R3 - losing Internet connection at random

Hello.

As in the title - lately my Internet connection has been breaking up at random, most often while playing video games, but it has also happened few times while I was simply browsing the Web.

R3 is my first Netduma router, which I've owned since before Christmas (got it for myself as a Christmas gift). Having said that, I've already had some strange issues with connection under the router before, but at the time it was not as severe as it appears at the moment; usually resetting the Net settings in Windows solved the issue for a while. (Before you ask - no, I didn't have any sort of issue with Net connection on old, ISP-provided router.)

Later, I've kinda switched my focus to single player games, which did not require constant internet connection, so I hadn't felt the issue.

Lately though, I've gotten back to both Call of Duty, and World of Tanks... and now connection issues have reared their ugly head once again. More so in Call of Duty than World of Tanks, though I have felt it there, too. CoD is bigger problem though, since as an avid Zombie player there, such connection breaks always throws me back to the desktop... and upon returning to the game I always lose everything I've taken with me the previous game, and my personal slot for weapon gets locked.

Would like for some advice, since I genuinely have no idea WTF might be wrong at the moment. Old router from ISP is used under the bridge mode, and I am hardwired to R3. Curiously enough, none of the mobile devices connected to R3 by WiFi appear to experience connection issues - it's only my PC.

Just in case, I am attaching the fresh logs, up to the latest time when connection broke down again.

Hoping to be able to finally put this issue to rest.

We believe we know what the issue is and it should be fixed in the next version. In the meantime, could you in DHCP settings, set the DHCP range to start at .50, then assign reserved IP addresses to devices between .2 & .49 so they're out of the DHCP range & apply. Also set the DHCP lease to 10000, apply, reboot from the interface, wait 4 minutes and see if that stops the disconnects.

Done as you asked. Just experienced another connection break, while playing World of Tanks.

Attaching newest logs.

EDIT: Updated with newer logs; just experienced four connection outages in a row, in 3 different matches in WoT.

Apologies for late reply.

Before your last message, I've experienced two more outages, one right after the other, while I was simply browsing the Web. So, my patience kinda ran out, and I've simply plugged back in the ISP router. Everything's been working fine on it.

After your reply, I've tried to switch connection back to the router, but... I've been unable to display DumaOS, and while I could browse websites, stuff like Discord wouldn't load either.

Today, in the morning, I've switched R3 off and went to work. As I've just got back from it, I've turned it on again, and plugged the cable back to see if it would go back to working properly. (I know I can probably restore everything by hard resetting the router, but for now I chose to abstain from this option.)

And the result is... as before - basic ability to browse Web, but can't access DumaOS, Discord, etc.

So, for now I'm thinking of just jumping back to ISP router, and just waiting till new firmware release to then test things out. (Can handle lack of Geofilter in CoD, since I'll be playing Zombies mode only anyway, so...

Fair enough if that's what you want to do that's totally understandable, firmware shouldn't be far off. What do you see exactly when you try to access the interface?

Attaching image; just your standard, run-of-the-mill 'Unable to connect' in my native language.

... Okay, this time, after getting back from work and plugging in R3 once more, it wouldn't connect at all to the Web. But previously, the error was the same. so...

Do you turn off the router everyday when you go to work? 

While connected to the router via a Windows PC, open command prompt, type ipconfig press enter and then post a screenshot of the results here please.

What firmware are you on for the R3? Your logs seem different from the most recent firmwares as your cloud download/sync is not giving a decrep error before refreshing?

Fraser:

Not usually, no. Most of the time it stays running 24/7. Made an exception once just now, during this issue.

Also, attaching image with ipconfig results, as requested.

Spdsk8race:

Using .41, the most recent one. At the very least the update button was inactive whenever I checked it out those few days ago.

  1. Right-click on the Network/WiFi Windows Network Icon on the PC on the bottom-right hand side of your screen
  2. Open Network and Sharing Center.
  3. Click Change Adapter Settings.
  4. Right-click your connection and go to Properties.
  5. Uncheck the box next to Internet Protocol Version 6 (TCP/IPv6) to disable it.

Then set a static IP on the PC with the following details

IP address: 192.168.77.100

Subnet Mask: 255.255.255.0

Default gateway: 192.168.77.1

DNS: 192.168.77.1

If you're not sure how to do this, you can check this guide: https://kb.netgear.com/27476/How-do-I-set-a-static-IP-address-in-Windows then try accessing 192.168.77.1 please and see if it works.

It works!

Done as you've instructed, and at the moment connection is there, I can access DumaOS, and Discord is also there. I've yet to play CoD or WoT, but after doing so will update this post ASAP with results.

Also, done as you've asked earlier and disabled IPv6 in both LAN and WAN Settings. Will update with further results after playing few games in WoT.

UPDATE: Played few matches in WoT, and so far everything's working. Will update further after giving CoD a try as well.

UPDATE 2: Only first match was interrupted, and even then I strongly believe this had more to do with server's instability than router shenanigans. Otherwise, everything's been working fine. The only worrying thing for me at the moment... seem to be the system logs, they're... well, check it out for yourselves, atttaching them. They seem to be like that the whole time now. Only caught that because I routinely went to check them after my first CoD match disconnected me midgame. Second check done just now, for comparison.
