ContributionsMost RecentMost LikesSolutionsYears of stable/fast service - suddenly (4 days ago) about 1/10th the speed. Scottsdale, AZ - been a Cox customer for 10-years at this address. Always been Internet-only and always purchased the fastest plan available w/o incentives. For the last 3 years in my area been super happy with Gigablast (theGig-over-copper service). At the time they offered the speed upgrade and I selected it, I bought a new Arris SB8200 and Google Home mesh routers that I hard-wired all over the house. The combo has been fantastic. Problem... About 4 days ago, I noticed all the wired and wireless devices in the house buffering/timing out/etc and while they all eventually got back online (after about 24hrs of REALLY spotty connectivity), the speed has been garbage regardless of device or activity. I'd say about 10% of what it's been for years. I was wondering if anyone wouldn't mind eye-balling the log info from the Arris and see if something looked hugely suspect? Thank you for the help! (Sorry for the dump below - it seemed to be the way most people were sharing their logs...)

Ahhhh, ok got it. Thank you for the clarification. Ordered "Self Install" for Gigablast in an older neighborhood... is that ok? (for context: neighborhood is the Cactus Rd & Tatum Blvd area, by PV Mall) Been waiting for Gigablast for the last 2 years (although Cox has done an awesome job updating Ultimate all the way to 300mbps). Was just messing around on the website and noticed it was available as an upgrade option suddenly... nice! Selected it, chose "I have modem" (ordered a SB8200 from Amazon) and then was given a choice for: 1. Professional Install 2. Self install I chose Self Install because I'm comfortable with this stuff... but I was under the impression there needed to be a Fiber line install for Gigablast to work. I was told by a Cox tech last year (that was working in the neighborhood) that we wouldn't have Gigablast until all the standoffs in the neighborhood had been replaced and had fiber run to them. None of that has happened, all the stands in the yards are still the old ones, so I'm wondering if this is too good to be true? I don't mind having the pro install done if it's necessary, just want to understand what will happen here before I get too excited :) Thanks! SolvedRe: Introducing Cox Gigablast Ran into a technician today at lunch who told me to ask here to find out when Gig was going to roll out to 51st & Cactus area (by PV Mall)... Even a rough timeline (Month/Quarter) would be great. I'm perfectly willing to be a guinea pig if you need someone to test with :D
