Wireless access point crash

Posted on 2012-09-11

I work part time for a small office of 20 laptops. The 20 laptops are not always connected at the same time but sometime they are.

We have a Cisco 890 router with QoS. We have a single local file server, we use a lot of RDP, VPN, Skype, GoToMeeting, Music Streaming, File Sharing, Mail,  VPN with a branch office for file sharing and intranet.

The network itself is very very stable, no internet outage for 2 years, wired connected server show a 99.99% uptime on the internet.

Its another story for the wireless access points. We have a Cisco WAP200 (54mbps) and a WAP4410(300mbps) and they cant keep up. 1-2 reboot a week.

A quick survey indicates that there is about 40 wireless network in the same area, evenly split up between frequencies. (Maybe relevant if we had wireless stability problems ?)
The office is quite small, and the wireless covers everything without any signal loss.

I say its quite obvious that the wireless is overloaded because we use a bunch of applications that uses bandwidth. When 10-15 people connects to the access point, and then starting the VPN out, RPD out, file transfer with the local server, skype, GoToMeeting. It takes about 5 minutes and the wireless crash.

The manager says that the problem is more on the network side (Router), we need to ''tweak it ''. We don't have change the access points. I don't see more tweaks in a Cisco router, unless implement LAN QoS ?

I have read a lot about this and I think we should upgrade the wireless infrastructure with 2 enterprise class wireless access points and do load balancing.

Am I in the right track ?

    I think the Cisco stuff (enterprise)is overpriced and you need a service contract if you need to update buggy firmware or security holes.

    Ruckus has some nice stuff.,2390-8.html

    This problem still could be a lot of things. You have a lot of networks that could be interfering with yours and crashing it. You could have settings on the cisco wired side that could be crashing it.

    When crashed, does it recover in time. If so, check the wired side duplex settings to make sure it matches that exactly of the router and switches.

    I will test new APs during the next weeks and see if there is improvement. Prehaps its on the network side, prehaps its the APs that are overwhelmed.
