650/900mbps is the speedtest i get on the asus app and asus speedtest page. I tried every possible settings changes still same speed max im getting with my s22 is 400mbps 5-10 feet away with direct line of sight to the router. Using my laptop connected to the lan port 1 of my xt8 Im getting 600+mbps speeds using speedtest and fast.com. I have 3 units of xt8 setup as router only and no other device connected getting on 400+mbps speeds on wifi. Im ready to throw away my asus xt8. BTW my mesh unit before this is a Netgear Orbi RBK50 which actually is performing better than the xt8. Maybe the problem is my isp.
OK, this is good information. If the asus speedtest page, states you're getting 650/900 Mbps, then we know it's an issue with the wifi setup. The first thing I'd suggest is to isolate the problem.
1. If you have 3 XT8 units, turn off all units. Power the unit connected to the modem on. Leave the other 2 units off.
2. Ensure 5Ghz-2 channel is set up. This is the channel with the greatest bandwidth. If you do not have 5Ghz-2 set up do the following:
Check the following settings in your wireless settings:
a. Wireless Tab - General - Enable Smart Connect - Button should be Off
Separate 2.4 Ghz band and 5ghz band - after you separate the bands
You should have 3 bands, 2.4Ghz, 5Ghz, and 5Ghz-2
Create three separate SSIDs, Test 2.4, Test 5-1 and Test 5-2, respectively
Manually select a control channel for each band
Ensure the 20/40/80/160 is available for Test 5-2
3. If you have any of the following turned on, disable them for the test:
a. Adaptive QOS - Bandwidth Monitor, QOS, WebHistoy
b. AI Protection - Off
c. Traffic Analyzer - Off
4. Connect your S22 to the Test 5-2 (don't connect any other devices).
5. Connect to Speedtest.net and run your test connecting to the closest servers and using different servers.
Run the speedtest next to the router and then run a second test 5-10 feet away.
6. If you don't get expected speeds, I'd try a different control channel for Test 5-2. You can try a few different control channels, to isolate for interference.
7. If that doesn't resolve the problem, you can also try a different wireless client,. e.g., iPhone 14.
If you see numbers around 550/800 on Test 5-2, then you can power up one of the nodes. You didn't state whether you are using ethernet backhaul or wireless backhaul. Also, you didn't state how you have the nodes set up, whether they set up as AP, AI Mesh, Repeater. If you have it set up as Repeater, you will only get speeds around 300-400/350-450 Mbps. If you are getting 550/800+ with just the router, let me know how you have the second and third units configured (ethernet backhaul/wireless backhaul and AI Mesh/AP/Repeater).
