Hello i’m an happy owner of a Chateau 5g, i have a question about why when through terminal i put the command to update the module firmware i got the error: [admin@MikroTik] > /interface lte firmware-upgrade lte1
status: error: closing connection: <404 Not Found> 159.148.147.204:80 (5) (6)
Im wondering that the feature is not already implemented or am i missing something?
I have another “problem”, my unit don’t go higher than 2ca despite my bts is 4ca capable. I hope there isnt any firmware limitation or something else.
Thanks in advance for the answers.
I get the same error on my Chateau 5G:
This also occurred with the previous V7.1 beta 6 Router OS
According to Quectel, the latest firmware for it is RG502QEAAAR11A04M4G. My router has the A03 version.
on the quectel forum there is a way to update the firmware, but maybe you have to take out the modem.
I have the problem instead of going back from 7.1.rb6 to the original firmware 7.0.3 stable chateau is nowhere to be found.
does anybody know where to download the 7.03 firmware?
Same problem on my Chateau 5G. I think modem update is broken on it.
I also have Chateau LTE12 and modem update works OK on it.
Chateau 5G CA (Carrier Aggregation) is unknown. There is no publicly available list of possible CA combinations. I made support request for CA list but never got a reply from Mikrotik. My Chateau 5G can’t do 4CA B1+B3+B3+B20, although is specified as 5CA capable.
Lower is CA list for Chateau LTE12 (not applicable to Chateau 5G)

Mikrotik forum supplied info: EG12 modem supports max 6 spatial streams, so it works like this: for 1 CA single band 4x4 mimo = 4 streams, for 2 CA primary band 4x4 mimo + secondary 2x2 mimo = 6 streams, for 3 CA all 3 bands use 2x2 mimo = 6 streams.
mine has the 03 too. i asked for the 04 version from quectel and i got it, i took the module out and upgraded with m.2 to usb adapter..
yes this is what i did two days ago! now i have the 04 firmware revision.
thanks for sharing but that link is not working, i already searched for it but i think they deleted it
in regards to the firmware-update concerns, i think that the chateau 5g is too new and they will implement the module firmware update function in the near future

firmware: 11.04
The firmware upgrade command is now working on my Chateau 5G, at least for me:
Unfortunately, this new version does seem to want to connect in 3CA for me or very briefly. 
With the 11.03 version, it consistently connected in B20+B1+B3, using B20 as the primary band. With the 11.04 version, it connects in B20+B3. If I manually select B20+B1, it will connect in this combination, but not B20+B3+B1.
Even when it connects in B20+B1, it is getting a terrible B1 signal reading (-120dBm RSRP, -19dB RSRQ vs around -105dBm RSRP, -8dB RSRQ), like it’s getting the signal from another antenna port. I’ve ports A0 and A1 wired to the rear SMA ports, which run out to an outdoor pair of LPDA antennas.
I’ll try some testing later, but if I cannot get B20+B1+B3 back, I’ll end up going back to the Chateau LTE12. Most of my download speed comes from band 1 that it’s now having trouble with.
I think they uploaded the wrong version. The chateau 5g module is rg502q-ea, the update firmware listed in your screenshot is for the rg500q-ea that is another module. I think this is the wrong firmware
That’s annoying - I did not notice that. From checking what it installed, it appears to have installed the RG502… however, it certainly is behaving different to the previous version.
I can also confirm what I suspected about 3CA. I wired up ports A4 and A6 to the spare SMA ports using U.FL to SMA pigtails. From using the AT+CHAT cell monitor (RouterOS cell monitor is broken in V7.1RC1/2/3), when I attach another pair of antennas to these ports, the signal readings on band 1 improve, although about 10dB worse as these antennas are pointing through a wall (the main antenna is outside.)
When I monitor the cells, the signal strengths intermittently swap between bands 1 and 3, so one moment band 1 is strong and band 3 is weaker or vice versa. When I disconnect the additional antenna (that routes to modem ports A4+A6 inside), it drops the weaker band, i.e. which it was sourcing from these antenna ports.
Interestingly, the LTE status page just reports 2CA (B20+B3), but I know it’s connecting in 3CA as there is a huge difference in the speed between manually selecting bands B20+B3 (59Mbps down) and B20+B3+B1 (140Mbps down in following test). Without the additional antennas, I just get around 60-80Mbps depending whether it connects on band 1 or 3 with the main outdoor antenna (modem ports A0+A1).
I think there is stil few bugs on this chateau.. i have a tower with 4 bands but my chateau consistently use only b7+3 and sometimes aggregate b1 and b20 but they disappear in few seconds and then appear again.. i dont know why
hi how did you update? is the name of the file you got from quectel support is this “RG502QEAAAR11A04M4G_01.001.01.001”?

Hi, i updated the module with a pc using a usb to m.2 adapter
Chateau 5G modem RG502Q-EA supports CA_1A-3C-20A and CA_1A-3A-3A-20A combination in LTE mode.
I used the built-in firmware update commands as shown in the screenshot in post 12. Unfortunately, it was only after Salvot2990 mentioned that I noticed the wrong model # in the firmware version.
Hopefully whenever MikroTik puts correct firmware up that it will let me do an upgrade, especially with it reporting the installed firmware as RG502QEAAAR11A04M4G, unless the hosted firmware is correct but with the wrong title.
There was just typo in the firmware upgrade name - the firmware is correct.
