AX11000 (V1) slow wifi
I have an AX11000 V1 router and a 600/60 mbps fiber optic connection. The device from the fiber optic (Dasan H665) is connected to the router with a Cat 7 cable.
For over two years, everything worked correctly, and I had full speed of the connection over WiFi (590-600mbps).
However, for the past few days, there has been a problem - I can only achieve 300-400mbps via WiFi. Suddenly, the speed dropped - I haven't made any changes recently.
It's not a problem with the provider, because everything is fine when using a cable (connecting a computer to the router with a cable) I get full connection speed.
The router was running on firmware 1.3.4 Build 20230906 rel.74809, but after downgrading and installing 1.3.3 Build 20230719 rel.78410(4555) the problem still exists. I looked on forums and found a few potential solutions:
- turning off QoS (or manually entering connection parameters there)
- disabling antivirus
But none of these options brought a solution for me. I reset the router to factory settings, but the problem still exists. The problem occurs on all devices I have at home. I've attached the result (from a computer that is about 3-4 meters from the router, in the same room) from NetSpot - I don't know what the signal strength was before. I am also uploading screenshots of the WiFi router settings.
I'm out of ideas on what to do, and I must admit that the drop in WiFi speed is somewhat noticeable.
