hi,

first time i see that, I wanted to update my build, with the new one on my 1900acs v2, the only thing i did, I plugged the router via lan in my pc (laptop) thats it, just plug in. and I lost internet..... i try to connect to my 5ghz or 2.4, nothing happens. My cell and other devices, no problem.

I reseted my network, I uninstalled my network card etc.

ok now, i can connect to my 2.4, but not on my 5...

do you have an idea?
thanks

This build has intermittent wifi radio startup issues. It's really a flip of the coin.

For now the solution is to manually set channels (don't use auto).

Other solutions are to restart the router, restart wifi interface, click apply or save/apply in wireless basic settings.

Once both radios are up and running you should be fine. Fingers crossed for the next build.

Reading many feedback, I thought this build was a better one. Am i right to undertand that this 42514 got wifi startup issue?

It's highly dependent on the router model and r42514 is affected to a much lesser degree than r42460 as most of it was resolved.

I got lucky on EA8500 with only one extra boot needed on r42460 to get it running and r42514 is flawless so far (for me).
