For weeks I've been struggling with clients, mostly iDevices and IoT, keeping their WAN connectivity on my new RT-AX68U / AX2700. These devices do stay connected to Wi-Fi (no internet though), but I even had an Ethernet connected camera crap out too. For weeks, I've tweaked everything to death trying to figure out what's going on. I was using Merlin 386.4 Alpha (which I don't blame), but just installed the new Asus 188.8.131.52.386_56898 Beta - https://drive.google.com/drive/folders/1wvFKrOprbgDcrTk6yh84OOm8uZHsPgIZ?usp=sharing . This conversion was with webui and hard factory resets (plural). Upon setting up the AX68U again through its wizard, I opted to disable WiFi 6 (802.11ax) since I have a range of new and old crap connected. The only thing I've done extra is DoT and turned off universal / implicit beamforming. Things seem to be working better (less within the system log), but I need a full 24 hours to see if something goes awry with a client. The bonus using Asus' new beta firmware for the AX2700 is that it has WireGuard baked in. My debate is whether to return this $160 AX68U that seems to have a slightly better range than my old AC86U. I know of one other who has ditched their new AX router.
