internet speed
I am interested in upgrading to Extreme 105- is it a big price difference, and do you get a substantial increase in speed? Also, does it help "spread" the signal farther into the house?

Comcast telling me I need to replace my SB6141 Modem.
The past week my internet has been having issues. Has gone down 3-4 times for about 20 mins minimum time. Called comcast 3 differnt times and got 2 answers. First was my modem was on the EOL list and needs to be replaced. 2nd person told me I do not need to replace my SB6141 and if I have any other issues to call and have a technician come out. 3rd guy tonight said I indeed need to replace the modem as its not getting the correct updates (I'm assuming firmware) because its on the EOL list and this problem will keep happening. I asked him if he guaranteed that if i get a new modem it will fix my problem and he said yes. I've had this activated for 2 years and not really any other problems untill now. I've read the post about the 6141 being able to get hacked, but not sure if this is related. Is it true I can no longer recieve updates to my modem? Do I really need to purchase a new modem to get stable internet?

Re: internet speed
I have one tv, three computers and a smartphone. We use the internet 15- 29 hrs aday ant Blast is fine (I have limited my netflicks and hulu to low) , but as we don't have high deff, this isn't a problem with those shows, however chosing low from Xfinity's site shows a marked signal degridation ( so I watch all the shaos I can on hulu) and only watch those shows not available elswhere. As for the wireless spread, I've found getting a repeater is a good option. If you want to, you can replace your modem with one that has extended range for wireless. I did that with my inlaws and they now have great reception in areas that before were 'dead' zones.

SB6141 Modem - after firmware update have just one upstream channel
SB6141 Modem - after firmware update have just one upstream channel - had 4 bonded channels upstream.
I tried to resolve with telephone support but the person transferred to a level II tech who had no idea what I was talking about. He said his supervisor has told him there is no one else at comcast to answer/resolve this question. Apparently the blast 75 profile/config file for the upgraded firmware is not telling the modem to use 4 channels.
the other possibility is that comcast's CMTS is not allocating. Since CMTS has something close to 5 to 1 more upstream channels available than downstream it can't be a lack of channels.

Intermittent connectivity issues
I'm having occasional problems with my connection - it's making it hard to do anything for more than 20 minute at a time (Netflix, MMOs, etc). I have 25/5 speeds, so I'm not expecting blazing fast downloads, but it shouldn't be dropping me entirely.
All devices are connected wirelessly, unfortunately. Cable outlets are not in conveinet places.
Ping tests to comcast.net are showing 4-5% packet loss, which seems a little high.

Arris TM822 Modem Regularly "Un-syncs" with Comcast
Hey guys. Saw this thread over here.
So I'm hoping that you all might be able to help me shine some light on what's going on with my modem here. It intermittently disconnects with Comcast. Tech came out and said I should try doing the whole Best Buy check and see method - but really don't want to pay for yet another modem to have this happen again. (I've had to get a couple since 2011.)
Router is a Netgear WNR834Bv2 - Haven't had too many problems with my LAN when the modem isn't functioning.
When the modem becomes unsynced with Comcast, the Online light stops flashing and simply goes straight amber:
So, as asked in other threads, here's what I've been able to round up as far as info needed:

Frequent Speed Loss and Signal Drops Randomly
I have been having random drop out of internet and other times my speeds slow down to nothing. The speeds I test range from .12 mbps to 20 mbps these speeds were tested with a wired connection. The weird part is I have seen it rarely only effect the upload speeds when this happens. I have to reset the modem when this happens and most of the time it goes back to normal. I have only had to reset the modem a second time when the speeds dont improve and it only has happened maybe 2 or 3 times I am aware.The other thing happens when I am playing online games at random times my internet will drop completely for up to 1 minute and come back with the same speeds. We have trade in 3 modems in and the problem still contiunes to happen, but only 1 of the modems did die. My modem/gateway I have right now is a Cisco DPC3939 bridged to a Linksys EA4500 router.

