Most of our laptops are Japanese and most of it are Toshiba. The problems are:
1. Though not all the time, laptops just lose connection to the AP. When we inspect it, the WEP was lost or erased. When we type the WEP again, sometimes it will connect and sometimes not. So, we provide wired connection. The laptop will connect again to the AP after shutting it down for a longer time.
2. This one's strange, we have this toshiba laptop which connects to the AP just fine in its original location but when the owner transfers location, it just loses connection. The new location is a meeting room just a few meters away. Everybody in the room uses wireless connection and it's the only laptop which cannot connect.
These laptops are DHCP configured. When they lost connection, they cannot get an IP from the server. Is the problem an incompatibility between the Toshiba Japanese laptop and 350?
It may just be the combination here and the fact it is all on the Toshiba's is co incident
It is not only the ACU version that is important here
The NDIS and firmware
There are 3 parts of the software and if you upgrade one part then you should do all 3 in the past you had to each of them indiviually but in the latest version it will do them all at once for you by using a install wizard.
If you mix and match the versions of ACU NDIS and Firmware then you can get symptoms like you have described. It is best to rule this out first.
