Hello,
I have recently upgraded my plan to 200Mbps. But I can get the max speed only upto 93Mbs. I have tried with multiple cable modem ( TPLink and Arris SB6190 ) both can support more than 200Mbs. I checked the speed my directly connecting the modem to my laptop. I had multiple calls with Comcast agents. Also one agent visited my home and told that issue is with modem. He showed me that he can get 200Mbps with comcast ( XFi DOCSIS 3.1 gateway )modem with the same laptop. I don't want to pay 15$ per month and rent the comcast modem.
But the TPLink modem was able to achieve 200Mbps earlier in my previous house ( different location ). Also it is weird that both TPlink and Arris shows the same issue. Both these modems are approved my Comcast. I am thinking of buying a new DOCSIS 3.1 modem now.
Note: I also tried with Netgear CM400 DOCSIS 3.1 modem juts now. Same issue us seen.
This is not a router/wifi/laptop issue issue. My laptop ( Macbook Pro 2019) is capable of getting giga bit speed. I have verified this though various experiments. I have a pfsense router with Unifi AP in home. But speed test is always performed by connecting laptop directly to cable modem via ethernet.
Some questions.
1. Do you think issue will get resolved with DOCSIS 3.1 modem. I don't have much hope to be frank.
2. Is it possible that Comcast is intentionally reducing the speed for user owned modem?
3. Any other solutions to this problem?
