Currently experiencing another full RF outage in less than a week. Had one last week which lasted around 30 minutes then everything came back online.
Today's has been going on again for almost 30 minutes with only one channel restored at this point. I use this as I work from home and is totally unacceptable!!!
Apparently it is a pretty large outage again as I have been on hold waiting for business support for over a half hours now.

[Plan] Extreme Pro Internet 400 Mbs - Side Discussion
Mod Note: This is for discussion about the rollout of this tier. Reports of actual receipt of the tier belongs here> https://www.dslreports.com/forum/r31481336-Speed-Report-Extreme-Pro-Internet-400-Mbps-Here ~sortofageek
I am trying to order the Extreme Pro (400 Mbs) pack as I have the old Extreme 150 and the Pro is cheaper than I am currently paying.
You can not order on the web site but have to call.
Finally get through to a human only to be told they don't do a 400Mbs internet for residential. The best they have is the Blast! 200.
I politely explain they go up to 2Gbs for home internet if you are willing to pay for it.
Anyone else ran into this issue, Or have an idea how to get around the human factor?

[WiFi] Xfinity Hotspot locations?
I've not much experience with the Xfinity Hotspots(the public ones). I have the Xfinity Hotspot App on my Tablet and Smart phone. I can see Hotspot locations all over and even have connected a few times. However I do not see any in my neighborhood nor in the apartment complex next to me.
Does Xfinity ever put their Public Hotspots in neighborhood streets? From what I can tell most seem to be located along major streets/thoroughfairs and more in business areas vs residential areas.
Do the Hotspots used in home Gateways show up on the Xfinity App?

[Equip] Emails says I need a new router - 100 MB Down - Arris TG6282G
I would consider myself semi-techie, currently have 100mb down/12mb up - Arris TG6282G (run in bridge mode/no router) and a ASUS AC-5300 running Merlin for last year - no issues.
I purposely went and got the Arris TG6282G after talking with regional line techs about the "best" modem for my situation last spring. So I get this email that they want to upgrade my equipment and when I click on it -- they show my modem and switching it to "modem and wireless gateway" ? Hey Comcast, can you be a little more specific ? Model number ?
My guess is that this is a "general email" and they have no idea that I have the latest ? But in case, I'm wrong..is there something better than Arris TG6282G ?
Also, I would buy my own and know what to buy but I need the stupid phone service, so that is out of the scenario here.
Thoughts ? Thanks !

As mentioned in this recent DSLR news item https://www.dslreports.com/shownews/Comcast-Prepares-For-Mid2017-Wireless-Service-Launch-139048 , Comcast is planning a mid-year launch of their wireless service.
Comcast announced today that they will be providing the details on this new service on Thursday:

Comcast sets Thursday meeting with investors to discuss wireless launch
By Daniel Frankel, FierceCable - April 3, 2017

:
Comcast confirmed plans to launch a wireless service combining the strengths of its vast Wi-Fi network and its MVNO deal with Verizon back in September. The launch has been slated for sometime later this year.
:
Last week, FierceWireless reported that Comcast is quietly partnering with Apple as it prepares to launch wireless service under the brand Xfinity Mobile: http://www.fiercewireless.com/wireless/comcast-quietly-taps-iphone-ahead-launch-xfinity-mobile
The cable giant’s name has been added to behind-the-scenes - but publicly available - code that lists carrier bundles for the iPhone. The list of carrier bundles is used by iTunes and iPhones to determine whether the iPhone’s SIM is supported by a service provider with whom Apple has an agreement, then provisions the phone accordingly.
The iPhone's latest list of carrier bundles includes "Verizon_Comcast_LTE_US," and mentions the service "Xfinity Mobile." A source pointed out the reference to FierceWireless, and a different source with knowledge of the matter confirmed that Comcast has indeed partnered with Apple ahead of the launch of Xfinity Mobile.

