I have installed the hardware successfully linked to my sky broadband router and trurned off the WiFi in the sky router

i found the shy hd box mini WiFi adapter would not connect to the home net so bought an Ethernet cable and connected the deco unit to the sky box directly . Initially I thought it was perfect but now I find when trying to download on catchup the network if failing every few minutes . I reset it and it fails again and again . 
 

i might have to re enable sky WiFi and connect using the mini adaptor thus ignoring the deco home net 

anyone else come across this issue ?
