FRITZ! Box 7590 DSL
I want to hang the FB (via WAN connection) behind an existing network to increase my WLAN range. The attached router is not an FB. In itself, this also works wonderfully - but when I do a speed test in the FB WLAN, only about 1/20th of the speed of the "mother router" comes through. I have already tried several cables - no difference. Is this normal? What could be the reason for this?
