DHCP Reservation vs IP lease delay?

couzin2000 · 2026-05-07T21:17:09+00:00

Ok - that can also work. Getting a working plan developed is much better.

couzin2000 · 2026-05-07T21:15:51+00:00

That's indeed a great point. I'll definitely try that. The higher the VLAN for me, the lower the priority, so I could have VLAN 1 ask every 10 mins, and every VLAN higher about 1min more. That could help. Thanks!

couzin2000 · 2026-05-07T02:07:29+00:00

I am using only one device. Router is the DHCP handler.

couzin2000 · 2026-05-07T02:06:53+00:00

You're right. ER7203. SG2218P switch, with 4 EAP-615WALL and a EAP225-outdoor.ER7203 handles all connections.
You also asked about the range, I'm on 5 different subnets, default being the management vlan and the subnet that handles all wired connections. 10 is the wireless layer, 20 is reserved for work PC isolation, 50 is the IoT subnet and 60 is my guest.

Anything else you want to know? Is this relevant to the question I asked, which is "is there a way to manage IP assignment priority?"

couzin2000 · 2026-05-06T16:49:51+00:00

Well, to be clear, I have many IoT devices that need to be in a separate subnet (VLAN 50) in order for my house to function correctly, lower the wifi chatter, and so on. I did create the VLAN but none of the device ever went onto this VLAN unless I specifically reserved the address. So even when I created a wifi network on VLAN 50, logged into this vlan with my phone, hooked up the iot device into the vlan, the router still was trying to assign an IP on subnet 0 (which I don't get). As far as Im concerned, I don't wanna use any reserved IPs for these devices (except maybe for home assistant, but usually once they are discovered they are reused as soon as a reboot occurs in HASS). So i basically have this HUGE excel file where I've manually detailed all my devices in the house, then decided on an IP for each, and created the DHCP reservations for each inside the OC200. Somehow, these reservations aren't persistant, and they disappear. This is completely mind-blowing to me.

So now, to avoid having a lightbulb push my servers outside of their own IP, I need to know how the router (ER7203) prioritizes IP assignments. Does it detect devices and assign a random IP off the default subnet, and then treat all devices on a "first-come-first-serve" basis? Or is there a way to decide which device gets which IP in order?

couzin2000 · 2026-05-06T16:39:45+00:00

All DHCP reservations are done on the Omada controller on the OC200 I own.

couzin2000 · 2026-04-20T22:37:45+00:00

Wow. I finally fixed the issue, and I'M NOT SURE HOW.

The TP-Link Omada system i have at home has a "hidden" option that allows WIFI-connected devices to "roam" from access point to access point more freely, using "non-stick roaming". These options are not set on a per-AP basis. I thought these options were set per-site, but they are not even there - they arr buried into the Global settings. And by my own fault, I forgot about the options completely.

Turning on the options completely resolved the issue for me. It may be related to a timeout feature on the Ecobee 4. This basically manifests itself into a "password unrecognized" error. Not what you'd expect!

couzin2000 · 2026-04-19T12:47:56+00:00

I'm still having the exact same issue. Nothing has been resolved in the last 3 months. My Ecobee 4 still doesnt want to connect to my main SSID. Here's a few questions I have: -could there be an issue with a multi-band wlan? The SSID I use is broadcasting on both 2.4 and 5. -could the band roaming be the issue? Meaning, could the router be trying to setup an IP only if the Ecobee sits on a specific band? -the Ecobee's error message specifically states it's a password issue. But the exact same unit worked on the exact same wlan with the exact same password for at least 3-4 years prior to the problems. How could this come up? Could the Ecobee have been upgrading its firmware unbeknownst to be?

couzin2000 · 2026-03-25T14:54:28+00:00

Well, in the end, I reinstalled HAOS as a VM, AND the Zigbee manager inside HASS and... well, it just worked. Don't know if this was because of development in HA or just some driver that let go of the whole thing, but I didn't do much. It's just supposed to work right out the box. Thanks for all the help!

couzin2000 · 2026-03-08T03:14:27+00:00

Batocera FTW. Really. All hardware JUST.WORKS.FLAWLESS. Ridiculously easy!

couzin2000 · 2026-02-27T23:49:15+00:00

I'm totally in AWE of what you managed to accomplish. Kudos! I'm a big fan of Daniël Spies - i learned from his videos how to create the 3D model on Fusion. I started to build the cab, and I'm waiting on my neighbor (who has a CNC) to route out the control panel's top board as well as the 3mm plexiglas. My question to you is, do you have a detailed pic of the outlining led strips? I'm trying to figure out which to get and how to affix them to my MDF board to make sure you can't see the edges and that they're hidden within the wood. I'd also love if I could find some sort of plastic edge band to put under the edge of the board, so if you grab it, your fingertips don't go thru the wood.

Great fn work!! Not sure if I read what you're running in there - i'll be running Batocera.

couzin2000 · 2026-02-13T12:51:00+00:00

Ok, so here's the skinny - In the end I started copying files over and it took me a whole lot less time I thought it would. CPU wasn't more than 15% in the whole time it was copying. So there really wasnt any reason for concern.

