WTF is up with Comcast lately?

[The Snowman]

Comcast did a huge upgrade to their internet speeds awhile back

could be that some have not fully reset their EMTA's Cable Modems etc...

The only real way to reset your cable modem or EMTA

is to unplug the module AND remove the battery.

make sure your router is disconnected from it first then unplug and remove the battery and let it sit OFF for 30 seconds to a minute.

then re-install the battery and plug in the power cable leaving the router disconnected until all the lights on the front of the EMTA or modem are reset

For EMTA's make sure that the line1 and line2 lights have locked in. if they are blinking then the lines are still re-activating.

once all the lights are locked in then reconnect the router.

it should now pull up the new ip address etc...

check your connection all over the house.

if you still are getting slow speeds then the best you can do is contact comcast and let them know this is happening in your area.

and yes the reps are right to put blame on your individual modules that are not comcast approved. why? because it is not their equipment and there is nothing they can do to help you out. so by telling you this (which is fucked up and something i never did and would bitch at the phone people who did) they have a readout of the performance of your equipment so they can tell you if the upstream and downstream are up to par. everything else woud be internal to your network.

Been there, done that. I actually got the modem I have now when they did the network upgrade.

But, like I said, I'm going to get one of the newer generation modems Friday when I'm home.

I just seen that denno posted a soft reset of the modem and most people assume thats enough, but it doesnt fully re-cycle the equipment. for that you need to fully power off and back on...

hopefully that helps your problem.

I too have had internet problems, but i cant say with 100% certainty why.

I am sure it will either work itself out on their end in time or there really is a problem with output and comcast is on the decline.

I have no idea.

I plan to talk to my friend who still works for comcast this week as we need a new drop and i need some compression fittings. The addition is almost complete and i need to get ready to run all the cable.

there will soon be cat5 through out the house, and at minimum 12 cable outlets.

I am in for a nice project.

and as for the amp comment.

the problem is that when you amp an EMTA or Modem you end up with data loss still and you will get more errors and with the EMTA phone quality will suck and drop alot of calls.

your modem EMTA should be on an isolated line from the rest of the cable outlets via a good splitter and should be on a 3.5 loss at the drop (feed)

everything else is a matter of picture quality and an amp and proper splitter usage will help.

Chuck,

The last 2-3 weeks with Comcast has been a night-mare over here. Either way too slow loading or not loading at all.

I was invited by Comcast to be on their "inner-circle community" of 500 participents. I was surprised... I got picked.

I'll have to ask them WTFIU with this problem.

You should register with "OpenDNS" I re-installed their DNS number servers when I first started having the problems with Comcast's DNS servers. Now, no more problems!

[KillBill]

At least you have something other than Charter......they really SUCK

I don't follow this. (and I'm a techie)

[ptk-napalm]

I don't follow this. (and I'm a techy (fixed it for you))

Well.. what I was trying to say is that most bottle-necks are caused by clogged "DNS". Comcast for the last 2 years has been ratty at best trying to hit their server to get the translation from what a person types in & what its true # is.

I was turned on to "OpenDns" a couple of years ago & I did see a improvement in ping times & such. I then had a few problems with my alternate DNS & only listed them as a secondary backup DNS.

When I started having problems with long hang times trying to access a site, I then added in their primary server #.

It seemed to fix most of my problems with hanging forever to get to a site until recently.

Lately, I have been seeing problems again, plus my TV is starting to have more problems also.

I'm still running the "OpenDns" right now but I can switch it back to Comcast's in a heart beat if needed.

The ping times with Comcast has been getting longer as the years go on, I once was running a 10 ms back in 1995, I now see 100 ms pinging Symantics site on average.

I hope this answers your quandary as to what the heck I was talking about?

[OreoGaborio]

So how do I do this OpenDNS stuff?



EDIT:




And this is AFTER I just unplugged my router & popped the battery out.

[Kurlon]

OpenDNS won't fix that problem Oreo.

[ptk-napalm]

Here is mine right now.




My speed test from Boston.




Here is Philly now.

[ptk-napalm]

Google "0pendns.com" register on the site & follow the directions as to setting it up. Make sure you go into settings & turn on "smartcache" after you have completed installing it. If you have a router it is a little diffrent setting up. But just follow their directions & make sure you copy Comcast's DNS #'s just in case you want to switch back.

I hate how comcast makes you go through their stupid troubleshooting when you call them too. I usually just pretend to unplug the modem and routers and stuff. I wouldn't be calling them if I hadn't already done that and it still didn't fix the problem.

Dude, DNS settings aren't going to affect icmp latency...

[The Snowman]

Well, looks like some of my issues were the modem. I went to Comcast and exchanged for a newer model and right away, I'm getting 26mbps down, 3.5mbps up.

And pingtest scores me an A.

[R-S-V]

Is there a way to check if I have one of the newer modems already? I changed mine about 6 months ago and like to know if its worth exchanging

Mine were two completely different modem models.

[jwm2k3]

Fios FTW. Comcast would bog down on me at peak times, the more using it the slower it got. Fios is WAY faster for my internet gaming!

[MissTwisties]

Comcast sucks. Oh the irony...I just applied for a job on their website. I hear their work environment sucks just as much as the services they offer. Joy.

[ptk-napalm]

Read message # 31 again please.

[ptk-napalm]

Mine were two completely different modem models.

Mine is over 10 years old, I think it is time for a new model.

[The Snowman]

Well, it's happening again. Even after the modem, swap. This time, I believe that it's the D-Link wireless N router. Every time I reset the router, it gets faster for a period of time, then slows so I can't even contact google.

The router is a year old, so it's out of warranty. I think I'm going back to Linksys, since I have never had issues with them. The only reason I went with D-Link last year is that at the time, no one else made an N router.

I had A-F from pingtest over the weekend. Service was as unreliable as Jim's straight answers.

[Cerberus]

also, if you want to do a test of your dns servers speeds versus others out there that are public and usable, check this out. it will also offer some dns options

http://www.grc.com/dns/benchmark.htm

i have not used comcast's dns servers in years, they tend to be flaky.

if their service has a consistent weakness, their dns server are defintely it.

[R1]

You are aware that they limit your bandwidth per month right?

If you exceed that then they slow down your service, in some cases shut it off completely

absolutely, and really, i think thats kind of fair.

but for most people, i suspect that some of the connection issues are dns related where as connection SPEED issues are simply bandwidth saturation in the infrastructure..
