EAP620HD access point with same SSID as router dropping constantly
Hi,
Our house is quite long and therefore the wifi coverage at the front is quite patchy. As a result i bought a EAP620HD access point and installed it in the front room to serve our cameras at the front of the house. The access point is connected to our router via ethernet cable and the router is a tp link archer AC1200. I have set the access point up with the same SSID and password as the main router.
I have noticed that after setting up this will work for about a day with no issues and then dropouts start happening, all the cameras send me a notification saying they have lost internet connection. I then try to connect to the wifi at the front of the house and can no longer connect to view the router login page to check what the issue is, so i hard reset the router and set it all up again and repeat until the drops start happening again.
I have tried multiple things i've seen online to rectify the issue, like setting the access point to a static ip and setting the gateway to be the ip of the main router, and reserving the ip for the access point's mac address in the router but nothing seems to work.
Please advise if you can.
Thanks
