Why are you using the crossover cable at all now that you're using a
hub?

Oh font, I humbly beg for your assistance in sorting out my home network.

Up till this week I had my computer connected to my wife's computer by means
of a cross-over cable, running a little TCP/IP network with ICS.

Earlier this week my employers sent me a lap-top, which I'd like to use from
home as well.

So, I ran the cross-over cable to a 5 port hub, wired my wife's computer off
that, stuck a wireless access point in another port and connected the
lap-top via that.

My wife's computer still works fine, but everything network related on the
lap-top (Internet, file sharing, printer sharing, etc.) seems very slow.
It's working in that I can see the other computers on the network, connect
to them, ping them, blah, blah, so there's nothing terribly wrong.

Indeed the network has short bursts where it seems to go at full speed and
then slows to a crawl, for no apparent reason. There are also strange
things such as, last night, I was running a DOS shell on the lap-top and
mapped the Z drive to my desk-top PC's shared drive.

Trying to copy two (both 2Kb) files from D: to Z: just kept timing out, but
when I changed to drive Z it copied a 6.5MB file to drive D like that <snaps
fingers>.

When I pinged my desktop from the laptop the first two pings took 1ms, the
third timed out and the fourth was back to 1ms. If I do a NET VIEW of my
machine it pops straight up, if I do a NET USE it takes forever.

Things I've ruled out:

It's not the wireless connection, because it's exactly the same situation if
I physically wire the lap-top to the hub.

It's not the cross-over cable or the hub, because my wife's computer is
working fine.

It's not a firewall issue, because I've tried turning off all firewalls that
are involved.

It's not an OS or software problem on the lap-top, because I took it round
to Eddie's and it connected fine to his wireless network and worked like a
charm.

Anybody got any brilliant ideas for stuff that I might have overlooked?

The flaky 5 port hub.

Try moving things to other ports...

 

Bin the hub, buy a switch.

Soy.

 

Done that, to no noticeable effect.

Because my computer is upstairs, while my wife's computer (and the hub and
the wireless access point) are downstairs and the long cable that was
connecting my computer to my wife's is a pain to replace because it is run
under carpets and tacked to the wall and things.

Given that my wife's computer is fine there doesn't seem to be any value, at
this stage, in changing the cross-over cable.

Just realised you don't mention internet connectivity itself is bad for
the whole network, just microsoft networking type things (including ICS)
are taking ages to connect..

So, it's probably a netbios name resolution on the home LAN issue.

Put the IP details of all the machines on your network into the LMhosts
file on the laptop, it'll improve lookups for netbios comms without
having to mess with any other settings, or fucking up the machine for
use in the office. The laptop has probably been configured to use DNS
lookup first (as would often be normal on a corporate LAN).

HTH.

 

please, please,
can I be the first to say

thank ewe

 

Cannibal.

 

Yeah, right.

 

Butbutbut - if you're now plugging computers into the hubs, there
should be no crossover cables in use at all! I can't understand how
it works for a moment!

Auto-switching hub?

 

Theres the problem. This shouldn't work at all, although some hubs/nics
try to make the best of a bad situation. Dont use crossover cables with
hubs or switches. Either get a new cable or a dongly thing to uncross it.

 

All you're network cables need to be straight through with a hub, you
can get little converters that will change this at the socket if you
want, I got some here

Have you tried turning it off and on again? You can do this just using the
keyboard.

 

Manual switching hub.

And, yes, I did press the switch.

Some hubs/switches have autosensing ports. Mine does this, I can use
a crossover or normal cable in any port and it'll work out what it is
and what it's connected to and re-configure the port as appropriate.

 

That isn't the problem - my wife's computer is also off the hub, so if the
cross-over cable wasn't working then her computer wouldn't work either.

As it happens I've unplugged the cross-over cable, moved the hub and the
wireless access point upstairs, plugged them all into my PC and now nothing
works. The lap-top can't even detect the access point, even though all of
the little lights are on and everything.

Bugger.

Did you set up the laptop for your home network correctly. Does Mr Laptop
still think its connected to the works network. Is it therefore searching
for things on the network and slowing itself down. You must ask yourself
these questions and meny others.

Goddnight I'm going home...
