Network Upgrade
One of my recent and for me exciting "Technikhilfe" jobs was to upgrade the network of a bike-shop with residential rooms above.
I got this request shortly after finishing my CompTIA Network+ exam and was immediately excited for this opportunity to take the learned concepts into reality.
The clients network was suffering from sporadic connection loss and speed drops. After assessing the network, they had installed a new Fritz!Box 7590 along witch three D-Link DAP-1360 access points running four separate SSIDs on overlapping 2,4 GHz channels on WAP security. Cabeling was consistent on CAT7 and wired speedtests showed good results.
I concluded, that the old access points probably were causing some issues. As a result, I ordererd four TP-Link EAP653 AX3000 Omada APs and a TP-Link Omada TL-SG3428 24 port switch to replace the two 8 port unmanaged switches they had installed. I installed a Omada software controller to configure a shared ESSID and roaming between the APs and deactivated the wifi of the Fritz!Box to avoid overlapping channels. The four access points were spread across the bike-shop, the workshop and the home above to provide sufficient coverage across the complete building.
After all this was done, the wireless devices had no more issues connecting and wireless speedtests also showed consistent good results. Above you can assess the logical network diagram.
