by setting this option to NULL.
The application does not have to keep the string around after setting this option.
DEFAULT
NULL
PROTOCOLS
FTP
EXAMPLE
TODO
AVAILABILITY
Port range support was added in 7.19.5
RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
