GL-X3000 modem errors

I have an GL-X3000 using a Vodafone (Greece) SIM. It working very well: high throughput; connection stays up; reconnects quickly on the few occasions it needs to.

However the modem device is consistently reporting ~3 RX errors per second (see below). This is not affected by traffic (ie. does not go up with more traffic or drop when connection is idle).

Does this point to a “real” problem? If it’s OK to ignore the errors, can I prevent them being collected and/or reported?

Thanks
Sean
