My AC 750 3110 WiFi Range Extender does not extend the range of my my WIFi...

Can someone for the love of God help me with my range extender. I bought an AC750 last week because my wifi in the bedroom I game in gets about 20mbps on a good day from 150mbps internet speed I pay for. The bedroom is no more than 60 feet from the router, tops, with one wall in between. I have set up the wifi range extender all over the house and tested it in various spots and the best I have been able to get out of it is 68 on the 5Ghz band. All the lights are green, the signal is strong theres nothing else in the house currently using bandwidth to speak of. Thats problem number one.

 

The second problem is that half the time it needs to "authenticate". I have to log in to the setup website and set everything up all over each time it does this. Why is this so difficult to get the fast internet from one room, to right around the corner with this thing? Can someone tell me A) if theres anyway to make this thing not suck and extend my signal with speeds up to at least 100 of the 150 that I pay for and B) why does it keep asking me to authenticate every couple of days?

    Can someone tell me

    A) if theres anyway to make this thing not suck and extend my signal with speeds up to at least 100 of the 150 that I pay for ---I think there's a misunderstanding in how extenders work. Extenders have to send/receive between the router and the extender. And then send/receive between the extender and device. And they can't do both at once. What this means is a standard extender (single or dual band) is going to take a 50% speed reduction of whatever speed its getting. So if you have 150mbps service you'll take a little reduction in speed because of distance from the router/interference. so say 130-140mbps.  Then you take the 50% throughput hit. That puts the speed at 65-70mbps. And that's for 5ghz. 2.4ghz is much much worse because its a much slower band. 

    If you want to try to get full 150mbps, then you need to upgrade to a system like a triband extender or triband mesh system. They're able to preserve speeds better because they have a dedicated 5ghz chip just for router---extender communication. 

    B) why does it keep asking me to authenticate every couple of days?----did you set it up using wps? if so, factory reset the extender and install it using the installation assistant. WPS can get coded different between device manufacturer's and cause issues.
