Good morning everyone,
I’ve been having my internet drop randomly and more frequently now, I have been trying to figure out what’s causing this issues, I have checked my router and went through them to see if it was them, but it doesn’t seem like it. So now I’m checking my modem.
Here is my event log, sorry if its long. I’m just trying to figure out what all this means. I’m assuming this is what’s causing my internet to drop all of a sudden then come back?
My ISP is Xfinity, if there is anything else I can post that can help solve this issue please let me know.
Thank you,
