I believe what it does with CA depends on the supported combinations for the bands you have available.
Here we have B1 B3 B7 and B20 and no it will not do anything other than 2CA unless you restrict the band set. But I think that's just a not so mature firmware.

Anyway the EM20 performs better in ...

I am happy to tell you that, although not documented, the EM160 supports EM20 way of locking PCC to a cell id (and therefore a tower) using at+qnwlock=\"common/4g\",1,EARFCN,CELLID

I found a way to make it behave properly . Need to lock the explicit bands with AT+QNWPREFCFG="lte_band",1:3:7 then it will do 3CA or 4CA. If you leave it "free" it will stick to 2CA... buggy firmware, as usual from Quectel

First tests show that the EM160 is unable to perform more than 2CA.
Very likely there is a problem with the firmware. The EM20 goes back in service!

I wonder if the EM160 performs any better than the EM20.
I just received my EM160 yesterday so I'll replace the EM20 I have been using since couple months and run some tests.

correct but this is what quectel decideed it seems, EM20 will not receive firmware updates anymore and you can only buy it second hand now. I have one and is a decent modem, I am now waiting for the EM160 to arrive and compare the two.

EM20 will never be produced, replaced by EM160

again DO NOT buy it until they publish a working firmware for it

correct. unless you have a PCIE slot . PCIE is default.

I do have it working. Just a dog of a performer.

it works if you do the mods I explained above
but stay away because sierra refuses to publish the firmware for them, mine has clearly an early firmware and performs very badly

I shared above. You need to feed 1.8v to PCIE_DIS to enable USB, and 3v to VBUS_SENSE. If you don't it will be PCIE only.
This is clearly stated in the documentation. I did not do the modification myself because to solder such tiny terminals special equipment and skills are required, so I had a ...

I posted there already, I guess the guy you're talking about it's me :-)
I really would need someone with vendor access to the sierra wireless source site.
Or, patiently wait for them to post a firmware there which may mean one year waiting or so.
I have this gem of a modem and can't use it. I guess ...

I got it off aliexpress in China. Hence no "official" vendor, so to speak... but the unit is not an engineering sample, but a commercial unit. I find Sierra attitude quite harsh, I have a paid for production product and they refuse to provide an updated firmware for it.

It is installed in a ...

Just a follow up to my original question.
I confirm this modem requires that PCIE_DIS signal is connected to 1.8v and also the VBUS_SENSE needs to be high,
or it will not work in USB mode.

OTOH my unit has an outdated firmware and Sierra refuses to give me a more recent one. I am willing to pay a ...

Ok, so I got this EM9190 modem from aliexpress only to discover it defaults to PCIe mode and in order to have it switch to USB3 mode, a specific pin on the M.2 connector needs to be tied to a 1.8 volt signal.

What options do I have to make this modem visible by either ROOter or my windows machine ...

Its very similar hardware to the WG3526, and I've never seen this issue. I don't think it's a hardware limitation or kernel. It seems more of a bug somehow. I'll have to put an em20 into one of my routers and try it out.

I have two WG1608. In one of them I have the EM20, in the other there is a ...

Hi Didney, I have loaded it via chinese bootloader. But everything is working just fine, I don't see a reason to reload the firmware multiple times. This is probably a limitation in either the kernel or the hardware. And yes I tried MBIM mode and the message still appears. Please note that it ...

Im using the new em160r-gl. The new modem runs MBIM protocol not qmi.

What version of GoldenORB?

Yes, I posted there twice. The post was just ignored.

Guys. I am experiencing an issue with the setup discussed in this topic. It looks to me there is some limitation that makes this setup not 5G capable due to throughput issues. Please see my post here: https://wirelessjoint.com/viewtopic.php?f=9&t=1890 thanks.

I am running an EM20-G modem in QMI mode under GoldenOrb 2020-06-10 on a WG-1608 router.
Whenever there is high traffic on the modem (eg. during a speedtest) the router system log gets full of these error:

Sun Oct 4 18:01:56 2020 kern.warn kernel: [ 6659.340559] xhci-mtk 1e1c0000.xhci: ERROR ...

Hello, running GoldenORB 2020-06-10 on a WG1608.
I have installed an EM20-G and set it to work in ethernet (hostless) mode (USBNET 1)
Modem comes up fine, says wan1 is up but I cannot ping anything on Internet.

luci interface shows the modem as "present, not connected".
other than that, all the ...

Looks like EM20-G will never reach production stage. I heard that EM16-G has been replaced by EM160-G.

Can someone using the Quectel EM20-G modem tell me if the AT+QCAINFO command correctly returns carrier aggregation information?

Thanks in advance,
Rick

Guys, any way to have qmicli package installed on GoldenOrb 2020-06-10?
It looks like it's the only way to get CA info from RM500Q...

I have built this myself directly on the 1608.
Thanks to qmicli I have seen that the RM500Q is correctly aggregating (3CA for now) but the AT+QCAINFO is broken ...

Solved this as well
needed a modem reset (AT+CFUN=1,1 ) after changing usbnet to 2.

Thanks for the info guys - I already had the manual. I've looked through it pretty extensively to try to find an equivalent command to band lock. Have you guys been able to carrier aggregate with this modem? I have 100% signal strength, and another band available on my tower, yet carrier ...

So I got my WG1608 with a Quectel RM-500Q and flashed it with Goldenorb WG1608-GO2020-06-14.
The modem is correctly recognized, with IMEI and all, and so the SIM card, however the modem wouldn't connect and/or display any information about provider (Provider entry was just saying "Connecting ...

OK, recovered thanks to the chinese bootloader that appears at port 80 when you power up with reset button pressed.
Phew.

@optimusprime does your manual report the LTE CA combinations of RM500Q-GL? I can't find them anywhere.

Thanks
RIck

In fact I tried to email you through this place before posting this.
OK I'll wait for the countdown to reach zero...

Thanks Didney.

Looking to buy a fully working Quectel EM20 module.
PM me if you got one you want to sell.

Thanks!
Rick
