What worked for me was enabling the MSI parameter (message signal
interupt). I have a lenovo Z50 laptop. My wifi would work with all wifi
laptop manufacturers but i was having a problem with a Lancorm wifi
router at a Hotel I once stayed.
what i did was this. I scrowled to the file "sw.c" in the folder
"/home/peter/rtlwifi_new/rtl8723be"
Then in the sw.c file, I added the variable ".msi_support" (which was
missing) and initiated it to "false" under the data type "rtl_mod_params
rtl8723be_mod_params" i.e
static struct rtl_mod_params rtl8723be_mod_params = {
.sw_crypto = false,
.inactiveps = true,
.swctrl_lps = false,
.fwctrl_lps = true,
.msi_support = false,
};
Since msi_support is by default disabled, we have to appropriately
initialize it as disabled(hence false),
I then complied the code, ie
cd rtl8723be
make clean
sudo make install
sudo modprobe rtl8723be
after that I set the msi parameter to 1, in the file "rtl8723be.conf" which can
be found under
"/etc/modprobe.d"
i.e
options rtl8723be fwlps=N ips=N swenc=Y msi=1
You may have to reboot the computer and wait after for a couple of
minutes after restarting the browser for the msi to be triggered.
This worked for a lenovo z50. Depending on your pc, you may toggle and
choose instead an msi of 0
