A few weeks back, xfinity came to my neighborhood to do ground work or something, the mail says "we'll be working to enhance and strengthen the network in your neighborhood" but after they finished, my internet drops for a few minutes about 3-4 times a day.
I've tried restarting router and modem and unplugging them for a few minutes, I've also tried restarting the router and modem from the website. My PC is hardwired/ethernet to it and still drops, along with the wifi.
Modem: Motorola SB6141
Router: TP-Link AC1750
Start with the modem's signal stats. Perhaps they already are, or they are close to being out of spec and intermittently they go completely of spec. Try getting them here http://192.168.100.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
Local signal / connectivity problems typically look like they are global, but 95% of the time they are at the individual's premises or the neighborhood infrastructure.
That said, if there is nothing that applies, then as stated, you'll need a tech out to investigate / correct the problem.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.
Good luck !
I had a tech come in, he checked around and mentioned that multiple neighborhoods in the area are having the same issue. Still having the same issue. I even tried disabling the wifi/router and leaving my PC plugged into the modem and it still went down (He suggested I purchase a new router). Now it's either a modem issue or xfinity's issue, but I lean towards him mentioning multiple times to me that multiple neighborhoods are having this issue.
