ANYBODY???

Please provide some information about the hard- and software used.

Box type:7020
GUI (enigma1/enigma2):enigma1
Firmware version:1

I am trying to move internal harddisk recorded TS files to the pc, but the network is very very very slow. Using a 7020 or a 5620 (using NGRAB) on the same configuration I have beautiful speeds no problem at all. I heard on varius forums that there is a hardware problem on some 7020s (1st generation like mine) and the problem is solved by soldering two new capacitors on the board. Please inform me for what to do since there are only 1-2 months to the guaranty end day.
Thank you
