This post is a bit longer, but I wanted to explain it in a way that most users will (hopefully) understand.
If you have connection problems with the server, check where the delay in server responses is accumulating. Do this by tracing the packet transfer times using the following steps...
1. Click on Start
2. Click on Run, or in Vista/Win 7 just skip to Step 3
3. Type cmd into the Open or Search box and press Enter
4. In the command prompt window that opens type "tracert patchserver.crypticstudios.com"
If cmd in step 3 doesn't bring up a command prompt, try cmd.exe. For step 4 then, type in "tracert.exe patchserver.crypticstudios.com"
You should get something like this:
Trace to patchserver.crypticstudios.com [18.104.22.168]
with 30 redirections at max:

End of trace.
That's a list of routers and servers your communication must go through before it reaches Cryptic server. Your router is on the first line, STO server is on the bottom. My connection is going through 15 different routers and servers before it get's to STO server finally.
Time on each line says how long it actually takes to data to get from your PC to current server/router in the path.
There are 3 tests for each server in the path, so 3 times on each line. Asterisk means the data didn't arrive to the server at all.
As you can see from the last line (the STO server), it takes 1.1s for my packets to actually reach the server. That is a long time. The game is then lagging and connection may be unstable if the time gets even larger (when STO server doesn't hear about you for several seconds, then he assumes you as disconnected and you then end in the login screen).
You can however see from the list that many servers in the path BEFORE the STO server were actually receiving the packet alread with a huge delay. So the problem is not on the Cryptic side. The delay appeared somewhere on the route and Cryptic can't do anything about that.
Where the problem is? The first line is my router and it says that data from my PC reaches my router in 1 millisecond. That's fine. But right on the second line the time suddenly raised to 600 ms. The second line is connection from my PC to a server that is right behind my router (server my router connects to for internet). And here is the problem. While my PC sends data to router fast (1ms), my router is sloooooow in resending the data to next server in the path (more than half second). How to deal with it? RESTART THE ROUTER! Power the router off for 10 seconds and then power it on. Wait for it to connect and then run the trace again. And voila, the problem with router disappeared, it's sending packets now much faster and so they can reach STO server earlier

Instead of 1.1s it takes now only 0.1s
Lags and disconnections are gone. Game is stable and I can play without ending in login screen everytime I warp to some system
One thing I noticed is that my router needs restart every few days when I play STO. I don't know why - whether the STO is sending so much data that the router logs get filled so fast or what. But if you're having problems with connection, it may be a good idea to check trace every even day and restart the router when you see the numbers are getting large
Well, that was when the large number jumps up at the beginning of the list (as shown above).
But what if the times are small for several first lines and gets rising around the middle? Then it's problem in the provider's network and only thing you can do about that is to contact your internet provider and send him the trace.
If the large numbers begin appearing only to the end of the list, then the problem is likely in Cryptic network and you should send message to Cryptic/PWE with your trace.
I hope that helps at least to some of you.
