So if I do a speed test using the tools on my C4000 - is it testing to my wife connected device or is it actually testing from the router in.  In other words I seem to have real consistency issues with my ISP - they want to blame my WiFi device.  If the tools on the c-4000 is testing from the c4000 up/down speeds then an extremely low connection \speed  is on their end and has nothing to do with distance to the router, walls etc. 

asking because the only laptop I hve that direct connects to the router takes 5 minutes to load and I am tired of constantly turning it on and connecting if using the tolls gives me the same answer instantly 

Thanks

Bob
