Bullet M5 Accepts TFTP but won't boot.

I following the tftp firmware liad procedure here:

https://help.ubnt.com/hc/en-us/articles/204911324-airMAX-How-to-Reset-Your-Device-with-TFTP-Firmware...

 

The tftp load seems to work fine as you can see in this screen dump:

I wait for the network LED to start blinking then quit tftp and try to ping it.  It never responds to ping. 

 

I don't know what version firmware this had but I think it an XM. Do I have to load the exact version or will the latest XM firmware work?

 

TIA for any insight.

Re: Bullet M5 Accepts TFTP but won't boot.

A TFTP install seems to suggest you had some

major problem with the 'regular' install. If so, this

radio may have some internal issues--perhaps

with flash memory.

 

If a reset and regular install don't work and a couple

of TFTP tries don't either, I'd say it may be time to

replace this older 'legacy' radio.   Dave

Re: Bullet M5 Accepts TFTP but won't boot.

These are getting a bit old. Which produce would you recommend to replace our Bullet 5M's? We'd like to stay in the 5Ghz band and continue using our existing dish antennas.

Re: Bullet M5 Accepts TFTP but won't boot.

You don't describe your application, or the antennas.

But for point-to-point links, I can't advise Bullet--

either old or new ones. I used Bullets for my first

long link, but that was 10 years ago, and that

link never performed very well.   Dave

Re: Bullet M5 Accepts TFTP but won't boot.

Our current link is a 28 mile hop on 5Ghz. The Access Point has a 4 ft dish. There are 2 stations at the far end, both well within the beamwidth. One station has a 3 ft dish, the other a 2 ft panel. These are Worldwide units which we use in the ham band (yes I'm a licensed ham). We have the country code set to UK and the bandwidth set to 5Mhz to improve the S/N. Primary application is VoIP using the Asterisk PBX to pass traffic at 130 Kbps.
 
I noticed the new Worldwide Bullet spec lowest bandwidth is 10Mhz. Because our current bullets are set at 5Mhz our signal to noise ratio would increase if we used new Bullets. So those might not be the ideal replacement. Being hams we don't have much of a budget. Even so it would be desirable to improve the link.

Re: Bullet M5 Accepts TFTP but won't boot.

Virtually all modern point-to-point commercial gear I

know about is MIMO, and so requires a dual-polarized

feedhorn. I'm sure you know the advantages of MIMO.

 

All of Ubiquiti's current radios are dual-chain MIMO

[except for Bullet--which is now a minor product]. So

I don't have much product to suggest that you might

find acceptable within these limitations.

 

It's fairly easy to find big cheap dishes that aren't MIMO,

because they're commercial discards. But in some cases,

you could refit them with MIMO feedhorns. That would

open modern options for you--at some struggle of course.

 

Your application is incredibly minimal; a 28mi. link using

these big dishes and modern radios at 10MHz would likely

achieve 100Mbps or better--but that may be useless for you.

Cost isn't much higher than the modest Bullet.

 

So where does this take you?   Dave

I supose that means I'm looking for new equipment. Perhaps the next step up from the lowly Bullet. Any recommendations?

[ Edited ]

i don't know if it does; if my maximum data rate were under

1Mbps, I'd be trying to scrounge up some old Bullets. There

must be a couple out there somewhere.

 

if you go for new equipment, Rocket 5AC set to very narrow

channels, with Ubiquiti 34dBI MIMO dishes,would provide this

rate easily. You might even get away with PBE-5AC-620, at

about $200 each radio/antenna set; calculate the signals.

 

Of course, interference and obstructions can ruin the best plans.  Dave
