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.
