Re: EM160R Specify Transmit Band

I set it up the way you told me to, macuseri686. For anyone wondering how I found EARCFN 1 and PCI 1, it was like this:
I used the GUI to lock onto only the band I wanted to serve as my primary band, then ran the following command:
AT+QCFE="servingcell"
This displays the following information ...

Re: EM160R Specify Transmit Band


so, its not technically possible to specify which band gets used as the primary band (upload and download) vs the carrier aggregation bands (only download), but ive figured out a neat trick to make it work.

lock the modem to the primary band, but dont specify a second band to lock to. the modem ...

EM160R Specify Transmit Band

Hi, I have upgraded to a wg1608 with a EM160R-GL modem. The modem will CA on b2 and b12 or with b12 and b30. The download speeds are great but the upload goes very low because the modem is trying to upload on the higher frequency band. I want to specify that it needs to upload on b12. Is this ...

Re: AT&T shutoff of 3G February 2022 may affect you.

My mc400lp6 stopped working yesterday. The sim provider thinks it's due to the modem not being in the white list. I ordered a quectel em160r-gl from China that i hope will work with some tweaks.

Re: MC200LP-AT Carrier Reject / DHCP Failed

for clarity, it will not let me issue the AT!RESET command. I can't type it in fast enough before the modem resets itself

Re: MC200LP-AT Carrier Reject / DHCP Failed

Oh man, RP cables will throw you! You get it figured out now?

Yeah, I did. Thanks for the help.

That LMR-400 cable that threw me was an old one from a wifi antenna I had. I got some new coax and we're good now.

I am having another issue, though. When I bought my stuff, I thought I had line of ...

You may want to use the LP6.
I think you're right

Re: MC200LP-AT Carrier Reject / DHCP Failed

So I got a loaner mc400lp6 today.

It came with a couple of cradlepoint antennas. I plugged it into the cba750b with the same sim card and it works. Gives 82%RSSI with the cradlepoint antennas. The only thing is that the download speed is only ~1mbps according to speedtest. This is slower than the ...

Re: MC200LP-AT Carrier Reject / DHCP Failed

I tried the sim in another Hotspot device and it worked fine. It's an att enterprise data plan sim. I noticed the Hotspot device was on 3g so I tried forcing the mc200lp-at to connect in 3g only. Still carrier reject.

Re: MC200LP-AT Carrier Reject / DHCP Failed

So I tried a few more things:
I deleted the profile 16 apn by using AT command AT+CGDCONT=16,"","IPV4V6"
That didn't work.
Then I tried removing the external antenna and going to the base of a cell tower. Got good signal but still carrier reject.

When I do AT!GSTATUS? it lists tx power as 0 . I'm ...

MC200LP-AT Carrier Reject / DHCP Failed

Hi,

I just bought a MC200LP-AT, a CBA750B, and a 600-3800MHz LPDA Yagi Radome 9dBi-11dBi Cellular Directional Antenna from thewirelesshaven. I'm using a AT&T data sim in the modem. The sim provider has instructed me to leave the APN blank as they do not use an APN for their service. The modem ...
