>to isolate if issue is with isp or router, bypass the router and connect pc to modem and check the stability
>if issue persists then contact isp, if not connect back the router to desktop
>open the router interface and check for firmware upgrade
>upgrade it, if there is one and then check for intermittent connection in wired and wireless
>then once again u can reset router and is called power on off reset
1. U need to reset with a pin/paperclip and then remove the power from router while holding reset
2. again plug the power back, still hold the reset
>Repeat two steps for abt a minute and then wait for LEDs to be green
>reconfigure the router, even the issue persists then router is faulty
>call the tech support and tell him, router is faulty and tell them that i've done all possible steps to fix
