I understand very well before FTTH I had to struggle with a 6Mbps (yeah six) ADSL connexion for years… but it’s worth waiting 
My timeframe is september. As I’m not in a hurry I guess I will wait a little before buying the travel router and check the incoming products.
I will keep the RDP solution in mind but I don’t think I will be able to use it in the beginning. In fact my current job requires me to use a specific laptop for work with an already embedded VPN client on it to access my company network.
