Your mileage with them may vary, but they are a lot better than what they used to be.

In terms of Shaw's network security/setup, some aspects of it are open for exploiting, but lets leave that part alone, my and most others' Shaw connections work just fine and do not need someone messing up the party. A few years ago I got in some nasty shit with them over certain programs being ran out of curiosity that were not meant to go out to the internet, and crippled their entire network for a couple hours. Calling their network operations centre in Calgary just to get the modem back on was not pretty but at least it was settled like gentlemen and no lawyers (accidents happen). A little laugh with that one though, trying to call internet abuse department because I knew they would be easy to deal with by playing dumb did not work, got recited the phone number for their NOC duty admin and hung up on (damn long distance number too).]]> http://www.dslreports.com/forum/remark,21158304 Tue, 23 Sep 2008 22:20:59 EDT http://www.dslreports.com/forum/remark,21152161 anon : Actually i have been extremely patient throughout most of the process, the one exception was their accusation of me modifying firmware on modem and pulling 500 ip's from all their service areas. And this is what was causing me to have problems.

However the claim was only partially accurate without any real investigation. It turns out i had some defective entries on my firewall(I wont tell you which ones, can't have everyone exploiting SHAW now) requesting all those IP's, and it only lasted a matter of an hour which i was pulling them because the night before i was messing around. And the modem was offline most of that time anyhow.

I will say one thing however, their network is setup poorly, and any blow joe can basically get as many IP's as they want, i dought they fixed the issue.]]> http://www.dslreports.com/forum/remark,21152161 Mon, 22 Sep 2008 20:50:04 EDT http://www.dslreports.com/forum/remark,21151644 anon : Well it was fine for 3 days, then today sometime it went offline again.

I checked the SNR and it was around 54 on the upstream, bounced offline a couple times while in the modem. I didn't go into depth cause it came back up right away, but the logs were timing on TS and resetting the MAC or some such.

Its up now, and speeds are good.

As i mentioned, I do not have Cable TV hooked up. I do not have any copper pipes nearby to ground the adapter. However I do have a circuit tester, and the ground is good.

I won't even go into as to how much they already checked.

I'm not calling tech support anymore they will just send out the same people who can't do anything. I already called them once for free month. I actually don't care too much anymore. Cable Internet is just unreliable in nature and I am going to live with it for now.

I have had cable with 3 separate carriers, each time its been unreliable, no matter what the tech's do.

But if it gets worse, I will be calling corporate again, and probably just discontinuing service.

I'm praying that the local Telco here can provide me with a dedicated connection that doesn't break my bank. If they can't ill just live without internet at home.]]> http://www.dslreports.com/forum/remark,21151644 Mon, 22 Sep 2008 19:12:08 EDT http://www.dslreports.com/forum/remark,21145183 cableguy84 : for the upstream anything between 37 and 54 is acceptable
and downstream it is +7 to -7
Those are the Shaw standards, but if you have had a shaw tech out they should be fine, plus the techs on the phone can check this as well without having to reset your modem.]]> http://www.dslreports.com/forum/remark,21145183 Sun, 21 Sep 2008 12:39:23 EDT http://www.dslreports.com/forum/remark,21143927 donaldk : No, I have friends that have service in that area without modems dropping like that. I have two modems in service myself, my own on Off Beverly St, and my parents up by Albany and Shuniah.

There is a trick you can do with the modem, and that is you go to 192.168.100.1, unplug the modem, plug it back it, and refresh the page, go through the menus to get to the signal levels. Once the modem locks onto Shaw cable's cap file you will loose access, so take note of the URL you are at, and powercycle the modem again.

Generally, acceptable ranges for DOCSIS platforms are:

TX level: 50dBmV
RX level: 7 dBmV to -7 dBmV (although most systems can take up to 15 to -15 range, I would be concerned if you fall below -7)
RX Signal-to-Noise: minimum roughly at 24 to 30 dB (this depends on what QAM level shaw uses)

Check your TV signal on Channel 14 to Channel 15, these two channels should be coming in clear, or if you do not have TV service and they put their notch filter on it, you should at least see the picture, but audio on Channel 15 might be snow, downstream sits between these channels.

After all this, again you will have to call Shaw tech support, as much as you might want to 'rip their head off' on the phone, keep your cool and let them know the problem still persists and that you demand credit to your account (enough of this will really get things moving). Also, do not bother mentioning exact signal levels to Shaw's CSR's because they will get their panties in a bunch wondering how you got the data.

Edit: For the five modems that I and my friends have set up, none have dropped off except for scheduled service periods by Shaw in the middle of the wee morning hours.

---- My Modem's Signal Data ----
»192.168.100.1/signal.html

Downstream Value
Frequency 117000000 Hz Locked
Signal to Noise Ratio 36 dB

Upstream Value

Power Level 51 dBmV

--- end snippet -----

My upstream TX power is a bit high, but when I did this my modem did a wierd fault (because I was getting it during sync), I am sure it ranged down to the mid to high 30's. Downstream sits between channels 98 to 99, but Channels 14 to 15 are the closest with signal to view. Upstream is on non-TV Channels between T-10, and T-11, Channel 2 on the TV should come in strong.

if you can get a grounding wire and run it from that 2 way splitter to something grounded that may help.
cant hurt to try it.]]> http://www.dslreports.com/forum/remark,21131018 Thu, 18 Sep 2008 12:36:02 EDT http://www.dslreports.com/forum/remark,21130821 anon : 3 Modems changed(connected to UPS, tried without UPS, different outlet, original had power adapter not built in)
Im assuming its grounded at the pole.

All Internal wiring wiring changed/2 way adapter/drop cable and whatever else out in the field. Just the 2 way adapter to the modem and to the shaw provided voip bridge.

The thing is, it will work perfectly well, full speeds, no problems, then randomly when I'm not home or in the evening it drops off completely, and if it does come back for sometimes days. If it does come back after power cycle the speeds are slow and it drops off again. After a couple of days it will be fine with no signal issues.

Doesn't matter if its raining or sunny or windy or calm out side.

However there is a tree branch hanging over the lines, which they have consistently said is not a problem.

I am getting City to trim them just in case. Because I have seen tree branches pulling on cables before that have caused intermittent issues.]]> http://www.dslreports.com/forum/remark,21130821 Thu, 18 Sep 2008 11:55:57 EDT http://www.dslreports.com/forum/remark,21124166 cableguy84 : it is unlikely an equipment issue that far down the line or shaw would have large amounts of support calls from your area, and they track that.
They change the modem?
is the cable line grounded?
do you have an aerial line or under ground?]]> http://www.dslreports.com/forum/remark,21124166 Wed, 17 Sep 2008 10:06:25 EDT http://www.dslreports.com/forum/remark,21120989 anon : Hello, I am putting a word out their for anyone in the Thunder Bay Area. I have had 6 technicians, 2 of them senior techs, multiple phone calls to Shaw over the past couple months in regards modem not coming online, they have changed everything imaginable up to the trunk line. But refuse to check their own equipment in their office.

My question to anyone in the John Street and Algoma Area, is anyone else having random issues with the modem dropping off for hours or days and then just coming on again?

It started out as both Phone and Internet issue, but the phone side seems to be stable.]]> http://www.dslreports.com/forum/remark,21120989 Tue, 16 Sep 2008 18:20:48 EDT
