[AZ] Frequent Interrupts & Slowness in Cox HSI http://www.dslreports.com/forum/r20652295 en Wed, 11 Nov 2009 13:08:14 EDT Wed, 11 Nov 2009 13:08:14 EDT Re: [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20799376 CoxTech1 : Wow, I know we discussed the possibly of the new router also being faulty but what were the chances of that actually being the case?

So on Friday last week the Field Tech Supervisor I've been working with came out to my home himself. He spent over 3 hours trying different things and finally came to the conclusion that it was in fact the new router I had purchased. It must have been causing enough network traffic (maybe floods or broadcasts) to reduce the performance of the entire TAP.

I am guessing the reason we didn't find this earlier is because every time we did our bypass tests we didn't wait long after disconnecting the router. I think the rest of my neighborhood, or possibly a leg up or so, was probably still timing out the bad packets from the router each time we did those bypass tests. In addition to that every time the Field Tech's did their tests directly at the TAP this router was plugged in. Explains why this has been such a confusing and frustrating process.

Lessons I learned and hope others can take away something from as well:
1- To do a bypass test wait maybe 30 minutes after performing the bypass to allow traffic to timeout. This should help remove broadcast floods from the picture.
2- Don't replace your cable modem until you have a Level 2 or above technician check the history logs against it first. Apparently the logs are bound to the MAC or something so replacing the cable modem too quickly will slow down troubleshooting because logs won't be available to take into consideration.
3- Don't buy brand new Netgear equipment? I think I'll stick to Linksys, DLink or Belkin.
4- Humility]]> http://www.dslreports.com/forum/remark,20799232 Wed, 16 Jul 2008 09:40:22 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20753012 pweegar :

My router ended up dieing. So I replaced it with a Netgear FVS114 and my connection seems to be stable. However, my speed is horribly slower than it should be. On the Premium Package I should get "up to" 15Mb (and possibly PowerBoost moments near 20Mb or so). I would expect that my lowest speed in the "up to" range would be at least above the cheaper Packages. But I'm averaging (downloads) 3Mb and bursts to around 6Mb with the new router. But I'm not sure it is the router because I've bypassed it and connected my computer directly to the cable modem and the speed didn't change much (I burst to 6.5Mb/7Mb) directly connected.

I did send CoxTech1 my MAC address and the reply was that the modem\connection looked good. I'm stumped on what could be going on though. I did have a bad router but that doesn't seem to have been the entire problem - there is more to this. In fact I wonder if whatever the other issue is, could it have caused my router to crap out?
You might consider trying a different modem. I had to change both a modem AND a router earlier this year. I had a number of problems connecting to the internet. Cox said try a different modem. I did. Didn't help. Finally decided it was the router. New D-link and it works well ever since. Altho, at times, speeds do get really bad, but I attribute that to being online during peak hours (evenings, say between 6 and 10-11pm).]]> http://www.dslreports.com/forum/remark,20753012 Mon, 07 Jul 2008 11:54:05 EDT Re: [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20739003 wasabiaz : Quick update.

Maintenance says the tap checked out fine. I had a senior field tech come back out today. He ran some extended routing tests while plugged into the tap and some load tests. He confirmed that it does not appear to be the house or the tap. The problem is happening "up stream" according to his load tests.

He has escalated the issue to Engineering. Due to the holiday weekend, however, I should not expect anyone to look at the incident until next week though. It might take engineering time to figure it out as well because they'll have to analyse the segment/etc.. I'm guessing routers, layer switches and so forth. Those are usually tough to troubleshoot in my experience. So I'm in this for awhile still. Don't think there is any chance of getting a credit either - every time I bring it up on the phone with support the topic seems to change or I get put on hold. So I don't expect that either.

In summary to date:
-Interruptions started first of June.
-Slowness started first of June that we know of.
-Replaced router with new.
-Replaced cable modem with new.
-Interruptions solved with new router, slowness continues.
-Over past 2 or 3 weeks we have been visited no less than 4 times (probably a couple more than that) by field technicians or maintenance.
-Maintenance checked tap = ok
-incident escalated to engineering = in progress/]]> http://www.dslreports.com/forum/remark,20739003 Thu, 03 Jul 2008 20:22:31 EDT Re: [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20712463 wasabiaz : Remember the world doesn't resolve around me? Wow. I hope I'm not coming off like a jack ass that is only focused on my own needs. I'm only posting on these forums to share with others that could be having similiar problems. I do vent a bit about my frustrations but that is typical for the situation I'm dealing with in regards to support. Everyone vents a bit. But I have been dealing with this internet problem for several weeks now (I only started posting when I ran out of other things to try).

