Problems with setting static IP address
I'm trying to create a static IP address for my iMac running OSX 10.6 to connect to my free router from my ISP (Thomson-Alcatel TG585v so that I can then portforward to try to access Bonjour via wifi (so iTunes can see my Synology NAS). I followed all the instructions on this website (suggested by my ISP) http://portforward.com/networking/static-Mac10.4.htm which are very straightforward but when I then try to log into the internet I get a message saying I'm not connected. Running network diagnostics doesn't help and as soon as I revert back to DHCP my internet connection reappears. I spoke to the technical support of my ISP but they confirmed I was not dropping my broadband connection when trying to use the static IP. I tried around 10 static IP addresses but none of them worked.
Has anybody else had this problem? Is it because I am using an Airport Express (802.11g) to create the wireless network rather than the router itself?
If I can't get this fixed then I will have to resort to a homeplug to effectively connect my iMac to the router so iTunes then 'talks' to the NAS. Can anyone recommend some reasonably priced homeplugs that work well (sub £100).
