I have a Ukrainian family staying in the annex to my property. There is no phone line and as it is the other side of a yard the broadband won't reach. I have a 4G EE router and contract. However it keeps crashing there are 2 school age daughters who are having video lessons at the same time. Am I asking too much of a 4g router? What would be the best options considering this won't be forever but they do need good connectivity.
