[dba-Tech] Vista looses frequently LAN connection and can'treconnect via DHCP

Clients like zero cost. ;-)

There are Wi-Fi routers/hubs and there are top of the line systems. I have
found that performance, in many case parallels the price. I have clients
with some very nice Cisco Wi-Fi hubs/switches and they are rock solid. (They
have some great software and when directly connected to a monitoring
computer, you can watch performance graphs, see the strength of the
connection signal, watch connection strength diminish as the remote moves
further away from the receiver etc...)

I have found that some inexpensive laptop computers do not connect and stay
connected as reliability as some of the better brands... (I tend to
recommend Toshiba and higher end Dell and IBM units) 

On the other hand, my $8.00 Wi-Fi hubs works great... for about 8 meters.

Hi Jim

Yes, we will definitely look for a replacement for the DHCP service. Maybe
leave the router and fire up the DHCP server of their Windows Server. How
about that? We don't use this setup much but why not if that could solve the
issue at nearly zero cost.

The router is not with Wi-Fi. That is handled with a Wi-Fi bridge.

Hi Gustav:

As the article(s) says it is an issue between older router equipment and
Vista. I have a client who has a couple of laptops that use Vista and an
older (3 years) wireless router. As soon as both of them try to connect
wirelessly connection start dropping.

I took the easy way out by just cabling both the offices and suggested that
they may look at a new Wi-Fi router in the future. Now only if an individual
is wandering around the warehouse doing inventory do they use wireless.

Hi all

Anyone having trouble with this?
We have a client where Vista client laptops frequently pops off and on the
wired LAN. Sometimes the new DHCP request fails and the pc stays
disconnected. Later you can reestablish connection.

We located this:

http://en.kioskea.net/forum/affich-45038-internet-disconnects-when-2nd-user-

is-on#p45086 

with links to these:

http://support.microsoft.com/kb/928233 

and as the client often use sleep mode for the laptops:

http://support.microsoft.com/kb/933872 
http://support.microsoft.com/kb/928152 

The router is an older Zywall so the KB article may apply  haven't check
that yet - but I wonder if anyone have some other ideas?
