dap007 Posted October 15, 2023 Share Posted October 15, 2023 Hi Guys, I have the netduma R2 router and have been getting multiple issues before. I updated to the newest firmware and it has not fixed the issues. I took off the R2 and ended up using the ISP's modem/router to provide wifi access to the household. I decided to retry the R2 and once again am getting random disconnects (have not been getting this with the ISP's modem). The R2 was running for a few hours, from a reset via the pinhole and went through the full setup, and disconnects again. I have attached the logs to see what needs to be done to finally fix these recurring issues. fyi, I have the DHCP Lease Time to 168 hrs as previously recommended. log-1697396269524.txt Link to comment Share on other sites More sharing options...
dap007 Posted October 15, 2023 Author Share Posted October 15, 2023 And just after posting, I got another internet disconnect. fyi using FIRMWARE: 3.3.280 see attached log filelog-1697397952679.txt Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted October 15, 2023 Administrators Share Posted October 15, 2023 It may seem counter intuitive but could you actually try setting the DHCP lease to 10 minutes and see if that resolves it please? Link to comment Share on other sites More sharing options...
dap007 Posted October 15, 2023 Author Share Posted October 15, 2023 Will the short lease time lead to disconnects and reconnects while connected on a server while gaming by chance? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted October 15, 2023 Administrators Share Posted October 15, 2023 From a report we've had no, for them it actually eliminated the disconnects altogether, try it without gaming first to see if you notice any disconnects Link to comment Share on other sites More sharing options...
dap007 Posted October 16, 2023 Author Share Posted October 16, 2023 So far so good but monitoring the situation. Link to comment Share on other sites More sharing options...

dap007 Posted October 16, 2023 Author Share Posted October 16, 2023 spoke too soon. So the internet is not always used "every second" so instances while watch netflix or reading a webpage for instance, you don't notice the disconnects, but when you happen to sync up the DHCP lease refresh, you notice the drops. I attached an updated log for your feedback. log-1697494631019.txt Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted October 16, 2023 Administrators Share Posted October 16, 2023 Worth a try! 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, reboot from the interface, wait 2 minutes and see if that stops the disconnects. If not, then disable DHCP entirely and see if it works. Link to comment Share on other sites More sharing options...
dap007 Posted October 17, 2023 Author Share Posted October 17, 2023 "assign reserved IP addresses to devices between .2 & .49 so they're out of the DHCP range" Just to clarify, and it may be a dumb question, but by assigning reserved IP between .2 and .49, you mean for the devices connected to the router? For Example, Laptop .2, Cellphone1 .3, Cellphone2 .4, TV, .5 and so on? -------------------------------------------------------------------------------------------------------------------- Also 2nd issue, this was happening before and was the cause of me taking off the router for a few months because it was pissing me off. When the disconnects happen, it modifies the wifi ranges for both 2.4GHz and 5GHz. For 2.4G it only allows channels 1-11 and 12, 13 are missing from the drop down selection. For 5G, it only allows 36-48, all other channels are missing. The biggest issue is that I am in a fairly dense wifi area, and a lot of the neighbouring routers are in the lower bands while the higher bands are clear but when I select those, for instance 153 and the router "disconnects", it drops all connections and I have to reboot the router to connect any device. I attached a screenshot for reference. Link to comment Share on other sites More sharing options...

dap007 Posted October 17, 2023 Author Share Posted October 17, 2023 Should I leave the DHCP time to 10 mins?

Administrators Netduma Fraser Posted October 18, 2023 Administrators Share Posted October 18, 2023 You can leave it on 10 minutes for the moment. The WiFi losing channels does happen after a reboot unfortunately, best to set it to automatic and then it will choose the least congested channels, we'll get it sorted.
