Hi everyone,
Hoping someone can help me.
The WiFi router was replaced today due to performance issues ( slow connections /latency when FireTV was in use ) But now I’m unable to connect to the “PiFi 5 Setup” network on my phone.
The RPi 5 is plugged in and connected by Ethernet cable to Eth1 port on the new router. All lights are on on both the RPi 5 and the Router.
Can someone help ?
Hi,
When you say you’re unable to connect, what exactly happens? For example, does it reject the password, or show a specific error?
One thing that can cause this is the port setting being on LAN while the Ethernet is plugged into the router’s WAN port (or vice versa).
What I’d try:
If you can tell me the exact error message and device (or a screenshot), I can be more precise.
This is what ChatGPt was saying …(courtesy of my colleague )
"that screenshot is from your router’s port‑forwarding page, but this is not related to why your PiFi AP shows “No Internet access”.
If your PiFi is only a router + VPN client, you do NOT need to open ports at all.
Your PiFi not having Internet is caused by the Pi not getting a proper LAN IP / default route via the new router, NOT by missing port forwarding.
Reinstalling the PiFi firmware will most likely solve the issue — but it’s the nuclear option, and you can fix this with 1–2 commands instead.
The Pi’s Ethernet interface name changed, so PiFi’s routing rules point to the wrong interface.
Examples:
Old router → Pi used eth0
New PiFi firmware → Pi uses enx…
PiFi NAT still forwarding to eth0 (which doesn’t exist)
Result → No upstream Internet → Android warns “No Internet access”
This is very common.
1 minute fix if you give me this output:
ip addr
ip route
Hi,
Thanks for reply.
I did several hours of trouble shooting with a friend on Friday afternoon/evening and managed to address the issue by doing a fresh install of the RPi FW image on the SD card. This seems to have fixed the problem. ( Although the WiFi speed seems much slower than with previous router )
(I put another post about an issue we had with flashing the FW image to SD card. )
Before the router was changed when I wanted to connect to PiFi 5 Set up on my phone I would just select it from the available WiFi networks listed.
It would automatically disconnect from the current one and connect to PiFi 5 Set Up and I would have internet access through that.
With the new router ( Mitra star WiFi 6 router ) the PiFi 5 Set up is still listed as an available WiFi in Networks options but when I click on it it says
" PiFi 5 Setup has no internet access "
The phone also was giving that same Android system message. See screen shot.
I use VPN for work so when I can’t connect my phone to PiFi and open PiFi app then I know I won’t be able to connect my laptop to it either.
Sorry I’m not too savvy on these things… I’m more if it ain’t broke don’t fix it …
Tap the top bar and select Yes (as in my screenshot). That allows your device to talk to the router even when there’s no internet access.
Then open the PiFi app. It’ll explain why you’re offline. Most commonly it’s because the port is set to WAN instead of LAN, and the app should guide you to switch it back and get online again.
Also, if the VPN is enabled while the internet drops, it can look like the device is “stuck” offline. It will not automatically fall back to unencrypted internet without you explicitly disconnecting in the app, as a safety feature.
