your asus rt-ax86u is experiencing inconsistent wifi performance. speeds fluctuate between 100mbps and 750mbps depending on distance from the router, with noticeable drops when moving closer. this behavior suggests potential interference or signal quality issues.
Phy rate is 5700mbps on my phone. It's around 20 feet away, and the signal is 572 down to 598 up.
downstairs, the speed drops to 114 Mbps at 5GHz and 116 Mbps at 2.4GHz. The ISP router performed better.
Assuming the RT-AX86U is upstairs in a two-story home, it’s positioned centrally or slightly off-center depending on the layout. When testing at a distance of 20 feet, there are typically several walls between the test device and the RT-AX86U. Concrete or reinforced walls tend to block WiFi signals. Most home routers have omnidirectional antennas, but they struggle with vertical signal strength. To improve speeds where you experience slower connections, consider adding another wireless access point. Remember that both floors and walls reduce WiFi performance. 2.4GHz offers good coverage but limited speed compared to 5GHz, and it’s more affected by interference from microwaves, phones, and other devices. For better performance, prioritize 5GHz if possible, or use a mesh system to extend reach. Use a WiFi analyzer app to check available channels and avoid congestion. Save the router’s wireless settings screenshot, ensuring no sensitive information is visible. Turn off unused services and disable extra security features to free up CPU resources for smoother operation.
there were no obstacles blocking the path. the device 20 feet away was located in the same area as the router.
For the 2.4GHz antenna, set it to channel 6 and reduce the bandwidth to 20MHz. With the 5GHz antenna, choose channel 40 or 44 and turn off the 160MHz bandwidth temporarily. The 80MHz frequency should work adequately. Restart the wireless router and check speeds. Try not to connect to the 2.4GHz network if possible. Also, let me know what options are listed under "Wireless Mode" for each antenna.
On 2.4GHz, higher frequencies like 40MHz offer better speed but reduced range compared to 20MHz. It's mainly about trade-offs between data rate and distance.
