Asus RT-AX89X

[Riderek]

Hello, I'm new here with my router

The problem with the router is that the router disconnects from the WAN network very often, disconnects 2.4 and 5 GHz Radios, after some time it works normally and so on. Currently I am using software 3.0.0.4.386_23012 and it disconnects less often, but still too often - several times an hour. With the latest software, it happens even more often and the router would also reset, but in such a way that it could not turn on but kept resetting, only turning off the power and discharging the capacitors helped. I did a hard reset, a RAM reset and used firmware restoration to upload different versions of the software, it doesn't change anything, it just sometimes works longer or shorter. I was thinking about replacing the SPI chip with the software and uploading a new one via SVOD, or replacing the memory chip with new ones, e.g. from Samsung instead of Micron. If anyone could advise me, I would be very grateful. I will add that the temperatures of the systems on the motherboard are max 50 degrees CPU and 25-45 5 GHz system. Adds a log from the moment of disconnection, marked in red. Regards

Your WAN is switching speeds like the cable or port is damaged. Do you have another CAT5 cable you could test with?

yes 3 cables was testes

yes 3 cables was testes

Then there's probably something wrong with your cable modem or ONT. Check its log.

Ont was tested on two other routers and worked without problems. Now I was using Lan, wifi 2.4 and wifi 5ghz at the same time and my connection was disconnected for a few seconds every dozen or so minutes and the log looked like this

If anyone is curious, I solved the problem, although it was a bit nerve-wracking. All I had to do was reball SDRAM and NAND Flash Memory, the router worked like new. The reason is probably strong components, which cause them to get very hot, which leads to cold balls under the BGA.

Which hardware version is your router?

 

[Riderek]

I'm using the newest one, but I recommend the older ones like this "RT-AX89U_3.0.0.4_386_47027-g965d016_202201191513" in older software, in the system logs you can see the temperature of all working chips, it is refreshed every hour
