PBX_TECH Posts: 8 Rating: (0)	Greetings, I need some advice on iPCF configuration. I have the following products: (1)SCALANCE W748-1 RJ45 6GK5748-1FC00-0AB0 (CLIENT MODE) with a W780 C-Plug installed and (1)SCALANCE W788-1 RJ45 6GK5788-1FC00-0AB0 (AP MODE) with a W780 C-Plug installed. I can ping back and fourth accross the WLAN just fine until I enable iPCF. Then the pings are sporadic back and forth. Any idea as to what I'm doing wrong? I currently have iPCF enabled on both devices. I've listed my event log enteries below. AP WLAN Authentication Log Restart Log Message 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' associated successfully 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' disassociated with reason (Too many retries) 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' associated successfully 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' disassociated with reason (Too many retries) 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' associated successfully 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' disassociated with reason (Too many retries) 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' associated successfully 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' disassociated with reason (Too many retries) 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' associated successfully 35 Client 00:1b:1b:80:a2:0a 'Guardian MFG CLIENT' disassociated with reason (Too many retries) Signal Strength between the two devices is 100%.

PBX_TECH Posts: 8 Rating: (0)	Ok I've resolved my connection problems by setting up security on the 'BASIC TAB' under security / WLAN TAB (On both devices.) However I'm still getting the log enteries from my previous entry. So, the question now is should I be worried about these enteries?

One thing that came into my mind because of your association - disassociation logs: What exactly do you mean with a signal strength of 100%? Normaly you give the strength of the signal as dBm? My guess on this topic is that you have a overmodulation and you can decrease the signal strength of your modules.

Good morning,

I was refering to the AP tab in my client device. It displays signal strength in [dbm] and [%]. I spread them out further this morning. And I still see the log file filling up. The current signal strength is 80% or -54dbm. Still waiting on a responce on my support request.

There is no other AP the clients can connect to? (your signal strength sounds OK) The AP has the whole time connection to the LAN and you have not configured "Force roaming on LAN interface down" or sth. like that?

When it's disabled everything works like a champ. There's only one client and one AP invloved. I'm not sure why my customer wants this enabled.

Depending on the further traffic on your network / WLAN ... the iPCF makes your communication deterministic (time slots for each iWLAN Client). I guess you know that and think with the little load on your network there should be no problem?

PBX_TECH Posts: 8 Rating: (0)	Ok, it looks like I resolved my issue. I have everything enabled that my customer requires including iPCF. Apparently there was some interference on the 2.4GHz band. I changed my frequency band to 5GHz and my client and AP Associated with one another (one time). I have yet to seethem becomeDisassociated. Always something simple.
