@SanDiegoEngine amazing fix - thanks - used tools within the app - switched and speeds went from 3mbps to 14

I purchased the RE580D range extender a couple weeks ago to extend my 5Ghz network (the wifi router is a TP Link Archer C7).

After installing the extender I had great connection speeds, but unfortunately after a day or so of connectivity, the Internet connection would completely drop between certain devices and the extender. Rebooting the extender was the only way to fix the problem, which was not ideal.

I read some other posts on this forum with similar issues, and I think I have found a solution that I wanted to share with this forum.

In short, follow the instructions outlined in this support document: http://www.tp-link.com/us/faq-943.html
so that your connectivity goes FROM this (bad): wifi_router <=== 2Ghz & 5Ghz ==> wifi_extender (extends network on 5Ghz)
TO this (good): wifi_router <=== 2Ghz ====> wifi_extender (extends network on 5Ghz)

My wifi extender speeds stayed the same (to my surprise) even just at 2Ghz, and the wifi extender is much more robust now for both wired and wireless clients.

My guess is that there is a bug in the extender so that 5Ghz connectivity to the wifi router get into a funky state, and the extender cannot recover without a reboot.

Hope this helps someone else!

....now no longer drops daily...

@MB100 I'm trying to reply to  community threads to spread the word about how I fixed my extender issue.  I think there's a general problem in some TP-Link devices, it runs out of resources (i.e. CPU) and cause those network drops.  The solution I found was to change the Wifi-Coverage range setting from Maximum to Minimum, that way the device isn't running at maximum CPU, and has enough CPU resources to manage all devices and their traffic. 

Farouk-Ontario's post was the final one that fixed it for me. Mine's an RE450 but I had exactly the same issues described here. Reduced coverage from Max to Min and got back some much needed stability. I had already disabled one of the bands - after over 5 extenders I still haven't come across one that can manage two bands reliably with a lot of wireless and wired devices attached.
Still need to throttle downloads to about 50Mb/s which is a bit frustrating as the marketing material claims 1300Mbps, but can't complain too much it's twice what I was getting not long ago.
Can't help but wonder if the QA dept didn't test it literally as in 1300Mbps works ... for one second! ;-)

@SanDiegoEngine greatly appeciate your post. I bought a RE220 and was experiencing an issue where after 2 or 3 days I would loose my connection. Someone on another forum link to your post claiming this would solve the problem. Indeed it has. Thank you.
