Thanks afaq, but that had no effect.
Do I need to have Encryption mode: Prefer encryption
Use PEX to find more peers: tick/no tick
Use DHT to find more peers: tick/no tick
Use UPnP or NAT-PMP port forwarding from my router: tick/no tick
Pick a random port every time Transmision has started: tick/no tick
Enable web client: tick/no tick

Thanks.
