Modem upgrade needed?
Xfinity sent me an email telling me I need to upgrade my modem so that I can gain full advantage of download speed. I have the Performance Level internet from Xfinity, rated at 175Mbs. My current modem is a Motorola SB6121, specs say it can handle maximum of 195Mbs for downloads. When I do "speed tests", depending upon the server (I tested 7 servers), my download speeds range from 75 to 95.
Given the above, would a new modem achieve faster download speed ?
Thank you for your comments.

Yes, I'm streaming on a TV and running a cell phone network extender, have a tablet or two connected now/then.
Given what you see from my system hardware, I could replace my network card with a higher capacity card and then see if my existing modem gives me higher speeds? Then if not, replace the modem?
Really appreciate your guidance. Thanks.

Just installed Google Wi-Fi pods. 4 of them.
the desktop I did the speed tests on is hardwired to the mother pod.

Also FWIW, Comcast rates the 6121 for only up to 136 down;

Besides other issues, that thing is an old 4 channel dinosaur. Time to upgrade it !

I've got one of the new modems coming, arriving today I believe. Got the same email - "need new model to take advantage of new speeds" or something along those lines. I routinely get 200+ mbps d/l (hardwired, bridged to a RT-N66U) with my old voice modem, so not sure why it would be needed, except maybe for advance/new features of XFi/pods/etc? I don't really use those, but as has been stated in the threads my Voice modem is pretty old so replacing it isn't the worst idea I suppose. Plus the power plug falls out the back when a mouse farts so hoping the new modem has a more secure power cord :).

An update, new modem arrived, and the end of the story is yes it is faster, I moved from 200mbps to 350mbps on both Okala and Comcast speed tests... however as usual I don't expect either of those values translate into real world use numbers.
For the bad, typical of pretty much every Comcast change or upgrade, it never works out of the box. After watching the setup via xFi app fail numerous times, I call comcast, wait 45 for a call back, then spend another half hour on the phone with them activating the new modem. But, they get it activated and all is fine... or so I thought.
A bit later, I think oh yeah, the phone (since it's a voice modem), so check and of course I have no dial tone. So, another call to comcast, another half hour waiting for a call back - then 20 minutes with the "first level" of support only to find out she can't do the re-provision, so she transfers me to another dept, wait 20min on hold, then another 30 minutes getting my phone no. transferred from the old modem to the new one.
And now, top it all off, I go to xfinity/returns to print out a return label for the old modem, which is no longer associtated with my account (assumingly thanks to a overly helpful csa) so I am unable to print a return label for it, and will have to drive across town to the comcast store to return it since the one near me closed down...grrr.
To be fair, the CS agents were very nice, almost annoying too nice really. In the end everything is activated and working, but as is typical with Comcast it's was a painful process of several hours to get there. 😞
