Hi. Today I just received my Acer Aspire E 15 E5-575G-57D4 laptop from Amazon, and did a clean install of Windows 10 to get rid of all bloatware. After the clean install, my wifi speed only goes up around 2 Mb or so. Please let me know how to fix this. Thank you!

    I am having a similar problem.  Bought an Acer Aspire E 15 E5-575G-57D4 off of Amazon.  After initial set up of laptop, when I try to connect on laptop via home WIFI the signal drops to a crawl. 
    I use speed test on my phone, and when laptop is on and connected, speedtest shows much higher ping (120ish from 40) and lower download speed (.02mbps down from 6mbps).  Upon disconnecting laptop wifi or turning it off, wifi will return to normal stats. 
    This was a christmas gift to my wife, and she is most disappointed in its inability to use wifi.  Please help.  Thank you!

    This might help:
    Click on Device Manager
    Click on Network Adapters
    Click on Qualcomm Atheros QCA9377 Wireless Network Adapter
    Click on on Advanced
    Click on on Wireless Mode
    There are 12 possible settings. I set the value to 02 - 11 g
    Choose OK

    I tested all 12 possible settings:
    01 11b 6Mbs up/6 Mbs down
    02 - 11 g 20/18
    03 - 11 b/g 20/17
    04 - 11 g/n 6/43
    05 - 11 b/g/n 5/43
    06 - 11 a  nothing
    07 - 11 a/n nothing
    08 - 11 a/b/g/n/ 5/42
    09 - 11 a/g/n 7/43
    10 - 11 a/n/ac nothing
    11 - 11 a/g/n/ac 7/45
    12 - 11 a/b/g/n/ac 6/43

    Over Ethernet, I get about 75/75.

    Salvation!  

    But it is amazing that the wireless card has such issues.  I have 50/50 at home and my cell phone gets has higher up and down speeds.
