The D-Premier supports only the 2.4GHz WiFi frequency range. The Expert Pro with CI module installed supports both 2.4 and 5GHz. The latter offers higher bandwidth and there’s more available channels so less risk for interference from neighboring WiFi. It’s also shorter range but this can often be an advantage interference wise. The 2.4GHz band is rather over crowded and is also susceptible to interference from other devices like baby monitors, faulty microwave ovens, Zigbee lighting, Bluetooth etc. etc.
-30dB is quite good. Back in the day when my Expert was still a D-Premier I had similar strength with a router nearby and even though I checked for the least crowded channel with InSSider (freeware tool back then) I did occasionally experience dropouts. There’s really not much you can do except for what you did, so place the WiFi router/accesspoint near to the Devialet and find a tool like InSSIDer which shows which Wifi networks are close to you and then find the channel with the least strong networks and change your Wifi router to that channel (channel 1, 6 or 11). Most routers do this automatically btw but it’s not always reliable especially since routers are continually adapting their transmitting power.
