I was surprised when the Xfinity tech showed up in the first 15 minutes of the two hour arrival window to address my lack of internet connectivity. He was a very nice young guy named Matt. I took him into my office to show him the cable modem. He stopped as he entered the room, impressed with everything that was going on in there. He said it was one of the coolest set ups he has seen. He asked if I was a streamer. I told him I sort of was. I gave him my EUC Army YouTube channel to peruse if he wanted to.
He said there was no signal coming into the house. He said the port on the block coming into the house was bad as well as the buried coax cable. He attached me to a different port, ran a temporary above ground cable and replaced the grounding block on the house as well. My modem showed an all is well white light afterward. Matt said a bury crew will be back in 3-5 days to install a new buried line inside of conduit.
When I went back inside the various wi-fi connected devices had returned to life however my computer which is hard wired did not connect to the internet. Upon investigation it appears that the USB 3.0 ethernet adapter I was using was damaged during the spike. I ran to Walmart to try to grab another one but all they had were USB wifi adapters so I grabbed one of those instead as well as a new 50 foot ethernet cable. I used the wifi adapter to get me back online but I ordered a new USB Ethernet adapter on Amazon. My plan is to replace the existing ethernet cable to get my hard wired connection reestablished which provides the most consistent speed. It felt good to be plugged back in.
