I would like to try the pushed 'fix' to the hub if possible please. I have been following this issue hoping a universal fix would be applied but as it is taking a while (understandably it seems complicated) anything that might help is now worth a try from my perspective.
Brief description of the problem, and how is masquerades itself. What are the symptoms? How frequently does it happen?
5GHz seemingly spontaneously stops working. Initially, 5GHz would stop working and devices would remain connected to the 5GHz network with no internet access but no new devices could connect to the 5GHz network. More recently, internet access is lost but devices can still connect. Only way to restore internet access is restart Hub 1.
2.4GHz is unaffected and continues to provide internet access as normal when 5GHz goes down.
Frequency is utterly random, sometimes weeks can go by with no issue but other times it can happen every few days or rarely twice in the same day.
Do the devices having problems appear to be connected or associated with the hub? Is the hub status indicator normal/blue when the problem occurs?
Hub status indicator is normal; no obvious association between devices and hub.
Do you have the 2.4GHz and 5GHz channels merged (default setting) or split (different wireless network names)? If the networks are named differently, does the problem only affect the 5GHz network?
Split - only the 5GHz band is affected, 2.4GHz seems unaffected.
Once the problem occurs is it persistent? Do you have any devices wired to the router and does the problem affect them at the same time?
Once the problem occurs internet access on 5Ghz is permanently lost; it remains this way until Hub is restated by disconnection from mains.
Are you able to reproduce the problem reliably? Do you think you have a way of triggering it? [for example waking a specific device from power save mode]
No. There is no way to trigger the issue.
Is the problem always resolved by rebooting the hub? If so, how long does it take before problems recur?
Rebooting the hub always resolves the issue so far; problems reoccur randomly in intervals of weeks, days or rarely more than once in a day. No pattern is discernible.
If specific devices are always impacted when problems occur, please provide details of which devices are impacted and which aren't i.e. manufacturer, model, variant and operating system version.
All devices connected to the 5GHz band are affected and once it occurs new devices which connect have no internet access on that band.
The devices I connected on 5Ghz permanently are an Amazon Echo 1 and Amazon Dot (first generation); iPhone 6S occasionally connects to 5Ghz. The problem can occur when these devices are actively being used OR when they are not.
Have the devices experiencing problems recently received any patches that might correspond with the time the issue first occurred?
No. The problem has been ongoing since I got the Hub 1 about 18 months ago or so ago and first tried to use the 5Ghz band.
Please provide a description of your home network setup and all devices in use including whether or not you're using any additional switches, Powerline adapters or wireless access points.
1 x Amazon Echo (gen 1) on 2.4 ghz.
1 x Amazon Echo (gen 1) on 5Ghz.
1 x Echo Dot (gen 1) on 5Ghz.
1 x Amazon Firestick (gen 2) via ethernet.
1 x Iphone 6S on 2.4/5Ghz.
1 x windows 10 laptop 2.4ghz
I have one powerline adaptor to a ethernet connected PC – but this is not the issue as the problem occurs even if I disconnect this.
