G18 intermittent connection / rebooting on its own

New G18 I've had provisioned by xfinity appears to be repeatedly attempting a firmware update, it'll start with the solid amber “receiving power" light, then switch to a blinking amber “firmware update" light, then a blinking green “aquiring downstream / upstream signal” light and then a solid blue light which should be where it stays but it'll quickly return to the blinking amber stage and then repeats everything again. I've tried factory resetting it multiple times but it does not help. I've considered that maybe the upstream or downstream power levels or SNR are too high or low but they all seem within specI was on the phone with Xfinity support for an hour when I initially got it and they could not determine an issue on their end, after leaving it for a night it fixed itself for a couple days but has started doing it again after a power outage.

when I scan the QR code on the bottom of my new G20 it says “no usable data found”. Haven’t been able to connect to the internet however the G20 is showing as connected and secured in my settings.

G20 - Slow speed internet connection

Not tech savvy. Purchased a G20 at the recommendation of Best Buy for gaming. I have a 600mbps plan. I'm only getting 6 download and 1 upload after swapping my previous router-modem. Talked to ISP and they're not sure. Is there a setting I need to change? I didn't see one on the website for the modem-router. Any help would be appreciated. Thanks.

Inconsistent website access with G20

Hi all,I purchased a Surfboard G20 to utilize DOCSIS 3.1 from Xfinity, but it’s been nothing but headache so far. After connecting it and activating via the Xfinity App, I’m only able to access specific URLs. Notably, any Google domain (like Youtube or Gmail) as well as wikipedia. No other websites will load at all. I called Arris support and they said it was corrupted firmware and had me exchange the modem/router at the place I purchased it. I did so, and the replacement has the same exact behavior. I spent 4 hours on Xfinitys tech support chat, and they have no idea what the cause could be. I suspect it’s some kind of DNS problem, but I’m not savvy enough to be able to isolate it further. A windows 10, Linux, Android, and ChromeOS device all share this behavior so I’m absolutely sure it’s not specific to any device. If it helps, here’s the output of an ipconfig:Ethernet adapter Ethernet:

IMMEDIATE REFUND?!

I purchased the new G18 Docsis 3.1 Modem/Router Combination 48hrs ago. I downloaded Surboard Central on iphone. Connected brand new shielded Coaxial cable wire tightly with a pair of pliers, plugged in power to unit and ran Ethernet cable correctly. I had my ISP send a tech to my home to ensure my home pathway was clear from THEIR equipment signals. It is. After 27 unplug, plug back in sessions and 14 factory resets I still cannot get out into the internet. I ran 10 brand new Samsung Smart TV diagnostics and all come back saying unable to source internet. An Entire weekend with NO WIFI OR INTERNET!! I took it back to Walmart where I paid for it brand new, with tax almost $200usd I want a refund. This app Surfboard Central you refuse to genuinely make product installation “ plug n play” easy is costing you millions. I'm going to pay the extra $50 and get Netgears product. Then, I'm going to Trash the hell out of Arris on my social media to all my followers with a video to SHOW them the
