So i did a speed test to make sure it wasn't my computer, my ping is 10, download speed is 19.67, and upload speed is 10.64, but for some reason, 15 seconds within logging in to my bounty hunter the connection gets worse and worse until it logs me out.

You will probably get better luck posting this in new player help with a lot more detail.

 

What server do you have characters on, what general geographic area are you coming from, what OS and machine specs do you have, are there any error messages etc.

try delete the cache file from game folder>swtor\Diskcachearea*.

 

then open cmd and run ipconfig /flushdns and reboot your router

 

then go again

You gave very little useful info. What sort of a system are you running - laptop or desktop?

Is a Bounty Hunter your only character, or does this not happen with other characters?

If you only have the single character (BH) I'd suspect that your system is overheating, particularly if it's a laptop. Try turning down the graphics settings to produce less heat.
