Before you buy anything, try these tricks, you may be able to boost your signal without new equipment. I have tried the aluminum foil one and it does work. The placement of the router is also important (higher up from the floor, not in a corner, etc.) https://www.webafrica.co.za/blog/li...luminium foil to create,get it a curved shape.
If you rent equipment from Comcast you get royally ripped off on the monthly fee. Find their list of acceptable modems and buy your own IMO. https://www.xfinity.com/support/articles/list-of-approved-cable-modems
I was just responding to a post telling him to check for Comcast in his area. It doesn't matter which cable company it is, the rental fees allow them to recover the cost of the modem almost every year. I can't believe the regulatory bodies allow their equipment rental fees to be as high as they are. You should be able to find the approved modem list for any cable company with a basic search.
I know all about Comcast and their sky-high rental fees. Been with them more than 25 years from when the local company here in South Florida was Adelphia that Comcast took over. So I have had my own modem/router ever since. Anyway OP themselves never said anything about changing ISP so .... mute point.
Yeah I talked to Comcast last week in SF CA area.. They said sure bring your own modem, but the monthly fee goes up +$30. I notified the FTC. On the router, the key feature is MIMO, or multiple input multiple outputs. Older modems can only talk to one device at a time. Count up how many devices are on your network and plan accordingly. I do like the TP link brand. The mid to low end are great value, imo.
Look at most of his posts since 2008... In all seriousness, OP should do a simple speed test and latency test to see if his current setup is delivering. If it's not broke, don't fix it.
