    Update 02/27/21 - It's been a little over a year since I bought this router and I thought it would be time to post a quick update. The router has been nearly flawless since I solved the initial READYSHARE issue. It's used probably 16 hours a day for work and school from home, streaming video from the connected external hard drive and more.Update 05/11/20 - A day after installing a Seagate 8TB external USB 3.0 drive to the C7800, it stopped being recognized on the PC via \\READYSHARE. I was still able to connect to the drive using VLC on my Samsung Note 9, but I was getting an SMB1 error on WIN10 which didn't make any sense as had been working just fine. After poking around online I found that the SMB1 protocol is out of date and using it opens you to vulnerabilities, I almost gave up and then decided to try to reset the router to its default configuration. In doing so, it upgraded my firmware from 3.01.40 to 3.01.43 and it also fixed the \\READYSHARE issue - go figure.ORIGINAL COMMENTS BELOW:So far, so good. I am getting strong WIFI on 2nd floor of house with the router located in basement. The 1st floor sub-flooring in our home is concrete and steel (1930's junior beam construction) and I had previously had issues getting any signal to 2nd floor even with WIFI extenders. My setup was painless as well as the Comcast installer called it in and had them activate it while he was onsite doing the cable install. I am connected to Comcast 100mbps service and am seeing slightly over 120mbps speeds on Speedtest via a Cat6 ethernet cable.. Roku and Tablo are flying along now. Will update as we get more time and use out of it.The 114mbps screen grab was done on my Samsung Note 9 using 5G wifi from the 2nd floor of our house. The router is in the basement and the signal has to go through steel I-beam and concrete subflooring on the 1st floor. We have Comcast 100mbps service, so it exceeds what we are paying for and the range is phenomenal. We used to need a wifi extender to get any signal bars on the 2nd floor of the house.

    The 114mbps screen grab was done on my Samsung Note 9 using 5G wifi from the 2nd floor of our house. The router is in the basement and the signal has to go through steel I-beam and concrete subflooring on the 1st floor. We have Comcast 100mbps service, so it exceeds what we are paying for and the range is phenomenal. We used to need a wifi extender to get any signal bars on the 2nd floor of the house.
