Improving Comcast modem signal


Our internet service is Xfinity/Comcast or Verizon. Currently I have Comcast service and use their modem because I had trouble with Netgear modem compatibility with Comcast. The problem is that the Comcast modem doesn’t allow LPS. I don’t know about the Verizon modem. So, for people with modem tweaking experience, any suggestions that will make a notable improvement?

The modem is connected via house Ethernet cable to EtherRegen in my listening room, which is connected to Lumin X1 streamer via fiber optic listening room.

Easy to use a non rented modem. Unlike fuzzytone’s experience everyone I know who has swapped rental modem out has never gone back. Maybe 10 people so just shows how a small sample size is problematic. 
 

Modem compatibility is easily verified on Comcast website or even Amazon. I currently own a Motorola MB8611 and am on Xfinity ie Comcast cable. Much easier to swap out and get working than before. All done online via their app. Oh, don’t buy a refurb as often those MAC addresses show as still in use and are a real pain to get authorized. 

I recently went through an install of xfinity/comcast.

They provided the xFi modem/router. It worked fine, but had a few drawbacks. First, $14 a month ($168 a year). Second, it’s WIFI coverage wasn’t very good. Third, their firmware does not let you override the router’s default DNS address, which for me, is a big problem as I use a piHole ad-blocker.

I guess another drawback is that it has an integral power supply, and you cannot substitute your own. FWIW, I am very skeptical that a LPS would make any difference whatsoever. Not trying to start a fight, but an LPS will not change the delivery of bits to their destination. If you’re one that is convinced that electronic noise from your network is a problem, you’ve already isolated your streamer/dac from that with the ReGen and fiber optic.

I returned the xFi and bought a Netgear modem and router (separates!). At first I wasn’t getting the speed with the new setup that I was previously, but phone call to to xfinity solved that. Their very competent and pleasant phone tech said that it was very common for customers to replace their modem/routers.

I am a Comcast Xfinity user as well. I did not know it is an option to substitute out their suppied cable modem and wifi router. I would love to get rid of that thing and not pay the monthly fee. The wifi is weak on that unit, and they told me I have theoir best one.  I often have to reset it, unplug and replug, at high traffic times.
