Graham Posted June 20, 2019 Share Posted June 20, 2019 My Netduma keeps dropping it's connection every ten minutes or so I then have to reboot it to restore the connection which works for another 10 mins or so. My physical setup is BT Router/Modem > Ethernet cable to port 1 on the Netduma then I am using the wired LAN and WIFI of the Netduma for my office kit. I can't link my Netduma directly to the WAN connection as it's via copper now RJ45 however the BT Router has internet when the Netduma fails. Attached is the log file of the Netduma. One other thing I noticed is the time on the Netduma is 1 hour behind my PC time but I can't see a way to change this and not sure if it's part of the issue or not. log-1561023079025.txt Link to comment Share on other sites More sharing options...
Netduma Alex Posted June 20, 2019 Share Posted June 20, 2019 Is IPv6 turned on or off in settings? It should be off. Link to comment Share on other sites More sharing options...
Graham Posted June 20, 2019 Author Share Posted June 20, 2019 It was on. I've disabled it now will see if that helps or not Netduma Fraser and Netduma Alex 2 Link to comment Share on other sites More sharing options...
Graham Posted June 20, 2019 Author Share Posted June 20, 2019 Disabling IPv6 didn't help. I've also set the WAN Ip statically on the Netduma still drops the connection Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted June 20, 2019 Administrators Share Posted June 20, 2019 Is the BT hub in router or modem mode? If possible could you put this in modem mode please, otherwise put the router WAN IP address found in System Information into the BT hub DMZ and then disable the BT WiFi please. How often do the disconnects occur? Is it on both wired and wireless devices? Link to comment Share on other sites More sharing options...
Graham Posted June 20, 2019 Author Share Posted June 20, 2019 I've now added then Netduma to the DMZ the BT hub is in router mode I cannot disable the WIFI as it's used by devices in the house. the netduma lives in my outside office and provides wried and wireless to my office devices. Disconnects are occuring less often since turning off IPv6 and setting the IP of the netduma to static I'll update tomorrow at some point with how it's working.

Administrators Netduma Fraser Posted June 20, 2019 Administrators Share Posted June 20, 2019 Okay keep us updated, do keep in mind that the QoS on the R1 won't be as effective as it's not controlling all devices in the home. Link to comment Share on other sites More sharing options...
Netduma Alex Posted June 21, 2019 Share Posted June 21, 2019 Yes theoretically it would be better to have the Netduma in the house and the BT Hub in the office, but of course if the BT Hub has better wifi, I can understand why this wouldn't be ideal.

Graham Posted June 24, 2019 Author Share Posted June 24, 2019 Trust me the BT WIFI is crap however it's a copper modem so I can't use the Netduma to connect to the ISP as it's a cable modem. So I still have the dropout issue it now runs for about an hour or so no issue before dropping. I have left downloads running over night as well and they finish and are large downloads with my bad speed the link must be re-establishing itself after a while.

Netduma Alex Posted June 24, 2019 Share Posted June 24, 2019 Oh so the BT is a combined modem and router, I see. So the Netduma has a Static IP set in the WAN settings, but have you set the Netduma's IP as static/reserved on the Home Hub? Link to comment Share on other sites More sharing options...
Azlios Posted June 25, 2019 Share Posted June 25, 2019 Any chance you can see WiFi connections named BTWifi-with-FON or BTWifi-X? Link to comment Share on other sites More sharing options...
Graham Posted June 25, 2019 Author Share Posted June 25, 2019 Alex yes I have the Netduma IP set to static on both itself and the BT hub. Azlios yes I can sometimes see BTWIFI-with-FON but not always Link to comment Share on other sites More sharing options...
Netduma Alex Posted June 25, 2019 Share Posted June 25, 2019 Hmm that's interesting. When you lose connection from the Netduma, that's for wired devices as well as wireless? Link to comment Share on other sites More sharing options...
Graham Posted June 25, 2019 Author Share Posted June 25, 2019 yes for both wired and wireless. The Netduma hasn't crashed and the Netduma wired and WIFI is still working but for some reason it can't get to the BT Hub and I cannot connect to the BT Hub GW 192.168.1.254. once I reboot the Netduma the link comes back instantly and works again. The issue may well be with a setting on the BT hub but I have no idea what could be causing it. Link to comment Share on other sites More sharing options...
Graham Posted June 25, 2019 Author Share Posted June 25, 2019 OK a correction to my previous post. the Netduma just stopped again and while my laptop was still connected to the WIFI network I was not able to ping my wired NAS which is on the same subnet so when the Netduma has the problem it is also affecting the local Layer 2 network. again a restart and connectivity is back.

Administrators Netduma Fraser Posted June 25, 2019 Administrators Share Posted June 25, 2019 Is there anything specific you're doing on the network when it occurs or could you be doing nothing and it still drops regardless on a regular basis?

Graham Posted June 25, 2019 Author Share Posted June 25, 2019 No nothing specific, sometimes playing playstation or web browsing and even when i am not doing anything my work email or teams will stop pulling data. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted June 25, 2019 Administrators Share Posted June 25, 2019 Just to confirm the IP for the router you have set to static is the WAN IP located in device manager correct? Not the LAN IP? Can you see on the BT hub if the R1 router gets downtime please? Link to comment Share on other sites More sharing options...
Graham Posted June 26, 2019 Author Share Posted June 26, 2019 Correct WAN is set to static. LAN is technically static as it's the GW IP. if by does it get downtime you mean the BT access control then no it doesn't Attached screen shots for both devices Link to comment Share on other sites More sharing options...
Netduma Alex Posted June 26, 2019 Share Posted June 26, 2019 Is that "always use this IP address" switch greyed out and unusable? I don't know why that would be set to "no" if it was on static anyway. It says there's no port forwarding although as you said, it's in the DMZ right? So that shouldn't matter.

Graham Posted June 26, 2019 Author Share Posted June 26, 2019 Always use this IP has the following text 'If enabled, the BT Smart Hub will always attempt to give the device the same IP address every time it connects.;' so DHCP related. Yes the R1 is in the DMZ Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted June 26, 2019 Administrators Share Posted June 26, 2019 I meant on the BT hub does it have a list of the devices connected and how long they've been connected or anything like that? If so does the hub register the router as going down/having a smaller uptime than other devices connected to it? Link to comment Share on other sites More sharing options...