[DNS] Classless Reverse DNS Delegation with Comcast
Greetings,
I recently set up RFC2317 classless reverse DNS delegation of my Comcast-assigned static IP block and was pleased at how relatively straightforward it was to get working.
Because this was the first time I have ever actually set up RFC 2317 style delegation, I took some notes on the process and have expanded them into a bit of a tutorial describing what needs to be done on Comcast's side and the customer's side and thought I'd share them here in case they are helpful for anyone else who wants to set this up.
For those who don't already know, classless reverse DNS delegation allows you to update your own reverse DNS records without having to open a ticket with Comcast every time you need to make a change.
To keep things non-personally-identifying, these instructions assume that the Comcast-assigned customer IP range is 1.2.3.32/28 and that the customer is using the domain name "customer.net".
Comcast's instructions on how to contact them to set this up are located here: http://forums.businesshelp.comcast.com/t5/Domain-Names-Static-IP/IP-Scope-Delegation-to-Customer-Name-Server/td-p/25219
---
IPv4 Classless Reverse DNS Delegation Example (RFC 2317) for IP Address Range: 1.2.3.32/28
Terminology:
"Customer" - The person with the small static IP block who wants reverse DNS to work for those IPs
"ISP" - The customer's ISP (e.g. Comcast)
"Requester" - Someone on the Internet who wants to reverse-resolve one of Customer's IP addresses
"1.2.3.32/28" - The IP address range (1.2.3.32 through 1.2.3.47) the ISP has assigned for the Customer's use
"customer.net" - An example domain name, registered and used by Customer
"ns1.customer.net, ns2.customer.net" - Hostnames of the Customer's DNS servers. These need to have glue records of their IPv4 addresses registered with the domain name registrar.
The general idea:
Because of the way IPv4 reverse DNS works, when a customer has fewer than 256 IP addresses (a /24) assigned, the customer's ISP's DNS servers (as opposed to the customer's own DNS servers) will be asked for answers whenever a requester tries to reverse resolve the customer's IP addresses. Traditionally, this meant that such a customer could not update his or her reverse DNS records directly, and instead had to ask the staff at the ISP to make the changes every time a change needed to be made. Depending on how often the customer's reverse DNS records changed, this could be significantly annoying and time consuming for both the customer and ISP.
In order to give the customer direct control over reverse DNS for his or her IP addresses, the ISP can set up some records on their own DNS servers in a special format described in RFC 2317. The purpose of these records is to direct requesters wishing to reverse resolve the customer's IP addresses to the customer's own DNS servers. The customer, in turn, needs to set up the actual desired reverse DNS mappings (PTR records) on his or her DNS servers, again in the format described in RFC 2317. This process is generally referred to as "Classless IN-ADDR.ARPA Delegation" or "Classless IPv4 Reverse DNS Delegation", but Comcast seems to usually use the term "IP Scope Delegation to Customer Name Server".
Once this is set up, the customer can change/update his or her reverse DNS records directly, without having to involve anybody at the ISP.
Records needed on the ISP's DNS Servers:
In reverse (in-addr.arpa) domains, the octets are given in "backwards" order. So, the two NS records below tell the ISP's DNS servers to direct queries concerning "1 dot 2 dot 3 dot 32/28" to the customer's nameservers.
32/28.3.2.1.in-addr.arpa. NS ns1.customer.net.
32/28.3.2.1.in-addr.arpa. NS ns2.customer.net.
People tend to get used to reading these entries backwards and can get thrown for a loop thinking that 32/28 needs to be reversed to 28/32, but this is not the case. Unlike the '.' character, which separates levels in the DNS hierarchy, the '/' character is used only by convention (again, RFC 2317) and does not appear to hold any special syntactic meaning for the DNS server.
The NS records are only half the battle from the ISP's side. While they do direct queries concerning the 32/28.3.2.1.in-addr.arpa. domain to the customer's nameservers, nobody is ever going to attempt to resolve anything in that domain. If somebody on the Internet tries to reverse resolve, for instance, the customer's 1.2.3.40 IP address, what they will actually be looking up is 40.3.2.1.in-addr.arpa.
Because of this, the ISP needs to create a CNAME record, using the normal in-addr.arpa syntax, for each of the customer's individual IP addresses, pointing to that IP's subdomain in the delegated (32/28.3.2.1.in-addr.arpa.) zone, as follows:
32.3.2.1.in-addr.arpa. CNAME 32.32/28.3.2.1.in-addr.arpa.
33.3.2.1.in-addr.arpa. CNAME 33.32/28.3.2.1.in-addr.arpa.
34.3.2.1.in-addr.arpa. CNAME 34.32/28.3.2.1.in-addr.arpa.
35.3.2.1.in-addr.arpa. CNAME 35.32/28.3.2.1.in-addr.arpa.
36.3.2.1.in-addr.arpa. CNAME 36.32/28.3.2.1.in-addr.arpa.
37.3.2.1.in-addr.arpa. CNAME 37.32/28.3.2.1.in-addr.arpa.
38.3.2.1.in-addr.arpa. CNAME 38.32/28.3.2.1.in-addr.arpa.
39.3.2.1.in-addr.arpa. CNAME 39.32/28.3.2.1.in-addr.arpa.
40.3.2.1.in-addr.arpa. CNAME 40.32/28.3.2.1.in-addr.arpa.
41.3.2.1.in-addr.arpa. CNAME 41.32/28.3.2.1.in-addr.arpa.
42.3.2.1.in-addr.arpa. CNAME 42.32/28.3.2.1.in-addr.arpa.
43.3.2.1.in-addr.arpa. CNAME 43.32/28.3.2.1.in-addr.arpa.
44.3.2.1.in-addr.arpa. CNAME 44.32/28.3.2.1.in-addr.arpa.
45.3.2.1.in-addr.arpa. CNAME 45.32/28.3.2.1.in-addr.arpa.
46.3.2.1.in-addr.arpa. CNAME 46.32/28.3.2.1.in-addr.arpa.
47.3.2.1.in-addr.arpa. CNAME 47.32/28.3.2.1.in-addr.arpa.
With these records in place, here is (approximately) what happens when a requester tries to reverse-resolve the customer's IP 1.2.3.40:
1. Requester issues lookup request for 40.3.2.1.in-addr.arpa.
2. Requester is directed to ISP's DNS servers by DNS root servers
3. Requester asks ISP's DNS server to look up 40.3.2.1.in-addr.arpa.
4. ISP's DNS server, having a matching CNAME record for the request, tells requester "to find that out, you should look up 40.32/28.3.2.1.in-addr.arpa. instead"
5. Requester issues lookup request for 40.32/28.3.2.1.in-addr.arpa.
6. Requester is again directed to ISP's DNS servers by DNS root servers
7. Requester asks ISP's DNS server to look up 40.32/28.3.2.1.in-addr.arpa.
8. ISP's DNS server, having a matching NS record for the request, tells requester "to find that out, you should go ask ns1.customer.net or ns2.customer.net".
9. Requester issues lookup request for 40.32/28.3.2.1.in-addr.arpa. directly to the customer's nameservers, ns1.customer.net or ns2.customer.net
10. Customer's nameserver replies "no such domain exists", because we have not (yet) set up the relevant records on the customer's nameservers.
Records Needed on the Customer's DNS Servers:
The above records on the ISP's DNS servers direct requesters to the customer's own DNS servers when the requester tries to reverse-resolve the customer's IP addresses. To complete the process, we now need to set up the reverse zone on the customer's DNS servers as follows:
Name of zone: 32/28.3.2.1.in-addr.arpa.
Records:
32/28.3.2.1.in-addr.arpa. NS ns1.customer.net.
32/28.3.2.1.in-addr.arpa. NS ns2.customer.net.
32.32/28.3.2.1.in-addr.arpa. PTR desiredhostname1.customer.net.
33.32/28.3.2.1.in-addr.arpa. PTR desiredhostname2.customer.net.
34.32/28.3.2.1.in-addr.arpa. PTR desiredhostname3.customer.net.
35.32/28.3.2.1.in-addr.arpa. PTR desiredhostname4.customer.net.
36.32/28.3.2.1.in-addr.arpa. PTR desiredhostname5.customer.net.
37.32/28.3.2.1.in-addr.arpa. PTR desiredhostname6.customer.net.
38.32/28.3.2.1.in-addr.arpa. PTR desiredhostname7.customer.net.
39.32/28.3.2.1.in-addr.arpa. PTR desiredhostname8.customer.net.
40.32/28.3.2.1.in-addr.arpa. PTR desiredhostname9.customer.net.
41.32/28.3.2.1.in-addr.arpa. PTR desiredhostname10.customer.net.
42.32/28.3.2.1.in-addr.arpa. PTR desiredhostname11.customer.net.
43.32/28.3.2.1.in-addr.arpa. PTR desiredhostname12.customer.net.
44.32/28.3.2.1.in-addr.arpa. PTR desiredhostname13.customer.net.
45.32/28.3.2.1.in-addr.arpa. PTR desiredhostname14.customer.net.
46.32/28.3.2.1.in-addr.arpa. PTR desiredhostname15.customer.net.
47.32/28.3.2.1.in-addr.arpa. PTR desiredhostname16.customer.net.
[Note that in most filesystems, you cannot use the '/' character in the name of a file. So, if you were following the convention of naming your zone files the same as the zones they contain, you will need to substitute something else for the '/' in the zone file name. Do not make any substitution in the name of the actual zone, though.]
This completes the process. In step 9 above, when the requester issues a lookup request for 40.32/28.3.2.1.in-addr.arpa. to the customer's DNS server, the customer's DNS server will respond with the relevant PTR record; in this case, "desiredhostname9.customer.net.".

