Well I hope it's not your isp that's causing the problem. A no. of european internet service providers (isp) are now filtering/blocking p2p programs. They use special p2p program detectors.

Let's try a couple of other tests. You'll need to have LW open at the same time as you do these tests.
1. Do this simple test for us. Using your browser go here: http://www.grc.com/port_6346.htm (Press Probe this port button) Does it say open or closed?
2. http://koti.mbnet.fi/gfactory/ctest/
3. http://jlh.no-ip.org/connectiontest/

I have a suspicion you may get an error with either tcp or udp. That's not necessarily a problem but might be as these specific tests can be affected by firewalls & NAT. My thoughts are that the incoming might be blocked. (Reasons for keeping LW open whilst you do these tests are (a) Linksys opens the particular port for LW via UPnP, (b) Something about these tests that needs the program to be trying to access the particular port before the test works properly. duh

Try connecting with UP turned off. Go to LW's menu bar, Tools>Options>Speed & tick disable Ultrapeer capabilities & press apply.

My 1st thought is, try another port (even though 6346 is open, this port might be filtered by your isp for p2p.) You may need to adjust your port settings in your firewall. For LW, go to LW's menu bar, Tools>Options>Advanced>Firewalls & change the listening port to one of the following. You may or may not need to relaunch LW for it to take effect I'm not sure. 80, 64049, 1111, 3500, 4008, 1203, 10000, 15189, 20282, 22817, 443, 34599, 40475.
