XR500 DHCP Lease renewal causes connection drop

[sno]

Hello, my lease renews every 24 hours, at which time I lose connection for about 30 seconds even though my ip never changes.  Is there a resolution for this issue?  My other Nighthawk R7000 router doesn't have this problem, lease renews without any connection loss.

Firmware versions I have tried:

XR500-V2.3.2.40.img

XR500-V2.3.2.56.img

XR500-V2.3.2.104-DumaOS3.0-Beta.img

Currently running: 2.3.2.40

Setting a static ip is not an option.

Thanks,

Jordan

Reporting back as I said I would, downgrading to firmware version 2.3.2.22 fixed my DHCP lease renewal connection drop issue for anyone that's having the same issue I recommend trying this.

Why can you not set a static IP, are you using a pure modem? The NG lead for the XR500 has provided a debug firmware and instructions on what to do should you encounter the issue to help them resolve it: https://community.netgear.com/t5/Nighthawk-Pro-Gaming-Routers/XR500-DHCP-issue/m-p/2023223/highlight...

The connection drop problem is with the WAN, not the LAN.  The drop happens when the dhcp lease renews with my ISP.  I still have connections with my NAS via LAN when this happens so it's a WAN issue.

My ISP doesn't allow me to set a static ip on the WAN without paying for a business line.

Plus, setting a static IP isn't a fix, It's a workaround.  I shouldn't have to do that.  Dropping the connection everytime the WAN lease is renewed is ludicrous.  

Thanks for the link to that thread, I'll try to provide some logs.  I've searched the forums and see threads going back two years for this problem.  They are just now trying to address this major issue?  /rolls eyes

If you're not using a pure modem but it is a modem/router then on the interface for that you can give the XR a static IP which would resolve the issue and you don't need to pay anything. I've been pushing for the issue to be resolved so I'm hopeful if they get some useful information they can get it sorted sooner.

It's a pure modem, I don't have the option to do that.

I could go to walmart and buy a $30 router, set a static ip to this piece of **bleep** $300 dollar router so it can function.

[Netduma-Fraser]

That's entirely up to you, it should help but I can't guarantee it. They are looking into it so I'm hopeful in the new year they'll be able to deploy a fix at some point provided they have enough data.

I read on another thread that everything below firmware 2.3.2.22 doesn't have this issue so giving 2.3.2.22 a try now, it's been three days and haven't had any connection drops when the dhcp lease is renewed.  I'll report back after week if it resolved the problem.  This is still not a fix though, I'm running older firmware that doesn't have vulnerability fixes.

Thanks for the feedback, Netgear are collecting data from users having the issue so hopefully that will be fixed shortly.

Thanks for the response, instead of looking at user data, they may want to look at what was changed from 2.3.2.22 to 2.3.2.32.  User data from alot of the later versions may not be so helpful due to the amount of changes made beyond that version. Whatever this bug is happened with the .32 update and propagated all the way up through beta.

.22 to .32 is an incremental update, it's probably something small that happened.

That's my 2 cents, thanks again.

[Netduma-Fraser]

Thank you for the input, I've passed that onto Tim as well.

Thanks, if you hear of a resolution I would appreciate a response to this thread.  I would like to get off of this firmware version at some point.

I appreciate you responding and escalating the issue.

What's this? I can't forward port 80?  No, remote management is 8443.

Port 80 is required for web browsing by all devices so it's likely UPnP even if it's not showing has opened this for devices. It is not a good idea to port forward 80 either as it could negatively impact other devices.
