I play an online game and before break, everything worked fine.  There was no significant packet loss / latency issues with the application pre break; however, since returning from break, the application is constantly losing connection.  Did SIUE change anything with their network?  This is very frustrating.

I have a linksys router in my room that I have used pre break and post break.  The settings were not changed other than the WEP.  I called linksys and we determined that it is not the router's problem since we tested the application out while I was directly connected to SIUE's network and I still experienced this problem.

If there is ANYTHING I could do to change this, PLEASE LET ME KNOW.

Thank you very much,
Shaun

Yep.  They added a a ton more clients.  I bet the new freshmen are all taking advantage of the new speed they've been given and will soon accumulate enough porn to lay off the downloading for a while.

a ton more clients? Where exactly did they put them?  Before break approximately 3000 people lived on campus and after break approximately 3000 live on campus.  At 3am there's no other significant drain on bandwidth.  Why am I still downloading at 3-5k/sec with AIM disconnecting every 10 minutes, and low bandwidth sites like holdempoker.com keep booting me off for having a slow connection?  

And again nothing has changed in my computer setup.

I've seen the bandwith numbers, I can assure you that there is a  heck of a lot of traffic during the day and into the night untill about 5 or 6 am.

As far as I know nothing, that's what I saw last semester.  Its just heavy bandwith usage.

Does OIT happen run MRTG against the edge routers?  That might help users schedule their high bandwidth usage around peak times.  I like MRTG, it makes pretty pictures: http://motyka.org/mrtg/

I just ran a speed test just now.  I never got numbers like this last semester.  :-(

Results:

26 kbps DL speed
102 kbps upload speed

I'd be curious to see what the speed rating is elsewhere on campus.  Try the library or labs to see if QoS policies are throttling traffic to/from the reshalls.

First of all,  english please :-)

Secondly, I tested the computer labs in Prairie and they seem to be working fine.

This entire weekend, the internet has been horrible for me.  I've been experiencing alot of lag spikes.  It looks like things are going well and then BAM, huge lag spike. :-/

For example:

The ping on my VoIP program goes from a constant 41ish to pinging anywhere from 1000 up to 10000 lol.  Would they have changed anything within their networking?  Maybe a security measure or something?  I really do not kow that much about networking.

I took my laptop to a buddies room and plugged into his data jack and things worked fine.  I also tried the study lounge and things worked fine there also.  Could something be wrong with the data jack in my room?  Please help oh knowledgable CAOS people.  :-D

Its possible, but if your getting a connection its highly unlikely that your jack is causing slow speeds.  Most likely ( and I know i keep saying this sorry but,) its high bandwith usage from people who are on the same switch as you.  From what I understand they have been working on getting Fiber Optic line connected out in the dorms and CV, but I don't think its been finished yet.

Even during the weekend at say... around 3-4ish am?  :-?

Actually, it's quite possible it's the jack...  Your jack may have lost full duplex mode which then means it is possible for both the switch and the connected device to sense the wire and transmit at exactly the same time and result in a collision. Collisions can cause runts, FCS, and alignment errors due to the frame not being completely copied to the wire, which results in fragmented frames. It may be an issue with the cabling which causes marginal performance and high packet loss/collision counts.  Make sure your network adapter is set to auto-negotiate, as a computer set to full and a switch to half or vice-versa will also cause performance drops.  If you hook up to the other jack in your dorm room what happens? There's no guarantee your "buddy's" room is on the same switch as yours, nor that the other jack in your room is either, but it's more likely that way...

My network card is set to auto negotiate and I'm still experiencing the same problem while directly connected?  I just want to make sure that it's the jack for sure because I don't want to be charged 55 dollars for having the tech show up and nothing wrong with it.

Have you ran HiJackThis to make sure you don't have any spyware draining your connection?
