Router Dropping Internet Connection XR500
My connection keeps constantly dropping and is very slow I checked to see if my router needs and update and its on the lastest firmware v2.3.2.40 I can't find any solution to this and it's just very ...
I installed the new firmware earlier today to attempt to solve this same issue and am now showing version V2.3.2.40-C424a
However 6 Hours later I'm seeing the same issue crop up again. When it happensthe logs show:
[DoS Attack: TCP/UDP Chargen] from source: 184.105.139.101, port 55103, Monday, June 17, 2019 01:05:54 [DoS Attack: ACK Scan] from source: 152.195.55.219, port 443, Monday, June 17, 2019 01:04:42 [DoS Attack: ACK Scan] from source: 152.195.55.219, port 443, Monday, June 17, 2019 01:04:40 [DoS Attack: ACK Scan] from source: 152.195.55.219, port 443, Monday, June 17, 2019 01:04:38 [DoS Attack: ACK Scan] from source: 152.195.55.219, port 443, Monday, June 17, 2019 01:04:36 [DoS Attack: ACK Scan] from source: 152.195.55.219, port 443, Monday, June 17, 2019 01:04:34
I spoke with my internet provider earlier today about this issue and they were insistent that the internet outage was 100% on my router as they've never seen any type of drop from my Modem for over 30 days. I tried disabling the DoS protection right as the issue occured but it continued to connect and disconnect just like it has been doing to me for months. The internet goes out for 10 - 40 seconds and then comes back, see here my logs from "Net Uptime Monitor"

This is very upsetting to find out that my internet troubles can't be blamed on "the man" but my $300 router! Please help me solve this before I'm forced to Buy a different router and attempt to sell this one to recoup some of my losses.
Just checking: did you do a factory reset after the upgrade?
I did not do a factory reset after the upgrade, is that something I should do? It wasn't included in the firmware update instructions.
It wasn't in the instructions but since we're trying to fix some issues in your case, doing a factory reset makes sense. Any settings that were causing issues will be wiped in the process.
But of course you'll lose your device names and traffic prioritization so we could try some other stuff first.
- I don't have any prioritization set up. I have QoS completely disabled because every test I ran regardless of setting lead to a significant reduction in max speed capacity on my pc. I couldn't once hit my speed cap when I wanted to be able to, but I don't have enough devices fighting for priority to even benefit from getting it working properly to care.
The firmware update seems to have alleviated one set of interruptions that had been happening between 4:45 and 4:50 every morning consistently for a month. But the random outages throughout the day continue and they continue to occur when DOS attack entries are being logged.
I'm not fully against doing a factory reset but I am curious what other troubleshooting steps you'd suggest before going that route.
Also, side note, the firmware update seems to have removed the button to download my log as a .txt file, I now just have refresh, send and clear.
