I am facing this issue recently instantly with my D-Link DWA-131 wireless adapter. Mine is Ubuntu 16.04 LTS. My adapter was working perfectly since past 3 years. All of a sudden since 2 days, I am facing the issue of slow internet. With the adapter, speed becomes less than 10MB/s. Without the adapter, It shows 80-90MB/s.

I am suspecting some issue is with the D-Link adapter / the driver. Also I cant rely on my inbuilt adapter as it doesn't work always & cant afford to replace motherboard.

Every time I reboot my laptop, I get this exception. Is this somehow causing any issue !!
Exception:
[0.056088] ipmi:dmi : Invalid offset : 0

kindly please help....

You can try a module built from source code on github 

sudo apt-get install git build-essential dkms
git clone https://github.com/Mange/rtl8192eu-linux-driver.git
sudo dkms add rtl8192eu-linux-driver
sudo dkms install rtl8192eu/1.0
echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

Reboot
