i recently bought a ASUS RT-AX59U as an upgrade to my old VM hub 3. speedtests give good results but most of the time when loading something or even just accepting cookies etc it takes 5-10 seconds to begin loading. thew hub 3 was very slow but there was not a lot of lag. can anyone point me in the right direction of what to check. i used the router recomended setup and put hub 3 into modem only
