We have a client who is having recurring problems maintaining a solid connection to a wireless network. The network consists of twenty-four hard-wired users on a LAN, of which eight also connect to the internet via a wireless router. The hard-wired lan is in place to run a proprietary software package and has no need for internet connectivity. The hard-wired NICS are therefore LAN only. The eight users who are on the wireless network are using the wireless for internet because in order to give them hard-wire access to the internet everyone in the building would have to have it, and management doesn't want this since most need only the proprietary software. The eight, therefore, are the only ones who have both a hard-wire and a wireless connection.
The problem is that IE seems to have trouble connecting to the wireless network whenever the LAN is present. If we disconnect the LAN line from each pc, the wireless adapter connects beautifully with no problems. When we reconnect the LAN line so that the proprietary software is available, the wireless connection is continually dropped (about 50% of the time)
How can we get the wireless and wired adapters to work together smoothly?
