Hello everyone, I've been trying to track down a very stubborn problem that I've been having at 2
sites now; the client computers show repeated syslog entries of
Event 4201 - The system detected that the [XXX adapter name] was connected to the network, and has initiated normal operation over the network adapter. Each entry coincides with a brief network interruption lasting a few seconds. These interruptions and event log entries happen at seemingly random times, and do not coincide with each on various machines. They might happen once every minute or so for a few minutes, then nothing for an hour or more.
The AP in question is an AIR-AP1242G A-K9 V03 running F/W ver. 12.4(21a)JA1. (same at both sites) We are running WPA2 PSK for security, with no further measures (ie. MAC address filtering).
Client adapter cards at site one are a mixture of Cisco SMB WMP200 and Linksys WMP54G, both on latest drivers. Clients are running XP Pro SP3 on a couple generations of Advantech industrial PCs.
Clients at site two are all Dell optiplex 380 running XP Pro SP3 and all are using Linksys WMP54G ver. 4.1 adapters on Linksys' latest drivers.
I have seen this issue at both sites, but is most pronounced and best documented on the systems at site two.
I have a Metageek Wi-Spy that I've used to monitor for any crazy RF noise (nothing notable found) at both sites.
I would love to get this issue resolved as it has been an ongoing problem and a very difficult one to diagnose. Any assistance would be greatly appreciated.
Thanks in advance
