Ubiquiti NanoStation M5 Install Problems

Hello OM,
After many hours of searching this forum, reading the latest install instructions, Googling, searching & reading Ubiquiti's forums, I ready to pull out what hair I have left.
This is what I have done and where I am stuck:
1. Windows 7 machine with TFTP enabled as per instructions 
2. Using a dumb network switch in between my laptop and LAN port of POE
3. Plug in radio on the "Main" port and I using Command Prompt window, I can ping to http://192.168.1.20
4. I can use a browser (Chrome) and connect to http://192.168.1.20 then login to airOS and edit whatever parameters I wish
5. Unplug the network cable from the radio Main port
6. Holding the reset button down, plug the network cable back while waiting for the radio to have alternating LED flashes (about 20 seconds) to indicate radio is now in TFTP mode

FULL STOP
7. Can't ping to the radio "Destination host unreachable"
8. Tried a "Hail Mary" with  tftp -i 192.168.1.20 put aredn-3.19.3.0-ubnt-nano-m-factory.bin and says "Timeout occurred. Connect request failed."

9. Unplug the network cable from radio & computer for 30 seconds then plug back in
10.  I can now ping htp://192.168.1.20 and via a browser login to airOS, the factory image. NOT AREDN software.

What am I doing wrong?

Detailed Tftp command recheck needed

Hi Mike,

Assuming you are using a static address on the PC with the correct subnet, and have disconnected your wireless adapter.

I wrote up a detailed flashing protocol as a comment here in this forum:
https://www.arednmesh.org/comment/12452#comment-12452

Double check everything in the tftp command. Did you miss the -xw after the nano-m in the file name (assuming you are using an xw device)? It looks like you might have done that.

You must  type the full path to the folder containing the firmware like this (example using your desktop folder):
C:\Users\YourUserName>tftp -i 192.168.1.20 put C:\Users\YourUserName\Desktop\aredn-3.19.3.0-ubnt-nano-m-xw-factory.bin

You should get that file transferred message listing size and time.
Don't forget to reset PC back to DHCP after the flash succeeds.

Hope this helps. Keep trying

7. Can't ping to the radio "Destination host unreachable"

Maybe, when your PC is connected to the Nanostation running AirOS,
the Nanostation is a DHCP server and your PC is a DHCP client.
When the Nanostation is in 'TFTP' mode, it is neither a server nor a client.
It has a static IP address (192.168.1.20).
What is the IP address of your computer at the start of (7.)?
It needs to be 192.168.1.[2-19,21-254]
Hope this helps, Chuck

Still trying

Been busy with other stuff so finally had a bit of time. Spent another 2 hours & can't get this working. I can ping the radio when it's normally booted up and log into the airOS software with a browser and see everything. As soon as I go into TFTP mode, nothing, like the radio is gone & off the network. Can't ping it (192.168.1.20), I use arp -a and it's disappeared. Has Unquiti changed something in it's firmware to not allow tftp anymore or do I have a crappy radio?

Unreachable

Confirming your PC has a static IP of 192.168.1.5 / 255.255.255.0 the whole time? (or any number not .20) There is no DHCP service from the node in TFTP mode.

Confirmed Ian. It seems to

Confirmed Ian. It seems to just disappear when in TFTP mode. I am ready to do screenshots with a video. Maybe I got a poorly made radio? Maybe the Nanostation M5 is crap? I just want something with 45 degree direction antenna on 5 Ghz. I'm past the 15 day return to the store so if I can't get this working, I'm unsure what to do with it. Maybe go back to 2 meter packet :-(

As soon as I go into TFTP mode

As soon as I go into TFTP mode, nothing, like the radio is gone & off the network.
Yes, this is what is supposed to happen.
When in TFTP mode, there is no radio and no node.
Only a device waiting to be sent a binary file.
The device's IP address is 192.168.1.20.
If your workstation was previously given a DHCP address from the node while running AirOS, your workstation may no longer be able to route to its ethernet device.
You may need to create a static IP address in the range 192.168.1-19, 21-254 in your workstation.
Ensure that your workstation does not have another network device using 192.168.1.0/24.
You may need to unplug, replug your ethernet cable to get the workstation to reset.
Does your workstation have a Wi-Fi device using 192.168.1.0/24?

Hope this helps, Chuck

Hmm...

Don't go back to packet yet (no one is there any way!)

Try it without the switch? Windows Firewall off?

The unreachable instead of a ping timeout makes me thing something is up with windows/NIC or the network config after the TFTP mode change. Can you ping your laptop's own IP while the node is in TFTP mode and connected to the PC? Link light steady on the node? The MAC shouldn't be changing but try an arp -d and ping again.

The NSM M5 has been a workhorse for AREDN for a long time. It should be good to go once we get it flashed.

Update

For the record, I got it installed. Had to use a Linux laptop which I should have used from the start. I even installed it on our club's Ubiquiti NanoBridge M5 (different firmware of course) using Linux. Then installed Meshchat on both nodes so they can talk to each other. Now I'm trying to figure out how to have the node access the internet but that is a different issue as I must do more reading here and in the guides. Thanks for all your help. 73
