Nokia MBST issue. might be fixed with new SW.

it was ZY config issue. after I requested config from ISP it is ok now

nope. after some time it still fails to get anything to CA combo beside it's main frequency and N28.

Ok, seems like the main issue is when modem comes online on BC3 (1800Mhz) LTE as base frequency, it can't combine anything to CA anymore even in LTE mode, LTE-A does not go active. If I filter BC3 out of available list, it comes on BC1 and CA is working right. Seems like limitation or bug.

Nope. Not this. At the morning still same issue. Only BC3 and N28 locked and nothing comes in CA more.

Got it. It is kind of a misspeaking between NR7101 and Nokia BST. This modem located around 6 km away of BST and for some reason, when it comes up, it uses n78 (3500 mhz) 5G, but does not show it anywhere in statistics. I understood it when installed Huawei 5G modem next to it and it was showing it. So after 15 minutes BST…

I had nokia 5g modem connected to the same cell. it was ok before zy update released and became ok also. but why i deleted my previous post is it seems, like it is now more of my hardware issue after the zyxel modem. i will dig into it later deeper

....

Latest FW update V1.00(ABUV.7)C0 fixes this behaviour. From the release notes we can find the issue 9. [Internal Iusse #30757] [TR-369] Modify manual APN setting by SET message cause connection abnormal and connection unstable

Now i even locked my modem to one EPG so it would be less factors. Just randomly even when I get same IP address it can behave like on the picture or be stable. Restart - loosing, restart - not loosing. Kind of very random performance. Any way to debug?

upper graph is 5G and lower is Fiber. Same ISP, same IPTV stream provider, same channel, same time. Traffic is just blocked

my drop and error counters are 0, but today I understood the issue has nothing to do with burst. Traffic was ok today (only 23-36 mbps burst) but still these pauses appear and buffering starts.
