First off factory reset the router. Second, use a network cable to connect the router with your computer (use the first LAN port on the router to the LAN port on your computer). By default, after a reset the IP address will be 192.168.1.1

From there you can start configuring the router and change the IP address to a fixed IP (static IP). I chose 192.168.1.2, but if this one is already taken in your network. It might be a good idea to start in a new subrange (for example: 192.168.2.1 - 192.168.2.2 - ....)

I hope this helps.

I also have the same problem as him but l have only one which it is operated as a router. I have updated the version to its latest version and rebooted it but still the same problem. The number of connected devices was still the same since it was bought. I don't know what the model is but the box says ax3000 but the tether app says archer ax50.

@Wicklo 

Hello, your problem is not the same as BanditsAtZero’s. Please help verify some details:

May I know who is your ISP? Have you checked if the internet connection is stable when you plug your computer directly to the modem?

How about the internet LED on the AX50/AX3000 when the internet drops, is it orange or green? Can you access its web interface at that time? If yes, what are the WAN IP address and default gateway?

Besides, please follow the instruction below to do some tests and tell me which case you belong to:

I have the same problem but I have only one in which I used it as a router. I have updated the version to its latest one, rebooted it, disconnect the wan and plug it back in but still the same problem. The model that is written in the box is ax3000 but on the tether app is ax50. The devices that connected to the router are at most 13 buts usually 9. It was fine and all since I bought it but it has but turning orange yesterday and I don't know what else I can do. Is there any things I could try?

@Kevin_Z 

My ISP is PLDT and my internet connection is stable when I connect it to the modem/router that is provided by PLDT.

When the internet connection drops, the internet led of the router is orange but all the other leds are all green. I didn't try to connect to the web interface yet but I will try if the problem comes back. 

From the link that you gave, my problem is case 2 but I still haven't tried the steps because it says that I have to try it if there is no internet connection.

@Kevin_Z 

It just happened again so I tested the steps I need to follow.

The WAN IP adress is 192.168.1.3

The default gateway is 192.168.1.1

@Wicklo, @Kevin_Z 

I have the same problem, my ISP is also pldt. 

I have tried hard reset and disabling some features like anti-virus etc. but with no luck. For now, when it happens every couple of hours, i just unplug and reconnect the lan cable from the modem to ax50 😭. 

@Kevin_Z 

Is there any thing I can do to fix this? The router's internet led is frequently turning orange like every 20 mins.

@Wicklo 

Hi, thanks very much for all the details you've provided.

Please try to change the WAN DNS server on the AX3000 to 8.8.8.8 and 8.8.4.4, then reboot both your ISP' modem router and the AX3000, then monitor again.

@mac13 

Hello, is your problem exactly the same as Wicklo’s? Does PLDT give you a modem router and how about the WAN IP address on the AX3000 when the internet stops working on it?

Besides, please follow the instruction below to do some tests and try the suggestions if your case belongs to Case 2:
