Tp link c6 v3 slow after update
I recently bought tp link c6 v3 router. I was using very happily.The router firmware was none updated in stock form.I was getting 90+mbps speed undoubtedly. Pretty fast bandwidth provided by isp. Recently i updated the firmware version to the latest one 1.0.14 Build 20211118.Now after update,my router is no longer giving me that previous performance.Its now giving 27-30 mbps.WTF.I thought changing the negotiation setting auto to 1000 maybe fix the issue but it didn't work.What should i do now?I am assuming its maybe router setting or firmware problem.My bandwidth is okay.I was getting 90+mbps exact second before the update.
