Re: New ZBT WG1608 5G-ready router + GoldenOrb firmware

Re: New ZBT WG1608 5G-ready router + GoldenOrb firmware

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......

Re: Sierra EM9190 stuck in PCIE mode

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 OTOH my unit has an outdated firmware and Sierra refuses to give me a more recent one.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 fi...

Sierra EM9190 stuck in PCIE mode

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? C...

Re: Sierra EM9190 stuck in PCIE mode

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...

Re: Sierra EM9190 stuck in PCIE mode

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 frie...

Re: Quectel EM160 AT commands

Re: Quectel EM160 AT commands

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
