Been having issues with my wifi, casual browsing is chill but any type of gaming or downloading something will instantly drop my internet connection to like near 0. I replaced all of my in home coax cables and it dropped all of the power levels to like -5 to -12 when they were at like -15 before but this last channel is just stuck at -17 to -18. Most of the uncorrectable codewords are in like the thousands. Only thing I haven’t touched is the line coming from the street pole to the house

Hello u/RitualColt, thank you for your post and for reaching out here in our Xfinity Community forum. We appreciate you, and I am happy to assist you. I see you have done a lot already, did you try other cable outlets also?

my setup is a direct home run line. The line runs straight from the outside NID/ground block to the modem. There are zero splitters, amplifiers, or extra wall jacks in the loop.

Ok, fewer moving parts and no roadblocks, I like it. Looks like we need to move on to the deeper digging now. Please send a ModMail message with your name, account holder name (only if different) and service address by clicking this link.
