After reviewing your case with our tech department this is their input:
Our device is certified to work at 5 GHz. However, at times it can happen that certain devices are just not working well with each other.
I can send your device to the repair center to be checked. If the technicians confirm that the 5 GHz works well, then we will have to assume there is an issue with your specific router.
Please let me know if you wish to send your phone to our repair center to have it checked.
In the very first support request I described that this only happens with Fritz!Box routers and linked to this thread. I repeated this in every interaction with the support person. Amnesia?
Anyway, I give up. For FP the problem is simply that ācertain devices are just not working well with each otherā. Nothing to be done about it. Certainly not by them.
The latest version of FRITZ!OS is 7.27, does your AVM router work with it already? The release notes say something about āimproved wireless stabilityā:
Well, no, not in my experience. I see a lot of devices as Iām in the unfortunate position of being The Tech Guy for my friends, family, and work colleagues.
Iāve never seen a USB problem that could not be attributed to a faulty (or charging-only) cable.
Iāve once seen a WiFi incompatibility that I couldnāt fix, but that involved a terrible ancient no-name router that should never have been used in the first place. AVM routers, on the other hand, are comparatively rock solid. The fact that FP3s (and FP2s I think) have problems with them in particular stinks.
Bluetooth can do strange things, granted, but Iāve seen nothing that couldnāt be fixed by simply re-pairing. Except with my FP3, where BT always refuses to turn on for several times after a reboot or coming out of airplane mode, and then turns off again when I start playback.
I have an FP3 whose quirks I can handle. My wife has one because Iām there to troubleshoot it, to install a decent camera app, to tighten the screws when the fingerprint sensor stops working again, to change the WiFi settings so it works with AVM routers, etc. Iād never recommend it to anyone else because all half-decent phones Iāve seen have none of the FPās problems.
I want them to get better. I want sustainable phones to be as reliable as something made by Apple or Samsung. For that to happen FP has to acknowledge that the problems exist. Letting them hide behind some cop-out line like the one cited above doesnāt help in my opinion.
Please ask Vodafone for an update immediately. Version 7.20 of FRITZ!OS is very old, and a lot of (stability) issues were solved and improvements were done in the meantimeā¦
@DeepSea Thanks for the unintended prompt, I thought Iād check my FRITZ! 7530, to better understand the last few posts and it had automatically updated to 7.27 on 20.05.2021
Youāre obviously not a Vodafone customer . They sold the 7.20 rollout as a huge achievement even though it was way outdated even then. Before that, I donāt think there was any update in years. But as I said, I see a lot of devices, including frequently updated AVM routers, and the FP3 has the same problems with all of them.
I know I should get my own router, but Iām not too keen on jumping through the hoops Vodafone has hung up in order to keep me from doing it.
Thereās movement ā¦ FRITZ! Labor Neues/Verbesserungen | AVM Deutschland for FRITZ!OS beta version 7.39 lists quite a bunch of improvements in the 5 GHz WiFi department regarding e.g. manual channel configuration, radar detection and the auto channel feature.
I would try this beta to see whether itās a fix for the issue, but itās not available for my box (6490 Cable).
Anybody else feeling adventurous ā¦ remember to backup the state of your FRITZ!Box before installing any new FRITZ!OS version (not only beta) and ideally get install files for the current FRITZ!OS version for your box at http://download.avm.de/fritzbox just in case. Canāt hurt.
