This year has be the worse , Comcast doesnt care if your service is down. They just blame it on you. 4 trips and 2 techs to fix 2 boxes and 2 tivo out , the day they went to full encryption. No offers for compensation. They are worse then bell in the 80s . they just dont care about you as a customer, if fios was available i would just switch.

I don't like special deals for new customers when there is little effort to keep existing customers. Which is more important, continued support of existing customers or new customers which may not stay?

Tech support which required a home visit on the last couple of calls was puzzling. Each rearranged the splitters saying whomever did the connections did them wrong. Apparently each tech has their own opinion.

Purchased my own data modem to eliminate the modem rental charge only to find that I had been misinformed by the local office. I still get charged for a voice modem. Shouldn't the voice modem be part of the phone service?

Not much has changed in three years. Speeds have gotten better, customer support for problems still consists of "unplug your modem for two minutes."

Upgraded to the X1 system. Every few days the secondary box will hang and be non-responsive to the remote. Only solution is to power cycle the box. The satellite boxes are slow in responding to the remote. Really don't like that the boxes become completely non-functional if some server for Comcast goes down. Cannot change channels or watched stored content. That is a really bad design.

If the comcast/twc

merger goes thru the consumer will lose any hope of fair rates and competition. I live in a semi-rural area and I would have to pay $30 more for what they pay less then 25 miles away. WE NEED MORE COMP NOT LESS!!

I have the Blast service. 105 Mbps down, and 20 up. »www.comcast.com/internet-service.html shows an "Extreme 150" service, which in the past I would have been automatically ungraded to. 7 calls to Comcast, of which 5 did not speak enough English to get started, one to "Sales," one to someone in India, produced no help at all. The woman in India did say I have the "Extreme 150" service, and had a tech sent out. The tech swapped modems, for a different brand, with the result that I not only have no higher speed, but seem to have lost IPv6 compatibility. Three days ago the 20 Mbps upload speed dropped to 10 Mbps, and is still there. For a month I had the 150 Mbps rate - using speedtest.comcast.net for testing - but then it went away. Apparently someone is constantly testing speeds and other issues. So while the connection itself is reliable, I don't know from day to day what data rates I'll have. Oh yes, I continue to pay for 105 Mbps down, and 20 Mbps up - that much is as dependable as the sun going down at night and coming up in the morning. I'm also told now that after the merger with TW, Comcast will dump the Great Lakes region, and we will get Charter instead. It never ends.

Comcast XFINITY Performance cable Internet (25/5 Mbps) - $39.99/mo. for 12 mos. special.

Order and install very smooth.

Have recently experienced severe, consistent performance slowdowns after 3-4 mos. of use. I've been experiencing a consistent effective transfer speed that is 80% less than the advertised speed at all times of day, all days of week.

I moved into a newly built home and Comcast would not service it even though our neighbors had Comcast service. It took me over 3 weeks several tickets with their help desk before I gave up and emailed corporate. They finally rolled a truck to determine if they could service my house; they determined that they could. My install was set for 3 weeks from that date.

On install day the tech showed up on time and installed the new Xfinity cable box and a cable modem. This worked fine for a couple of weeks but then my internet went out and I had to have Comcast come back out. They replaced the modem and service was restored. This modem lasted for 2 months and then died. I opted to buy my own modem at Best Buy (Motorola SB6121).

The cable service is spotty. The box needs to be rebooted every other day and it is slow as can be. I like the new menu and search options but the lack of reminders is a bummer. Not everyone wants a DVR.

All in all the service is OK. I'm a former Comcast employee and expected more from the company. However this time around I felt the burn that most consumers feel.

Good "Lot of Content and many options for viewing"
Bad "X1 Buggy OS, many reboots per day, Typical Cable HSI bandwidth Lies!"
Overall "Not worth the cost for half-a** service."

5 TV's, 105Mbps HSI, RG-6QS cable, 10/1000 Giganet, Cat 5E & Cat 6 network cable, Dual radio 802.11 *(2.4 & 5GB) N wireless.
House Construction, 2 story Wood frame, drywall, paper thin walls, 2ea *Cisco 802.11 N access points.

Installation:
Upgrade from old Comcast system to X1 Triple Play, with all bells and whistles. Xfinity TC8305C Modem, Xfinity XG1-P DVR Hub, Xfinity RGN-150N Boxes.

Had to assist the technicians with X1, not as versed as I in 802.11, or RF protocols. HSI.....Had to finish set up of modem myself. Tech unable to set-up local LAN He set up Modem, connected one computer, then threw his hands up...

Issues:
X1 operating system is very buggy. Screen freeze, random reboots, lock-ups and sluggish performance is a daily issue. Very irritating to have to reboot the Xfinity RNG-150N boxes several times a day (4ea). The Xfinity XG1-P Hub (DVR) not as bad but not great. Not as many reboots but looses DVR service several times a day. Picture Quality is not as good as DirecTV (Former Customer in FL)....Never Lost Picture, not even during Hurricane Charlie..2004!

