Ok short and sweet, I have a 2meg line with a 1meg account with AH, I do have a spare account that I use when the internet is being destroyed by youtube and phone updates, so when I see the internet getting slow I dial in the second account but I see crazy pings. How is this possible if im on a different network?

Here are some traceroutes when im on the dialed up account.

Code:
PS C:\WINDOWS\system32> ping bras.afrihost.com

Killing the wifi brings the pings back to normal.


Please help me with this guys, its really bothering me because it doesnt make any sense.

Best guess is you've got some device connected on wifi downloading stuff. On a 2 meg line thats enough to kill the pipe's latency. If the physical ADSL link is maxed then it doesn't matter what you dial in...its going to be kark.

Also...jirre man...that post is flippen incoherent as fk. You mention two accounts, don't even bother telling us what provider the second one is then post some arbitrary ping to only one of the two??? Oh and then randomly throw in a wifi comment. How do you expect anyone to deduce something meaningful from that? Garbage in, garbage out. But yeah try and disconnect wifi devices one by one till it goes away...maybe I deduced the answer correctly.

Also ping your router and see if the latency is on your internal network perhaps, could be router causing it for some reason

Did you even read?

If the router has a 1meg account then I should have 1meg of my own Internet via dial in.

Main account is AH and second is IS

Try what I said - disconnect wifi devices one by one. You'll see I'm right - one of them is downloading heavily - heavily enough to fk with your latency on the physical line, but not 100% of the time which will get you inconsistent patterns exactly like you're seeing - high latency with random OK ones.

Thats assuming the baseline stats are fine - can't comment on that because well you didn't post them. So we might be looking at a combination of exchange congestion and a wifi device downloading for all we know.

Gut feeling - and again guessing (since flying blind) I'd say 50% chance that you're looking at two problems here: semi-congested exchange *and* some wifi device downloading. I assume you took those measurements roughly at when you posted your OP...09:43 PM. Well thats roughly the time when semi-congested exchanges sht themselves.

hmm...just realised the above is an example of very passive-aggressive troubleshoot. Interesting.

The device on wifi can download as much as is wants to but it cant affect the dial up account as the wifi is limited to 1meg whereas the dial in account has access to 2meg.

I think ive narrowed it down to upload, some device is doing some sort of upload.

I didnt post line stats because i know its not that and i know how to read it.

Hahaha. You're very wrong about that. Wish I could put money on this...

Latency gets fk'd even if you run two 1meg accounts on a 2meg line. Grade 1 maths suggests it should work but in the real world it doesn't.

The fact that you think I'm asking for line stats pretty much says it all...

I actually wanted a trace during a time when your internet is fine according to you (i.e. "baseline"). As I said - I suspect a semi-congested exchange. This is something that you'll never be able to see in line stats (physically not possible).

The lowest result you've got in the (*ahm*) limited info available is 83ms. If this is a device downloading flat out @1meg account on a 2 meg line then I would have expected something closer to 20-40ms as the lowest value for a local IS server on IS account because routers tend to interleave downloads if devices compete for limited capacity. Or put differently if two devices compete for capacity then you should see sporadically good latency. Which you are (the 83ms)....but its not good enough - there is still an anomaly there.

That combined with the overall higher than expected latencies (way too many results north of 1000ms. I'd expect 500-800 mostly) still suggests to me that we're looking at two issues here.

Depends, you can run 2x100KB/s downloads no problem but when it comes to gaming there has to be some limit on the side you are playing games online, online gaming needs some down and upload speed otherwise you lag.

I want to test a theory, but I really don't have the time to test it (my setup is too complex to change it to just replicate this, it will take a few hours just to get it "normal", and then it will take a few hours to get it to where it needs to be again).

I've had the same issue half and half a while ago. I have two accounts as well, and neither would work properly. Issue at the end of the day was upload. Devices would upload photos to the Google cloud platform, saturating the upload, causing heavy ping spikes and packet loss. Do yourself a favour, monitor your upload bandwidth, and make sure one account isn't saturating the upload.

what is your upstream sync rate and what are you data packages upstream.

the 2x 1mbps might fit nicely into 2mbps, but does the upstream fit nicely too?
