internet speed problems since installing xp

[Gordon Abbot]

Two computers (one 98se and one xp) both connected through a hub to a
cable modem thence to the Internet.

Before I installed xp my 98se computer Internet speed was exactly like
the other 98se computer. Since installing xp, it has dropped 1/3. I have
tried different hub ports and still slow.

If I connect it directly to the modem, I get the same speed as the 98se
computer. So the hub seems to be the issue, but only for the xp computer.

I have tried to repair the connection and no change. However, at the end
of the repair I get a "cannot clear the DNS cache", so I got the
directions on the Internet on how to clear the cache "ipconfig
/flushdns" from the command prompt and no change.

I shut the hub and the modem down, restarted and rebooted and no change.
I ran anti virus, anti spy ware and anti Trojan programs (AVG, Ad aware,
spybot, and A2) and my system is clean. I uninstalled the network card
and let windows reinstall it and no change. I shut down my firewall
(zonealarm) and no change.

I ran TCP view to see if there was any other activity, and there is
none, just the normal windows and browser functions.

During the installation of xp it became a bit confusing when I was
setting up the Internet connection, so something may have gone bad
there, probably in the network section. There was some info on what
computer did what and I may have done something there to cause the
problem in relation to the hub.

Otherwise everything works fine, it is just the Internet speed is much
slower on the xp computer than the 98se.

Any help appreciated, especially how to remove all network and Internet
settings and set up the Internet only. I do not need any home network,
only the Internet connection.

Gordon,

Could you do us a favor so we know what your configurations are set at? In
XP, open a command prompt (Start > Run > type "cmd" in Open: box > OK) and
type this command without the quotes: "netsh interface ip show config" and
"ipconfig" (or you could just do an "ipconfig /all"). Please post your
results here. The fact that "ipconfig /flushdns" failed is not good -
generally speaking, you should be able to flush that cache without a problem.
It could mean that your network card is unsupported, but more likely it
means that it is just improperly configured or has the wrong device driver
(though this is unlikely because it can connect to the Internet.) If
everything works properly up to this point, you can post your results and
wait for a response. If it fails, try issuing this command at a command
prompt: "netsh interface ip reset". This should reset your TCP/IP
configuration to a clean configuration, assuming the interface is functional.

Done, also I did clear the DNS cache, it is just that it made no
difference. Also, after I cleared it and ran the repair again, I still
got the DNS cache could not be cleared.

Gordon, if you only have 2 pc's, you don't NEED a hub for the cable modem.
Direct-connect the modem to one card on the "master"pc, connect a second Lan
card via crossover (not patch) cable to 2nd pc.
This gives both networking and shared internet access, with no hardware,
therefore no conflicts, for 2 pc's.
Works for me! Only minor drawback is - both pc's need to be booted up if
2nd pc needs the access (the master works fine on its own)., but, both can
share the access simultaneously. Both pc's happen to be XP, both speeds
identical.
Minimal cost - less than £10 incl postage for both Lan card and 3m cable in
UK.

Whilst this does not solve the cache-flush issue, it does address
connectivity - it simplifies the dataflow path by removing the hub and USB
issues.

Sincerely, Len

Well, for what it's worth, I have never seen a problem with a hub as far as
XP compatibility goes. I suppose in theory, it's possible, but also in
theory, a hub should be so far separated (OSI model) from the operating
system that it shouldn't make a difference. I would initially venture a
proposal that two strange things are happening: 1) it appears you have IPv6
enabled. Unless your ISP has asked you to do this specifically, I would
immediately eliminate that from your system. If for any reason XP is trying
to communicate via IPv6 (fe80::2a0:ccff:fe7a:85af%f) first and failing over
to IPv4 (207.5.199.204), that could explain the difference in speed. And
since your Windows 98 station works fine and doesn't support IPv6, I would
guess that is the most likely solution. The other thing that is strange is
the presence of the multiple Pseudo-Interfaces, which are also related to
IPv6. To be honest, I really don't know much about IPv6 or its inner
workings at this point. It isn't in widespread enough use for me to work
with it on a daily basis, but I have serious reservations about whether you
would need it at all at this point.

I would recommend, first of all, eliminating IPv6 from your system unless
you have a specific reason for keeping it. Secondly, I would recommend
temporarily disabling your pseudo-interfaces (if removing IPv6 doesn't remove
them for you) and observing whether or not that makes a difference. (You can
do this in Device Manager, Start > Run > devmgmt.msc > OK.) If you can get
into your network connections applet from the control panel, you can see the
binding order of your adapters by going to Advanced > Advanced Settings on
the menu.

Here's a place to start:

Forgive me if some of my instructions are overly basic - you seem like a
fairly adept guy - I just don't want to have to post any more than necessary.

Let us know what happens!

Mark,

Thanks for your help. This am as I was writing the answer to your post
my modem died. The "cable guy" cam by and found problems in the line up
the street but the next one that came found that the modem was
borderline. All the tests the company did on it did not show that it was
bad, since it was teetering on the edge. Got an new modem and all is
working fine even with the hub.

For some reason, when the modem was connected to the hub, its, not xps,
efficiency dropped by half, but only with xp and not with 98se. But the
overall speed of 98se with everything was actually about 1meg lower than
it is now. I was told that my system was about 1.5 mbits as a norm, but
it is actually about 2-2.7mbits with the new modem.

I am sure with a new router (just purchased) I will be up to best speed.

I did do all that you suggested and, even with the old modem, got some
improvement, so with the new modem I will be at peak efficiency, thanks
to you. Learned a lot about my network and used all the help links you
gave me.

One interesting thing is I6Pv is beta as noted by MS. I can assume it
came in with SP2, but have no idea how it decided to install itself. It
is gone now. I got a small speed boost with it gone.

I am one of those few who has no problem when my computer acts up, since
I enjoy working on it, ever since the days of dos when I read my
floppies and changed the hex with my Atari. That was when a spreadsheet
program could fit on a 5" floppy.

I also note quite a few names from back at the gateway newsgroup as well
as the 98 group on this group. This is a very helpful newsgroup with a
surprisingly low level of heat (although that it interesting from time
to time).

Again, thanks.
