Until yesterday the term Mesh meant for me something placed into my abdomen to cure a hernia.
The Hub4 has had a few teething troubles for some people - they normally only supply them for customers on the 1GB package - but are also offering them to customers (like you) on lower speeds in areas where they would help connectivity. But TBH, if the Hub3 was fine, you have done the right thing to go back to it and use the boosters.
Mike, I and the others on here would recommend getting your own gear if that VM combo' wasnt doing the business. As it works for you, you should be fine when the Hub3 is back on. If not just come back here and let us know.