[Connectivity] MB8600 loses IPv4 connectivity ... IPv6 keeps working
Three days ago I upgraded from an Arris SB6183 to a Motorola MB8600. The SB8163 had been rock solid with my PFSense router/firewall setup. Since I made the switch I have had three random instances where I lost IPv4 connectivity, while IPv6 remained fully functional. When this happens, I am unable to pass any IPv4 traffic, including being unable to ping or log into the MB8600.
I tried pings from both my LAN as well as from the PFSense GUI and command line. I also captured packets on the PFSense WAN interface during the attempted pings. Packet capture shows ICMP packets leaving the interface, but no IPv4 ICMP response from the modem or CMTS. Normal IPv6 traffic is visible in the packet captures. Rebooting PFSense did not help. Rebooting the modem fixed the issue both times.
Modem signal levels look fine, including no corrected/uncorrected errors on the OFDM PLC channel and single digit corrected errors (and zero uncorrected) on a few of the QAM channels since the last modem restart last night. Modem hardware is v1.0, software 8600-6.1.1.19, and config file is d11_m_mb8600_blastpro_c01.cm. Lights on the modem: top/solid green, next 3/solid blue, bottom/flashing green
Has anyone seen similar issues? I have come across a few threads here on DSLReports as well as on the Xfinity forums of several people having similar issues with the Arris SB8200:
http://forums.xfinity.com/t5/Internet-Archive/Frequently-loosing-IPv4-while-IPv6-is-fine/td-p/2923874
https://www.dslreports.com/forum/r31767774-SB8200-losing-IPv4-connectivity-while-IPv6-works-fine
At least one other person is running PFSense as well, so I'm not entirely ruling out it being an odd compatibility issue between PFSense and the Broadcom-based D3.1 modems, but the return packets are not hitting the interface's IPv4 stack, let alone to even being seen by the firewall rules, and I never saw this issue with the SB6183 and PFSense. The NIC I am using in the PFSense box is an Intel quad port NIC, using the igb driver.
Is there any way to access the MB8600 interface via IPv6 so that I can check modem events when this happens? It seems like the modem events are cleared when I power-cycle the modem, so it makes it difficult to investigate the issue. Alternately, I have tried manually seting up a laptop for 192.168.100.99 and jacked into another port at the back of the modem (with my PFSense router still attached to port 1). When IPv4 is working, I can ping the modem at 192.168.100.1 and access the web interface. When IPv4 is not working, no ping response and no web interface access. This problem seems confined to the modem, not PFSense.
It appears I am on an Arris E6000 CMTS (Cadent MAC 00:01:5c). My LAN is set up in the 10.x.x.x RFC address space, so there should be no conflict with the 192.168.x.x address space used by the modem for the GUI. The WAN address handed out by the CMTS for IPv4 is in the 75.x.x.x address space.
Download speed tests are slightly slower for the MB8600 vs the SB6183 (consistently 290Mbps vs 300Mbps) [both tested via IPv4]. I grabbed the MB8600 on sale at Newegg last week while it was on sale in preparation to switch to a Gigabit plan. I'm not going to upgrade until this IPv4 stability issue is solved. I'm considering returning the MB8600 to Newegg, which is a shame because the sale price was really attractive.

