if you connect through etherent can you give this a try please :
it involves setting the network card to use 10 base half duplex, which is becoming a bit of an issue with the Samsung STB's
< ripped from Mr Walkers site as he explains it so much better than me lol >
Windows 2000 or XP: to change to half-duplex:
- Open Control Panel.
- Double-click Network Connections.
- Identify the icon for your cable modem connection: usually Local Area Connection.
- Right-click that icon and select Properties.
- Under the ethernet adapter icon, click the button Configure.
- Click the tab Advanced to bring it to the front:
- In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT.
- In the Value box, select a value which either (a) explicitly says half-duplex or semi-duplex, or (b) at least does not say full-duplex [e.g. 10BaseT on its own is OK]. If there is a choice between 10 and 100 with half-duplex, choose the 10. Do not choose 10Base5, 10Base2, or AUI.
- Click OK to exit the Adapter settings.
- Click OK to exit the Connection properties
see if this resolves any issues with the connection, you may need to reboot everything, STB & pc, for it to take affect, though shouldnt need to...
