What does it look like if you check it at the link below?

What firmware is on the IB2?

The following experiment would be ideal for isolating the error:

- Tests on your IB2 with another WLAN device (smartphone, laptop)

- Tests with your iPad on a different WLAN

This way you could narrow down whether the problem is with the IB2 or the iPad.

Can you arrange something like that?

Has anyone in the neighborhood installed a new WiFi or changed the channel?

I would try changing the channel manually. You should also be able to do a scan to see which channel is the most suitable, but this is not always precise since the measurement location is the router itself. Otherwise try it out.

@ryma

WLAN problems are very complex and often require a lot of effort to resolve.

But yes, replacing the box is of course also an option to then confirm or rule out this as the cause of the error.

@ryma

If you have to buy a Internet-Box 3 expensively, you can also look at Ricardo.

Or you can buy the Internet-Box 3 directly.

One more thing comes to mind. Didn’t you happen to reduce the transmission power in the WLAN settings? Then it wouldn’t be surprising if the distance decreased significantly.

@ryma

Can you please also post a screenshot of the debug information from the 2.4 GHZ band here.

ryma

Strange that your box says transmission power 2× 0, it looks like this to me, but it is an IB3:

The IB2 may be defective.

Have you already done a factory reset (keyword paper clip)?

Is the IB2 on the current firmware version?

If the router is defective and has a warranty, then you don’t have to pay for it. The 2.4 band really doesn’t look good.

Call the hotline and in this case have the router replaced.

@ryma

I don’t assume you still have warranty on the IB2. But with a bit of luck you can get an IB3 at a reduced price in the Swisscom shop.

You can also cancel the Anschluss and then order it again, then you will get an IB3 for free 🙂