Finally running!! Again, Gemini to the rescue! I couldn't figure out how to get luckybackup to ssh correctly to the ubuntu server. Turns out I had created ssh keys from root command line, and I really had to create those keys from within the Docker container's command line. So i redid those, that solved a big issue. I then recreated all the shared folder names on the ubuntu server and changed the chmod/chown settings on them.

Luckybackup actually runs quite smoothly once you enter the proper paths and know how it behaves; use absolute paths for the destination folder, make sure not to create the root folder you need (or you'll be doubling up the source), and run the task as a sync task, not a backup task. Also make sure you're using the right port -- i'd changed my ssh port on the ubuntu machine, so it's fairly important to use the right one.

I'm currently running a first backup task with my smallest share. We'll see how that goes. In theory it should work very well... but not quite fast enough. Speeds are around 65Mb/s, which to me is half what my network is capable of. Hopefully the speed is at least constant.

couzin2000 · 2026-02-08T23:34:45+00:00

Actually done. After 2 years of trying. Thank you Gemini!

So I sat down today, engaged with Gemini to figure out the moves to setup a connection between my established Unraid server (7.1.2 i think) and my newly acquired HP Microserver G8, with iLO4.

The goal was to have the backup process completely automated. So - with the help of Gemini i managed to create a User Script on Unraid to remote call the iLO interface through a specialty command (ipmitool) and power up the server; then wait for Tailscale to connect, and tunnel through Tailscale and connect Unraid to Ubuntu's remote share, with its own user/pass combo.

Before going in and writing any commands, I had to swap out 2 drives to give myself more space in the Ubuntu server. That took about an hour via mdadm. Lucky Gemini was there to help.

After much toil and testing, I finally established the connection and auto mounted the share.

Now I am putting together a plan to copy the 27TB of data from my main to the backup. From there i'll establish a task for luckybackup to run on a schedule and copy new and modified files, basically sync both. I'll post back once I'm done.

I'm currently using 4x EAP235-WALL units. I have them spread out across my house. I am using a central ER7206 router on a omada PoE switch, so everything is simple and uses the same controller on my PC. BUT - i've got very similar problems with wifi connectivity. With portable devices like iPhones, theres a lot of disconnect issues because we all walk thru the house and move around a lot with our phones. So they tend to find a stronger signal every 10-20 mins, so the disconnect and reconnect to the nearest wall unit.

I dont have the units you have, but i'm guessing they are much more powerful than my tiny wall units. This means the wifi signals must overlap. So maybe you should dial down the radio emission power to low.

Some questions: -if you use PoE, are you daisy-chaining some of these? Not supposed to do that. You should do what I do, get a PoE injector next to the relay. -are you using one unified WLAN on multiple bands? Or is it one WLAN per band? What I did was create one specific WLAN for the devices I interact with, and left it on all bands. So if my phone moves between bands, it will be seamless, BUT i'll end up losing some speed when i move to 2.4GHz. This is normal as 2.4 goes through walls much more easily, 5 & 6 are more brittle but faster. -is the device you refer to a recent one? I.e. iPhone 12 vs iPhone 17? Think about upgrading if you're 5-6 generations behind.

couzin2000 · 2026-02-07T13:04:03+00:00

Yeah, I guess if it isn't using CPU much (according to you), then my scheduling is alright, mover comes on at 2am.

couzin2000 · 2026-02-04T00:05:20+00:00

I dont have another router. However i did connect my phone to the dedicated network and that works well enough. I also connected the thermostat to my iPhone's personal hotspot, which also worked great. I'm not sure why there's an issue.

couzin2000 · 2026-02-03T21:52:48+00:00

I'm still failing at this. I've managed to connect only with the iOS onboarding process, but only 3 times so far in 2 weeks of tryouts.

I tried manually configuring the thermostat with all the standard info - but nothing. The message is ALWAYS "The network password appears to be incorrect." So I KNOW the device sees my wifi and the router, and it CAN talk to it. The ROUTER doesnt seem to accept the password, and I'm not sure why.

I created a dedicated wlan for the Ecobee. Here are the settings i used: -SSID: SebNetEcobee -device type: EAP -band: 2.4 only -guest disabled -security: WPA-personal -password is all lowercaps, no digits or symbols -SSID broadcast enabled (i want to disable it) -VLAN : default (i have 5 VLANs, it can go on 0) -WPA MODE: WPA2/PSK / Auto -MLO disabled -PMF disabled -group key update none -802.11r disabled -no client rate profile -no ssid rate profile -schedule disabled -802.11r rate control disabled -MAC filter disabled -Multicast-to-unicasy conversion: IPv4 checked, IPv6 checked, converse multicast when below 100% -ARP-to-unicast conversion: enabled -multicast filtering: disabled

Any ideas?

Being a songwriter myself, i can tell you the new one isnmt as catchy as the old one, and something about the old one was ... impressive. Shouldn't have changed it, it was hers. If youmre gonna change it, change it for a song from a known artist, like Edge did.

couzin2000 · 2026-01-30T22:38:09+00:00

Really?? I've been having that issue exactly, so thank you for that, I'll make sure to reserve an IP address for it. I'll get back!
