I was on Comcast's 75 down 10 up tier. A week ago i got Comcast's 1 gigabyte down and 35 up tier. When i was on the 75/10 i would consistently get 500 ms to 3200 ms bufferbloat and get a F grade on dslreports speedtest. Now that i have 1 gig service i get literally A+ and almost nil bufferbloat. Can some one explain why a lower tier gets and F grade and a higher tier get and A+ grade? I live in Jacksonville Florida. Any explanation or advice would really be appreciated. Thanks Gals and Guys:-)

[Connectivity] Internet Drops
For approximately 2 months now my internet with Comcast has been dropping at random times. Typically lasts 2 to 3 minutes. The link light is still on. Wi-Fi is still connected everything on the LAN side continues to work I can in any and all internal addresses. I can not be being anything beyond the modem.
Modem has been replaced
Cables and connectors have been replaced on the outside of the house all the way to the PED.
We have had 4 techs show and still no resolution.

[Business] Comcast Business / Static IP / Bridge Mode - what am I missing?
At a site I manage with Comcast Business I need a static IP but I also need the modem bridged. I use my own Cisco firewall and have VPNs to various other sites and cloud locations so nothing can work unless I have a static IP/bridged setup. Comcast support are however absolutely adamant that if I get a static IP the modem cannot be bridged but they can bridge it if I have a dynamic address.
I got this same answer from two different techs and from an escalated engineer at Comcast. At the moment I am setup with dynamic IP and bridged mode and everything is working however once their dynamic IP changes all my VPNs will fail so obviously not a long term solution.
So am I getting correct information from Comcast as it just does not seem right to me? I ask as I manage another site with Comcast business and it has a static and its modem is bridged and all works exactly as I need it to.
thank you!

[WiFi] xfinitywifi hotspot stopped working
I have xfinitywifi hotspot enabled on my Arris gateway, it's the only reason I pay $10/month to rent the modem from Comcast (we routinely have people in the house that want to use the internet). About a month ago, the hotspot suddenly stopped working. For a while, it would show 5 bars but you would connect, and it would only be 1-2 bars and barely stable. Then it stopped working entirely. It still broadcasts, shows 5 bars. On phones (Android or iPhone), you try to connect to it, it might say "connecting..." for a few seconds, but then it just goes to "saved" or even "disabled". On a Windows laptop, I try to connect, it spins for a few seconds and then pops up message "Windows was unable to connect to xfinitywifi".
I tried rebooting the modem (via unplugging, reset button, or having the Xfinity app send a restart signal). I tried disabling the hotspot in my account settings, waiting 24 hours, and re-enabling it again. I called support, they passed me to Tier 2 and Tier 3 support people who made no suggestions beyond "try disabling and re-enabling wireless adapter on your laptop and see if that fixes it".
So finally I thought it was a hardware issue with the Arris gateway. Last week I went to an Xfinity store and swapped it out for a new one. Hooked it up, lo and behold - xfinitywifi started working again! It worked for all of 2 days, on the 3rd day it started doing the same thing again, where it broadcasts but no device can actually connect to it.
Has anyone run into something like this?

[WiFi] XFINITY Hot Spots Reliability
I am getting totally confused over the performance of the hot spots and which they are. I have been using them for a very long time and in the last few months they hardly ever work. When I get on them I have no internet connectivity or else they constantly drop of (I am talking about staying in one place like an office, store, etc.
I am seeing some strange networks out there and none of them worked for me today while at my dentist office. On my iPhone &iPad they all showed 2 -3 bars on the antenna icon, but I had no connectivity when I chose them.
These are the networks I saw
xfinity (lower case)
XFINITY (upper case)
Cable WiFi ( it said sign into infinty network)
The last one was an acronym, something like TMCI and that also said sign into infinity network
I tried all 4 and either cit showed connected then fell off, or I would get a message saying no internet connection. Any idea what is going on or why I cannot get connectivity anymore? I live in the western suburbs of Chicago and have seen this in a 30 mile radius, even in Chicago.
Thanks

[Signals] Are these signal strengths okay? Modem had a 6db attenuator..
I think I got the MAC address etc. out - this is from Comcast on a Arris sb6121. Does the attenuator the installer left need to be reconnected or do we have decent signal strength for trouble-free operation?
Thanks

[Price] Large additional fees on bill
Comcast is well known for tacking on all sorts of ridiculous fees, but as I've never personally been a Comcast customer, I wasn't aware how bad it was. My grandparents just moved and received a quote over the phone for a good TV package with all the regular channels, plus Starz and Showtime. They are getting 200/10 internet service, as well as unlimited phone. While those internet speeds are certainly much more than they need, $130 didn't sound bad.
Now when I took a look at the bill, there is another $40 of various charges added on:
HD Digital Preferred 220+ Channels
Blast!® Internet Blast!® Internet
XFINITY Voice Unlimited US & Int'l Calling
$129.99
Universal Connectivity Charge - $0.87
Regulatory Recovery Fees - $1.87
Regional Sports Fee - $5.00
Broadcast TV Fee - $7.00
---
Customer Owned Equipment - Owned
DVR Service - $10.00
DTA Additional Outlet Svc (HD) - $5.99
---
TV Franchise Fee - $5.56
TV FCC Regulatory Fee - $0.09
TV Sales Tax - $1.44
Voice 911 Fee(s) - $1.65
Voice State Sales Tax - $0.76
Fees $40.23
Total $170.22
I even helped them purchase a modem a year ago so that they could cut down on some of the cost, but it's crazy to see firsthand just how badly Comcast deceives customers. In this case their actual bill is 32% higher than what they were quoted for. I assume this is completely normal for Comcast but I just wanted to check because I'm pretty surprised this is legal.

[Plan] Any Comcast Internet Essentials customers here?
I know that if you are, you might not want to admit it. Anyways, I have the service, and while it's mostly pretty stable, and I think not subject to a usage cap, it is slow. 12Mbit/sec down, 1Mbit/sec up.
Downloading a bunch of Linux ISOs, takes 2-3 hours for a group of them.
It was slow enough, that instead of cancelling my FIOS 50/50 plan, I boosted it to 75/75. (I have both.)
I am using an Asus AC68R router, flashed with Shibby Tomato firmware 140-MultiWAN. I use(d) the multi-Wan feature, to do weighted round-robin load-balancing between the connections, although now that I've boosted my speed on my FIOS connection, I may just use the Comcast connection for fail-over.

[Equip] It's dead, Jim.
Thunderstorm(s) passed through yesterday afternoon. Seems to have fried: the modem, the port on the router to/from the modem, and uplink/downlink ports on 2 downstream switches. Haven't noticed a problem yet with any plugged in devices, but haven't checked everything fully yet either. An interesting/weird path it took.
Yep, everything was "protected" from spikes/surges ...everything except for the cable coax line in.
Murphy's gonna getcha eventually, I guess.
