Thanks for the update. I am waiting for my replacement now. Definitely won't be upgrading firmware :)

thanks for your input and the "fix", digitalintruder! Unfortunately, it didn't work. Doing so, I was about to get 2.4 and 5-1 connected to a channel again but it won't Broadcast. The replacement will...

Anyone has any update on this? I am having the same problem, even with the replacement unit (i guess i made the mistake of upgrading the firmware on the replacement unit) :(

Anyone has any update to this. This is happening with my router too. I got a replacement from TP-LINK and the replacement has the same problem. thanks!
