My new Archer C5400 suddenly behaved funny a week after the firmware has been upgraded. The 2.4G channel now runs in channel 64 while the one of the 5G channels runs in channel 1. I have now lost the 2nd 5G channel and the error is saying it is not available due to your region/country. Hard reset at least 10 times still no improvement.

I had a 3 hour chat with TP Link support. No solution.:mad:

Anyone seen this before?

You would better contact tplink technical support via mail not the chat.

Hi there, I used to have same issue and contact their email support and then they provided me a replacement. The replacement worked fine till now. I think it may be a fault unit.
