You can open a port for LW: Port 6346 This will allow LW requests & uplding from you. Whether it directly affects your dwnlds I'm not sure. But having people uplding from you will improve your search & dwnld results.
1. I don't have instructions specifically for your model but see if this works for you:
Port Forwarding instructions for the ZyXEL Prestige 623 But you will need to set up a static ip 1st! Link to instructions are provided there.
2. Make a note of all your LW option settings then, delete the LW Preferences folder called
.limewire (whilst LW is closed!) & found here:
C:/Documents And Settings/your_username/.limewire
3. Also force ip within LW:
Force IP instructions & sample image
4. Update your Java:
Java 1.5 (take the JRE) Some xtra hints: A well set-up LW can start to automatically continue its dwnlding after it's settled down perhaps 2 out of 3 times you open LW. Optimising LW & Maximising Uplds & Dwnlds A (1st post only) & also Part B which is even better & last & least are search & dwnld hints. The latter one I've been thinking about re-writing for some time. That's just for playing it safe. eg- I show all speeds & qualities.
