Wanted: Any freelance IT guys willing to offer your services..?

Seriously though, are there no network geeks on here?

We are happy to pay. I would just like to use some through recommendation as the last guys we used were a nightmare.

sorry, skim read the rest, writing an essay here at the same time (bloody students).

It sounds to me like you're being throttled or something is being done to your line. Get in touch with your SP and ask them if anything's happening on their end. Although you should still get someone in to check your set up and see if any of the connections have deteriorated.

Can you switch the router for another to test that it's not the device?

run
netstat

maybe you have a virus eating your bandwidth

i'd also look into your DNS look ups, maybe the name resolution is slowing it down

Who is your line into the building provided by as they could have screwed up something at the Exchange (my mate did patching and circuit tests if a cable fell out they left it for the next guy to fix the fault)

Is the networking in the office all ok, can you print and copy stuff from the network? If tahts all ok then its your Cisco Box or the line or the bit in between.

Hmm.. doesn't look too bad but again I'm no expert on this shit. Ours is quite a bit quicker between hops here.
How many users do you have? Could someone be download large volumes and taking your bandwidth?
Do you have any bandwidth monitoring tools available?

I think you may be right.

I have just spoken with them and apparently in Dec and Jan our usage was up near 50 whatever bytes per month, we only used 10-15 whatever bytes per month previous to this.

They are having a look to see what may have caused this.

netstat

maybe you have a Wiesia trying to hunt down dodgy dancing videos on the net to remove them eating your bandwidth

I'm always right. Just that it might be days/months/years later ;)

I'd check all the machines on your network (inc. any laptops on your wifi) for latest antivirus definitions and scan 'em. If you have a packet sniffer/bandwidth monitor you could analyse heavy traffic and narrow it down to a single connection. If not, you migth have to go around and turn PCs on/off until you find the culprit.

Also, try asking users to stop doing any network instensive stuff like streaming for a while to see if it makes a diff. Depends on your work environment as to what you can get away with doing.

People actually working rather than watching porn might object :)

After hours ftw!

Actually, do you have laptops with roaming profiles stored on network server? If users have large profiles and they reconnect to the network you can see huge usage as the profiles resync from the server.

still 9 http sessions running.
maybe thats why its slow

Netstat will only show local traffic, not LAN traffic, nor WAN traffic.

You need to log onto the router.

Thanks, just trying to get the log in details now.

No idea what you are on about.

FYI - There are only 4 of us in the office.

.

you need to get onto router. you could also use wireshark to see where packets are being dropped etc.

Awesome thread... I can imagine V scampering around her office, pulling hair out while trying to fix the problem with hippy's awesome instructions... High drama... Gripping... ;]

I take it your ISP don't give you a net manager logon for looking at your upstream/downstream stats?

Do you know what contention ratio you have? Is it ADSL leased line?

Guaranteed bandwidth eh? :)

Have you tried a release/renew on one of your client PC's?

go to start, run, type cmd, at cursor type ipconfig /release

wait a few seconds for return

then type ipconfig /renew (note the space before the slash)

Name resolution aint the problem here - sustained download speeds are crap, name resolution issues would only either cause a download to fail or take a long while to start - they dont have any bearing on the actual throughput once a transfer has started.

As Hippy has mentioned this looks very much like a line problem - if it were the router having issues you would also (normally) expect greater latency and packet loss while it struggles to proccess packets. Latency looks fine so either someone/something is using up most of your bandwidth or your SP has throttled it/is having issues.

This thread is so dramatic - like an episode of ER. Love it :-)

fair enough!!
