Subject: linksys wrt1900acs v2 boot problem
Date: Tue, 28 Sep 2021 22:01:40 +0300	[thread overview]
Message-ID: <CAAYUfvHJegq8Qwyqk5RdErkBkkYvj1HZXaOSodRZuOW8izs36A@mail.gmail.com> (raw)

Hi,
I have a problem with my linksys wrt1900acs.
My main question is this a hardware problem or software problem?
Is it possible to address?
I have started researching and have tried with "kwboot" under Windows VM -
Ubuntu 20 - Linux but I have a problem with usb serial connection. I have
tried several things but I understand that it isn't possible to start USB
to Serial on a Windows VM.
I will expect your response.
Thank you in advance.

All the best
Dilyan
