When I log into SWTOR Character, it takes me back to server selection screen?

I am sorry for the late reply. I have been busy for the past week and did not have much of a chance to get onto the game to test out the changes.

When I did eventually log on and seriously play for a few hours, I can report that there were no interruptions with the connection. This was after I followed what @proxos666 had said and checked the cable that connected my computer to the wall. In addition, I rebooted my internet and checked the wire and it seemed to work.

Since the few times I've played it, I did not run into any serious problems with connection, I am going to mark this thread as solved. However, just in case anybody else is having this problem (and this thread is found in the future -- because trust me, I've been there looking at old threads for this sort of stuff), I'll just detail what I did / others suggested on this final post.

When I couldn't literally log onto my character AT ALL:

• I came here and was able to get in touch with an admin to reset my character onto the Fleet. [Worked]. 
• Uninstalled / Reinstalled SWTOR [Moderate Success]
• Updated launcher / fix files. [Moderate Success]
• Restarted my computer/game [Low Success]

When I would randomly lose connection:

• Rebooted / restarted internet. [Worked]
• Checked my ethernet cable and made sure it was securely plugged in. [Worked]
• Updated my NIVIDA Drivers.  [Moderate Success]

Anything else I missed would be in the thread.

Anyway, thank you to all that helped. I guess if this problem arises again or I have another question, I will be in contact with you all again.
