What we have, is:Ed Cryer said:It could be a dodgy wifi connection.
Give us a full breakdown of your network; something like this, which is
1. Desktop computer with wireless modem-router; telephone broadband.
2. Two upstairs desktop computers with wifi dongles.
3. iPad with wifi.
P.S. There's also wifi interference to consider. My front doorbell used to
ring when a neighbour used a certain car key fob.
A wired LAN, with 3 desktop computers and a server (which is also a desktop
computer in fact, as it runs on XP Pro). All computers have static IP
addresses. There is a (non-wireless) router, connected to a glass fibre
modem. There is also an Access point, with a static IP address as well. All
are connected to a switch. All NIC's, cabling and the switch are 1 Gb. We
use TCP/IP, no Netbeui.
And there is the laptop, connected by Wifi to the Access point. The laptop
used to have a static address also, but since we use it on location as well,
it's configured to receive a DHCP address. In our situation it receives an
address from the router.
Is this useful to you?
You mention "a dodgy wifi connection".
I haven't thought of that, but I will connect the laptop to our LAN by wire.
See if that makes a difference. I'll come back on this one.
