I bought this unit the other day and wanted to use it in a LTE (4G) net in Germany in with o2 and/or E-Plus. The dongle is supporting LTE up to 100mbit, but when I connect it to the router, I just can select UMTS. This is what I have right now:
The only other option is:
Would appreciate any help with this, also if the other options are correct!
You can just choose umts for LTE. It doesn’t mean 3G.
Does the network connects?
Hello,
it seems youre right, the setting UMTS doenst seem to matter and the stick still connects via LTE. However I have the following issues now over the last days:
the router doesnt seem to auto reconnect, if the stick had a disconnect
the connection is broken it seems, after the stick switched from 4G to 3G and vice versa, and I have to reboot the router to get a working internet connection again
Hello? I found this on the OpenWRT wiki:
“<span style=“background-color: rgba(255, 255, 255, 0.8); font-family: Arial, sans-serif; font-size: 14px;”>Note: It seems multiwan isn’t perfectly suited for 3G modems in terms of stability. Modems don’t reconnect automatically by HealthMonitor. Also, after a manual modem restart, multiwan doesn’t use the newly reattached interface until it’s restarted.</span>”
is this true? So I bought the device for nothing? It was the only function I bought it actually for, to use it with my 3g/4g dongle.
If I leave the router+dongle on over night, the next day I have no internet connection anymore, and the routers doesnt auto-reconnect anymore. The only way to fix this is to reboot the router.
@mkdr, we modified mwan3 and it works with modem without problem.
Seems this is only a QMI bug and we can fix it. We fixed it in v2.264 for other routers but I need to compile and test for MT300N-V2.
You can use ttyUSB device if it works.
Thats weird… ttyUSB0 is working now, where it wasnt before, that was the reason why I switched to QMI. I will test with ttyUSB for a while if it is more stable. Nice to hear you fixed something with QMI though too for the next build. Here is my current config:
config interface ‘modem’
option peerdns ‘0’
option dns ‘8.8.8.8 8.8.4.4’
option country ‘country21’
option dialnum ‘*99#’
option metric ‘40’
option sp ‘isp1’
option apn ‘internet’
option service ‘umts’
option proto ‘3g’
option ifname ‘3g-modem’
option device ‘/dev/ttyUSB0’
Is option proto irrelevant? I am still confused because it is also a 4g/LTE stick, but is using the UMTS/3g net right now because of my bandwith limit is reached for this month. Maybe that was the reason ttyUSB is also working now, but wasnt before.
4G script is actually the same as 3G, so the proto doesn’t indicate it is 3G not 4G.
Ok I was too fast. ttyUSB isnt working anymore, and I dont know why. I just turned on the router and it has no internet connection. It just shows “modem connected” and “connecting to the internet” but nothing happens. I have changed nothing. Just turned off the router for a while and turned it on again. Rebooted the router now a few times, it is not working. logread says:
