Hello - I purchased an Acer Iconia B1 tablet a couple of days ago and am having an Authentication problem when I try to connect to my wireless router. You've probably seen this problem before. What mystifies me is that I got online with no problem the other day when I was setting up. However, the tablet went into Sleep mode which disconnected me and I have not been able to get back online. I've made sure that it won't be going asleep ever again, but what do I do about this Authentication problem? Please note that I have very little technical knowledge. I have other devices hooked up to my router and they work with no problems. I've turned everything off and on. Powered off, turned off wifi on tablet, etc. Please speak very slowly and clearly so I can understand. I have no idea about codes. I have nobody here in my home who is capable of helping me with this. Thank you for your time.