Comcast HSI. If you want to use Internet after Midnight, its great, very fast and no streaming issues. However if you live the normal American lifestyle, the 105Mbps (Shared Cable Bandwidth) quickly morphs into overpriced Dial-up speed! During peak hours....Which seam to last from 3PM to around 11 or so at night. The best I have gotten for Up/Download speed was 29Mbps/123Mbps at 1:30 AM! During Peak hours, the best I have gotten was 17Mbps Up, 9Mbps Down...... Worst?..... Unable to connect to server!

Why did I leave DirecTV? Moved from FL. Comcast existing service at new residence. Not the primary Comcast subscriber at this address, so Im stuck with what subscriber wants.

Lastly, This is my experience, If you are a Comcast worshiper, Im sorry, but this is what we experience. I wish it worked! Deal with it.

CHSI speeds

Is that a wireless connect speed? If hardwired, are you using Cat 6 all the way through from the modem to a gigabit ethernet card in the system? What do you get when you go to speedtest.comcast.net?

Re: CHSI speeds

Those speeds were from speedtest.comcast.net.
Yes, Cat 5e, 6 Gigabit hardware all throughout system. All hardwired equip is Gigabit T10/1000.
Wireless N 2.4Ghz & 5Ghz, for all wireless equip.
Wireless download speeds through speedtest.comcast.net run about 65-79Mbps off peak, around 9Mbps during peak.
These peak time results are the lower values, speeds are all over the place during peak.

Re: CHSI speeds

Sorry to take so long to reply. Things have been kinda busy. read this »en.wikipedia.org/wiki/Category_6_cable Cat 5e is NOT the same as Cat 6. You have to use Cat 6. If you use 5e, you still can bottleneck.

My Other Reviews

·Integra Telecom
The fact that Comcast Business sales never disclosed that you are required to lease their modem if you want to lease a static IP address, shows they have poor communication to start. Perhaps you can ask the sales rep for some sort of credit due to the miscommunication? Nope, they're done with you, have to call a different department to request that (after another department just told you to contact your sales rep for a credit request).

Once you do get their leased modem (did I mention it is $13/mo to lease?), pray it works appropriately from the start. Otherwise you will have to schedule another technician visit because they do not allow you to do a self-install, even with simply swapping out modems. Talk about efficiency.

Issues with the static IP? Be prepared to jump through hoops. Their support team will tell you one thing one day, and something different the next. There's no consistency. You have to cycle through tech support agents to request an escalation (if they even let you), and then pray it gets to the right person.

Latency isn't all that great for a business class service. If only there was better coverage with FTTB/FTTH providers, Fiber/Ethernet will always perform better than DOCSIS. No hassle dealing with unreliable DOCSIS modems.

What a mess.

I am paying for Comcast "BLAST" 50 Mbps down internet. I use my own router (Linksys E3200) and modem (Motorola SB6121 DCS3.0). I am paying for 50 Mbps down, I get 1-2 Mbps down on a good day. I have called Comcast customer service 20 times in the past 3 months to try and get my speed unthrottled, or at least to 50% of advertised, they always say "it's fixed, it should work now" and it never gets above 8 Mbps. It is usually below 2 Mbps down, which is pathetic and frustrating. If you can avoid this ISP, I recommend it. Comcast is terrible and their "tech support" doesn't even understand their own services, technology, plans OR policies. Terrible.

same problem

I'm having the same problem with the same package and have been having it for months, called for my 10th time today. When I called last and said the words "you are throttling my upload", it magically got fixed the next day and was good for less than a week. Funniest thing is I'm in Maryland.

No Throttling

Comcast is NOT throttling you. You either have a provisioning issue or line/signal issues that need to be addressed. I suggest you post over the Comcast help forums at this site so the members can help diagnose your problems.

Re: No Throttling

they also block port 25 only to admit it years later. Comcast is an Extortionist! They double dip and blackmail. Ask Youtube! We are paying for bandwidth and there is no way we are getting it. They hide and lie. Pass Net Neutrality!

So I went from living at my own place with FiOS in College Park (with no issues) to living with my parents until I find a job in August. They have comcast, when I first moved in there was serious upstream issues with no download issues. So I called on behalf of my parents (they don't notice the 90% packet loss because they dont use upload all that much), and after talking to five different people who instead of listening to my issue just reset the router over and over, Finally got an appointment schedules for a technician to come out a week later. He came out, replaced the modem but the problem persisted. So i call comcast again, get patronized by another 5 drones who restart my modem and tell me to clear my cookies and finally talk to a networking person who actually knows what they are talking about. I told him my speed test results (17ms ping, 85mpbs download and a times out upload), he sent a maintenance because apparently there was noise on the upstream line. In all, by the time the issue was resolved and the line was fixed it took two weeks of not being able to use VOIP, play any games, use skype or anything requiring upload. Now, several months later it is happening again and even with the confirmation numbers of my previous visits, no one in their support can find a record of me having an issue. I called them 4 hours ago with 50% packet loss up, and threatened to cancel service and go to FiOS, and now my upstream connection is working just fine. That shows me they are probably throttling upload speeds. I strongly recommend choosing another ISP over comcast, Worst customer service and reliability I have ever experienced.
