# UniFi Event-Network Setup
|
||
|
||
## Goal
|
||
|
||
When the WAN link degrades during an event, bidder devices on the event Wi-Fi
|
||
should automatically fall back to the on-site server over the local LAN, with
|
||
no visible interruption beyond the connectivity banner turning yellow.
|
||
|
||
## Steps
|
||
|
||
### 1 – Note the server's LAN IP
|
||
|
||
Find the static or DHCP-reserved IP for the event server on your UniFi network
|
||
(e.g. `192.168.1.50`). Set a DHCP reservation so it never changes.
|
||
|
||
### 2 – Create a local DNS record
|
||
|
||
In **UniFi Network → Settings → Networks → DNS Records** (or **Local DNS** in
|
||
older firmware), add:
|
||
|
||
| Hostname | IP |
|
||
|-----------------------|----------------|
|
||
| `auction.event.lan` | `192.168.1.50` |
|
||
|
||
Set this same hostname in `.env`:
|
||
|
||
```
|
||
LOCAL_HOSTNAME=auction.event.lan
|
||
```
|
||
|
||
### 3 – Create a dedicated event SSID
|
||
|
||
- SSID name: e.g. `GalaAuction`
|
||
- Password: share on the event program or check-in desk
|
||
- VLAN: optional; keep on the same LAN as the server
|
||
- Band steering: enable for cleaner 5 GHz preference
|
||
|
||
### 4 – Test failover
|
||
|
||
1. Join `GalaAuction` on a test device.
|
||
2. Confirm `https://bid.example.org` loads normally (WAN path).
|
||
3. Disconnect the WAN cable or block WAN traffic in UniFi.
|
||
4. Confirm the connectivity banner turns yellow ("Local network – offline-capable").
|
||
5. Confirm bidding still works — bids are accepted via `auction.event.lan`.
|
||
|
||
### 5 – Battery backup
|
||
|
||
Plug the server, UniFi gateway, and all access points into a UPS. A 10-minute
|
||
runtime is enough to survive a generator switchover or brief power blip.
