Hi
Yeah, and there are Millions of users that their Computers get Hacked on a
daily basis, and then used as "Zombies'" to propagate Viruses and Malwares
to others.
If you need the java download the runtime file and install indecently.

there must be millions, literally, of home users such as myself that have
their PC directly connected to the cable modem provided by, and installed
by,
the cable company.........

back to the issue; can't seem to download the java.com recommended to
have....hangs on that task.....both IE8 and Firefox.....and yet can browse
some sites fine. Definitely never streaming media or anything with lots
of
activity......

but the XP Network Diagostics process will clear it up - but not a
permanent fix as it will still hang on the same situations.......

Hi
First it is a big mistake to connect directly to a modem even if you have
one computer.
Especially on Cable Internet that works thta employ a topology of many
users
connected together on the same Node.
Get yourself a Router that are very inexpensive (Example,
http://www.newegg.com/Product/Produc...-033-_-Product )
..
The MTU on Cable Internet should be 1500.
In case you get a router read this, http://www.ezlan.net/broadband.html

sorry for leaving out info; am connected directly to a TimeWarner
cable
modem.

the firewall/antivirus are off just as a trouble shooting need....

my MTU field was blank - so I put in 1300.

one more thing - downloads such as a file attachment to an email seem
to
work....at least so far I've done a couple upto 2M and they've worked
ok...

it is the streaming media that really never works at all or at least
not
for
very long....I went to youtube and tried it after the 1300 MTU entry
and
the
download to fireup the video went again into hang mode of never
ending....of
course I never let it run forever to see if it ever completes....

in the dslreports...mine were not all at default like their example;
mine
a
scale: yes
timestamp: no
select acks: yes
path mtu disc yes
black hole: no
max dup: 2
ttl: 64

and then went to http://www.dslreports.com/tweaks and saw my java
applets
weren't working....so haven't resolved that point....

hi folks,

have xp/sp3 with 768Ram & 400meghz...have turned off windows
firewall and do not have antivirus at the moment (trying to rule
them out)...

both IE8 (set to all default values) and Firefox will hang during
any significant download. Streaming video in example always
hangs....but so will just some web pages that are particularly
busy.....browses fine for most other sites for awhile but will
also sometimes just hang.

when can't reach a site - xp will pop up offer network diagnostic
feature - - and that will clear up the problem (though a download
has to restart from beginning and still will never complete...

I ruled out IE8 by trying Firefox....and I don't really think it
is a virus........have looked at the logs offered during the
Network Diagnostics and I see a line about semaphore timeout...

anyone knowing about this? would really appreciate some help on
this....


There are a lot of details lacking, but to me the symptoms point to a
MTU value being set too high. The absolute max MTU is 1500 but you
must subtract bytes for headers. Even more bytes must be subtracted
for DSL, and yet more must be subtracted for VPN.

Setting the value too high will force the network to fracture packets
that are too big. This works for a while but soon things get
scrambled
and everything halts. This is why this problem is most apparent when
doing downloads.

To rule this out as your problem, change the MTU to an extremely
conservative value of 1300 (assuming you aren't using a dial-up
connection) with the program "DrTCP" available at:
http://www.dslreports.com/drtcp
Run it and set MaxMTU to 1300. Reboot machine. If you problem goes
away, then this is your problem. Otherwise you've ruled this out.

You might try the "Tweak Tool" as well:
