I had 2 main problem with this router,

1-at advance wireless settings
channel_width 40mhz i save it, and its ok at that situation
but after reboot of router sometimes 2.4 is start at 20mhz when you login to web panel still you see it as 40mhz
but with wifi analyzer you can see it is working at 20mhz
after u need to save your wireless setting you see with wifi analyzer its 40mhz.
and this problem cause low mpbs.
2- i was using archer c7v2
upgrade my system to archer c3150v2
probably cause of smb1 supported by c3150 i couldnt see my files
but with archer c7v2 i had no problem.
This is very disappointing, more professional router with less support and smb1 is not secure.

waiting for firmware update
and i saw some people else have same problem too.

And i share all this problems proofs with TP-link Turkey Support,
They opened a case for this and then said no firmware update for this product,
When i share this problem with turkey team product was listed as a new,
Just after this started to listed as a end of life,
Is this the way of solving problems, this is a professional router with 3150 Mb/sn with very goody hardware.
C3150V2 listed in market at 2018 and Tplink turkey listed them with 3 years support.
In 2020 just because of no firmware support, not usable product.
Waiting for help from forum, thanks.
