[Bug 1017271] New: realtek drivers weak signal
http://bugzilla.suse.com/show_bug.cgi?id=1017271 Bug ID: 1017271 Summary: realtek drivers weak signal Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: diamantis.karagkiaouris.dev@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Dear all, I have an integrated realtek wifi card which seems to have very weak signal no matter what i have tried. It could connect to wireless network, but it doesn't have access to internet. My network card is specifically: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter Kernel: Linux linux-sjtp 4.8.14-1-default #1 SMP PREEMPT Mon Dec 12 07:58:11 UTC 2016 (ab53e9a) x86_64 x86_64 x86_64 GNU/Linux I figure out to find a workaround by following these steps: 1) Clone git repository with drivers: git clone https://github.com/lwfinger/rtlwifi_new.git 2) Build and install them all: sudo make install 3) Remove old module: sudo modprobe -r rtl8723be 4) Add the new one with the antenna option: sudo modprobe rtl8723be ant_sel=2 5) Keep the settings permanent: sudo echo options rtl8723be ant_sel=2 > /etc/modprobe.d/rtl8723be.conf Did anyone encounter something like this? Did anyone find a solution better than this? Thank you! -- You are receiving this mail because: You are on the CC list for the bug.

On some models, they included only a single antenna, and miscoded the EEPROM to indicate that that antenna was attached to the other connector. It has been encountered by many users as shown in the Issues associated with the referenced GitHub repo. The ant_sel module parameter was added to the driver in kernel 4.7 specifically to handle this one condition. The only other fix is to open the machine and move the antenna cable to the other connector; however, there are reports that doing this breaks the Windows driver. The GitHub repo was created to backport upstream changes like this so that users of earlier kernels would have access to new features. In this case, it seems to have worked as intended. In short, this work around was devised to correct a HARDWARE misconfiguration, and I am not aware of any better solution. In any case, it is not a software bug. -- You are receiving this mail because: You are on the CC list for the bug.
