First I must say anybody at forum not doing testing like me (or not write it at forum) and I not have anyone who can confirm my problems. You use the same Band combination like me, this can be good key to doing checking on your site.
I have so many testing at few differ firmware then I must check my old reports to MikroTik support team, when I use original firmware v20 who is still latest, to give you information.
Check my command’s at: http://forum.mikrotik.com/t/v6-46-stable-is-released/135149/1
Firmware v20 in my opinion and in my ISP and band combination B3 & B20 have problems:
- At default settings, optional with own Band selection.
It’s slow recovering from offline. Weak re-searching the network signal (to do a registration in ISP).
Speed is not accumulate from be best speed from band’s. Ex. B3 give better DL but B20 give better upload then you not receive grate DL and UL (I not say as aggregation).
All this means fast recovery, fast registration in ISP, relative good speed are very very better at current internal Release Candidate and I hope this will be publish asap.
Some times I must do disable lte1 and enable lte1 interface to comeback internet. Using some watchdog/netwatch etc. should be used as standard in fw20 working at default setting’s. - In CellLock feature
who can force specific Band as primary band, you have reach/stuck offline and then: - CA Band is blank, he not connect at all or just in first minute disappear
- RSRQ = -19.5dB always freez with this number
- other signal parameters are freeze, every time with other value
- LED’s are off (in my situation and last signal)
- interface lte1 RX=0
- interface lte1 is still Running, still have Your ISP adress IP, active route etc.
- you are in offline, no internet.
- it’s not go to 3G/UMTS - modem freeze and not do anything
- SMS is not work any direction.
– - WorkARound: from fast to slow
[Try check firmware-upgrade | Try send SMS] start re-connection process > Set Cell Lock again or disable it > Re-Enable lte1 interface > Reset power-usb > Reboot. - Problem Replication: Change device position to wrong direction with CellLock still active, 2 ping timeout’s and you are in offline even if your device is in optimal position. This can be stuck in offline by minutes to 24h.
and one more.
- I not remember that was at fw20 or other beta fw but to reach ca-band again I must do:
reboot / usb power-reset / at+reset
after every setup CellLock / disable celllock / re-enable lte1 because those 3 operation work’s me like “switch off ca-band feature”.
Again, This is my opinion and I cannot give information that other person have the same problems.
You must check this by yourself.
Remember to check if the MikroTik share a new firmware, currently the v20 is latest and I use some other who is better and I hope this will be publicate in near future.
