    You need this for Xfinity’s high upload speeds

    I recently upgraded to Xfinity’s gigabyte X2 internet package, which gives you 2000 mbps on download and up to 200 mbps on upload. To take advantage of the high speeds, I decided to upgrade both my modem and router. I purchased the TP-Link BE800 router and the Arris Surfboard S33. When I hooked everything up, my download speeds were capped around 1200 mbps and upload speed around 41 mbps. After reading multiple reviews online through Xfinity’s community forum, and other reviews, basically I found out I needed to upgrade to a modem to get the higher upload speed, so I purchased the Netgear CM3000, since the Arris S34 isn’t available yet. After hooking up the Netgear modem, my upload speed was still capped at 41 mbps, so I chatted with Xfinity technical support. During the chat, the Xfinity tech updated my firmware on my modem, and my download speed increased to 1500 mbps and my upload speed increased from 41 mbps to around 360 mbps! Basically, not only do you need this modem to get the high upload speed, you also need to have Xfinity update your modem on their end. All in all, it was definitely worth the extra time and money since i now can take full advantage of my high Internet speeds!

    200Mbps upload, a success!!

    This is what you need to access updated Xfinity internet speeds. I needed a modem that was approved for the 200 Mbps upload. I learned the hard way that even though a modem is capable, Xfinity has to approve it and they keep the list short. Whether this a way to force you to rent one of theirs…you decide. My current modem was a CM1100 that Xfinity no longer supported. I needed a modem that allowed link aggregation because the Orbi mesh router I have only has 1Gbps internet port and Ethernet so to access the 1.2Gbps I am paying for, I needed a second link. Surprised to find most modems do not have this. Keep in mind it has a 2.5Gbps internet port for those that have routers with the same. With the CM1100 and link aggregate I was getting 1250Mbps down and 40Mbps up. With the CM3000 and a single Ethernet, I am getting 900Mbps down and 220Mbps up. With link aggregate (two Ethernet setup) I am getting 1450Mbps down and 240 up. I took about 20 minutes to get it set up. I unplugged the old one and plugged in the new one to coax and power. After two rounds of letting the lights fully boot to solid, I used the Xfinity app to manually add the MAC address. There was a link below the internet modem status to add new equipment. I finally plugged in the Ethernet and powered up the router.
