I searched this forum to find similar issues to mine but nothing seems to fit. Briefly, I got a wireless media desktop – Microsoft 1000, installed the software, had everything connected as it should be but it didn’t work. The system has recognized that new hardware is installed. I double-checked everything again, made sure batteries are good, but no joy. I reconnected my wired keyboard, using another wireless mouse to look for answers, but I found nothing that fit. I called Dell assuming as it’s their product and I just got delivery this morning I’d get some service but after 20 minutes wait gave up and I decided to post this. Any thoughts or suggestions?
