Original problem:

I've used ICS sharing for years with a 3G dongle providing the internet connection being shared via WiFi Ad-Hoc network through ICS.

What changed?: I bought a BlackBerry - will not connecto to Ad-Hoc WiFi networks. ?I bought an Android mobile phone -? will not connecto to Ad-Hoc WiFi networks.


Solution attempt: I bought a stand-alone WiFi router.


Results so far: ?The Android immediately saw the new router's WiFi network and connected to it. ?Using the Android browser I can browse to the router's configuration page at ?That's about the end of the good news. From the laptop I can ping the the router from a CMD prompt but I can't browse to the configuration page. There appears to be a conflict between the 3G modem and the LAN connection - something to do with ICS perhaps?

Does anyone have any experience of trying to do this?

Is it actually possible to do what I'm trying to do? ?What am I trying to do? I'm trying to establish a NON Ad-Hoc WiFi connection for the house using my 3G USB modem as the internet connection. ?I need an 'Access Point' connection in order to browse using the Android and BlackBerry which won't connect to Ad-Hoc networks. I know the router WiFi is working because I can connect to is using both the Android and blackBerry phones. All I want to do is to complete the final step of coupling the internet connection through to the router.?

The router expects an ADSL connection which of course I don't have but since it has 4 LAN ports I assumed that it would be possible to connect it to an internet enabled LAN connection, i.e. that of a PC. Was that never going to be a possibility?

Thanks in advance for any help that you give me.

ICS uses the IP range and distribute addresses in that range. You will need to change the router to use another range ( for example).

You will find out that it will work ok for web browsing and emails, but anything else will start having problems with double NAT.

If its an adsl router then you can not use it as a router that simple, as routing is between WAN and LAN interface, really not a good choice in my mind to buy a router that can't be used as such. You could have just bought an access point. You have to put router's LAN interface on the same subnet as ICS subnet. Turn DHCP off on router and have ICS perform that function.

I changed the router ip address to and it works now on everything except this Win 7 Vaio which is connected to the router via a Lan cable.


Thanks for the help.

Everything's now working - the problem with Win 7 was down to DHCP not being enabled in the router. Somehow I managed to trigger a self-diagnostic which found the DHCP problem and re-configured it by itself - remotely. Quite impressive. So everything works and the network had more range to boot.


Thanks for your help everyone.
