If the wireless is still unstable then i would say to keep an eye on the link below for any new official firmware release, as it is most likely a firmware issue.

The beta firmware is something you can try if your wish. I do not have release notes on what the firmware includes, i normally ask customers to try the latest beta firmware as a test, as in most cases it helps with the issue they are having. I asked to keep any eye on the firmware download link as this is where future firmware and Release notes appear.

I am not aware of any issues with the Wireless on the 2860N series router. this is why is suggested alternative channels, Security mode etc, just as a troubleshooting step. So if you are still experiencing wireless issues, it may be an isolated issue with your unit.

If you belive the unit is not fit for purpose then you could contact your re seller to see if they will accept a return.

If it was an issue with one type of device (e.g. in the past some Apple stuff had problems with some WiFi routers, I think) I could understand it, but we're talking about every device everyone here has tried.

My suggestion at this point to the powers that be would be to increase the number of regular firmware beta testers. And maybe throw a carrot in - like whoever finds the most bugs in 12 months gets a prize, be it the latest router, or an amazon gift card, or similar.
