Hi,
I have just received the notification for modem upgrade. I’m a bit reluctant to upgrade via the interface so I would like to know what’s changing in the new RG501QEUAAR12A11M4G_04.200.04.200. Can’t find release notes anywhere (if on the Quectel side, they are well hidden).
Secondly, it is safe to upgrade via the interface ?
Thanks for supporting
Upgraded 30+ RUTX50’s through web interface already - not a single one failed.
Be brave and go for it.
People reporting much better speeds afterwards.
@TeWe …I’ve been brave and it worked, actually. Concerning speed, it looks the same or a bit improved but speed depends on so many factors that it is not even worth mentioning.
Thanks for supporting
Good to hear mate 
Yes, try to find the best physical location for your box to maximize signal strength.
Positioning and antenna adjustment are essential.
Happy weekend!
Had no issues upgrading modem via the server/interface, have noted no issues since upgrade. Unit was showing FW & Modem upgrades but I always manually upgrade FW, upgraded 08.1 from download then Modem on line, all appears well.
Same here - no issues whatsoever.
And yes, always FW first and then modem - with a few minutes in between.
How long did that modem upgrade take for you?
I did the upgrade via modem_updater and it took 13 hours!
Everything works great 
Did it via Web GUI and it took around 5 mins I guess
On 30+ RUTX50’s.
No issues at all.
However, in your case, Teltonika already said that this was definitely not normal…
Same for me
