hi
I got the precision 5520.
I have a problem with the wifi where I recognize as:
a. Can't work with google docs in Chrom browser. Google docs always stuck. and also the Gmail.
b. When I work with hotspot from my phone, I recognize that the amount of data transfer is abnormanl (I only worked with Emails).
c. In general, I compared with an other laptop that I have at home, and I really felt the difference in the rate of responses.
d. i updated the drivers, but it didn't help.
