A quick recap on a Dell Inspiron I bought in December 2014. So far I have had a video problem that was caused by the Dell Tech installing a bad driver while trying to fix a bad USB 3 port problem. I had to send the unit back to Dell in September 2015 when the display died, and again in February 2016 for the same reason. Every time I called Dell Canada I was routed to Dell US where I was told they couldn't help me because I was in Canada.
For the last two weeks I have been having a wireless problem. Two laptops side by side running the same monitoring software. One shows my signal strength at -27 dBm (5 bars) and the new Dell at -69 dBm (1-2 bars). Both are within 10 feet of my router (line of sight).
So I called Dell yet again. After an hour with the hardware tech during which he ran the PC-Doctor diagnostics I was told it was a software problem even though I told them that I had restored an image from two months ago (long before the problem). He transferred me to software support where they had me boot into the diagnostic partition and run the full slate (which didn't include a network diagnostic). They concluded that it was a software problem and that I would have to pay to get it resolved. I got the tech to agree that if I restored the factory image and still had the problem he would concede it was a hardware problem.
I hung up and restored the image.
Same problem (what a surprise).
Back to the hardware tech (a different one) where he had me run the PC-Doctor diagnostics again. Finally he agreed it was hardware. They are going to courier the part and have a technician come by and replace it.
Never buy Dell.
