As far as I go away from it, even one meter, the signal drops to 50% and if I walk a few meters the signal is so weak that it drops the connection.\r\n\r\nAlmost all reports I could read from the net suffer similar symtomps, specially with heavy transfers ... packet lost, tcp segment retries and there are reports older than one year.\r\n\r\nThe laptop has dual boot so I can test the wireless card with windows 10 drivers and the signal is perfect, even several rooms away I get a decent speed, with linux exiting from the  room is granted to drop de connection.\r\n\r\nDisabling/enabling module's  parameters (fwlps, ips, msi)  either 4.4.0 or rtlwifi_new doesn't make any difference.\r\n\r\nany idea what could be happening here?\r\n\r\n<pre>\r\n# for f in /sys/module/rtl8723be/parameters/*; do echo -n \"$f: \" ; cat \"$f\" ; done\r\n/sys/module/rtl8723be/parameters/debug: 0\r\n/sys/module/rtl8723be/parameters/disable_watchdog: N\r\n/sys/module/rtl8723be/parameters/fwlps: N\r\n/sys/module/rtl8723be/parameters/ips: N\r\n/sys/module/rtl8723be/parameters/msi: N\r\n/sys/module/rtl8723be/parameters/swenc: N\r\n/sys/module/rtl8723be/parameters/swlps: N\r\n\r\n# iwconfig wlan-01\r\nwlan-01   IEEE 802.11bgn  ESSID:\"olimpo\"  \r\n          Mode:Managed  Frequency:2.437 GHz  Access Point: A0:A8:CD:A7:1B:4C   \r\n          Bit Rate=1 Mb/s   Tx-Power=20 dBm   \r\n          Retry short limit:7   RTS thr=2347 B   Fragment thr:off\r\n          Encryption key:off\r\n          Power Management:off\r\n          Link Quality=50/70  Signal level=-60 dBm  \r\n          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0\r\n          Tx excessive retries:0  Invalid misc:0   Missed beacon:0\r\n\r\n# lspci -s 2:0.0\r\n02:00.0 Network controller: Realtek Semiconductor Co., Ltd.