As for the call back we didn't receive one yesterday. However, I did get one this morning. I think he was a Field Tech Supervisor or something. But he said that the paper work for the maintenance crew was never filled out and that is why the incident was closed. So I sat around all week waiting for something to happen that never was going to happen due to whatever glitch (computer or human doesn't matter).
I am supposed to have 2 field techs come to my house this morning. They added me as a second visit in a time block with another scheduled visit - I guess that is how they wedge in cases like mine? Anyways, I'm waiting for them to arrive any time now. Hopefully they can fix the problem this morning. I really hope they don't come out to perform the same tests that the other person did on Monday - just to fill out some request for maintenance to come back within 3 days or whatever.. We'll see.

No kidding the world doesn't revolve around me. I'm just trying to share my experience with others that might be interested..

I called Cox Tech Support again last night and was instantly bumped over to Level 2 by the First Call group. The level 2 person read through my logs and I gave him the number off the business card for the field tech. He called. Told me he'd have the guy call me back (which never happened). Basically I was told that phone support can't see requests for maintenance so they don't know what is going on.

I called again this afternoon to again inquire status. (Reminder that I have been calling the Field Tech's cell # listed on his card as well). First Call group tried to triage my problem again. Once again "levels are excellent" and "you're internet is fine". Reboot this. Reboot that. Bypass this. F that.

At this point I'm waiting for a magical phone call from someone that has a clue. But I'm guessing I won't get this phone call as it is Friday afternoon. Counting my eggs before they are hatched? We'll see. That's my update for now.
My Speedtest.net results are still 3MB/Down 3MB/Up and my SpeakEasy tests are still 1.1MB/Down 3MB/Up. No change in this since last week. Although I must say my use of the Internet has greatly reduced as these are for sure "burst" rates and my typical speed is probably half this.

I am very upset that I'm paying for this.]]> http://www.dslreports.com/forum/remark,20709462 Fri, 27 Jun 2008 18:16:18 EDT Re: [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20690490 CoxTech1 : I refer to the previous work order as in the one you just had. As far as signaling and cabling are concerned, there is more than enough capacity on the lines and in the wiring in your home to support all services. I have every service Cox offers and to not experience any issues. The only thing that might come up in terms of wiring is is you are still using any older RG-59 coax cable.

I'm curious and possibly confused. A previous work order? And is being referred to a supervisor a good thing or a bad? Thanks for checking on this and letting me know.

Sort of off-topic - but I thought that since my cable and internet share the same source at my home POC that wouldn't the addition of on-demand cause a signal problem? Are the frequencies or bands so different that one wouldn't compete with the other? I ask only because my problems really started to be noticable when on-demand was turned on. Coincidental, maybe, but it seems odd to me that I've had internet for a number of years and for it to just go out like this seems odd.

Internet is slow to non-existant still. The problem is coming "from the tap" and not the house connection according to this technician. He was very suprised about the slowness as well and mentioned that he hasn't seen a problem like this in years. He found that only one other person on my "tap" has Cox Internet and they are not connected at the moment but would most certainly be experiencing slow internet as well.

He escalated the ticket to the next level. I can't remember the actual group name but it was the engineers that had access to the area tap. They have 3 days to respond but they apparently don't notify or communicate to ask if they have resolved the problem. So I guess its a waiting game now. Pretty much looking at another week with horrid internet access that I am paying $60 for. :(

I'll post again if I notice any difference in the next few days. In the meantime, anyone know if Cox will comp me for my last month's payment now that they've confirmed the problem is THEIRS and not mine? Hell, I've got far more than $100 in new equipment that I apparently didn't need - the least they could do is comp me from the $60 payment for service I'm obviously NOT getting. Anyone know if this is possible?]]> http://www.dslreports.com/forum/remark,20687135 Mon, 23 Jun 2008 17:06:07 EDT Re: [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20678662 BinRoanoke :

Well, that bit basically said it started a ranging request with the cable company head end, but it never got a response back to the request.

