Can't find the missing piece to the puzzle

Another apparrent Comcast fiasco to report, I'm afraid. Laptop WIFI was doing 200+ consistently with Blast 200 Mbps and an XB3 Modem. Upgraded to 400Mbps and was instructed by Comcast to re-boot the modem to "install" the upgrade.  The only outcome of the re-boot was my WIFI speed instantly dropped to 7 Mbps on both my laptop and cellphone WIFI.  Comcast vigorously denied any cause/effect attributable to them. Next, told me I needed XB6. Next day, Tech brought the modem. My ethernet connection registered 400+ but WIFI still < 100 Mbps on the best of Speedtest. However, Tech showed me that he was getting a strong WIFI signal on HIS phone, so declared he has done his job, my WIFI card must be dead, my problem was not his problem, and left. Laptop being out of warranty by 6 weeks, Dell Support was no help. However, bought the laptop at Costco, so their Tech Support was available. Two separate Techs put in better than decent effort, lots of diagnostics which found nothing, helped me update all available Drivers including the latest WIFI,  and some blind shots in the Dark, but basically no significant change in my abysmal WIFI speed. before they gave up being out of ideas. This has now stumped a handful of people, some of whom actually appeared to have some tech skills. Anyone been down this road and/or have any idea what is going on, and how to fix it?  Any help at all would be appreciated. I am dead in the water and now tethered to an Ethernet cable draped along the wall and running under the door.

We've seen posts here that show that some Dell computers have a program that limits download speeds (like a form of a QoS feature). I'm not sure of its name but it may be called Smart-Byte. But if you can find it, remove it and see. YMMV. Good luck !

I dared to dream, to hope.....and after removing Smart Byte, having read so many threads where removing it had solved the problem for so many others........alas, but not for me. So I return to waiting for another kind soul to wander by and perhaps, if lucky,  to drop an alm in my cup to buy yet another chance to try again to end this torment.

Wi-fi is always variable, especially if you live in a higher density area, or have some kind of interference nearby.  Sometimes you can get relief by changing channels and/or changing bands. (Unfortunately, I think Xfinity has removed the ability to select channels on some/all of their gateways but you can replace it with your own equipment and save money in the long run anyway.)

 

I do anything of any importance on ethernet anyway so I'd be inclined to do a better install of the cable (or move the router or work station) than to fix the wi-fi.
