Connection timed out accessing Admin Panel

Logged on to GL WiFi network, accessed 192.168.8.1 one time, it soon “timed out” and now I cannot get back to the Admin Panel. The network through GL-A1300 is working fine, Internet throughput is as it should be. Just cannot access the Admin Panel, even after a rebook of PC.

Update: I got back after reboot of PC and clearing caches on browsers. Now, I can’t keep the router up. It runs for a few minutes and then drops connection. I’ve factory reset and it keeps timing out after just a few minutes. Any thoughts?
