hi. I have a Three(3) mobile sim in my new MR600, not sure if it is operating as it should as upload and downloads sppeds seem a little low. Am I expecting to much for 4g mobile broadbsnd? Any tips?

I have just bought the mr600 ac1200 dual band router in the UK. Having trouble selecting and setting up smart plugs as they need 2.4ghz only. I csnt seem to rename one band id without the same name...
