ASUS NETWORK QUESTIONS

[tiomiguel]

I have an RT-AX82U as main router and one RT-AX55 in AP mode. Main router is in garaje due to WAN location. So, WIFI coverage is done mainly by RT-AX55 in home center placed.

At garage there is also a solar inverter. Solar inverter connect by WIFI but also crates a WIFI NETWORK IN THE SAME CHANNEL for direct access to the inverter. There is NO WAY of changing this.

I have some questions, all oriented to maximum WIFI coverage

1) If I do not have WIFI 6 devices, should I disable WIFI6?

2) I have main router and AP with the same SSID but different channels. ¿Whta channels should I Choose? 1-6? 1-11 for min overlapping? AP doing main WIFI job should be in 1, 6 or 11????

3) I have attached solar inverter to garaje router for solar inverter WIFI being in another channel than RT-ax55, FOR DOING SO, i PUT it in RT-AX55 black list. ¿there is other way to do solar inverter prefer garaje router???? I have seen BIND option but I have not AX55 as IMESH NODE. What is the effct of BINDING solar inverter to main router?

4) RT-AX55 does a good job but I need a few more coverage. I could put another AP in low power mode or upgrade the RT-AX55 for a larger coverage ASUS AP ¿What is longest budget coverage AP ASUS? I am in Europe. RT-AX82U is in LOW power mode and RT-AX55 in BALANCED POWER MODE.

You can leave AX enabled, it's backward compatible to older clients. Disable AX only if you have issues with some of the clients.

Whta channels should I Choose?

This depends on your wireless environment. Run your equipment on Auto for some time and lock the channel used most of the time.

Don't worry about the inverter's Wi-Fi. It's just an SSID with low bandwidth used, any channel it uses won't interfere with your Wi-Fi.

RT-AX55 does a good job but I need a few more coverage.

Switch the AP to Performance in Wireless Professional settings and try again. You can try Ch.100 on 5GHz for higher Tx power as well.

AP doing main WIFI job should be in 1, 6 or 11????

High bandwidth clients connected to Wi-Fi must be using 5GHz band. Available non-DFS channels in Europe are 36-48. For low bandwidth clients on 2.4GHz band you can try common 1-6-11 suggestion, but not mandatory. It works well for wireless planning when you control all the APs around. This is not the case with residential Wi-Fi.

I have read increasing TX power (performance) is bad.

SSID created by inverter is in THE SAME channel inverter connects to mi WIFI

I have read increasing TX power (performance) is bad.

In your region 5GHz Tx power is limited to 200mW on non-DFS channels anyway. Increasing it over 400mW doesn't make much sense indeed, but you can't get there unless you try non-guaranteed to work DFS range with up to 1000mW limit. This doesn't mean your router will reach 1000mW. It will use whatever the radios limit is. Your Balance setting is perhaps affecting negatively the usable range. Better try the default Performance and see if it improves the situation.

It doesn't matter what channel it is using. What matters is what bandwidth it needs and I believe for this device it's minimal. It won't affect your home Wi-Fi performance in any way. Don't look at Wi-Fi Analyzer type apps. They show the channels APs around are tuned to, but don't show the channel available bandwidth. Mostly useless for Wi-Fi planning. Your best channel may be the one with the most APs seen around sending just beacons but not doing any large data transfers.

 

[tiomiguel]

Default setting is BALANCED. All I say is for is for 2,4 Ghz. 20 of my 25 clients are in 2,4 Ghz

¿What is

Are you in Spain? I have a house there and using 4x Cisco APs on very low power. This is a different strategy for more even Wi-Fi coverage and better roaming. This is more expensive solution though and needs some better networking and Wi-Fi knowledge to setup and tune. If all your clients are 2.4GHz only - the power limit in Europe is 20dBm or 100mW and you have channels 12-13 available. You can disable AX on 2.4GHz band for better compatibility. Use 20MHz channel bandwidth at all times.

 

[tiomiguel]

Yes I am in Spain. But you say me to use performance mode (max tx power) and now you use low power in your AP,s... ¿What is the best, performance or low power?

 

[tiomiguel]

I have read not to use channel 13 because overlap channel 11

 

[Tech9]

But you say me to use performance mode (max tx power) and now you use low power in your AP,s

Correct. You have one main AP, in my case I have four spread around the property. It's a different setup.

You'll never make your system better without trying yourself what works best in your unique Wi-Fi environment.
