Hi
Cheers for the replies.
There is no problem gaining internet access from any of the computers connected wirelessly to the router.
Connecting the DSM via wireless works fine, I use a wired connection because the two boxes are next to each other.
The router IP address is 192.168.1.254
The router has a firewall and I am using McAfee security software, I thought the problem might be down to the firewall, the Windows one is turned off as McAfee is handling it, so I tried turning the router and McAfee firewalls completely off, still no luck. So it cannot be a firewall or port forwarding issue.
As mentioned before, streaming music/video/pictures to the DSM it works great, assigning IP's either static or via DHCP is no problem, when given the opportunity the router assigns it 192.168.1.3
Hope any of this helps.
Best Regards
Nigel
