I definitely don't need more coverage... just the damn VoLTE activated so I can get calls and MMS at the same damn time. Like I said, it isn't a huge deal, just annoying that this is even a problem in the first place. They told me AR4 are out of stock and they have no idea when they'll be back, nor can they put me in touch with someone that knows. They said they just have to keep checking and see if it comes back in stock. Once again, I said that is nonsense, but what can I really do about it. For right now, the Pebble boosting the LTE, and using wifi calling, is working fine for my needs. Much better than the AR2.5 I was using which didn't work at all.
Yeah VoLTE took forever on Airave 4s, but it's definitely working now. Supposedly it was enabled months ago, but not necessarily for existing devices (only new ones). I had to factory reset mine to get it back in the queue, but after 2.5 weeks it got it. My Magic Box with wired backhaul, on the other hand, got it only 3 days after a factory reset. It seems that a lot of femtos setup before VoLTE launched never got put back in the queue (particularly femtos using WiFi or Ethernet backhaul), hence the necessary factory reset. I'm not sure if an Airave 4 would offer substantial coverage improvement over the Pebble, other than having CDMA as a fallback. If you need to cover a larger area, you can use both actually. They should handoff to one another with VoLTE, just keep them sufficiently far apart to minimize interference. And you'll probably have to tell Sprint it's for use at a different address, but they won't actually check where it's deployed. Sent from my Pixel 4 XL using Tapatalk
My router typically only gets rebooted for firmware updates or major functionality changes that I have implemented. Otherwise stays up for years. Last time it was down is when Hurricane Ike remnants hit Ohio in 2008 and caused week long power outages, which killed local internet in a few days (I have two ISPs, UPSes, generator). ISP's battery backups and generator use had improved considerably since that time.
Making changes appears to be the greatest reason for router instability. So put internet connections on a UPS, reboot after major changes, and otherwise enjoy.
