Hi everyone, i have a weird problem and i hope you can help me guys!!
I have just migrate a Symbol-based autonomous wireless network to a Cisco Controller-based environment and everything apparently was working fine. However a few weeks later the installation was over, my customer reported they can't access to a server's shared folder.
This WLAN environment is installed in a warehouse and it is meant to support two different types of users: Regular Lap Top users and Motorola-Symbol Handhels. There are two SSIDs with static security methods (one with WPA+PSK and the other with static WEP key), Handhelds are joined to the SSID with static WEP key. So, here's the deal, this handhelds can join the network without any connectivity issues, roaming, signal strenght, etc. They can also ping everywhere. The problem is that when they need to access a server's shared folder and download files, handhelds displays a bad network path error message. If you do the same with a lap top, you can access the server´s folder with no problems. The handheld model is a Motorola-Symbol 9090 with Windows CE operating system version 5.0. Cisco infraestructure is as follows: WLC5508 running OS version 22.214.171.124 and AIR-LAP1142N-N-K9 series Access Points. In adition, i made a lab back in the office, and reproduce the problem. I tested with an autonomous AP same model and I can actually access a server's folder with no issue but int the very moment i test with a controller-based network i get the same result. I have made several changes in both, handheld and controller, based on a Cisco document for Motorola-Symbol and Cisco best practices. I also have placed a sniffer on my network but I can´t see any traffic when joined throught controller's WLAN. I placed it in the link between WLC and switch and between the switch and the Cisco AP.
Hi Amjad, I issued the command config network broadcast enable and this apparently solved the problem, I don't know if this will have further consecuences, please let me know if there's something and thank you very much for your assistance
No, I don't Amjad. When I was troubleshooting I discovered that, when with an autonomous AP, the only traffic was Netbios and I had access to server's folder. On the other hand, when I was testing with lightweight infraestructure, I didn't see any traffic at all. So, I know Netbios is broadcast traffic and -after your answer- when I was reviewing a document for multicast I saw that broadcast must be enabled before enabling Multicast. So I decide to just enable broadcast and see how it works. by the way, I think this is a weird behavior because both, Handheld and Server are on the same subnet...
