To extend my connection ports, I have bought a second TP-Link switch TL-SG108E. First, I connected them in parallel with my router, but ti gave unexpected network behaviour. Now I am trying to connect them serial.
What is the best configuration ? Do I have to change some switch settings to optimize ? Both switches have different versions of firmware (v3 and v6) ? Recent version is v6.6.
Is it easy to do an switch firmware upgrade ? Do you have documentation ?