Downstream value is good, but Upstream is requiring a high amount of power. My guess is that when the problem happens, error rates went really high and the Upstream power went up over 50. Higher power levels mean that it is having to fight through more noise to get the transmit signal back through to the cable system equipment.

Only thing you can do is try a different modem. Beyond that, it looks identical to my situation, which I personally think is a problem at the node or even further upstream in the cable system.]]> http://www.dslreports.com/forum/remark,20678662 Sat, 21 Jun 2008 20:54:58 EDT Re: [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20678557 Chevron : This is exactly the same problem I have been having for months.

Over and over again... many many times. Happy to post more if it makes a difference. Each time I lose connection on my online services and the modem goes through a reset.

My stats at the moment look like this. I'll try to get a copy when it's lost connection.

Had several calls into the phone support, e-mail. A representative came to my home weeks ago and offered that it might be the result of work in the area, and I agreed to wait 3 weeks to see if the problem resolved. No, it hasn't. Desperate for answers.

Speedtest.net shows around 3.5Mbs typically and SpeakEasy is 1.5Mbs.. Not sure why Cox would refer to a site that shows a slower speed but that's how it works some times.

That's generally the same type of SNR and Power Level readings I'm running into, so it looks like we're having very similar issues.

I got a call a while ago from someone who said that my transmit level had gotten up to 51.5, so they have scheduled a visit for Monday, including instructions to check at the tap. The current thinking is that there may be a problem at the tap or further upstream (IOW, not the internal wiring in the house). They said to tell the tech that I had a bad forward and return. They also took a look at node-wide statistics for the node I'm connected to and noted that the transmit average was 49, which is on the high side.

One thing that was suggested was to rewire the modem run so that it goes direct to the block, thus eliminating one splitter. I think I'll take them up on that. In any case, that will give me about 3dB more Receive Power and 3dB less Transmit Power requirements. From there I may also go for a Directional Coupler instead of a splitter to provide signal to the TV in the room where the modem is at. That should get 1-2 more/less dB (Receive/Transmit).

At least if there is no immediate resolution, I'll have the signal pathway cleaned up more...]]> http://www.dslreports.com/forum/remark,20673107 Fri, 20 Jun 2008 14:19:48 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20672914 wasabiaz : BinRoanoke,
It stopped doing anything (download/upload) and upon a power off and back on again only two LEDs would come on. I don't remember which. But it wouldn't complete a boot (unable to get an IP or connect and my NIC reported "disconnected"). I tried several times so I'm not exactly sure what was wrong - but it wouldn't come online enough for me to try anything else. That kind of "dead" I guess. :)

Well, you and I shared the same router and have the same intermittent dropped sync issues. How long did you have it? I've had mine for at least 4 years now. By "died", what exactly happened? Does it not power on at all or does it power on, but never starts a boot?

I have now purchased a brand new cable modem and had it activated on my line. So I've fully replaced the cable modem, ethernet cable and router with new equipment. I've tried safe mode w/networking enabled. I've tried bypassing the router.

I was *finally* able to get to "Level 2" support on the phone with Cox tonight. That person said my modem pings just fine. Great. I went through the entire routine with First Line and Level 2 (power this off, power that off, power this on, power that on, reboot this, safe mode that, disable this, enable that) etc.. And my downloads actually got worse. I'm now looking at an average 1.1 Mb download!

I guess Level 2 is as high as I can go? I now have an appointment on Monday between 1-3pm. Let's see here, I honestly doubt Cox is going to comp me for my poor network performance this entire time and now I have all this new equipment I may not have needed in the first place? Ok - the router did eventually die, but was that on it's own or did something on the network cause that?

Anyways.. I'm very frustrated. And now I have to WAIT until Monday to have someone come out to look at things. I can see it now. They'll check the POC, look at my cable modem, have the power off/on routine.. Maybe even add one of those power boosters or whatever (those things that burn out all the time but solve the problem temporarily so the incident can be closed?) and I'll be back in this situation. Argh.

I mean no offense to anyone. I know everyone is just doing their jobs, and in some cases more than they need to be (CoxTech1 for example has been very responsive and helpful in PMs). Just frustrated that this problem always ends up to be "mine not theirs".

Yup. Several times. Even long delays between each attempt.
Is your PC tweaked? IE TCP window is an appropriate size?]]> http://www.dslreports.com/forum/remark,20668611 Thu, 19 Jun 2008 17:11:04 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20667632 wasabiaz : Yup.

