Issues with RTL8188EE Wireless Network Adapter

Hello everyone!

I have a Toshiba S55 A5295 with RTL8188EE Wireless Network Adapter Realtek Semiconductor Co. Years ago when I bought this laptop, I experienced issues with maximum download speeds of 70-90 kilobytes per second on much faster connections. I always thought that it was a hardware issue, so I used a USB adapter and everything worked fine. This issue was present the same on Arch Linux, Ubuntu and Windows.

Some time ago, the issue suddenly disappear on Windows and Ubuntu. I supposed it was related to some driver updates after Ubuntu 16.04 and Windows 8.1. The problem is that the issue is still present on Arch Linux. What I want to know is how can I know the specific driver information on Arch Linux to compare it to the Ubuntu driver info. What do you recommend?

This is the result of lspci -v:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)
        Subsystem: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter

Re: Issues with RTL8188EE Wireless Network Adapter

You have the driver from the lspci output

        Kernel driver in use: rtl8188ee

The version would be whatever kernel you running on the system.
The firmware you can check from modinfo rtl8188ee which is probably rtlwifi/rtl8188efw.bin meaning /usr/lib/firmware/rtlwifi/rtl8188efw.bin as supplied by whatever version of linux-firmware the system is using unless you overwrote that file.

Re: Issues with RTL8188EE Wireless Network Adapter

Thank you! I checked and it is strange because the Arch Linux version of the driver is newer than Ubuntu's.

Ubuntu:

vermagic:       4.15.0-20-generic SMP mod_unload

Arch Linux:

vermagic:       4.16.13-2-ARCH SMP preempt mod_unload modversions

And no, I didn't modify anything on /usr/lib/firmware/rtlwifi/

There must be something else.

Re: Issues with RTL8188EE Wireless Network Adapter

compare "systool -vm rtl8188ee" on arch and ubuntu. Usual suspects are powersaving and hw encryption (and the module has couple of parameters for those)
In doubt, use swenc and disable all power saving (aspm=0 ips=0 fwlps=0 swlps=0) and MSI (msi=0) for a test.
