Greenleaf Posted January 1, 2022 Share Posted January 1, 2022 Greetings! So I've been having random disconnects on my LAN internet connection, this only happens on my PC that is currently connected to my xr500 router but doesn't lose connection with devices connected via Wi-Fi. Does the DHCP lease change have anything to do with why it is losing connection? I was browsing around on this forum and saw that some users were changing settings from dynamic to static IP on the device. I am a total noob that all of this and was wondering how I add a static IP to my PC device? My current ISP is with AT&T, I am using their modem and have my xr500 connected via network cable. Hope to hear back from someone! Thanks in advance Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 1, 2022 Administrators Share Posted January 1, 2022 Hey, welcome to the forum! Based on the log and people with similar issues yes this is possible. On the LAN Settings page set the DHCP range to start at .50, then assign reserved IP addresses to devices between .2 & .49 (you can give them the IP they already have if they're within this range) so they're out of the DHCP range, apply, reboot from the interface, wait 2 minutes and see if that stops the disconnects.

Greenleaf Posted January 1, 2022 Author Share Posted January 1, 2022 So do I have to set a static IP with all the devices I have connected to the network? Or just the device that is having problems? Sorry I am a total noob and this is something new that I never tried to attempt before. Thanks. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 1, 2022 Administrators Share Posted January 1, 2022 You can do it with just the device that is having the issue, if it solves the problem and other devices then start having the issue you can do the same for them. No need to apologize! Link to comment Share on other sites More sharing options...
Greenleaf Posted January 1, 2022 Author Share Posted January 1, 2022 Ok so I am currently on this page on LAN set up. Again apologies for being the noob that I am but how do I go about doing this? I'm looking at this page and have no idea where to start? Link to comment Share on other sites More sharing options...
Greenleaf Posted January 1, 2022 Author Share Posted January 1, 2022 So I did change the DHCP range between .2 through .49. And selected apply. Looks like it did change. Hoping this is correct Update* I just noticed you mentioned to start the IP at .50. WHOOPS! So I changed it back from .2 through .254. if it get it to start at .50, what about all the other devices that are already assigned from .2 through .8? Will it have issues if I change the IP to start from .50? What do I add for the ending IP address? Do I leave it at .254? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 1, 2022 Administrators Share Posted January 1, 2022 So it would look like this: Starting IP Address: 10.0.0.50 then leave Ending IP Address at the default .254 Then make sure you add the reservation for the device in question, if some devices have IPs below .50 then you can assign them the same IP as well Link to comment Share on other sites More sharing options...
Greenleaf Posted January 1, 2022 Author Share Posted January 1, 2022 So I am currently on the address reservation list page in settings for the router. Do I assign the device in the range of the lower IP addresses, or do I assign an address starting at .50 or anything after that? As long as it stays under .254? Thanks in advance.

