Hi all. About 5 days ago I purchased a new TP-Link Archer BE550 Router and RE705X AX3000 Mesh Wi-Fi 6 Range Extender. I upgraded my router BE550 to the current firmware (V1_1.0.12 Build 20240902). I have 1GBit fiber in my house. My previous router was Asus ROG Rapture GT-AXE16000. I still have it at the moment. But I bought this router because I wanted to use TP-Link, but it was a disappointment for me. My internet speed is very unstable.

I constantly run speed tests on my iPhone 15 phone, Samsung S24 phone and Asus Rog G614 laptop. From time to time I get 800-850 mbps, but after a few hours it drops to 200-300 mbps. When I turn off the router and turn it on after a few minutes, it gets better again. There is such instability. Also, although I have activated remote management, I cannot connect.

I have read the relevant articles and could not find a solution. Also, I never encounter such a problem on my Asus ROG Rapture GT-AXE16000 router. Only my TP-Link router has this problem.

I'm also curious why my TP-Link router doesn't have a Speed Test application? I guess older models have this app, but none of the newer ones do. Will this be added with a firmware in the future?

I have seen a lot of people having these problems, will they be solved soon?
