Wireless Joint

Update on a somewhat old post...
So my Airmaster4000d stopped connecting completely. It says the sim is good, I still have an active LTE account, it sees the tower but does not register with it. I'm not sure what has gone wrong but it's very frustrating and I have no idea who to contact about it.

I ...

Replacement has now had a connection and device uptime of over 72 hours. I think the problem is solved, and that the previous device was just faulty. Some days it would disconnect and/or reboot 10-20+ times a day.

Speed and signal strength still vary quite a bit, but I think that has more to do ...

This device only has a POE power supply, no other jacks. I have tried 2 different POE injectors, one rated for .4A (the one included with the device) and one for .5A that I purchased separately, and neither fixed it.

I RMA'd the AirMaster and the replacement, so far, has only rebooted on its own ...

I replaced the POE injector and it seemed like it may have fixed it, but the stupid AirMaster just rebooted, so it's not fixed.

This sporadic rebooting and locking up is not acceptable. I think I need to RMA the thing and maybe get a replacement.

It behaves very strangely. Sometimes it reboots, sometimes it doesn't. Sometimes I can access its web interface, but when it malfunctions, I can't. It often drops the connection, and sometimes will reconnect on its own, and sometimes has to be rebooted. I'm worried that I have a bad AirMaster. I'll ...

Ok, for an update... I have enabled telnet on the AirMaster and will be checking the dmesg output after any outages. If you have one of these, enable telnet through the web config (management), enable local access, and log in to its IP (same as used for the web config, 192.168.0.1 in my case) with a ...

Nevermind, the POE injector does not handle the ethernet negotiation at all. It literally is a passthrough that adds power, so the interface disconnecting could be anything. It could be my router, the injector, or the LTE device. I tried removing just the POE side and lost the ethernet link on the ...

Also my router says the ethernet link went down... which would in fact suggest that it could be the POE injector messing up. I'm not sure if it functions as a bridge/switch or what, but the physical link is, I'm pretty sure, negotiated by the POE device.

Hopefully the new injector will get here ...

I ordered a replacement POE injector, but it won't show up for a few days.

It may be happening when it's warmer, I'm not sure exactly... it's happened twice today so far, once at about 5:30pm and at 6pm. At the 5:30 disconnect, it apparently rebooted since the uptime counter was reset. The 6pm ...

Same thing happens to me. I have no idea why it does that, and it'd be very nice if it didn't.

Not in a hot climate, and it is indoors. Temperatures maybe getting up to 75-80F the last few days. I only started using it a couple weeks ago, so I doubt it's SIM contact oxidation.

I purchased an AirMaster 4000D (technically in the "antennas" section of the site) for my Sprint service and 90% of the time it works flawlessly, with good signal, reliability and speed. However, roughly once a day, for an hour or two a day, it'll just start dropping the LTE link. Rebooting brings ...
