Hi guys,
I have had problems with the 2.4GHz wifi for several months, requiring rebooting every day at least once.
The device is running with firmware v54.
Almost a week ago all the problems disappeared and now everything is back to normal and running smoothly.
The only action I took is upgrading the firmware of my Netgear wifi range extender.
A number of Android devices are connected to the network as well, including Chromecast, Android TVs, phones tablets etc (didnt perform any action on those).
I dont have any explanation for this, but the fact is that the network is now stable (back to the original state it was a few months ago), no rebooting is required, multiple devices are constantly connected to the 2.4 network.
Any ideas???
I believe your Android devices have upgraded themselves to the new version which has the wifi fix for this, it's a silent update so there's no prompt for it and you won't see a notification to say it's been updated either as you normally do with Play store apps. You can check this by going into your settings, Apps then scroll down to find Google Play Services and tap it - you should see a version number at the top. Version 11.9.75 is the current version and it has the wifi fix (11.9.74 was the first firmware to have it but that was a beta), 11.9.73 and possibly a couple of older versions had the wifi bug in it which would kill 2.4ghz on the D7000 (and some other routers). I don't know the exact date it was introduced as Google are generally keeping very quiet on it but I think it was around the end of November.
Google started rolling out the 11.9.75 update around the 20th January although not all devices received it immediately, my Galaxy Note 8 recevied it around the 23rd, another couple of Android devices were a couple of days later and one Android device only got it last week. Once all were showing the update I reactivated the 2.4Ghz wireless on my D7000 (I'd set up a temporary 2.4Ghz access point as the D7000 had become useless) and so far it seems to be stable again, I've been moving 2.4ghz devices back to it and they've still able to connect. I'm still on v54 and in December it was lasting minutes before the 2.4Ghz would fail and that's nearly a week it's been up.
The current newest production firmware is V60 but there's a beta V64 they're working on at the moment that has the chipset fix to stop the wireless failing if it gets flooded like the Google devices were doing, hopefully within the next couple of weeks we should see a production release of that. For now though if your Google devices are updated, you should no longer be losing wifi for that specific issue.
