I just had the opposite experience. Since Rel. 6.x. The range and stability have become much better. To do this, however, I had to “separate” the two networks 2.4 GHz and 5 GHz using different SSIDs. Have you tried that yet? The choice of channel is also crucial. Depending on the environment, auto mode doesn’t work particularly well and you have to use a tool (e.g. inSSIDer) to find good channels and set them manually.
Thank you very much for your answer.
I can try the channel setting. Thanks for the tip.
Since I’m not a professional, I have another question:
If I separate the two networks I have 2 different SSIDs.
Which device do I connect to and which SSID? Or do I then have to record both SSIDs with Natel, for example, and the Natel automatically connects to the better one (if so, doesn’t the device always switch back and forth?)
Sorry for the many questions 🙂

Hello
There is currently still a small bug fix release being tested. It has already been rolled out to 10,000 customers and if everything continues to go well, which it looks like at the moment, then it will go out to all Internet boxes shortly. The release only affects the NP part and in particular a problem with WLAN is being solved, which can have a negative impact on the range in certain cases.
Basically, when it comes to measurements in the laboratory, the WLAN has improved significantly with the 6 release. We have updated the entire driver level with Broadcom. It couldn’t be more current. In reality, of course, many factors play a role in how much of the improvement actually arrives.
So. Please be patient because of the range issue.

Here again the reference to the new version of the app for the Internet Box:

For most wireless devices I only set up the 2.4 GHz, as the range of the 5 GHz is very limited. I set up both SSIDs on the iPhone 5 and it works without any problems. I don’t always check whether the device is currently actively connected to 2.4 GHz or 5 GHz. But I didn’t notice any annoying constant switching between the two networks. Since the behavior varies depending on the device and environment, you have to try it out yourself and find the best solution for you. When it comes to WiFi, there aren’t generally applicable rules for everything.
Hello everyone
I have two problems:
The DynDns doesn’t work for me (was already discussed once at the beginning of April): 
and secondly, when I try to switch on IP telephony in the Internet Box app on the iPhone, I always get the message that an IP subscription from SC is required - which is done automatically with the Internet Box.

Hello everyone.
Thanks for your answers.
Then another question comes up…:
Is the quote correct??:
“FW 06.01.13 will also appear on the well-known Swisscom support page in the next one to two weeks.”
This is not intended to be a complaint, but should this really be the case that the new firmware is rolled out everywhere StepbyStep (including those where everything runs perfectly) and for the others (like me, for example, with major WLAN problems) with the necessary knowledge about this Do you have to wait until the firmware can be downloaded?
Best regards and thank you for your efforts.

Maybe you have already solved the problem.
If not, I had the same problem.
The only thing that helped me was activating DHCP on the box. Set up VPN and DYNDNS and then deactivate DHCP again. Why it just happened that way for me is beyond me.

Hello
I noticed that the Forgotten Password option keeps getting activated automatically.
I have installed the 13/24 (latest) version.
Disable password recovery…
The following happens when I deactivate the option:
Forgot your password? Query password in Swisscom Kundencenter customer center
After a few days, however, the following automatically occurs again:
Logging in for the first time or forgot your password? Set new password
Maybe this has something to do with the settings of Kundencenter?
Anyone else have this phenomenon?
Thank you
