Subject: [PATCH v2 0/4] rtlwifi: Fix issues with rtl8723ae
Date: Sat, 5 Jan 2019 18:38:49 +0000 [thread overview]
Message-ID: <DB7PR07MB53536F93922110AAB221480AE48F0@DB7PR07MB5353.eurprd07.prod.outlook.com> (raw)
Currently the rtl8723ae driver is broken (since v4.7).
Connection to AP is lost very often, especially when
the signal level is not very good.
The main issue is the power save mode is basically
not working, and seems to trigger a firmware bug.
So I had to take out the FW LPS mode handling.
While debugging the driver I found a couple related issues,
for instance that the signal level in dm.undec_sm_pwdb
is no longer accurate (may be even much too high) when no more
packets are received, and it increases the likelihood to receive
something if the input gain is set to maximum.
The patch was tested with the rtl8723ae PCI card in my laptop
against a FRITZ!Box 7590 AP -- the WiFi connection works now
very reliable for me.
V2 of the patch adjusts the defaults of swlps and fwlps module
parameters to match the firmware capabilities instead of removing
the whole code, so it can be easily re-activated once a firmware
update is available.

rtlwifi: rtl8723ae: Don't use dm.undec_sm_pwdb for input gain control
when no beacon was received in the connected state
rtlwifi: rtl8723ae: Re-introduce
rtl8723e_dm_refresh_rate_adaptive_mask
rtlwifi: Move the clearing of rtlpriv->link_info.num_rx_inperiod in
rtl_watchdog_wq_callback a few lines down
