Bests & Worsts Reviews from Amazon

I bought this extender and installed it and everything was breeze so far. When i tested the download and upload speeds ( with extender pretty much next to the router), the speeds were half of the main WiFi. I called the support and we tried few things such as resetting the extender, ensuring the firmware is up to date etc and eventually the support person asked me to send screenshot of the speed differences between main router and extender to send to their engineering team. After couple of days, i heard from them for a troubleshooting session and when i send few timeslots. The next dayi heard that the half the speed from extender is expected since it is half duplex extender and whether i still wanted a troubleshooting session. I was not expecting increase in speed, but i was disappointed that their product description did not say anything about half duplex and reduction in download/upload speed by half. Hopefully, TP Link is more transparent about reduction in speed. I am returning it shortly.
