The U Shower has buggy WiFi. It's 2.4Ghz-n, but very picky about the type of AP it's willing to connect. With my AC86U, it had no problems connecting. With AX86U Pro, it will not connect. I've replicated the settings between the AC and AX. Roaming assistant, airtime fairness, MIMO, OFDMA, explicit and universal beamforming are all disabled. Is there anything else I should look to try? Thanks.
