Raspberry pi 8192cu driver driver#
Mac80211 650547 3 rtl_usb,rtlwifi,rtl8192cuĪpparently, before this upgrade the 8192cu driver was being used. This is for device with USB ID 7392:7811 - there may be other hardware revisions that will. Having hit version 1.0 in November 2020, and 1. So we need to blacklist one of these modules to make this wifi adapter work.
Raspberry pi 8192cu driver drivers#
We are shipping both drivers in our OS and this has the effect of the Realtek Adapter 8192cu to not work at all. Kernel module for this chipset is actually included in Debian 6 image (19-04-2012) distributed via Raspberry Pi website, but it will not work with the card. In a blog post by Raspberry Pi CEO Eben Upton - that the popular single-board computer is now conformant with version 1.2 of the Vulkan graphics API. Currently the raspberry pi kernel builds both the out of tree 8192cu kernel module and the in-tree rtl8192cu kernel module. Since the mainline driver doesnt work very well, the raspberry pi folks decided to include the same driver that is used in this repository instead of the mainline kernel driver in the raspberry pi kernel. Rtlwifi 85339 3 rtl_usb,rtl8192c_common,rtl8192cu Under the hood, EW-7811Un runs Realtek's rtl8192cu chipset. I believe the comment on the arch linux wiki was referring to the mainline kernel driver. They two can both boot normaly, and the main functions work OK. I use the Edimax EW-7811u USB stick since this Raspberry Pi is one of the original model Bs without Wi-Fi.Īfter debugging a bit and searching the Internet it appeared that I was now using the wrong driver, rtl8192cu instead of 8192cu: (henry:22:18:PDT)% uname -a > Updated kernel to 3.4.90 > This images can be used both on Banana Pi and Raspberry Pi boards. It installed Linux 4.9.28+ and I instantly realized there was something wrong since the Wi-Fi was very latent and would periodically disconnect from any nearby WAPs. Note no spaces before blacklist rtl8192cu. Add the line blacklist rtl8192cu to file /etc/modprobe.d/nf. I did a kernel upgrade on one of my Raspberry Pis earlier today by installing the latest raspberrypi-kernel from testing (1.20170515-1). I was about to add 8192cu to the driver blacklist, but suddenly I found the nf file. To get the 8192cu driver to load in 3.18.1 731 it's necessary to blacklist the rtl8192cu driver that is currently compiled in the 3.18.1 image.
