UDM Pro and Comcast

UDM Pro and Comcast

We have Comcast Xfinity cable internet. It is the only internet provider I can get. Because it is cable internet I am served my internet over a coaxial cable to an Arris modem, currently an under performing SBG7400AC2. This was a standard WiFi combo modem/router unit a long while ago. While it still functions it does not currently support the internet speeds we pay for. Nor the amount of wireless devices they have set upon it. The powers that be where I live refuse to upgrade, so they pay for speeds I cannot attain.

Well the router sucks as you would imagine, there is not much control over anything, and the wireless was severely lacking in performance. I have noticed that most household routers can only handle about 20 active clients before you start to really see an issue with speed and packet loss, pages timing out on you.

At work I occasionally deal with networking. I  was able to get my hands on and install and play with some Ubiquiti gear in the past few months. I ended up getting a Ubiquiti Universal Dream Machine Pro and a pair of UniFi Flex 5 port switches for myself to tinker with at my house. The special edition was a tad too expensive but I should have gotten that one in hind sight. The SE version adds all PoE ports (but only two PoE+ ports) and a 2.5GB port WAN1 instead of a 1GB port WAN1. Both have two 10GB SFP+ ports. AND, it seems the SE gets all the damn software updates first! What the fuck Ubiquiti??  I was able to talk the “management” into letting me use my UDM-Pro vs their current crappy Arris stuff and they agreed. So I installed a UDM-Pro and an U6-Lite access point. It was fantastic, the wireless coverage was now covering the entire house and the basement as well as it being capable of handling up to 300 devices. Fanfuckingtastic! The UDM-Pro also was achieving higher speeds (by about 200MB) with the modem in bridge mode rather than it handling the overhead of router as well. This worked great for a while, until I started to notice lots of high latency periods and moments of lack of connection.
