Configuring a Speedport W503V - Germany

Hello:
As an English speaker I find the W503V difficult to understand. Does anyone know if its possible, and if so step by step how to do the following:
1. change the WIFI password?
2. change the router name?
3. restrict access to the router by MAC address?

Looking at the sub-menus in the router I can't figure it out, since its in German. Is everyone happy with this router?

Thanks.

It's a decent box.

You change SSID and WLAN security over the menu item "Konfiguration / Sicherheit / SSID & Verschlüsselung“ and MAC filtering over "Konfiguration / Sicherheit / WLAN-Client Zulassung“

I too am stumped by the speedport W 503V . It seems that I have full reception on my computer but the wifi signal drops intermittently. I am in range of several different neighbor wifi networks. I am guessing that they too are signed up with t-mobile, are using a speedport, and their speedport is occupying the same wifi channels.

I once heard that wifi signals run from a channel 1 to 11. And if there is a full channel it can affect your signal (interference). Does anybody know how to modify the wifi channel my speedport is broadcasting?

I am able to access the configuration page.

Thanks.

Konfiguration / Netzwerk / WLAN (Wireless LAN) -> Kanal
=> take one about 5 units above or below the current one. If auto was set, try one of the higher numbers.

A different alternative would be, if your computer's OS allowed it, to select (only) 802.11a+802.11n, instead of the typical 802.11b+802.11g+802.11n range where handsets and microwaves operate.
