Since some weeks, I cannot nail it down exactly, our RED15W's are showing a strange behaviour. All of them are using the same type of UMTS stick, a Huawei 3272. But four of five do not communicate with their configured sticks anymore. To me it looks like their USB ports are somehow deaf. The network LED on the sticks are blinking, so they have power.
The sticks are working perfectly in an AVM Fritzbox 3272, they connect to the ISP and the connects are stable. When I use the Fritzbox as a router and connect a RED15W to it, the RED15W starts and builds a stable tunnel to the UTM. With a stick in the USB port the system LED goes red (Usual for UMTS connects), the router LED is green. Then it lasts about 20 to 30secs until they both start blinking for about 10 secs, get off and then start over again and again with the same result. I forced the RED's to load their config again, but that didn't make a difference.
WTF... RED15W works for itself, the stick too, but not together. And four of five are showing this, the 5th connects happily with its stick and has been working for years.
There are three AVM 3272 leftover and I can get three of our external stock buildings connected again, but having yet another device in the connect chain is not what I want.
Anybody having the same prob or am I the only unlucky fellow on the planet?
