Re: Most reliable dual band driver/chipset rtl8812au Intel 8265 Fenvi




Posting as searchable, followup info.

I found a relatively cheap PCIe adapter labelled Fenvi FV-K1200ac that has an Intel 8265 chipset with ac1200 capability
and Bluetooth.  Loaded the iwlwifi drivers, plugged it in and rebooted to a perfectly working Intel wifi adapter. 
Not quite as fast as the Alfa (when working) but I think it's an antenna issue that I'll upgrade and try.  The router is about
50ft away but connection speeds are 500Mbs+ and often over 700Mbs, which is many times faster than my Internet
connection anyway.  But a reliable connection, at last.

Also updated my Stretch 9.6 from kernel 4.9 to stretch-updates v4.18.  Fenvi still works and now has the latest drivers.
Had an issue with a missing Nvidia driver but easily resolved with apt as all the files were there, just not installed.

Recompiled the rtl8812au driver for the new 4.18 kernel and the disconnection problem still exists.  It appears that something
in the params or driver is shutting down the adapter causing the disconnection and then needing either a LONG time
to recover or being physically disconnected (USB)-reconnected to regain the ability to make the wireless connection.

In regard to my issue below:

Trying to find an internal Intel based card with remote antenna.

I have Linksys USB wifi adapters and they work, but not dual band.  Not really
necessary, but why not use everything available.

Not a laptop and not a heat issue.  Something in the hardware or driver seems
to leave this adapter in some unstable state that requires a cold start,
either disconnecting the adapter from USB, rebooting the computer and sometimes
just unloading and reloading the driver.  Very irritating since it works very well when
connected, just unreliable.  Sometimes it'll stay connected for days, sometimes just
for a few minutes.

I've been using an Alfa dual band USB3 wifi adapter and while it works and when it happens to stay connected it's fast and fine. But it disconnects often for no apparent reason and won't reconnect by itself without removing and then reloading the module. Built and tried several versions of the rtl8812au and found one branch that I've been using, v5.9.xxx versions work but with the connection reliability issue.

Looking for a recommendation for an adapter and/or chip.

Thanks,
Tony
