Unable to connect to http://192.168.0.50

Hello,
Yes, the DWL-G700AP can be setup as an AP or a repeater as long as your current wifi router is also 802.11g/b.
You can find instructions here: http://www.docstoc.com/docs/2583739/How-do-I-configure-repeater-mode-on-DWL-G700AP

You should be able to connect to a wireless printer. Before trying to connect it just read the instructions supplied with the printer and do a dummy run without turning anything on so you have an idea what you should be doing.

Make sure you're installing the right drivers for your version of windows, if not on the disc, download them from the manufacturers website.

Under Windows 7, press the "Start" button.
Type 'cmd' into the search-box, and press ENTER.
Type 'ipconfig /all', and press ENTER.
Look for the IP-address for the "gateway" (or "DHCP-server").
Type that IP-address into your web-browser.

you can connect to your box via FTP via a crossover cable. If you can’t, you might want to read up on that before attempting this.
Now, what we’ll need is…
Ethernet cable (crossover or patch)
Router
Modem
We’ll also assume that you have a router (wireless or not) and that your modem is connected to the ‘Internet’ or ‘WAN’ port.
If you have a free port on your wireless router, you can connect your dreambox to this. Use the ethernet cable (crossover or patch, most modern routers will accept either) connect one end to your dreambox and one end to a free port on your router. You don’t need to change any settings on your router or PC.
Over to the dreambox. Navigate to the networking page on your dreambox.
Setup -> Expert Setup -> Communication Setup

This problem occurs because of DHCP issue in router.
Your computer not get proper ip for connect network.
For that first reset router to defaults.
Press RESET button for 10 seconds it is in back side of router.
Then connect router to computer with ethernet cable.
Then you can access it with following link.
http://192.168.1.1
or
http://192.168.0.1
type user as "admin" and password as "admin" or blank or "password"
then you can see configuration of your router.
Set WAN settings as your internet service provider settings.
Enable DHCP in advanced.
click on wireless or wi fi menu and enable wi fi .
Enable WEP or WAP security if you want to secure then add key it is your password to connect internet.
Then save and restart router then check.
Let me know if you need more assistance.

On this tip you can find an easy check list let me know if you need more help

Your router latest Firmware I can see on D-link website is 1.02
If you are referring to German web site page showing a dwl-g700ap_fw_revB_v213b06.zip file be sure to follow the instruction to UNZIP the web_dwlg700ap_v200_r11_0408.bin file:
DWL-G700ap Firmware Update

- Browser starten
- Konfiguration des DWL-700ap aufrufen (Standard IP 192.168.0.50)
- oben auf Tools
- links auf Firmware
- auf den Knopf Durchsuchen klicken
- die Firmware Datei (web_dwlg700ap_v200_r11_0408.bin) auswählen
- auf Apply klicken

Wenn die Firmware installiert und der DWL-700ap dann neu gestartet ist klicken Sie oben auf Tools/System/Restore to Factory Default.

Danach ist die Firmware übernommen.
If you did not unzip the bin file router cannot run it as firmware update
More over be sure to run the update via LAN cable connection (no WLAN)

Is this access piont connected to a router? Can you get online through the router? If you can go online through the router also check the status of your wireless connection. Make sure its connected and it's getting a valid ip address.

that is right the access point does not have a dhcp server. that will give an ip address to all of your computers or device connected to it wireless. If you have a modem with a dhcp server there will be no problem with the IP but if the modem does not you must have a router and now an access point.
