"I have “Blast” with my subscription with Comcast. My desk top computer yields 257 Mbps. My laptop thru WiFi is 40 feet away & yields 40 Mbps."

Is your desktop connected by ethernet cable to the cable modem? If so, the problem is your wi-fi, not your internet speed from Comcast. Connect your laptop to your cable modem with an ethernet cable. You will likely find the speed goes up. This type of speed drop with a wi-fi connection vs hardwired is not at all unusual, esp if your laptop is in another room with intervening walls.

Then you have to figure out what is wrong with your wi-fi router. If it is supplied by Comcast, then get back to them online. If it is not supplied by Comcast, then you should look online and find (on the Comcast web site) what compatible wi-fi routers are available and buy one and install it.

You just never know what you're going to learn on this forum. Warren, if my colleagues' suggestions don't work, please come back to us. While intellectually I know I could install a new router, I always prefer to have a pro do it. ComCast will resist this mightily. If you're not comfortable installing a new router, buy it from a place who will send a tech out to do it for you.

As Weilac said, this isn't an issue with your internet connection. It could be your notebook, router or home walls.

Is it even an issue? 40Mbps is more than enough for virtually any application other than web site hosting.

Wi-fi runs on 2.4 and 5 ghz. The 5 ghz is much faster. Your laptop may be connecting to the 2.4 ghz network. If you use an ethernet cable you bypass the wi-fi network. You should check out the network that your laptop supports.
If it supports the 5 ghz network you need to connect to that wi-fi network. Older laptops (and smartphones) usually connect only to the 2.4 ghz network.

Another potential solution is to get a wi-fi range extender (inexpensive compared to a new router). Google wi-fi range extender or look on Amazon.
This will extend the range of both networks and increase the connection speed.

This is absolutely correct, but I would add that the 5 ghz also has a shorter effective range. So if your laptop in several rooms away from your wireless router, the 2.4 ghz might actually get you a better connection.
