I've been experiencing the same issues since day one at the beginning of December.
Router version 4.7.5.1.83.8.263
I would like to try any firmware that may resolve this issue.
What are the symptoms?
Loss of throughput on 5GHz (can't even log into router unless switch to 2.4GHz band) I've tried different channels and spectrum analysis shows the router is alone on its current channel (58 80mhz).channel width also has no affect.
Router logs seem to show a MAC of a device being associated and disassociated several times in a short period when the issue occurs.
How frequently does it happen?
Usage dependent. I was away for 3 days and it was on fire 24 hours after my return before the fault reappeared. (it seems to occur during streaming)
Do the devices having problems appear to be connected or associated with the hub?
Yes
Is the hub status indicator normal/blue when the problem occurs?
Yes
Do you have the 2.4GHz and 5GHz channels merged (default setting) or split (different wireless network names)?
Tried both. Currently split
If the networks are named differently, does the problem only affect the 5GHz network?
Yes
Once the problem occurs is it persistent?
Yes
Do you have any devices wired to the router and does the problem affect them at the same time?
I do but they are unaffected
Are you able to reproduce the problem reliably?
I live alone so as mentioned above I believe increased traffic like streaming is causing the issue. The 5GHz band had not crashed while I was away for 3 days despite a Fire Cube, Firestick, smartTV and echo dot having an 'idle' connection. Yet within a few hours of streaming video 3 days later, the 5GHz band crashed.
Do you think you have a way of triggering it? Only as mentioned. I'd be interested to see what's happening with any allocated memory and internal buffers of the router. Does 5GHz traffic stay separate from 2.4 and wired on its own routing table? That's all that's happening, that part of the router just stops routing and it's a cold stab in the dark but it feels like there's an overflow somewhere.
Is the problem always resolved by rebooting the hub?
Yes
If so, how long does it take before problems recur? Usage dependent. Usually around 24 hours; however, I now believe it's more like within 3-5 hours of streaming video (when I'm asleep and in work it doesn't occur)
If specific devices are always impacted when problems occur, please provide details
All devices on 5GHz band lose connection. Android devices will report "no Internet" the Fire Cube will have the yellow connectivity error light, the fire stick 4k sometimes tries to take me to the log in screen of the router as if it's a hotel style open WiFi page
Have the devices experiencing problems recently received any patches that might correspond with the time the issue first occurred?
The newest addition to my network is the router itself as I'm a new customer (it was replaced too with little difference).
Please provide a description of your home network setup and all devices:
LG smartTV 5GHz
AVR (now on 2.4GHz as I moved the 5GHz channel on to 58 and it wasn't compatible - fault still occurred when I tried wired connection)
Sky Q and a Minibox (currently using wired connection and their internal radios have been disabled in the installer menu as I originally suspected interference)
