loz did you try the fixes above? Fixes for LW & deleting your LW Preferences folder? Try it!
RevRocket: That test result is extremely poor news!!! It means that port 6346 is totally blocked! We can only hope that forwarding a port (opening port 6346) will fix this.
1. 1st you will need to set up a static ip. See instructions on 1st line of next page link:
Port Forwarding Guides for the Westell 2200 Wirespeed B90
2. When you get to the port forwarding stage, use
Port 6346
3. You have a choice of setting your force ip to auto or manual in the new version of LW.
Force IP instructions & sample image But you said you've already done this.
Note: When doing port forwarding, you MUST have a static ip. This is crucial otherwise it won't work. Next time you log on your different ip will mean your port will be ignored if you have a dynamic ip. If mistakes are made most people make mistakes setting up the static ip so read the instructions very carefully! Good luck.
