I have purchased this Archer AX 80 router on dec,2023 . it was working till when my plan was in 80mbps 

As i have upgraded my internet plan from 80 mbps to 150 mbps from my isp provider, i am not getting my plan speed from this router . when i was checking the setting of internet negotiation it was only showing 100mbps,

if i change the internet negotiation setting from AUTO to 1000mbps full duplex ,  router will disconnect from internet and no connection at all,
router led will change from blue to red , it was stuck with 100mbps full duplex

I have even changed LAN internet Input port from 2.5gbps wan/lan to 1gbps wan/lan port . and visa versa , still the problem occurs.

EVEN  the TP link technical team can't able to rectify the issue.
