So far so good

I ordered this product to complement my Astound/RCN internet service. I pay for 1GBPS and after installing this the TP-Link Archer AXE7800 router, my speed tests are actually surpassing what I pay for. I will continue to monitor the performance for the next few weeks, but I am extremely satisfied right off the bat! It also has a very small foot print.
