The HHG2500 is a pretty appalling piece of kit! It has problems co-existing with access points if they are using the same SSID - if using auto channels the 2.4GHz WiFi will just shut down (5GHz seems unaffected)! Attempting to use the built-in Twonky media server causes it to overheat and reboot - you can test this using an LCD thermometer adhered to the plastic case just below the Vodafone logo, start Twonky, and watch the temps of the PLASTICS soar. It appears that the 24.GHz WiFi band is deliberately throttled (more overheating issues maybe - that's just a guess). If you have any devices on your network that use UPnP the router seems to interfere with the protocol, making streaming "unreliable". In fact any device to device contact (including printers) within the local network becomes unreliable. So it's pretty well completely unusable for anything other than basic web access or streaming directly from the web, even then if you have two local devices streaming from the same web server, it's NAT doesn't seem to work properly and the second source to connect usually just stutters and dies.