1-20 minute intermittent connectivity
I have experiencing a type of disconnect of Comcast internet, every few days my wired computer reports no internet connection for a few minutes, then it recovers. I set up a Linux laptop to ping the Comcast default gateway every one minute. This shows for example in the last 24 hours two incidents of 2-3 minute disconnects. I have a new cable modem/router from Comcast, ARRIS TG862, a few days old, and it made no improvement. I see the ARRIS modem keeps a log file and I found entries corresponding to the ping failures. Below are the entries from one incident at about 07:03 on May 30, and from 10:37 on May 30.
As some diagnosis I made my ping to the default gateway, which is 24.4.32.1, also ping two other responding entitites, .8 and .9 (I have no idea what these devices are). I see during the ping failures that all 3 are failing to respond to pings.
What does the log below mean?
Thanks!!

Degraded speed, self-owned SB6121 - my experience, any hints?
Posting here in case anyone with a similar setup and similar problems can either shed some light, or benefit from my info once this is resolved.
I've consistently received Comcast Internet speeds between 30 and 40 Mbps since the last cable replacement in my yard some months back.
Recently, speed has been in the toilet and everything stops and buffers all the time. My speed now ranges from 250 kbps to 5 Mbps, when using Ookla and testmy. I've ran automated tests over 24 hours with testmy and the results are all within this band.
I [may or may not] have checked speed directly at the cable's point of entry to my yard and [may or may not] have received the same speeds. (Comcast has emphatically informed me that performing any diagnostics myself outside my house is breaking federal law.)
I called in and the first rep told me that my reported 250 kbps was the same as 25 Mbps, since you divide by 10 to get Mb from kb. I explained he was still off by a factor of 100, but he was not buying it. He said he would run a test, then came back and said he got 25 Mbps, "the same as you". I asked him if he actually ran a test, at first he said yes, then he went back to saying my speed was fine because the 250 kbps was what I was supposed to have because it was the same as 25 Mbps. I admit I lost patience at that point, explained the factor of 1000 conversion to the rep, and asked to speak to someone else. He put the phone down and I heard him laughing to his colleagues for a while, but he didn't come back on the line. I hung up.
I called back, and either this rep was already having a bad day or she saw something in the notes from my previous call because the first time I spoke before she was finished she let me know that I needed to wait until she was finished talking. I told her about my speed problems, and her first response was that I needed to contact Motorola about my modem. I asked her how that would help if the problem was the speed coming into my yard, and she said nothing could be done about that. I asked her what that meant, and she went into a spiel about how my SB6121 needed to be replaced, and told me I could find upgrades online at Comcast. I asked why, and she said that the SB6121 topped out at 75 Mbps, which was my current service. I asked if it was still supported, and she said yes. I told her I would be happy with "just" getting 75 Mbps. She then told me that Comcast could not control if Motorola was pushing firmware updates to my modem that were not compatible with Comcast. ? At any rate, I have checked and my modem is running version SB_KOMODO-1.0.6.16-SCM00-NOSH, which looks to be the version Comcast is looking for.
Lastly, I asked this rep how may kb were in a Mb. She put me on hold to ask her supervisor, who looked it up and gave the correct answer. She did give a disclaimer that her level of support was not as deep in the technical details, which I suppose is a reasonable answer. This obviously still does not justify the exerperience with the prior rep who refused to help further based upon his own lack of understanding.
I did press "1" prior to the calls to participate in surveys afterward, but have not received the call back on either call. If Comcast would be interested in discussing my customer experience during my phone calls any further, I would be glad to oblige with transcripts of the calls (I have an excellent memory 
I have a service appointment scheduled. I'll report back. Thanks!

Intermittent latency causing connectivity issues
I am getting intermittent disconnects to a service I am useing. I contacted the companys Customer Support of the service I am useing. They asked me to run some Tracert and MRT test to narrow down the issue. After running a Trace and MTR we found where the issue was takeing place.
The issue seems to be originating from here:
be-33651-cr01.sunnyvale.ca.
I am getting an average latency of 2138 ms and a spike of 4444 ms. This is causing frequent disconnects from me to the service I am useing. This has been going on for aproximatly 2 months now. I could really use some help.
