u/Ice_on_floor

ISP Device : GX Earth -2022 (modem+router)
Router 1 : tp link archer c6 (now set as accesspoint)
Router 2 : dlink dir -819
Housing walls concrete 1 feet thickness

Isp Device is shit no range, could not enable bridge mode, ISP not allowing via UI from my side .
Decided to make my router 1 and 2 as accesspoint .
Issue 1: there is no AP mode in router 2 , only showing router mode and repeater mode.

Currently there are 6 wifi in home at different locations . Each router having both 2.4 and 5 .
Does Setting same SSID and password solve the prob? But my confusion is even if the range is higher in ISP router , its not stable. Or disabling the wifi in ISP router solve? Please help
