Asked this question previously, but it wasn't as detailed as this.
I had my network speed improved by my ISP, I tested the network speed from the Fiber media converter, the speed was awesome, tested it in some offices (both wireless and LAN ports) the network was still fine, but in some parts of the same building, the network is dead slow, as first I suspected coverage, that's for the wireless, but I tested the LAN ports, they were also slow. Can someone please help out on what might be the cause of this.
So this is the flow below
ISP => Media Converter => Juniper Router (SRX 550) => Cisco Switch => AP Access Points
NOTE: VLAN hasn't been setup on any of the switches.
I'll also appreciate an advice on how I can improve on my flow to better the security architecture of my network.
Thanks in anticipation.
