Cable users: ping your default gateway please...

[Trente]

Hey,

I'd like your help in figuring out a problem with my internet connection. Just post 25 ping results to your default gateway so I can compare with mine...

TIA!

 

[nsafreak]

I'm curious as to what the problem is that you're experiencing. Have DSL so I can't help with the ping (it's a nice low 20) but just curious.

 

[Trente]

My pings are very jumpy. say, they may reach 30ms sometimes then fall down to 6ms or 7ms. I want to see if this is happening to others out there.

 

[nsafreak]

Is this the ping to your gateway or just pings to various servers on the internet? If it's the gateway it could be the number of people on your network at peak times I suppose.

Gateway. pinging servers is "overkill" (they are far away and require you to go through many hops) so you can't notice this issue by doing that. on DSL it does not happen AFAIK, but every Cable user I ran into has this issue. Is that a limitation of the cable technology itself, then?

Hopefuly, the results of ATOT users would help me figure this out...

Thanks mobobuff. you could have done copy&paste like I did:

time=6ms
time=42ms
time=17ms
time=8ms
time=5ms
time=15ms
time=5ms
time=6ms
time=7ms
time=8ms
time=9ms
time=8ms
time=5ms
time=6ms
time=6ms
time=7ms
time=6ms
time=7ms
time=7ms
time=6ms
time=6ms
time=5ms
time=7ms
time=44ms
time=37ms

It seems your's are a bit jumpy as well...

I did so again to make sure I get credible results:

time=8ms
time=8ms
time=6ms
time=19ms
time=4ms
time=8ms
time=5ms
time=6ms
time=6ms
time=6ms
time=8ms

The high pings are because of downloads

What's with you people deleting/blocking the IP?

It's not like it's a secret or anything.

Wow, my pings seem to be almost perfect. Definately not jumpy. It is certainly not a "limitation of the cable technology".

I tried copying, but it was weird, my console wouldn't let me.

Right click, go to Mark? You should then be able to select and copy as normal.

 

[paruhd0x]

I usually just click select all then select what I want, right click = copy to clipboard

 

[Trente]

Eli has got no issues!

I'm confused...

According to howstuffworks:

If you are one of the first users to connect to the Internet through a particular cable channel, then you may have nearly the entire bandwidth of the channel available for your use. As new users, especially heavy-access users, are connected to the channel, you will have to share that bandwidth, and may see your performance degrade as a result. It is possible that, in times of heavy usage with many connected users, performance will be far below the theoretical maximums. The good news is that this particular performance issue can be resolved by the cable company adding a new channel and splitting the base of users.

Could this random shift in pings results be an issue with the cable technology itself?

I think nsafreak has a point here:

If it's the gateway it could be the number of people on your network at peak times I suppose.

No wonder that DSL has no such issue, since you are not affected by other users' activity...
It is to be noted though, that Cable technology compensates on this by providing generally lower pings.


Eli: Are there any people on you neighbourhood conencted via Cable? Could it be that no one else is using it ATM?

You wouldn't believe how much I feel like a n00b right now.

Eli: Are there any people on you neighbourhood conencted via Cable? Could it be that no one else is using it ATM?

I have no idea how many people in my neighborhood have cable, lol....

I've always heard that they were very generous when creating the cable infrastructure here in Portland. They were sure not to let nodes get overloaded.

Ping spikes to the gateway could be caused by a bad connection in your local lines.

When I first got my cable installed, I was getting horrible packet loss and ping spikes. I had several techs out, etc etc.. could never figure it out. It was this way for months. Dialup was overall faster. Then one day, decided to use a flash light while working with the cable jack(which was back in a dark corner). Much to my surprise, I noticed that the whole thing was green with corrosion.

I took a wire brush to it, made it all nice and shiney.. boom, problem solved. I bitched and got 2 free months of service out of it.

Make sure everything is nice and tight. If everything seems fine, it could be because the gateway is slightly overloaded. It's not peak usage time, though.

Are you getting your full rated bandwidth?

 

[Trente]

Yeah, I get full bandwidth.

Well, thats what I would try first. Take a wire brush/steelwool/fine sandpaper to your cable jacks, both inside and any that are outside. When you put everything back together make sure it's all snug.

Hell, my cable connection is split 3 times before it gets to my cable modem. One is a high quality grounded splitter, the other two are just cheapo radio shack splitters tho. I'd say you're definately getting signal loss somewhere, assuming your gateway itself isn't at fault.

Does it get worse during peak times(around 6PM)?

Edit: If this thread is still alive later on, when I get home from work, I'll try again cause that'll be during 'peak' times.

 

[Trente]

Well, here we have a protected box that can only be opened by the cable guy.

I'll check it later today/tomorrow and see if this gets worse during peak hours, will post resutls...

BTW, I also have a splitter in the house that is not needed now. should I try bypassing it by myself?

BTW no.2, take a look at this: http://img1.tapuz.co.il/forums/38556910.jpg Do these figures seem right?
