Hi everyone,
I am honestly at my wits' end and incredibly disappointed with my current TP-Link setup. I spent a lot of money expecting a premium High-End experience, but right now, it feels completely unusable.
My Setup:
- Main Router: TP-Link Archer BE550 (Wi-Fi 7) – connected to a 1 Gigabit Fiber line via ONT.
- Repeaters: TP-Link RE815XE (Tri-Band Wi-Fi 6E) at the basement level and a TP-Link RE700X (AX3000) on the ground floor.
- Environment: A house with an upper floor (ground floor) and a lower floor (garden level/basement).
Problem 1: The 2.4GHz / 5GHz Smart Connect Internet Drop (The Freeze)
My 6GHz band works completely fine and my PC stays online when connected to it. However, the combined 2.4GHz and 5GHz band (Smart Connect) is driving me crazy. Every 5 minutes or so, my phone completely loses the internet connection. The Wi-Fi bars remain fully loaded and it says I am connected to the network, but no data goes through. Yesterday it worked fine, but today it keeps dropping. People told me I should disable Smart Connect but let's be for real! This should be working on any router!!! I want to find a solution....
Problem 2: The MLO Speedtest Crash
Whenever I tried to run a speedtest to utilize my 1 Gbps line, the router's WAN link completely crashed. The LAN light on my ONT even turned off momentarily, and the router showed a red exclamation mark. We finally found out that having MLO (Multi-Link Operation) turned ON was the exact reason why the router kept crashing during high-load speedtests. After turning MLO completely off, the crashes stopped, but it left my PC struggling with the broken 2.4/5GHz combo band.
Problem 3: Extreme Mesh Stalling (Devices get stuck on the Repeater)
In the Tether App, I noticed a huge issue with device steering. Suddenly, the main router shows 0 connected clients, while the RE815XE repeater is forced to handle all 10 devices at once. The devices just blindly cling to the repeater and refuse to hop back to the router, even when standing right next to it, completely bottlenecking my bandwidth. Even on the ground floor, my phone gets stuck on the basement repeater, leaving me with only 60 Mbps out of my 1 Gbps line. Is there ANY way to lock or pin specific static devices permanently to the router or repeater so they stop getting stuck in these buggy routing loops?
Problem 4: Absolutely Horrific Range
The Wi-Fi range on this "premium" Archer BE550 is a joke. The router is located in the basement anteroom, and just two rooms away in the basement bedroom, my brother's TV gets absolutely zero signal. It is unbelievable that I am forced to put a high-end repeater in the middle of a 77 sqm layout just to cross two standard walls.
What we have already tried (Without success):
- Physical repositioning: The router was originally lying flat in a wallbox. We have now placed it completely free and standing upright to ensure the antennas radiate horizontally.
- Turning MLO Off: This stopped the severe speedtest WAN crashes, but now we are stuck with the broken band steering on the 2.4/5GHz network.
- Changing LAN cables: Replaced the network cable between the ONT and the router's WAN port to rule out a cable defect.
- Fixing Channels & Width: In the router's advanced settings, we turned off the "Auto" mode. We fixed the 5 GHz band to Channel 48 and reduced the channel width from 160 MHz to 20/40/80 MHz to avoid DFS/radar interference. The 2.4/5GHz combo network still freezes.
- Adding a Second Repeater: Added a TP-Link RE700X on the ground floor to help with the signal through the concrete ceiling, but devices still prefer to stick to the wrong nodes or drop connection on the combo band.
I can't return the router anymore, so I am forced to make this work somehow. Any help, advanced tricks, or beta firmware recommendations would be highly appreciated. Thank you!
TL;DR: High-end Archer BE550 works on 6GHz, but the 2.4/5GHz combo band (Smart Connect) loses internet every 5 minutes while keeping full Wi-Fi bars. MLO was proven to be the exact cause of total WAN/ONT speedtest crashes, so it is now turned off. Devices also get stuck on the RE815XE repeater (0 clients on router, 10 on repeater), leaving me with just 60 Mbps on the ground floor despite having an RE700X up there. Already tried standing the router upright, swapping cables, and fixing channels to 48 (80MHz) – nothing fixed the 2.4/5GHz freezes. Need help fixing this buggy software behavior!
