Can't connect to a server.

[Legend1023]

When I try to play tekkit classic with my friends. One of those friends hosts the server and everyone else is fine, but when I join I get a 30 second limit on the server and then I crash with a message that says "internal exception: java.net.sockettimeoutexception: read time out" I have read many posts on this problems and I have done many things to try fix it

Such as:

• Update Drivers
  
• Update windows
  
• Re-install Tekkit, hamachi and java
  
• virus scan (no virus's detected)
  
• (also running direct to router (not wireless)
  
• Process more RAM to tekkit (java)
  
• set priority to high
  
• transfered tekkit on the real Minecraft.exe
  

and still none of these work, At first the server was fine with 1-2 second delay and it was playable but about a couple of days ago I have just kept getting this message.

Could anyone please help me fix this.

Thank you
