2nd RAX80 and all it does is drop the internet connection a dozen times a day.

What settings are you using on the router and what channels and is HT160 and MU-MIMO or Smar Connect enabled? I've been fortunate not face anything like that so far, could be multiple factors involved so if you give some more info, some us may be able to help you.

Also on a side note for future refrence, there have been quite a few people having issues with new AX routers regardless of what brand/company router you buy (they pretty much use the same base chipsets from either Broadcom or Qualcomm). When it comes to consumer networking gear, not the greatest idea to buy the latest and greatest as you will run into issues as the devices are stabalized over multiple firmware updates, especially when a whole new WiFi standard is involved. Some of these issues need to be resolved by chipset makers themselves who send updates to the actual router vendors. If you wan't reliability go for a router that's at least 6 months to better yet a year old, regardless of what brand you buy.
