OK ive had this problem, if IP binding (or address reservation) doesnt work, set a static IP on the box, so find your subnet that your router uses (192.168.0.X or 192.168.1.X)
assign ip address
ip address = 192.168.X.250
subnet = 255.255.255.0
gateway = 192.168.X.? (router address)
dns = 192.168.x.? (router address)
secondary dns (if it lets you) 8.8.8.8 (googles free one)
X = your subnet address variant it could 0 or 1
? = your routers ip address which is normally the first vailible on the network, so 1 normally, but BT homhubs have a tendency to use last (254)
sometimes the spider boxs will just not get an IP assigned from DHCP. The reason i chose .250 for box ip is normally most routers choose anything above 100 to assign DHCP so theres a very good chance 250 wont be used by anything else on your network.
CCcam crashing, if your server is running cccam 2.1.2 / 2.1.3 / or 2.1.4 then you it will, you need a server that runs 2.1.1 for the spiderboxs to run nicely. This is true in 99% of the cases, if anyone tells you that all spiderboxs run fine on 2.1.3 / 4 they are talking shite.
there is of course a chance that your server is having problem, but this is a known but not admitted problem with the spiderboxs.
other than that they are good boxs and excellant piccy quality.
