I was advised to purchase an Archer AX3000 - AX50 model router - hoping to extend my range / speed as my security cameras keep dropping constantly - having tried linksys extenders to no avail. I have fibe 100 - but no actual fibe to the house - might be down the street.  download speed 100 upload is 10 by this mornings test. I have fibe tv so not sure if this would be affected with a connection.  Looking for some step by step for someone who is NOT schooled in these matters or language.  Has anyone had the pleasure of making this connection  or am i wasting my time.

Thanks in advance
