I wasn’t originally very clear on how the BulletM5-HP is connected to the SURF as I am not familiar with it. I had trouble finding good online documentation on the BulletM5-HP so I was not sure if it was cabled in to the SURF’s WAN port or if it has its own AP (ie more than one radio) that you are connecting to with the SURF’s WiFi WAN. So pick through my response to see if anything helps but keep that in mind.
Also I think I got the WiFi WAN “standby state” backwards - it should be “stay connected” for better connectivity. Setting it to “disconnect” helps keep data usage down on a metered connection - but creates a slight delay when it has to reconnect. Either way kind of unrelated since the BulletM5-HP is probably connected to the SURF’s WAN port by ethernet cable.
Another thought… sometimes these devices get pissed off with disconnect reconnect cycles / logging into new AP’s repeatedly / playing with lots of settings / corrupt DHCP- try rebooting everything when that happens? I apologize in advance as you have probably already played that game. I’m an expert at rebooting.
If you can’t connect to the BulletM5-HP when it is not the active WiFi WAN (your original question) that may be a limitation of the SURF itself which may or may not be resolved with future firmware upgrades.
As per my previous suggestion you would have to power down priority 2 devices to force the SURF to “fail over” back to the BulletM5-HP / priority 1 (or manually set it by dragging and dropping the WiFi WAN tabs on the main dashboard).
You would want to log in to the SURF over ethernet to verify this is occurring. I never had much luck logging in to the SURF’s admin webpage wirelessly as it does not prefer that and you can lock yourself out (lol) if you mess up the settings forcing a reset and re uploading last known good configuration. Someday I will figure that out or not.
This probably won’t solve your problem but you could also try upgrading the firmware in the bullet. Make sure you do that over a solid connection or you could brick it.
I wasn’t able to find an owners manual for the BulletM5-HP (just quick start guides and datasheets) so that’s about as far as I got although the Ubiquiti site seems to have lots of README’s on usage etc…
Sidenote: It looks like the new dual frequency Bullet AC has “a separate Wi-Fi radio for fast and easy setup”:
….UNMS App The Bullet AC integrates a separate Wi-Fi radio for fast and easy setup using the Ubiquiti Network Management System (UNMS) app on your mobile device.
Accessing airOS via Wi-Fi The UNMS™ app provides instant accessibility to the airOS configuration interface and can be downloaded from the App Store® (iOS) or Google Play™ (Android). UNMS allows you to set up, configure, and manage your device, and offers various configuration options once you’re connected or logged in…
Then you could just log on via your smartphone during config / antenna pointing.
I don’t know if the BulletM5-HP broadcasts its own network that you could log into during setup /antenna pointing. It sounds like it might. The Bullet M2 does not but you can buy a “U-installer” (mini battery powered WiFi network) that performs this function aiding set up / antenna pointing. You shouldn’t really need this though as you should just be able to log into Bullet via the SURF wirelessly.
If your antenna is dual frequency it may be time to upgrade to the Bullet AC and keep the BulletM5-HP as a backup. Or just buy another antenna!
The spectrum analyzer software that comes with that thing looks sweet. I can’t believe how inexpensive the older Bullets are. Thanks for making me aware of these products. Only 330 more days 'til Christmas!
