troubleshoot `internet_connection` function

Currently, it checks the IP address of the current machine. Not sure that actually checks if there's an active internet connection:
```python
def internet_connection():
"""Test internet connection - not clear if that's actually what's happening here"""

# get current IP address of system
ipaddress = socket.gethostbyname(socket.gethostname())

# checking system IP is the same as "127.0.0.1" or not.
if ipaddress == "127.0.0.1": # no internet
return False, ipaddress
else:
return True, ipaddress
```

maybe this instead?
```python
def check_internet():
try:
res = socket.getaddrinfo('google.com',80)
return True
except:
return False
```

Start at the `internet_connection` function shown in the issue and inspect how its return value is used. Compare the current localhost check with the proposed connectivity check, then define and test the expected behavior for reachable and unavailable networks; done means the function’s result matches that behavior.
