Constant disconnects

[Chup]

Good afternoon,

My R3 on firmware has been fine for months with DHCP at 10000 but recently it has been disconnecting near enough constantly for a few seconds then reconnecting, I've attached my router logs to this post to see if it gives anything away that could cause it.  It is on firmware V4.0.645 and two desktop PC's have Ethernet and one desktop is Wifi, the rest are a console, phones and a desktop PC that are on WIFI.

Have any settings or anything with the physical setup been changed prior to the issue occurring? Is every device disconnecting when this happens or specific ones? I can't see much to indicate why a disconnect is happening just that it is. What devices are connected to port 1 & 3 of the router? For WiFi devices, windows & Android/iPhones for the WiFi connection it's connected to there is a Private/Random MAC address option, please disable this, then reboot the router from the interface, wait 4 minutes and see if it continues please.

Hi Fraser,

The devices connected to port 1 & 3 are nothing in port 1 and port 3 is I think the xbox360 or PS3 I tend to swap the cable over depending on which console I decide to play. I'm not 100% sure what you mean, do I need to disable the Random MAC address option on the router or on the actual device(s) itself?. I'm just confused because it has been fine since when I installed the firmware months ago, it's only the past few days this has started.

I asked other people in the household and apparently the disconnects are only happening to me, I already have DCHP at 10000 and reserved my IP.

On the actual devices themselves, they're device specific settings so for example on the Windows PC that's connected to the WiFi, in the WiFi list when connected to the R3, click the 'i' top right of the connection and it will take you to the page you can disable Random Hardware Addresses. Same principle applies to the way you do it on a phone. The log may be reporting the ports reversed so could be port 1 = 4 and port 3 = 2, are those your PCs?

One is a desktop PC yes and the other is the ethernet for the PS3/Xbox360 that I swap around sometimes. I have changed nothing prior so these issues just randomly started a few days ago on and off. Thank you, I am in the process of changing the Random Hardware Address to Phone MAC or at least what that is the option on my oldish phone.

Okay keep us posted! Make sure to do the reboot as well, if it is the lease for some reason then that should prevent it happening for at least a week
