My AC1750 Ver: 5.8 is also experiencing a dropping connection. But I do not see a reference to a relevant patch on this forum. Would you be able to assist?
@Loudfreeze Can I have the model number of the AX1750? Is it Archer C7 or A7? What is the current firmware version on it? Who is your ISP?

@Kevin_Z it's AC1750, model A7(US), version 1.1.4. ISP is optimum.

@Kevin_Z Happy to report after several intentional reboots and a scheduled reboot - the router is very stable. Frontier FIOS.

@Kevin_Z Thank you for this firmware! I have an Archer AX21 v1.20 that's been requiring multiple reboots daily for several weeks now (since before the new year), and this beta firmware seems to have fixed it. This is on google fiber Webpass, San Diego area.

@Tu2thepoo I'm glad to hear that the beta firmware helps resolve the issue you were experiencing. Please wait and check for the new official firmware on the router web GUI or via the Tether app, which will be released soon.

Just wanted to throw my voice in with the rest as I was having the same issue on the AX21 v1.26. After the latest firmware update my internet started dropping every 30 - 60 min. Rolling back to previous firmware seems to have resolved the issue. Going to give it one more day to ensure it's not something else and then test out the beta firmware tomorrow. I will update here with results.

I recently received an RMA replacement of an AX1800 V1.26 that had the dropped Internet problem. The connection between the modem and the router would drop and a green light on the router would change to amber. The RMA replacement also had the same problem. By chance I saw this thread today and flashed the firmware of the RMA replacement to the posted beta version. It's been half a day and and the connection has been working steadily. Weird how none of the TP-Link tech support agents I've dealt with were aware of the beta firmware fix.
