Just recalled a memory. When I used to do cable modem support, I saw this problem, once or twice. Your current router is receiving a valid IP, because its been picked up by a DHCP server and it keeps extending the lease. When you change your router, it goes to a DHCP server and asks for a new IP, however if the wrong class of service is assigned to the cable modem (the wrong DOCSIS file specifically), then its possible that when the DHCP request is sent, it goes to a DHCP server which is full, or which is designed to block internet access. Simplified process: Cable modem power on Cable modem loads DOCSIS file, which contains settings, including effective routing to DHCP server Router power on Router's DHCP request is sent The DOCSIS file is chosen like this: Account system has flags for services eg 2mb, 10mb, 20mb, sky sports, etc Sending a "hit" from the account system pushes data to provisioning system Provisioning system (used to be called IIP) generates a DOCSIS profile based on these flags Soooo .... ring support, tell them you're having problems changing your router, and you'd like them to "send a hit" and if they don't know what you're talking about ask them to log a fault. Sending a hit is easy and was the first thing I was shown how to do back in the day, however I can't for the life of me remember the process now.
Digital settop box is the gateway, so the connection is as follows.... ...stb > router with built in switch > computer
Right so that makes a bit more sense. The stb has a router in it which gives you a private address on the ethernet cable. You're then plugging that in to a router which gives you a private on your WAN & a private on your LAN (effectively double nat'ing your traffic). Personally I'd ask VM to send you a proper modem as it'd be soooooo much easier to setup. If you want to change your router with your current setup, turn off your stb for about 10 mins at the mains, swap routers & turn it back off. This should release the learnt MAC address on the stb.
Maybe I can clear things up a bit... First things first, I am a QA tester at a major service router manufacturer, and my "feature" is NAT. The free public IPv4 adresses are quickly running out, and that is why lots of providers are making the move to CNAT (Carrier Grade NAT). There are multiple implementations of this, but what they all do in essence is provide private ranges 10.0.0.0/8, 172.16.0.0/16 or 192.168.X.0/24 to their customers, and aggregate them (with NAT) to a smaller range of public IPs. So, it is possible that you get a private IP from your ISP and it will become more common until all ISP start using IPv6 (which they should have started 4 years ago!).
CNAT is only done over here by mobile networks but not VM. It's the fact that the stb is a router as well that's the reason he's getting a private address on his other router
I've tried it all again to see if I can get it to work. Left the stb and router off for a while. Spoofed a Mac addy like suggested, but I still get the '10' in the WAN and no connection to the net.
Back on topic, how the hell do I change my router? I want one with built in wireless to replace the one I have, but I can't get the correct IP to turn up in it, so I can't get connected to the internet!
oh your running the linksys as a switch.. from the looks of the firmware it's pretty old- does it have a uplink port? the uplink just let's you run a regular cable to the router instead of a crossover cable.. but it's shared with port 1 (so if you use the uplink- you can't use port 1) so plug in your cable in the uplink.. it's using your stb as the gateway that's why your on 10 and assigned 119.. the stb ip address is set at 10.40.247.1 disable the dhcp server on the linksys and then on the computers connected- configure each of them static to open dns or ones used by your isp easier just to buy a switch, plug it into the stb and there you go
