After updating to the latest v4.9.0 firmware the other day I have had consistent and major network connectivity and stability issues as websites would often show up as ERR_ADDRESS_UNREACHABLE and otherwise leave all services (often including the router’s own interface) entirely unaccessible from my desktop computer connected over ethernet. Wireless devices such as my phone also suffered network problems and would result in my phone using cellular data because it could not get an internet connection out of Wi-Fi. I have since rolled back the firmware and restored a backup I took right before the firmware upgrade to the router as a mitigation effort for the time being until I could solve my problems.
I had tried toggling network acceleration on/off and also switching between software and hardware acceleration to no success, trimming my adguard blocklist even further showed no change, and no other troubleshooting steps revealed any solution. I didn’t change any settings once I upgraded and so the only thing that I changed was the firmware version when I upgraded and so I believe the upgrade was the root of my problems. Restarting the router would temporarily fix some of my internet problems like on my desktop before eventually websites would become unreachable.
Anyone else having these issues or know of a potential fix?
Issue has failed to replicate since, apologies for no response I've been waiting for the same issue to occur so I could get logs. I've had weird packetloss or other weird connection interruptions over wired that impact online gaming, VOIP, or other real-time applications quite seriously, although I'm still ruling out if that's due to the router or issues in other systems presenting since. If I can catch it happening with anything notable in logs then I'll create a new thread for those issues.
