Review on Certified Refurbished TP-Link Archer T6E AC1300 PCIe Wireless WiFi Adapter Card with Heatsink Technology for PC by Tony Pierce

I bought this a few months ago and it worked fine initially. I noticed that it had issues with 5G, sometimes it wouldn't "see" 5G around, sometimes it would connect but not get a good IP address from the router. (The reason for 2 stars instead of 1 is that 2.4G works well.) All my other devices worked fine with the 5G modem/router. Now it will only connect maybe half the time and when/when it connects it won't surf, can't ping the modem/router at all. Very disappointing. I received a refurbished model, so maybe that's my lesson. Regardless, I stay away from any product in the future, even a brand new one.
