@woozle ohh ok well I purchased it 2-3 years back so i think now its time to change XD anyways thanks dude for your help.

@woozle i have connected through a box of fibre connection which my local service provider have provided me and im using 5ghz connection but it says it support around 750mbps isnt that right?

I have installed new 100mbps fibre connection on my tp link router archer c20 ac750 router but the speed coming is only 80-90mbps is it getting bottleneck?
