I need help. I just installed Ubuntu 16.04 as dual boot along side windows 10. It connects to the network but the internet is extremely slow or doesn't work at all.

lspci -knn | grep Net -A3
04:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8812AE 802.11ac PCIe Wireless Network Adapter [10ec:8812] (rev 01)

    Kernel driver in use: rtl8821ae
    Kernel modules: rtl8821ae

Thank you so much in advance.

  • Please [edit] your question and add output of lspci -knn | grep Net -A3 terminal command. The troubleshooting is no machine-specific but it is (wireless) chipset-specific and we need to know which one you have in order to help you. –  Sep 09 '17 at 00:10
  • does any of that mean anything to you? – Mike Jay Sep 09 '17 at 00:45
  • Yes, it does. RTL8812AE is problematic: https://askubuntu.com/questions/942590/wifi-connection-keeps-dropping-on-16-04-realtek-rtl8812ae and https://askubuntu.com/questions/633473/15-04-32-bit-unstable-wifi are just examples, there are many more and no straightforward definitive answer. –  Sep 09 '17 at 14:20
  • so maybe just buy a new wireless card? – Mike Jay Sep 09 '17 at 15:19
  • alternatively , could i just choose a different distro of linux like debian and have it work with my current hardware or do drivers work for everything linux? sorry for my ignorance i am trying to get something working – Mike Jay Sep 09 '17 at 15:32
  • I would like to make a couple of remarks but before that I must make it clear that I'm no expert in wireless (I tend to choose hardware I already know works fine) do, the comment above comes from what I could gather by searching here using the chipset's name. That said, it's important to understand: 1. Drivers are at a kernel level; working differently in another distro is unlikely. 2. Maybe there's a good solution already but I couldn't find it. –  Sep 09 '17 at 16:08
  • thanks for your time at the least i appreciate it . I decided to scrap my dual boot all together and dust use a windows dev environment . I will eventually get around to buying a wireless card that works with ubuntu. – Mike Jay Sep 12 '17 at 01:24
