Improving Comcast modem signal

Has anyone noticed a significant improvement with an LPS for the modem?

LPS?

12.00 GL eliminator

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.

It sounds like a dirty dozen laxative.

All the best,
