My son keeps telling me I should return my AX86u and get the TP-Link AX6000 because my RT-AC5300 died a few months after the warranty expired. He has an older TP-Link that he has never had a problem with it’s about 5-6 years. I have the AX86u set up in an Aimesh with an older AC68p which out lasted the AC5300 and it is working great so far. I’m over 70 years old and not quite sure what to do. I still have a couple of days to return my AX86u just looking for some other opinions.
