Help Needed (please) with a VERY simple script

[tipster69]

Hi,

I have my DM800HD set up for use when on the road (Motorhome) using a Netgear MBR624GU Mobile Router and a Huawei E220 Modem.

It works fine for x amount of time and then it starts to jitter, we seem to have got to the root of the problem in that the Modem drops from HSDPA mode into UMTS because of lack of data (i.e I update the EPG then the jittering stops because the modem goes back to HSDPA Mode).

I have read of a similar problem that was fixed by writing a very simple script to PING an IP address every x amount of seconds (I think it was every 2 seconds) and this worked.

My problem is I have no idea how to write or use a script on a DM800. Could someone PLEASE help me by advising in laymans terms how I do it.

THANKS IN ADVANCE
