Speed on AX for 5Ghz is ~60mbps, no packet loss. Much better than 2.4 but 10x slower than my fiber capability.

BTW. I forgot to mention that the test with my secondary router was made directly connected to the router.

Modem from provider does not have WiFi.
For ax1100 router %packet loss is around 3.5% the 3 times that I run the test.

For my secondary router speed is much faster with 50mbps on 2.4ghz and and 500mbps on 5Ghz no packet loss.

I was not correct about the 5GHz. It is still only providing about 15% of the speed I should be getting. It worked fine with the secondary modem, but the main issue remains with the 2.4GHz, which is delivering less than 1% of my expected speed. Here is my current network setup:
Modem → AX11000 (Primary) → 2nd Router
All routers are connected via Ethernet cable.

For the speed test I am using:

The 5GHz network appears to be functioning correctly now.

Answering to your question. My primary router is connected directly to the modem. I have adjusted the 2GHz channels and widths based on the least congested zones and optimal configurations identified by a WiFi analyzer. Despite these optimizations, I am consistently receiving extremely low download speeds, specifically around 0.08 Mbps, while upload speeds remain relatively high at 20 Mbps.For diagnostic purposes, I introduced a secondary router and conducted tests on its 2.4GHz band, which I got significantly better results than my primary 2GHz connection. Interestingly, when I disabled the 2.4GHz band on the secondary router, the performance of my primary 2GHz network degraded again, dropping to an abysmal 0.01 Mbps for downloads. I conducted tests at a very close proximity approximately one foot from the primary router, and the issue persisted. Furthermore, using the Ubiquiti UniFi app, I confirmed that the WiFi signal strength around the router is strong, indicated by a “green” status. Another point to note is that the problematic network is currently configured as isolated.

I am not sure how I can resolve this issue?

Hello. I’ve also been testing the new AX1800 since it arrived yesterday. On WiFi, I’m getting approximately 1/20 of my ISP speed on 5GHz and even lower speeds on 2.4GHz around 1/40 of my ISP speed LoL. I’ve already tried many different configurations, adjusting channels, transmit power, and other settings. For comparison, I have another router that delivers speeds nearly matching my ISP’s rated speeds with a very similar configuration. It’s definitely the router. Does anyone know of a solution or have any suggestions?

Thank you for your quick response! I have one final question:

What is the difference between configuring the router in bridge mode versus using it as an access point? I understand that the PcWRT router can create multiple Wi-Fi networks based on specific needs, such as mine (for IoT devices and another for guests). Additionally, I want to mention that I am using the extra routers primarily to enhance coverage.
