If SSH is refusing the connection, make sure you have "PermitRootLogin yes" in the config file if you're logging in with the root account. SSH blocks the root user from logging in by default. Or if you don't want to log in as root, make sure the user accounts on the TS-7300 are set up the same as they were on your TS-7800. If you were using SSH keys instead of typing the password when logging in, you'll want to make sure the key files have been moved over as well (or generate new ones).
Windows firewall (or similar firewall/antivirus software) could potentially be blocking you from pinging from device to host. You could try pinging something known to work, like Google, or your local gateway. But if you're getting a connection refused message instead of connection timed out, it sounds like SSH is successfully connecting and then terminating the connection because of a credentials issue.

Using ifconfig I reset the address to 192.168.0.50 and am now able to sucessfully ping my device from my host machine. However, I'm unable to ping my host from the device. In addition, when I attempt to SSH in I'm given the error "Connection Refused". I turned off my firewall thinking that could be it but that didn't solve it. I then compared it to my working TS-7800 using ifconfig on both. The TS-7800
is sending and recieving packets:
RX packets:52 errors:0 dropped:0 overruns:0 frame:0
TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:256
RX bytes:4928 (4.8 KiB) TX bytes:380 (380.0 b)
Interrupt:21
The 7300 however is not:
RX packets:149 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:39
The /etc/ssh/ssh_config files were slightly different so I modified the 7300 to match but this failed as well. The fact that I can ping it but not connect to it makes me think its definitely an issue on the device side.
