Do you have any devices still connected to your TP link? Set the speeds to 1000/1000. What does Ping Heatmap indicate your best ping to the game would be? What ping did you get previously when using the TP link?

You would just need to do it on the R3 as you've done the passthrough so all traffic is going to the R3 unimpeded by the modem

Are ALL devices connected to the R3? What are the speeds you pay for/receive? Have you entered those speeds into the router? Is Congestion Control set to Always or Auto? How have you setup SmartBOOST? What platform are you playing on and how is it connected, via ethernet or WiFi? Are you actually getting the German server when you get that ping? What country do you live in?

I wouldn't put so much value on the bufferbloat test and getting those values - bufferbloat only occurs when the network is saturated which can't happen when Congestion Control has been lowered. That being said, I assume you were trying in multiples of 10 from 100? Go in multiples of 10 from 95% instead and you may get better results with higher values.

Do you still have the XR1000 to try with on this updated version of GTA to see if you get the same issue?

Is it dropping out when you change the WiFi details? If so you'll need to reconnect to the WiFi using the new details and then you can continue. If not, try setting up via the Nighthawk mobile app instead

Good advice above. Also you mentioned you used the XR and you didn't have the disconnect problems, did you still have all the other odd issues with the XR or was literally everything working as expected?

It's very unlikely to be honest - you said you tried it with QoS off before, did you disable this from the SmartBOOST menu? It should have rendered the SmartBOOST and Congestion Control sections inoperable. If not please try it doing that as it's the proper way to disable it. You can also disable DPI & BI in Settings > Troubleshooting > Advanced

Could you provide a screenshot of the Geo-Filter with what you see when it happens please along with the ID of the server in NA

It's essential the Geo-Filter is enabled before the game client i.e. Steam etc or the game have been launched. If you change Geo-Filter settings when you're on the game then you will need to restart the game for those changes to take effect, otherwise it will use the previous Geo-Filter settings and appear not to be working. You'll need Ping Assist off as well. If it continues please get the ID for one of these NA servers and we can have a look

Presumably you yourself don't have these issues when hosting? I'm not sure how NPCs instakilling could be network related unless its delayed and then a torrent of bullets come out instantly? If you host but then don't move or do anything at all while the others play do they still get the issues?

It's worth trying a few times as it's not always successful right away. I have seen 2.4 & 5GHz give out in the past while 60 still works so that is likely unfortunately. We've not brought out our own router capable of those speeds at the moment sorry to say

Good to hear, thanks for the update!

I think the above method will be your best course of action now. It's impossible to say really as both the software and the hardware are on the older side now.

I've given you Early Access so you can upgrade to the version that resolved it for the above user https://forum.netduma.com/forum/151-netduma-r3-early-access/

It's working now, if you're not seeing it then resync the cloud in the Ping Heatmap menu

The servers aren't down, Ping Heatmap isn't showing the locations but that is on our side, it's not a reflection of if servers are online or not. It does not affect your ability to play the game or use the Geo-Filter

Force some different servers, the ones you're playing on may be under more heavy load

We're aware of Heatmap and will be updating it via the cloud this week but it will not effect your ability to use the Geo-Filter.

It's a tricky one, I would have expected you to get access with what you've tried so far - the only thing that might have impacted it is if you were trying to access the interface quickly each time. Do this and hopefully it'll fix both issues: Connect via ethernet, disable the WiFi radios entirely so 2.4/5GHz wouldn't be able to broadcast then reboot from the interface, close the web browser/interface tab completely, wait 4 minutes then access (can you access properly yet?), then enable the WiFi radios, reboot from the interface, close the web browser/interface tab completely, wait 4 minutes then access - does the WiFi and interface access work then?

We are aware and due to the holiday in the UK the update for it has been delayed but it is coming and it won't impact your ability to use the Geo-Filter.

Not yet, given the time of day on Thursday I passed over the serial and due to the bank holiday there hasn't been much time for replies but we'll chase it and get back to you when we know more
