Slow internet speed
I'm hoping someone can help me out. I have 200 mbs blast but running the xfinity speed test I get 90 mbs max. The first tech that came to the house said that there was water in the line to the street. When that didn't fix it, the second tech brought a box that connected to my Motorola modem/router output port which showed 250 mbs. When I connect the same line to my computer and ran Xfinity speed test it shows 90 mbs. The tech's response is "your computer is old" (new 1 month ago). Same cable connected to his diagnostic box or computer shows either 250 mbs or 90 mbs.
Why would the Comcast diagnostic tool read 250 mbs on a modem/router output port when the same cable connected to the computer and running Xfinity speed test shows 90 mbs?
