After switching to linux, I switched to a TL-WN725N wireless adapter and installed the rtl8188eu drivers. On windows I typically had anywhere from 2-15mb/s download speed and I am now getting around 100-300kb/s, what should I do?

The output to:

nmcli device wifi list | cut --characters=-8,26-

would give us more information about the channels in use and the speed at which they can operate so we can give you a more informed answer… (The BSSID which uniquely identifies you will be cut from the output)

You’re connected twice to the same SSID. Please change your router settings to have different bands use different SSIDs and connect to one only.

Would you care to share the output (screenshot, look here how to do that) of https://speedtest.net now then?

Sure, here is the screenshot

Fabby · 18 July 2021 15:04

That’s not good!

How exactly did you do that?

Have you tried kernel 5.13 before installing drivers?

leg · 18 July 2021 15:31

I used the tutorial described here and referred to this post:
http://brilliantlyeasy.com/ubuntu-linux-tl-wn725n-tp-link-version-2-wifi-driver-install/
https://forum.manjaro.org/t/trying-to-install-drivers-for-tp-link-tl-wn725n/64287/2

I have not, I am unsure of how to do that. I attempted to install the driver a few times using this method and others, but I have not seen any improvements and I dont think its working properly

Print this page so you have it as a reference while in TTY2
Log off
Switch to TTY2 by pressing Ctrl+Alt+F2
Log in there
Execute:
```
sudo mhwd-kernel --install linux513
```
to ensure grub is showing, execute:
```
sudo nano --backup /etc/default/grub
```
Change (or add?) the following 3 lines:
```
GRUB_TIMEOUT=3
#GRUB_HIDDEN_TIMEOUT=0
#GRUB_TIMEOUT_STYLE=hidden
```
(3 or higher is fine, add the # before the lines above if those lines are present)
Ctrl+X Y Enter to save if there is anything to save
If you did save, execute:
```
sudo update-grub
```
Reboot
Go to grub’s Advanced options
Choose the 5.13 kernels and see if that helps.

If that does not help,

Undo the changes you’ve done first.
Activate the AUR
install the 8188eu-dkms driver
```
pamac install 8188eu-dkms
```
Reboot and see if that helps.

If that does not help, uninstall the 8188eu-dkms and try the 8188eu-dkms-git one next using the same methodology as above.

Note: For the future, don’t use instructions for Ubuntu, Gentoo, … Linux on Manjaro but use Manjaro instructions that have a Solved status or Arch instructions.
