I bought a new Inspiron AIO desktop but it arrived with the WiFi dongle broken. I contacted the seller and he arranged for a new dongle to be sent from Dell.
The dongle arrived but I still could connect my keyboard and mouse.
I then contacted Dell customer service and was told that it will never connect because the three items are synced and cannot be replaced.
This seems ridiculous to me and I wondered if this is correct. I have now bought a new set.
