Iam using a older d link df e 908 dx 8 port hub over years a massiv build heavey device works well since to 2 ago!

While my main DSL connection seems to be always active ok over WLAN

The hub lost connection and a yellow light , with the name COL Is blinking yellow 2 secounds and then the nabour digits 4 pcs blinking green , what does col mean?

I always have to reconnect the power cord , that my connected devices over LAN found connection again but this 2 times a day!

Any ideas?

COL probably means packet collision, two devices sending packets on the same wire channel at the exact same time = garbled packets.
