It
is possible to get Homechoice to work wirelessly with an ADSL modem/router (Belkin in my case) - but only for one wifi device.
To do this, turn off the Homechoice (HC) box and then I recommend a hard reset of the modem/router (press and hold the reset button for 30 secs or more) in case there are any odd settings you've made trying to get it work previously. Then, with a cable, connect a PC to the router (a LAN socket), access the setup page with a web browser (
http://192.168.2.1 on a Belkin), set any security that you need - such as router password, WEP key, MAC filtering etc. (as you won't be able to access the router setup page later on), change the SSID if you want to, and then switch off the router's DHCP (the key bit). Finally make sure that the wireless mode is actually turned on, again in the setup page.
Apply all these changes, then disconnect the router from the PC and switch off the router. If you know how, make sure your PC is set to receive IP dynamically (it should do unless you've changed it) and shut down the PC for good measure. Now, connect the HC box to the router, again with a cable to one of the LAN sockets.
Turn on the HC box first, and wait 1 minute. Then turn on the router, and wait 1 minute. Then switch on the wireless enabled PC, and it should detect the wireless network. If you've enabled a WEP key on the router, enter the key into the PC's wireless adapter settings and it should all now work. If not, final thing to check is the PC's internet settings, by opening an internet explorer, going to the tools menu, Internet Options, Connections tab, and make sure the option "never dial a connection" is selected. Then click on "LAN Settings" button and on the popup window make sure the only box ticked is "automatically detect settings".
This should work, it did for me. Main thing is turning off DHCP because if it is turned on and you connect the HC box to an ADSL router via a LAN socket, the HC box is sending an IP address to the router but the router is trying to send one back to the HC box, thinking it's a PC. So there's a conflict and in my case the HC box would simply turn itself off (and then on, and off, and on..). Turning off DHCP stops this conflict but then since there's only one IP address (starting with 81. from Homechoice) you can only use one wireless device. I now have 2 wireless devices so I had to buy a separate router without the ADSL part, I got a Netgear 108Mbps for £55 from PC world but there's also a Linksys WRT54G which you can get for £40 on Amazon
