[Bug 1320070] Re: Realtek Wifi card RTL8723BE drops connection with MSI enabled

 

My WiFi drop issues started again after kernel update:
Linux metodiew 3.17.0-031700rc4-generic #201409071935 SMP Sun Sep 7 23:36:45 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I tried solution from #48, but I got this error:
metodiew@metodiew:~/Software$ cd rtlwifi_new/
metodiew@metodiew:~/Software/rtlwifi_new$ make
make -C /lib/modules/3.17.0-031700rc4-generic/build M=/home/metodiew/Software/rtlwifi_new modules
make: *** /lib/modules/3.17.0-031700rc4-generic/build: No such file or directory.  Stop.
make: *** [all] Error 2

Is there something I'm doing not right or there is some issues with
kernel 3.17?
