The wireless router of KD made problems for me. You could connect only in the immediate vicinity. So I have the WLAN and the DHCP function in the KD-off device and switched the unit on bridge mode. Now it was a pure DSL modem, where you could connect another wireless router. The overwhelmingly positive reviews of WDR3600 in conjunction with the price brought me to this unit. The device, the wireless router lasted barely ten minutes. The supplied installation program (f. Windows) executes a single through the steps, you ultimately have to make only two specifications, namely the SSID and the WPA2 key. Actually, you can even these two values left at the default settings, which is not advisable. The software is not installed on the PC by the way, but is simply running from the CD. The signal (strength and link quality) is everywhere in the house more than 90%. Even in the neighbor's house (detached), the signal still has a thickness of about 80%. The compounds are absolutely stable. I want to clarify something, although it should be already clear. The WDR3600 is a pure wireless router without DSL modem, which is quite common. Those who receive cable television (KD or UM), must anyway using the modem of the provider, but also who is a customer of a classic Internet provider, a modem must Upstream. A very strong buy recommendation from my side!
