RT-AC88U requires frequent reboots

[Michael Salinger]

My RT-AC88U has several problems that I can't figure out. I'm on the latest firmware (3.0.0.4.384.20379), have tried factory reset, and the only settings I've changed are to disable airtime fairness and enable IGMP Snooping on both 5GHz and 2.4GHz (I have various Chromecasts and Google Home's on the network). I've also enabled adaptive QoS for streaming. When I reboot the router, everything works fine, but over time the following things happen:

• Devices on 5G can't access devices on 2.4GHz (printers, an IP camera, etc.)
• Internet speed slows. When first rebooting get ~200 mps (which my data plan allows). However over time this slows to about 10-12 mps...
• The admin page becomes inaccessible (just hangs when trying to access it)
• Eventually all traffic will stop.

Any ideas? I'm at my wits end here. The router worked fine for over a year and is just out of warranty.

What browser are you using and have you tried clearing its cashe and cookies? BTW your router has a two year warranty.

Chrome, but when it occurs it happens on multiple devices.

you need to reset the firmware and configure from scratch, there was an issue of a DMA transaction between the 2.4 and 5Ghz controllers failing going from 5-2.4 after the upgrade from 380 to 382.

I just did this the other day (factory reset). How do I reset/configure to ensure that this doesn't happen again? Does Merlin's firmware have this issue?
