[CenturyTel] Questions/issues with Zyxel PK5001Z gateway/online

I recently had a field tech come out to check our lines. He was annoyed about having to come out so often and so he decided that since he could find no source of the issues I was having, he'd install a new modem. Well, and I know some of you say this might not make sense, but since the new modem was installed (he took our old Westell 7500 >), our ping times have been frantic, I'm getting randomly disconnected from Xbox Live party chats and on online game lobbies. I don't know what the deal is. And my laptop, which is literally 5 feet from the modem, is getting this first set of digits:

Tracing route to PK5001Z.PK5001Z [192.168.0.1]
over a maximum of 30 hops:

1 10 ms 8 ms 9 ms PK5001Z.PK5001Z [192.168.0.1]

That's not normal, is it? Even on wireless? I have no way of testing my Xbox stats, which blows, so I can't give anymore specifics on that.

Here are my line stats:

DSL Power

Levels Downstream Upstream
SNR 27.3dB 22.9dB
Attenuation 8.8dB 2.0dB
Power 14.4dBm 12.4dBm

Which CenturyLink told me was fine, but I'm not a techy in this area. Any info or advice would be appreciated.

My ping times aren't 'bad', but why are they so all over the place now? On the old Westell modem, they were almost always consistant between 44-46, never bouncing like this. I know a lot of people say a modem's a modem, but this literally didn't happen until we got this new modem.

Re: [CenturyTel] Questions/issues with Zyxel PK5001Z gateway/onl

• Your signals are all good/outstanding. The Power could be a tad lower, but it is OK.

• The ping that you posted is odd. google.com is not 74.125.225.67. That IP resolves to Moffett Federal Airfield (Mountain View, CA)

When I ping google.com I get:

This also resolves to Moffett. So that is odd. I did some research and it seems like some of Google's routers were/are hijacked.

  • That is a side issue. Look at my pings; they are moving just as yours are. That is normal.

  • Your ping to your MODEM/router is high. Do a direct connect and see what your ping is.

    Do you have a link? I see resolution thus:
    And also:
    As I recall, '1e100.net' is Google. A fitting host name as 10 raised to 100th power (1exponent100) is a, "googol".

    Maybe I should not have used the term "resolves to". Maybe I should have said "the location of the IP is".

    The IPs belong to Google (Resolves To). »www.whois365.com/en/ip/7 ··· .224.194

    The following is where I got the location of the IP.

    Several sites like this »ipdb.at/ip/74.125.225.67
    and »www.ip-adress.com/ip_tra ··· 5.225.67

    The point was that we both pinged google.com and we have a different IP in the ping. That is odd, no?

    No, it is not odd. Google uses distributed server farms. I would expect a different Google IP address for a user in Cardington, Ohio from a user in Las Vegas, Nevada from a user in San José, California.

    Ohio user pings Google, gets [74.125.225.67]. Trace route from San José, California:

    RTT is about right for San José, California to Chicago, Illinois. Host name is
    ord08s07-in-f3.1e100.net, where ORD is the airport code for O'Hare International Airport in Chicago, Illinois.

    Nevada user pings Google, gets [74.125.224.194]. Trace route from San José, California:

    RTT is about right for San José, California to Los Angeles, California. Host name is
    lax02s02-in-f2.1e100.net, where LAX is the airport code for Los Angeles International Airport.

    San José user traces route to 'www.google.com', and gets:

    RTT is about right for San José, California to Mountain View, California. Host name is
    nuq04s09-in-f17.1e100.net, where NUQ is the airport code for Moffett Federal Airfield (which the locals still call, "Moffett Field", a holdover from its time as a Naval Air Station).

    It isn't uncommon for providers to use nearby airport codes in host names.

    It is quite common for CDNs (such as Google) to route users to servers closest to the users' geographical locations; with corresponding differences in IP Addresses.

    Thanks for the words of wisdom; but how does this apply to the OP's issue?

    What did they do at Moffett?

    Can we get back to the issue at hand?

    It's virtually the same, aside from the first hop. I'll post specifics in a bit. I'm still getting disconnection issues and CenturyLink tech support is useless on this one :/

    I originally posted this on another question on this forum but if I understand your problem correctly it may apply to your issue also.

    "The PK5001Z (and several other modems) has sporadic issues with its WPS system. I had similar issues with mine and had a friend who is in the business of setting up networks research it and look at the Modem/Router.

    if you go into the router settings and turn the WPS off it will cure your problems. In fact if you turn the feature off on any brand of router it will likely cure most of your disconnect problems.

    This type of issue with this and several other routers is becoming more common. Many devices are confused by the WPS feature and keep trying to reset there ip address or sign off the network sporadically."

    Well, I disabled WPS as suggested and the problem's still ongoing. CenturyLink still insists that nothing's wrong. I get random ping drops using throughout the night, first hop to router's still high and I'm getting disconnected from Xbox Live parties constantly. This is 'so' annoying.

    Just to make sure that we are on the same page.

    The old Westell did not exhibit this first hop ping spike; correct?

    It started when the new MODEM/router was installed; correct?

    If this is correct, call CL and ask for a new MODEM/router, and see if this corrects the issue.

