I have a wifi replacement AP R550 instead of R300 of the clinic with 4 floors. all the AP are connected to Smartzone 144 with version 6.1.1.0. After replacing the AP, the client are experiencing the wifi disconnected and request time out issues. the APs are mounted in the walkway, we can get good signal strength in the walkway, but can't get in the rooms. in the previous AP, it isn't happen like that. These APs are mounted relatively close to each other within 20 meters.
I'm looking to mitigate interference as much as possible. I have set 2.4 GHz and 5 GHz to default channel width. I am using 1,3,6,8,11 for 2.4. and 5 is default setting. The ground, 1st, 2nd floors, are experiencing wifi issues disconnected and frequently drop the connection, maybe interference but the upper floor wifi connection is good.
Please kindly suggest to mitigate the interference. Thanks for any help!
