One connection bar means you're not connected.

The port forward configuration for the BT voyager 220v doesn't show any UPnP option in the images it shows, but perhaps it's simply left out of the images. The ISP BT in UK has been known to cause problems for a few people. It appears BT might have started shaping bandwidth for p2p users during peak hours. They might also be blocking certain port ranges for p2p program use.

A recent case, they port forwarded their modem/router using a port between 49152 - 65535 & it solved their firewall issue. They were using a BT Hub however.

'If' you wish to try this option, the first thing to do is set up a Static ip address: Choose your operating system to Set up a Static ip. This is the most important step actually.

2nd & 3rd steps are listed here: Port Forwarding for the BT Voyager 220V except (a) choose a port between 49152 - 65535 instead of 6345, & in LW's Advanced > Firewall setting, make both listening & connection port the same as you port forward for the voyager, (b) Port forward either with combined TCP & UCP, else one for each. LW does need both.

At least until you connect: In LW's Tools > Options > Advanced > Performance, disable all those options.

Not sure about the Voyager, but for 'some' devices, you need to reboot the device to get such changes into operation. A reboot of computer might not hurt either, as this will help to clear the system of any possible 'old' loaded settings. (This is not necessary, but 'does' make a difference on 'some' systems.)
