@rajsh I have the same issue and tp link don't give a damn about their customers, im regretting paying 300$ for this pos. 

@Yahyoh we should file class action suit against Tp-Link. It's been more than six months, haven't received any response if they are planning to fix it and when.

@rajsh tp link doesnt care about customers. i bought the mesh system since one year and only got 1 update? this showes how much they care about their products 

lets not talk about the highly requsted features from customers like changing wifi channel,full web interface, more advanced options.

and the 5ghz that only can push only about 400mbps max while its advrtised as 1300mbps....as its  stuck on 80Mhz for 5Ghz,

good job tp link, this is the last product i will ever buy from you, and i will never suggest to any one to buy these POS products.

@rajsh They recently posted here the new M9+ V2 firmware will be released in a couple of weeks, unless something extraordinary occurs. I suggest to wait and see how that works, I am looking forward to it. My M9+ V2 set is working ok as it is, but I do miss the ability to access from a browser so I think it will be worth waiting for.

I just upgraded all three Deco's (version 1) to the latest firmware (1.4.0 Build 20200324 Rel 51287) released on 6/8/20.

Did not resolve the 500Mbps download limit when in AP mode.

Not sure if this will ever be resolved.  Or, if TP-Link even cares as they do not respond to anyone's inquiries.

turn off Parental Control and AntiVirus. With this you avoid any packet checked by decos and increase speed like AP mode. 

Other setting into your router, put main deco IP in DMZ to avoid full double nat.

 

@leogz Parental Control and AntiVirus does not work with AP mode...
