Topic # 31683 26-Mar-2009 20:36

Just wondering if anyone had had a similar experience:

speed tests across several machines, using several different browsers within our wireless and wired network at home are consistent: speeds around 4Mb down, 100k up. Two OS's, four different machines.

problem is that whilst the connection is ostensibly running at what passes for full rate here, experience is saying it's throughput is slow.

Using several different smtp servers for the domains I use, those not using the smtp.ihug.co.nz port are dropping and taking two tries to send

Secure connections [Google mail/docs/igoogle] and facebook connections [I know, how puerile, but there's four teenagers here] and imap connections to gmail keep getting dropped or take two attempts to connect.

I've swapped out filters

I've restarted routers

I've tried hardwiring wireless computers

I've tried wirelessing normally hardwired computers

Deleting cookies for FaceBook allowed initial access, but then subsequent efforts failed again.

Anyone have any ideas?

varies between 1.8Mb and 3.8mb down and 100k up. Fairly normal for distance from exchange,

what are the actual stats from the router?

done some tracerts/pings to those servers and others to check for packetloss?

have you tried another router?

Looks like your modem could be disconnecting

Does the DSL light on the modem go off or flash when your having internet problems and does this happen on all the computers in the house?

Also as dan said it would be good if you copy and paste the actual stats from the modem

Do a tracert to some of the problematic websites and post the results here.

Start -> Run -> Cmd

Tracert <problematic website> (without the <>'s)

After it's complete left click in top left-hand corner of the window, and go edit -> mark then select the text with your mouse and finally hit enter/return to copy it to the clipboard, then paste here.

Should look similar to this (except addresses will differ):

Are you on the vodafone red network? I saw a thread talking about similar issues on nznog, the solution was to reduce the mtu from 1500 to 1492.

first, your router is pinging quite high for something on a LAN, usually it would be around 1ms, but yours went from 10 to 20 to 2ms

your next hop is a massive 800 to 900ms, should be less than 10% of that

FYI is is my first few hops to facebook for you to compare

Tracing route to www.facebook.com [69.63.180.15]
over a maximum of 30 hops:

1    <1 ms    <1 ms    <1 ms 192.168.1.11
2    23 ms    22 ms    22 ms lo1.ras1.nct.orcon.net.nz [60.234.8.201]
3    22 ms    23 ms    21 ms ge-0-0-4-0.cre1.nct.orcon.net.nz [121.98.9.1]
4    22 ms    25 ms    24 ms ae1-0.cre2.nct.orcon.net.nz [121.98.9.14]
5    24 ms    25 ms    22 ms ge-1-3-0-0.bdr2.nct.orcon.net.nz [121.98.9.38]

I would try another DSL router to see if that is the issue ..
