Extremely slow network connection / internet

[Guest]

I have installed Vista RC1 5600 on a few machines, but have a problem (on all
machines) where some sites are either incredibly slow or just seem to grind
to a halt and not load.

Some sites are ok e.g google, but most others including microsoft.com seem
to load a bit of the page, page title, but then stop. Iv'e tried using IE7
and also FireFox, but get the same problem.

Under internet options> lan settings, I do not have 'Automatically detect
settings' ticked. (though it is the same with it ticked) and I have also
tried turning off Phishing filter, protected mode and things like activex and
java.

The same sites open fine with IE7 or Firefox under windows XP. It is not
just internet pages either as downloads on Vista seem to be the same, e.g.
attempting to download firefox will gert about 20k, then stop. (on a 2mb line
-fine on XP)

I'm going to download RC1 5728, but I had the same problem with 5536 so not
holding my breath...

Any ideas?

Cheers,
Alastair

Hi,

I have exactly the same problem as you. But to try and throw some more
light on the problem i contacted our hosting company as it seems that all the
problem sites that i have seen are on the same hosting company (titan
internet).

They sent me a util that was supposed to trace a route back to them, sort of
a mixture between tracert and ping. That seemed to show there was a big
routing issue.

To cause a further issue, i can't get email from that server either or use
other browsers such as Firefox and Netscape. I personally think it is an
issue with the protocol stack, but am investigating that now.

I'll feed back if i find any info on it

Disable IPv6.

That worked a treat... no more problem pages now.

Cheers for that

Hello there ,
How do you get this auto TCP disabled ?

We tried running "netsh interface tcp set global autotuninglevel=disabled"
on the command prompt on Vista.

We get the following message :
"Set global command failed on IPv4 The requested operation requires elevation.

Is someone aware what is happening here ? Why is this command failing.

We are logged in as Administrators

This has to be run as the real administrator. If you go to accesoiries in
there you have the CMD prompt right click and select run as admiistrator, in
there type the command line again, now it works.

My first post, but I found the above posts very useful so I thought I
should last least thanks people and also add what fixed the problem for
me:

As some others have experienced, I to had painfully slows network
activity not just on the local network but also internet, generally all
traffic. I applied the hotfix 931770, and the autotuninglevel=disabled
hack but still my network connection was unusable so I uninstalled the
hotfix and set autotuninglevel back to normal. My next approach so to
look at the network card drivers, so I uninstalled my Realtek 8139/810x
drivers selecting to delete them driver. Windows found the card and
installed the driver back automatically which was odd as I selected to
delete the driver. However, to my surprise my network speed was restored
back to its full potential. With the network back I decided to perform a
Windows update which showed an updated RealTek driver available, I
installed the update and guess what? .....yes the network sh& itself and
went back down to KB speed I’ve been plagued with for the past month or
so. A simple driver roll back soon had that problem sorted. There was
still one problem and that was the old 'Calculating time....' issue when
transferring large files, which was soon sorted by reapplying hotfox
931770.

So if you have a RealTek 8139/810x network card and slow network issues
I suggest sticking with the Vista supplied driver and not the newer
windows update driver, it solved all my problem for me anyway. Thank.

Thanks for sharing that. In general, I advise not using drivers provided
through Windows update. Over the years, I've seen frequent problems with
them. It's best to go to the manufacturers site if there is a need to
update.

FYI. I had the same problem with the 6.103... Realtek 8139 driver update and
since my laptop with the 5.640... driver didn't have the problem, found the
same solution.

Realtek (www.realtek.com/downloads) now has a 6.104... driver which also
solves the problem.

I have a similar problem, but I'm not sure it is the same. My internet
connection seems to suddenly go dead after working OK for some time after
boot-up. I have to re-boot several times a day to reset whatever is
happening. I have noticed that the pop-up message when I mouse over the
network connection icon in the tray says "Local and Internet" when things are
working, and it says "Local only" when the internet suddenly stops working.
Some web sites seem to invoke this problem more than others, but not every
time. For example, I have been able to view my Hotmail email, but I can
rarely get through the log-in on the Yahoo email web site.

Setup: Brand new desktop (Dell Inspiron) with cable internet connection. No
wireless router - I connect to the cable modem directly with an ethernet
cable. The PC is running Windows Vista home edition, and the network card is
from Nvidia.

History: This problem has been present right out of the box. I have updated
the NIC driver (same result). I have tried to roll the driver back to an old
version, but couldn't find one to download that is older than the one that
the PC shipped with. From the NIC properties, I tried disabling QoS Packet
Scheduler, Ipv 6, and the topology items (same result). I also tried the
"netsh interface tcp set global autotuninglevel=disabled" solution (same
result).

If anyone can help with this problem I would greatly appreciate it.
Thanks!

Tyr to disable IPv6 first. if that doesn't fix the problem. Check this link.
Please post back with the result.
