Thanks for the info. It will help to diagnose connection problems. I don't know if it can automatically change bands, interesting if it does since there is rarely an advantage to do so since when something interferes with a band it usually wipes out all of them. Maybe since it has a 5ghz band there is more advantage.
But I think you hit on an obvious oversight in America routers usually only have 2.4 GHz band range while in other places they use a wider range. New routers are using more bands and there may be something the wireless cards are having and issue with.
Thanks for adding you solution I will have to investigate if it is the router or the wireless adapters that cause this
