My new router, the Covr-3902-Us, does not seem to handle my wireless devices as well as the old DIR-880L. It disconnects some, assigns new IP addresses for some, even though the device has a fixed address. I have 14 constantly connected wireless devices and several others such as laptops, tablets and cell phones but never more than 20. The DIR-880L seldom disconnected any of them and if it did they were quickly reconnected. The reason for replacing the DIR-880L was that the firmware could  not be upgraded for some reason even though newer versions of firmware are available. I don't know how to fix the update problem or how to revert to the original version even though I have done a reset more than once. Any suggestions?

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
• Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
• What wireless devices do you have connected?
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner to find out. How many?
• For routers with Smart Connect Technology , try disabling this feature and test. Under Wireless.
