I purchased Asus TUF Gaming AX4200 as a replacement of my outdated Asus DSL N17U. (Moreover I am not using DSL connection anymore.)
Situation:
- Some devices will not connect to wifi offered by AX4200.
- Other devices work flawlessly. (incl. Windows, mobile phones, androids, Chromebooks as well as home appliances like dryer, washer or fridge.)
- Originally I planned to go for 5GHz wifi only but home appliances often support only 2.4GHz network (resp. 802.11b/g/n), hence I ended up with 2 SSIDs.
What happens:
- Some devices fail to connect any of those SSIDs:
- Google Nest Hub (Supporting 802.11b/g/n/ac) ❌
- iRobot Roomba supporting only 2.4.GHz ❌
- Google Nest Hub Max (802.11b/g/n/ac) .... to be tested ❔
What I expect to happen:
- They'll be able to connect at least 2.4GHz SSID.
What I have tried so far:
- Disabling Ai security: No effect. ❌
- Shortening the network passwoord: No effect. ❌
- Disabling 802.11ax for 2.4GHz SSID (whatever it means): No effect. ❌
- Provide the additional (2.4GHz) SSID from the legacy DSL N17U: Devices are able to connect to such SSID flawlessly ✅
- Factory reset of Nest Hub and Roomba: No effect. ❌
- Align settings of 2.4GHz network on TUF Gaming AX4200 with settings on DSL N17U + disable extra features: No effect. ❌
- Taking devices closer to router: No effect. ❌
- Narrowing range from 40MHz to 20MHz: No effect. ❌
So far it looks that devices' attempst to join wifi network are "rejected". Any idea, what happens and how to solve it?
Thanks!