    (Why did the tech come out in the first place?)

    If there is any concurrent Internet activity during a ping test, it will skew your latency. Have you secured your wireless against unwelcome guests? Run a malware check?

    @Irish The tech came out because we were having packet drops throughout the night hours and they wanted to check the lines. He did his little portable modem test and didn't see anything wrong, so he went out and got the new modem.

    @Norman I've done several ping tests, with only one device running (tried on 2 difference devices, actually) and it was the same. I'm ridiculously rural and no one can milk off of us, really. I leave the wireless open incase my little cousin wants to come down and use her iPod lol. Other than that, no one's on my internet. I keep a 'very' close eye on the network activity. And malware wouldn't be the issue, as the problems are almost exclusively on my Xbox. I mean, the bouncing ping times are PC-related, but they're not that bad. It's the party disconnects that plague me.

    As I said above, have CL swap the MODEM back to the same make and model that you had before.

    That is when the issues started; after the the swap.

    So I got the last Westell 7500 gateway in the area it seems, which is the modem we have prior to the Zyxel PK5001Z and it fixed our problems. The pings have stabilized and the problems with Xbox Live have been fixed. All that crap and it 'was' the modem. Go figure.

    See how much more stable?

    I'm a little concerned about the first Power number, but it hasn't been giving me any physical problems, so I doubt it's anything to worry about.

    There is something in that other unit that just does not fit in your configuration. There have been other reported problems.

    So far so good. Just keep an eye on everything in case there is a latent defect in you connection.

    I would not worry about the Transmit Power. The only thing I have seen as acceptable limits is that it should not exceed 15 dBm.

    "Output or TX Power

    How much power modem (upstream) or DSLAM (downstream) is using. Maximum recommended is about 15dB. The lower the power the better for this measurement. Not all modems have the ability to provide output power. "

    What do the speed tests show?

    After multiple trips from the Centurylink team to fix my problem......I have solved my issue. I had DSL installed a month ago and have had Internet disconnects every 15 to 16 minutes from day 1. After all new lines to my house....3 different new modems....and 5 different ports at the phone company, I still had the same problem. I could watch my modem stats for IPV4 uptime and it would count up to 15 to 16 minutes and then it would reset and start back over from 1 second. At the same time this happened I would lose my internet connection...but my DSL signal stayed on. It is the same problem that I have seen over and over on the internet with people playing different online games and getting disconnected with the PK5001z modem. The fix was to replace this modem with an older stlye 660 modem. My internet works like a charm now!!!! Obviously Zytel needs a firmware update for this modem to shut off the IPV4 uptime counter to fix this problem. As this is one of their newest modems in service, there is still no firmware upgrade as of yet. I really like the modem and would like to use it again so PLEASE update the firmware in this modem soon!!

    I am having the exact same problem with my new Zyxel PK5001z modem from CenturyLink. Basically makes playing online games that need to connect to a server unplayable because every 15 to 30 minutes I'll lose the connection to the server. I read somewhere else that setting the modem to bridge mode and then setting up a wireless router in bridge mode would solve the problem, but I am having an issue getting my Netgear WNDR3700 setup in bridge mode. Looks like it might be easier to get an older modem like the 660 and use that instead.

    exact same problem here, because of that cant watch or listen any streaming media, not longer than 10-15 min anyway. I watched for hours that ipv4 counter. Stupid thing and centurylinjk customer service was no help[ either.

    Not to glob onto old posts....

    ...but I am having the exact same problem with the ZyXel PK5001z router.

    I've watched the system log while streaming things, and like clockwork every 15-16 minutes, the internet cuts out no matter what, dropping my streaming connection. Insanity for trying to play a game online.

    Below is a snippet from the system log, showing the 15 minute routine (which logs 4 distinct activities during the drop). Check the time stamps:

    You get the picture....

    The condition is unnoticeable if you are simply browsing the internet because it quickly connects again. Doesn't matter if the connection is wired or wireless.

    Is the only solution to this a new router? Is there something in the settings that can be changed? Is there something on Century Link's end? The above log was created with the DSL router plugged directly in to the NID test jack outside.

    Having the exact same problems. I've had two pk5001z modems and they both drop my connection every 15ish mins. I have a family member who works for century link CMS so I've gotten quite a bit of help but no matter what I do to the settings it doesn't help.
    As another poster commented it does it on all devices but is most noticeable on gaming devices.
    I've switched back to my old modem/router for now which obviously fixed the problem but the old unit is a bit slower.

    Email received from Zyxel :

    We're looking into the problem in partnership with CenturyLink because this may require network related investigation. I would like to have the link of where you found other people having this same issue because this is something that has not been brought up to our attention, if there is any more information you can provide would also be helpful in trying to find a resolution to the issue.

    Thank you,

    I am still using the older 660 modem and have not had a problem yet. I keep checking the modem firmware update page but there is no update as of yet. I suggest if you are having this same problem as I had to email Zyxel and tell them your problem and reference them to this website. Good luck and if anything changes I will update this posting.

    The OP's issue was due to having interleaving added to his profile, which caused the extra latency.

    People with DHCP problems is a totally different issue.