Modem -->router--> PC?

Great success! High five!]]> http://www.dslreports.com/forum/remark,20667232 Thu, 19 Jun 2008 12:29:07 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20667137 wasabiaz : My router ended up dieing. So I replaced it with a Netgear FVS114 and my connection seems to be stable. However, my speed is horribly slower than it should be. On the Premium Package I should get "up to" 15Mb (and possibly PowerBoost moments near 20Mb or so). I would expect that my lowest speed in the "up to" range would be at least above the cheaper Packages. But I'm averaging (downloads) 3Mb and bursts to around 6Mb with the new router. But I'm not sure it is the router because I've bypassed it and connected my computer directly to the cable modem and the speed didn't change much (I burst to 6.5Mb/7Mb) directly connected.

I did send CoxTech1 my MAC address and the reply was that the modem\connection looked good. I'm stumped on what could be going on though. I did have a bad router but that doesn't seem to have been the entire problem - there is more to this. In fact I wonder if whatever the other issue is, could it have caused my router to crap out?]]> http://www.dslreports.com/forum/remark,20667137 Thu, 19 Jun 2008 12:03:58 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20666256 CoxTech1 : Send me a PM with your cable modem MAC address and I'll see what I can find out.]]> http://www.dslreports.com/forum/remark,20666256 Thu, 19 Jun 2008 08:54:53 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20665737 peterman25 : Was there a resolution to this issue or possibly some information to pass along? I am having extremely similar issues in Laveen.

*Modem and router don't appear to lose connection
*Gmail and messenger clients lose connectivity
*FTP transfers interrupted
*Interruptions are short in duration, but frequent.

I have a surfboard 5120 connected to a Netgear WPN824. I haven't contacted cox just yet in hopes that I might find a resolution myself.

Thanks.]]> http://www.dslreports.com/forum/remark,20665737 Thu, 19 Jun 2008 02:31:12 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20654901 CoxTech1 : I can take a look at the modem if you PM me your cable modem MAC address.]]> http://www.dslreports.com/forum/remark,20654901 Tue, 17 Jun 2008 08:56:34 EDT Re: [AZ] Frequent Interrupts http://www.dslreports.com/forum/remark,20652791 Fubar : Modem levels and log,

Have you tried without router in place?]]> http://www.dslreports.com/forum/remark,20652791 Mon, 16 Jun 2008 19:15:06 EDT [AZ] Frequent Interrupts & Slowness http://www.dslreports.com/forum/remark,20652295 wasabiaz : [edit: I did browse the forums and found similar complaints but none listing an exact match or location so I decided to post in the off-chance of getting help specific to my area or that other lurkers in my area could be having the same problem.]

I seem to be having problems with my connection. I have called Cox Tech Support a couple of times and had my cable modem 'reset' and 'tested' and all seems fine on their end. But my interrupts continue and it has been going on for several weeks now and my hope of it just going away just doesn't seem to be coming true.

Any tips or suggestions on how to resolve this?

My cable modem never appears to lose connection. My router never appears to lose connection. My internal connections seem to be fine (my wife will typically use my computer and RDP to her computer using the internal IP and that connection is never interrupted). However, when my wife is transferring files UP or DOWN from her FTP server she is often interrupted and has to restart. Our MSN Messengers frequently disconnect and reconnect. I can't play a single online game for longer than 10-40 minutes without a disconnect. Doesn't matter what it is, World of Warcraft, Age of Conan, Battlefield.. The interruptions are frequent, several times an hour.

Cable modem 'power off and on' and router resets do not change anything. Connection always appears fine and the interruptions are always short in duration. But it's all services when it happens (not single connections or ports).

My network speed tests have been averaging 12Mb/down 3Mb/Up (Premier Package) - though the most recent was 10Mb/down 3.5Mb/Up.. Most of my friends are reporting 20Mb/down 4Mb/Up on their tests. From what I can tell this might be happening to one of my friends that lives directly North of me by about 4 streets. But other friends around the City don't complain about issues. And Cox Tech Support says there are no issues or problems. I'm in North Phoenix.

Are there any tips or suggestions on what this could be or how I could troubleshoot (or fix) this? Maybe tips on what I should tell tech support if I were to call again?

Thanks..
