[SOLVED] Extremely Slow WiFi
Posted: Wed Feb 15, 2017 10:18 pm
SOLUTION:
It works!
I disabled IPV6 and turned off Wi-Fi Power management. I also disabled 11n.

Speed up your wireless internet
9. For some wireless chipsets, a simple tweak is sufficient for increasing the speed and the connection quality of your wireless internet. Namely disabling the power management for the wireless chipset. The price you pay is obviously an increase in power consumption, although this increase isn't big.
You can do that as follows:
a. First find out if Ubuntu or Mint applies power management to your wireless chipset:
Launch a terminal window.
(You can launch a terminal window like this: *Click*)
Type in the terminal:Press Enter.Code: Select all
iwconfig
You can then not only see the name for your wireless chipset (for example: wlp2s0), but also whether Power Management is on for it. When it's off, or when no mention is made of Power Management at all, you don't need to do anything.
b. When Power Management is on, proceed as follows.
In order to prevent typo's, copy/paste this line into the terminal (it's one line!):
Press Enter.Code: Select all
gksudo xed /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Now a text file opens. In that text file, you see the following content:
[connection]
wifi.powersave = 3
Change 3 into 2.
Save the modified file and close it.
c. Reboot your computer.
d. Then check in the terminal, by the command iwconfig, whether Power Management for the wireless chipset is off now.
If so, you're done!
Speed up your Intel wireless chipset
10. If you have a (reasonably) modern wireless chipset from Intel, it'll run on the iwlwifi driver. If so, you'll probably be able to increase its speed noticeably, by turning on Tx AMPDU for it.
The purpose of AMPDU is to improve data transmission by aggregating or grouping together several sets of data. Thus it sharply reduces the amount of transmission overhead.
It used to be "on" by default in the iwlwifi driver. But several years ago, it was turned off because of stability issues on a few wifi chipsets. This problem category is, however, only a minority.
For turning it on, proceed like this:
a. First check whether your chipset runs on the iwlwifi driver:
Launch a terminal window.
(You can launch a terminal window like this: *Click*)
Use copy/paste to transfer this line into the terminal:Press Enter.Code: Select all
lsmod | grep iwlwifi
Does the terminal output contain the word iwlwifi (in red letters)? If so, proceed with the next step.
b. Use copy/paste to transfer the following blue line (it's one line!) to the terminal. Don't type it: it's too easy to make typing errors....
Press Enter and submit your password. Note that your password will remain entirely invisible, not even asterisks will show, which is normal.Code: Select all
echo "options iwlwifi 11n_disable=8" | sudo tee /etc/modprobe.d/iwlwifi11n.conf
c. Reboot your computer.
d. Finally, check your new wireless speed, for example on speedtest.net.
Has your wifi become unstable? Then undo the iwlwifi hack as described below (item 9.1).
Problems? Then undo it like this
10.1. Does the iwlwifi hack create stability issues for your wifi? Then undo it with the following terminal command:
Then reboot. All should be then, as it was before.Code: Select all
sudo rm -v /etc/modprobe.d/iwlwifi11n.conf

Hello,
I've just installed Linux Mint 18 Cinnamon, and the WiFi works but it's incredibly slow.
In looking at the Drivers in the System Settings, the only one available to use is for intel microcode, which is enabled.
Here's the output for my wifi-info (from the Ubuntu forums, I guess. I found it while searching these forums and reading several topics of people that had the same problems, but different hardware)
Thanks ya'll. I look forward to getting this fixed and using LM as my primary OS. (I've just replaced windows- irrevocably)Code: Select all
