After hours of testing and configuring I can say it’s not the same issue as discussed in the link above. I have the same problem as mentioned at the beginning. Our set-up: We have Mac clients and Cisco networking equipment. We would like to use the WAP4410 (220.127.116.11) as our access point. However, 10-20 minutes after connecting to the access point, the connection doesn’t work anymore. It happens randomly and not only during large file transfers. It also happens when I’m not even using the computer. After disabling and enabling the wireless interface on the client I get back the connection (for the next 10-20 minutes). I not only tried to change all different settings on the access point (channel, encryption mode, ssid, channel bandwidth, ...) but I also changed settings on the Mac (disable IPv6) but it’s still not working. Of course I also tried older firmwares. It’s really annoying. Thanks for your help.

Hi everyone I used to work with Cisco routers and switches for many years in my previous position as a network opperator. Now I changed the company and I'm in charge for IT security. The organization is small and has about 20-25 users. The entire infrastructure is based on Mac, including the Server. At the moment we only use personal firewalls and don't have any UTM appliances installed. However, the business requirements changed and we weould like to set up VPN for some of our employees. I've made some research and found that there are several products which could help us to build a more secure network. On one hand, the SA540 from Cisco is quite interesting since it has good performance and is a well known brand. On the other hand, other products such as safe@office from checkpoint or prosecure from netgear are interessting as well and are probably a little bit cheaper. Anyway, I have some questions about the SA520 and SA540 and hope that someone can answer it. First of all, I wanted to know if you think these appliances are good enough for the size of our company. I didn't find any information about concurrent users in the specs. Second, I would like to know more about VPN. In the SA540 there are 50 seats included, what does that mean? And what type of VPN Client do we need? Are the clients (software) included in the product and does it work for Mac OS X? I'm looking forward to your feedback. Thanks a lot! Cheers, Daniel