Administrators Netduma Fraser Posted January 1, 2022 Administrators Share Posted January 1, 2022 So you want to assign the IPs anywhere in the range between .2 and .50 To explain what is happening and why this should work DHCP basically handles giving out IPs to devices automatically. DHCP has a lease time where at the end of this time the IPs can change or be renewed, in this instance when that happens it may be causing your disconnect. If you give devices IPs within the DHCP range they still may renew and cause a disconnect. By assigning IPs outside of the DHCP range they will never try to be renewed and therefore hopefully will not experience a disconnect. Link to comment Share on other sites More sharing options...
Greenleaf Posted January 2, 2022 Author Share Posted January 2, 2022 So I did make my device its own reservation on the list, We'll see how this works out and will keep you updated on results. What if the devices on the network connected go with an IP address passed .50? For example 10.0.0.52. Update** I was playing WoW and it did it again! It still disconnected me, still able to log in after that but I am annoyed that it kicks me while in the middle of gaming. What else can I possibly do to eliminate and fix this problem? I'm starting to get very annoyed about this. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 2, 2022 Administrators Share Posted January 2, 2022 Any new devices connected will get an IP address automatically above .50, if they have a disconnect assign them an IP below .50. Ah, I believe I can see what the issue is, like clockwork every 5 minutes your public IP address seems to reconnect so it seems as though your ISP has a 5 minute lease time which seems absurd to me. For the most part it seems like the router can handle it (otherwise you'd disconnect every 5 minutes) but every so often it can't. I think what you would need to do is call the ISP and say that you're getting disconnects very frequently and that you've been advised by a networking technician that your public IP lease time appears to be every 5 minutes and increasing this will reduce the disconnects, 168hr lease time would put it at a week. Don't mention the XR at all as they may blame that - if they send a tech around then disconnect the XR and hide it. Greenleaf 1 Link to comment Share on other sites More sharing options...
Greenleaf Posted January 2, 2022 Author Share Posted January 2, 2022 Ok so they ran some diagnostics, they unfortunately can’t change the IP address but they did adjust some settings (according to the rep who was helping me) so let’s hope whatever they did, it worked. I will keep you updated to see what happens when I get back on my PC. Netduma Fraser 1 Link to comment Share on other sites More sharing options...
Greenleaf Posted January 2, 2022 Author Share Posted January 2, 2022 Well it looks liken whatever AT&T did, didn’t work at all. I have lost complete internet connection and now I’m assed out. They pretty much told me they reset the router and that I would have to connect all my devices to it again. So we ran some trouble shooting techniques and none of them worked. So now no internet till someone comes out on Wednesday and I am pissed off about this situation. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 2, 2022 Administrators Share Posted January 2, 2022 Did you say about the lease time and if so what did they say about it? You didn't need to have your IP address changed at all. Sorry to hear that, reset the router yourself and it will probably work - that's likely what the tech will do Link to comment Share on other sites More sharing options...
Greenleaf Posted January 2, 2022 Author Share Posted January 2, 2022 I did mention the lease time to them. They can’t change the IP address according to them. So they changed some settings but didn’t really tell me what they did. Resetting the modem for AT&T is what they did and didn’t work so now no internet for 2 days till someone comes out.

Administrators Netduma Fraser Posted January 2, 2022 Administrators Share Posted January 2, 2022 Okay the person you spoke to didn't understand what you were referring to then, they should have escalated your concern to a tier 2 support tech and in not doing so have caused a worse problem. Reboot or factory reset the modem you have an I'm sure that will get you back up and running. Link to comment Share on other sites More sharing options...
Greenleaf Posted January 2, 2022 Author Share Posted January 2, 2022 I explained it in detail and it sounded like they understood what I was talking about. whatever they did, it ruined the whole connection Are you talking about doing a factory reset on the AT&T modem? Or the xr500 router? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 2, 2022 Administrators Share Posted January 2, 2022 On the actual AT&T modem Link to comment Share on other sites More sharing options...
Greenleaf Posted January 3, 2022 Author Share Posted January 3, 2022 So I actually reset the gateway for the AT&T router/modem through the app and the Wi-Fi and LAN is working. But I don’t know if I connect my router back to it if I have to configure the settings on the router again so that it allows me to use the xr500 instead of the modem. I know there was settings that had to be configured on the AT&T router/modem in order to use the xr500. Link to comment Share on other sites More sharing options...

There shouldn't be a great deal of config required, do you know if you require PPPoE, VLAN or DHCP identifiers for you connection? Link to comment Share on other sites More sharing options...
Greenleaf Posted January 4, 2022 Author Share Posted January 4, 2022 So I am logged into the AT&T router/modem right now and in home network status all I see here is DHCPv4 netmask, DHCP server, DHCPv4 start address, etc. I am assuming DHCP identifiers, so yesterday I tested out (while playing CoD) to see if it did it on the xr500 and also on the Arris BGW210-700(AT&T router/modem)…. I am still encountering the same issue with disconnects on only my LAN connection. At this point I have no idea what else to do with this issue. I got in contact with AT&T to see why it is still doing that. They are suppose to call me back to see what is going on. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 4, 2022 Administrators Share Posted January 4, 2022 Put the XR WAN IP from the System Information page in the DMZ on the Arris and also set it as a static IP on the Arris and see if it works better then please Link to comment Share on other sites More sharing options...
Greenleaf Posted January 5, 2022 Author Share Posted January 5, 2022 When you talk about DMZ are you referring to IP pass through? Not sure on where to start to do this? Link to comment Share on other sites More sharing options...

Greenleaf Posted January 6, 2022 Author Share Posted January 6, 2022 I’ve done this and I’m still having these disconnection issues. At this point I’m just throwing in the towel, I bought a usb wifi adapter and hope that connecting via Wifi will work instead of using a LAN connection from the xr500 to my PC. I might just eventually buy a new router that is not Netgear. Link to comment Share on other sites More sharing options...
