I’ m having trouble with LS300 modems as a 4G gateway. Everything is working fine in our labs, in France (provider=Orange), but when used in the United Arab Emirates at our client factory (provider=Etisalat), modem does not respond to requests coming from the internet (no response to ping and no access to the computer connected to the modem). Strange thing is, a computer connected to the modem is able to access the internet, so 4G connexion is ok.
Is LS300 supposed to work in the Emirates ?
(Band frequencies are the same in France and UAE, apparently https://www.worldtimezone.com/gsm.html )
