How often is it happening? Does that mean you've split the bands so you can connect to 5G specifically? If so, you're not experiencing the issue over 2.4?

I've given you Early Access so you can upgrade to the firmware there to see if it continues https://forum.netduma.com/forum/151-netduma-r3-early-access/

Wife just told me today just happening. I use the router on smart connect her IPad connects to 5g it keeps telling her no internet connection. 

 

I used my pc to connect to 5G only and seems 5G doesnt work at all even on my pc and kicked all devices using 5G to use 2.4G

 

Thank you am downloading and testing it out now.

If you're using it without having split the bands then you can't force it to use 5GHz or 2.4GHz, it will use whatever is needed based on your requirements at the time so it will switch between the two automatically, some devices don't like that switching though. Split the bands, name them individually then connect to 5GHz specifically and see if it works

Problem is any device using 5G it will automatically kicked them out and a cause drops.

I even tried to split them and wouldn't let me connect to 5G my pc says cannot connect to wifi.

Everything was just fine yesterday. 

 

I tried to connect again to 5G and wouldn't let my pc connect.

 

As of right now. I disabled 5G and used my devices as 2.4G everything works as for my pc i use my ethernet cable.

Have you got 5GHz set to 160Mhz width? If so that will be why, set it to 80Mhz max and it should work fine again. Even if you don't have it set to that, make sure to set it manually to a width that isn't 160.

Fraser,

It works now am able to connect to 5G now..  all i did was turn router off for 10mins and everything is back to normal, am able to use 5G on auto 

[Netduma Fraser]

Good to hear, thanks for the update!

[Don Gordito]

Fraser Question, whenever i download a game from steam it disconnects my wifi then reconnects. it only does it with steam is there a bug?

 

only reason am asking is because it did it again so am forced to use ethernet to download.

[Netduma Fraser]

Set 5GHz like I mentioned previously rather than auto and see if that stops it please. Are you utilizing Congestion Control? That should prevent it using all your bandwidth and potentially making that happen. You're not prioritizing downloads are you?

[Don Gordito]

i set it seperately as you mentioned and i disabled smartboost and disabled congestion control and it still happens BUT it only happens when downloading large files using 5G,

 

[Netduma Fraser]

Disabling Congestion Control would be the opposite of what to do, re-enable it, set to Always and try with 70% for download & upload, do you get the same issue?

[Don Gordito]

where do i disable it?

 

[Netduma Fraser]

How did you disable it previously? Disabling SmartBOOST fully from its menu would disable Congestion Control so re-enable it. Then adjust Congestion Control in Ping Optimizer > Advanced.

[Don Gordito]

yeah its still kicking me off while downloading a large file on 5G anyways am going to return it.

 

it's a bummer.

[Netduma Fraser]

Okay fair enough, I'm sure we could solve it given more time but I'd suggest contacting [email protected] fairly quickly then as you said you bought it 3 weeks ago.
