Solid built. Does what it's supposed to do well. Not sure about gaming over this haven't tried. My speeds are 100mbps download over WiFi router 5g band versus 30meg download over EX6150 150 5g band. Sleeps are only slightly slower over 2g bands. Quite impressed with it as got it on offer for 34.99. It's 54.99 but I think it probably is still worth it. Oh and also was also quite easy to set up but WPS wouldn't work so I used the browser.
Previously I was using a two unit Netgear range expander which expired after five years of dedicated service. This did performed the same functions but with just the one box.
Better value also as it was appx £20 cheaper.
It made no difference to the speed or signal. If anything when your connected to it you wifi runs slower than off the normal modem. Waste of money and over priced it just sits in my draw now.
