Hi:
I’ve got two EC25-AF’s. I’ve been doing testing with just a USB adapter and antennas, and a “new” Visible (Verizon) SIM. EC25-AF works great when plugged into windows 11; it “just works”. Full connectivity, etc.
EC25-AF #2 when placed into the exact same test rig (same adapter, same SIM card, same PC, same location, etc), it obtains an IPv6 IP, but not an IPv4 address. Windows reports it “Connected” just like it does on #1, but I cannot get most things (like speedtest app) to work, but ping -6 ipv6.google.com does work just fine.
I performed this test because when I installed it in a microtik device, #1 would work, but #2 would say connected, but not work (I had IPv6 disabled).
So that’s two different devices, both cards show the same behavior. Is there some reset I need to do on card #2? It seems unlikely to be a hardware failure, but maybe it is??? I obtained both of these cards used.
Thanks!