[Equip] MB8600 Bonding
Anyone try to bond ports yet on their MB8600? I have mine plugged into a Microtik router using 2 lines and successfully got them bonded at 2Gbps max throughput using LACP as the bonding method... Now I don't have a tier that supports this yet but you can see via the interface statistics that data is flowing out both ports when you do multiple streams (LACP of course does stream aggregation... 1Gbps per stream max....) so I guess at least this modem is able to be bonded right now?

same time every day, signal loss for roughly 45-60min
I swear to god, this is driving me bananas. So in my last post I mentioned how they finally came out and replaced an entire section of line on the street running along the telephone poles, and either replaced or power balanced the amplifier. Since that time we still had issues where randomly the signal would completely cut out, we would lose all services and it would go in and out intermittently for a short while before coming back strong again.
We bitched at customer support about getting someone out here the other night, they said they would send a tech out to check the outside lines as we emphasized that NO ONE WOULD BE HOME DURING THE DAY. Well I did wind up coming home from work early the other day anyway and made it a point because I wanted to speak with whichever tech came out. No one showed up. Naturally.
To the point, what I am experiencing is that, for most of the day the signals are fine, great even. Power levels roughly between 8-9dBmv, SNR's in the high 30s low 40s across all 16 channels, correcteds and uncorrecteds are next to nothing.
RANDOMLY, and consistently these last few days between 2-4pm, power levels go completely hay wire, they will either drop off significantly, or spike to 14-15dBmv, SNR's drop below 30, into the mid 20s, and correcteds and uncorrecteds spike astronomically. The TV will go out, picture gets distorted and then the cable box shows it is unable to connect to X1, and the modem eventually loses its lock on all the channels.
It eventually stabilizes, power levels slowly drop back to where they normally sit, SNR's slowly begin to rise, and the connection comes back strong and is usually fine afterwards.
I haven't the FAINTEST clue as to what is causing this. Your thoughts? I am attaching pictures of what I managed to capture. Usually I know when its happening because I will either be working and the internet fails to respond, or the tv goes out, and then i log into the modem and check to see how the signals look and something is usually off. This time around I managed to capture it right after the initial spike in power levels.
