Even after correcting him several times that I have had only 2 units the 1st and one replacement, at the end of the call he was still perplexed that I was having issues on my 3rd unit. He also kept saying things like I was the only person having issues with their product, still not owning the issue. Being at work, he said he was going to shoot an email to me with the details regarding his top tech guy who would be calling me either tonight or tomorrow. I sat at home all day Saturday waiting and never received the call. It turns out the guy was off those 2 days. Seems like an easy thing to check and an unacceptable error when you are trying to fix an upset customer's issue. I finally get a call from the top guy and we run through pretty much the same info and same troubleshooting again. Side note, anytime I reset the device it would kind of work for about 24 hours before issues returned, so it made it hard to immediately let him know if anything changed right then. SOLUTIONHe suggested that I get a Netgear router because he's noticed a lot of issues with TP Links, mine was only 3 months old and had the latest I know this is about to change AC standard. But I did. I got the Netgear AC1750.
