Hi I have purchased new late 2013 iMac 3.2 GHz i5 8G Memory and 250 GB Flash Drive. However I am constantly having problem with internet connection issues. My iMac is wired to the modem. I had Time Warner cable first but I keep having up and down with connection service. So I switched to Verizon Fios, now I have same problems I got from Time Warner Cable. I got 75/35 on Verizon Fios, when I have problem with connection, I get 7 on download and 4 on upload compare to what I should have get which is 75/35. Is it normal? or is my computer defective? Also, when I click Macintosh HD and click my documents, it takes about 15-20 secs to load what's in my folder. Is that normal? Thanks.
