The reason i asked is because i have a d-link dgs2205 gigabit switch connected to the dir-625 router. When connected to the router, i don't experience performance degradation when i have around 150-200 simultaneus connections on 1 pc. But if i moved the connection to the dgs-2205, i see slower download speeds and some sites would not load. I don't know if the switch also has its own limited simultaneous connection or maybe i just have a faulty switch.
