Neither does AIS, I have checked my own router. Having said that 5G for most people unless you are downloading huge files or playing games on the internet is not going to give you very much. Yes it is faster but for most things you are talking a couple of seconds faster which is nothing to get upset about. If you really want to get the facility to handle 5G then some thing like NetGear would be a good choice but they are very expensive. For most commonly used internet facilities 5G will not give any significant saving. Only, as I said if you are downloading massive files or playing high end online games.
