@FrancescoM: Hi Francesco, here is an interesting Wifi problem for two users. Maybe you can have it analyzed to see whether there is a problem on the router side or with Apple.
5018 I have some older devices in operation. I am a vehement opponent of planned obsolescence.
I have now renamed the bands and set the iPad to the 2.4GHz band (now the ThinkPad also runs without any problems with ax).
Then did the speed test on the iPad with MySwisscom.
At 2.4GHz everything seems ok. Full 1GHz throughput of the modem, green result for the connection to the iPad.
At 5GHz the test does not produce any results.
It also seems to me that the iPad charges reasonably well at 2.4Ghz. At 5GHz the charging problems are as usual.
Maybe you’ve already written it, but how far is the router from where you use the iPad? And are there walls between the router and the iPad?
The 2.4 GHz band is massively slower, but the range is significantly better. The 5 GHz is massively faster, but not as great in range. And the speed drops very sharply in the edge area. And one thing you shouldn’t forget is that even if the router still brings the signal to the end device, the end device is already too weak to bring the signal to the router. This can also lead to problems. Only the customer doesn’t see it because the device shows that it is receiving a signal.
I understand that you did the speed tests with the mySwisscom app on the iPad. What happens if you do the tests at the same place with a mobile phone and the mySwisscom app? Same result?
I am still convinced that the problem is not on the IB3 side. The WLAN in the IB3 is a high-performance chipset from Broadcom with their standard drivers that is widely used worldwide. And Apple also (still) uses Broadcom for WLAN and Bluetooth in its end devices. There are no known hardware problems with the WLAN with the IB3. Unfortunately, I only have an iPad Pro 11″ from 2018 or 19. And everything works perfectly there.
I have now tried the MySwisscom speed test with the iPad right next to the IB3. It works smoothly there and charging is also quick.
Normally I’m about 4m away from the IB3 with a concrete wall in between. That will probably be the problem then. 5GHz WiFi doesn’t seem particularly robust, but that’s just the price you pay for the speed. 6GHz has even shorter ranges.
I’ll leave the WiFi bands separated for now. All laptops run on 5GHz (ax) and the old devices on 2.4GHz. I can live with that.
Thanks for the help in locating the problem.
4 meters is actually no problem. Not by a long shot. A wall shouldn’t be an issue either, unless it’s a very special wall, but that’s probably not the case.
Can you log in to the router menu, then turn on expert mode, then select Diagnostics on the left, then select WLAN in the middle on the right, then scroll to 5 GHz and then click on “Additional 5GHz WLAN DEBUG information”? I’m interested in RSSI per antenna and transmission power. By the way, I’m assuming that you haven’t reduced the transmission power in the router menu, right? This would be found in the WLAN menu item on the left.

I’ll get involved cheekily 😁

The values of over 15 dB are okay and absolutely normal, so not a hardware problem.

@Werner RSSI interests me more.
I also assume that the IB3 works as it should. I don’t think we can make any progress here without deeper analysis from the development team.
Sorry @jacobacci
