Issues I’m seeing regularly:

[Sergejs Kotovs]

• Packet loss during normal use and gaming

• Internet connection drops by itself (the router loses connectivity)

• Wi-Fi devices take a long time to load pages/apps or reconnect

• Overall performance is inconsistent and my kids complain daily (streaming/online apps lag or fail)

This is a household of four people, so the router should easily handle typical family usage, but it constantly causes problems. At this point it feels like something is wrong with the firmware or stability.

Could you please advise what logs/settings you need from me to troubleshoot this? Also, if you have a newer firmware build or a beta version that improves stability, I’m willing to test it.

Thanks,

• Where are you measuring the packet loss?
• Are all devices losing connection? Does it come back by itself or do you need to reboot? How often is it happening?
• What is the model of the modem/router the R3 is connected to and how have you set that to ensure all traffic flows to the R3? E.g R3 in its DMZ, modem/bridge mode
• Are ALL devices connected to the R3?
• What are the speeds you pay for/receive? 
• Have you entered those speeds into the router?
• How have you setup Congestion Control?
• How have you setup SmartBOOST?
• What game are you playing?
• What platform are you playing on and how is it connected, via ethernet or WiFi?
• How have you setup the Geo-Filter?

I've given you Early Access so you can try the firmware there: https://forum.netduma.com/forum/151-netduma-r3-early-access/

In Settings > DHCP > Add Rules > Select Device > Save. Do that each device you're noticing the disconnects on. Then in DHCP > Advanced change the lease time to 10000, save, reboot the router from the interface and see if it happens again please.

For WiFi:

• Split the bands, give 2.4/5GHz different names and apply - you'll want to connect to 5GHz specifically for speeds
• Use a WiFi analyzer to find the least congested channel and change to that
• Experiment with the widths to see what gives better results
• Ensure it's in an elevated position - not on a metal surface
• Ensure there aren't any electrical / wireless devices e.g headphones etc within close proximity ~3 feet if possible
• Set the antennae to this position _ | | _

Hi, quick update.

I’ve applied your DHCP suggestions:

• Added DHCP reservations for all devices where I noticed dropouts

• Set DHCP lease time to 10000
  Now testing under load.

I also seem to have found a major cause of packet loss on my side:

• Setup: Telekom DSL → DrayTek Vigor 167 (bridge modem) → NetDuma R3 (PPPoE)

• Manually set MTU to 1492 (Telekom PPPoE)
  After setting MTU, packet loss disappeared (currently 0%).

Wi-Fi changes:

• Split SSIDs into 2.4 GHz and 5 GHz

• Set channels/band settings manually
  Stability looks better so far.

My household load:

• Family of 4, typically 5 devices actively streaming/using bandwidth (Netflix/YouTube etc.) while I game (wired), plus overall ~8 devices connected (phones, 2 TVs, 2 PCs, console).
  Question: is R3 hardware expected to handle this load without instability if configured correctly?

Remaining issues:

• Bufferbloat results are still poor / inconsistent.
  Even with Ping Optimizer/Anti-Bufferbloat set around 90/85 (sometimes 90/90), speed tests inside the system show very low throughput, and still show latency increase under load.

• Ping Optimizer auto-detect/auto-adjust fails (it reports it can’t adjust/optimize correctly).

Could you advise the best way to fix:

1. inconsistent/low throughput during bufferbloat tests,

2. latency increase under load despite conservative QoS settings,

3. Ping Optimizer auto-adjust failing?

I’ve already sent logs about the errors I’m seeing. Please check them and tell me what the errors mean and what settings you recommend for my setup.

Thanks.

• I play Call of Duty: Black Ops 7 (PC).

• Geo-Filter / ping display does not show ping for any CoD servers (Warzone/BO7). It used to occasionally show pings before, now it never does. Is this expected behavior with CoD servers (ICMP blocked), or could it indicate an issue with Geo-Filter/ping engine on my R3?
