Firmware Update for Realtek Wireless Adapter

Post by chiguy1256 » 2019/01/05 13:48:33

Are there firmware updates available for Realteck Wireless Adapter RTL8723BE PCIe Wireless Network Adapter? The reason why I ask is I installed CentOS on my laptop yesterday, but the wireless signal is weak. I have tried other distros and have not experienced this issue. I have attached a hardware report. Please advise. Thanks.

I have added the repository and ran yum -y update && yum -y upgrade. No packages to install. How can I find out if there is an updated driver for it in Linux? Thanks.

I have downloaded the driver from GIT. I get the error below when I run the make command. Please advise. Thanks.

Hi, Try this:

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh https://www.elrepo.org/elrepo-release-7 ... noarch.rpm

yum install kmod-rtl8723be

Bye

I tried to follow along a Youtube video. I cloned the github repository into /opt/rtlwifi_new. Everything seems to be there, but I get some errors when I try to execute make && make install. This is very frustrating. :(
