may the higher bit error rate of Mobile Internet be a reason for @happybeing s issues with connecting to the network via his wireless router? 
could as well explain the strange things connected to bandwidth usage I’ve seen there:
ChatGpt sais:
Bit-Error-Rate of Mobile Internet typically 10^-3 to 10^-6
Land-Line 10^-9 to 10^-12
…didn’t do a proper research but I think that might be a hint … @joshuef … is our beloved network not precisely tolerant to bit-errors happening in the communication (especially when it comes in combination with lower available bandwidth)? …
