Random Performance Degradation w/ Office WiFi on AirPort Express APs
Greetings all, I've been a longtime lurker and finally bit the membership bullet in order to ask this question.
I work in an office of ~40 people where almost every user has a laptop connected to one of two wireless APs. We have an Apple AirPort Express 2nd Generation AP in each wing of the divided office, both feeding into our Cisco RV220 router/vpn station and broadcasting the same SSID name. We have a business-class broadband package with a static IP. The APs are broadcasting with the 802.11n standard on the 2.4GHz spectrum. Both are running firmware version 7.6.2 (not the latest).
Every few weeks, users in one half of the office (connected to one of dispersed APs) suddenly experience dramatic connection problems. They maintain a connection and IP address, but the link speeds drop to between 11 and 18 Mbps. Our laptops normally connect at 48 or 54 Mbps, so the drastic change impacts remote RDP sessions, Join.Me conferences and general productivity. I've gotten in the habit of rebooting each AP when any connectivity issues arise.
Several weeks ago I changed the broadcast channel on one AP to channel 1; previously, both had been broadcasting on channel 6. The fact that we have several neighbor wireless networks on channels 6 and 11 prompted the change in hopes of reducing crosstalk. Both APs are transmitting at 100% power, so I've considered dropping the power to 50% for the AP located in the largest open space. The other one serves users through multiple walls.
Aside from our obvious need to upgrade our overburdened access points, do you have any other troubleshooting steps for me to try? I'd be happy to provide additional information; I'm not sure if I've supplied too much or not enough. Thanks for any assistance!
