Virgin Media Change? - Ambit 250/Haxorware 1.1

[veryfriendly]

Hi

I have an Ambit 250 which was working fine after I upgraded it from Infinite to Haxorware (1.1 v30) last week. I also did the same to a friends. Both as of this morning fail to sync (Area is Reading).
I've looked on my unmodified modem and changed my downstream freq to that but it didn't make a difference.

Is anyone else having this issue at all? I've tried going with a legitimate config file but that doesn't work either.

Thanks in advance for any help given.

no one else from Reading has posted that they are having problems, I think the answer lies in the fact that you did both modems with exactly the same settings.
Are you positive that the macs are good ?.
this is still better than infinite, you are having teething troubles definately.
you need someone from the Reading area to give you the correct settings.

I'm using the cmreg-ntlhm250-rts22.cm and was all last week. I specified force as I didn't know what the tftp should have been anyway at the time. I don't get a lot of time to play around with this stuff and troubleshoot at the moment as I have a young baby that keep my a bit busy :-/

The MAC's are cloned off our unmodified modems and they work ok. I'm scratching my head as I can't think what to try next.

Should I be using a tftp server IP or forcing. Is there any one which is more stable?

[TechWreck]

yes force tftp ip it will find it its self,thought that was enabled by default though ?
also leave the config blank to see if you can get on the net

I've just turned off the force tftp and it's used the cmreg-ntlhm250-rts98.cm config file from the virgin tftp server. It worked for a while then it dropped.

Looking at the log it syncs briefly then drops the config file.

This problem looks like some kind of setting that's being pulled during the handshaking even before the config file.

have you spoofed you nic address on your pc/laptop ?

[veryfriendly]

I've done nothing with the PC. I was using a router but I'm just using ethernet direct to a laptop to troubleshoot.

[TechWreck]

try spoofing the nic address on your lan/ethernet adapter use TMAC or smac to do this,just change the last two digits of the mac to something else.

Make sure your not using a mac from the same UBR as urs as it will connect then a min or 2 later it will kick it off the network.

Don't clone the Mac off your own subbed modem you nutter!

I'm guessing you are running the subbed modem and hacked modem at the same time....2 modems on same UBR with identical MAC's = dropping connection.

I wouldn't worry about changing the MAC on your LAN adapter for now, you need a new HFC (modem) MAC.

You can get one using bruteforce in DHCPsniffer from your subbed modem. For now don't force the config file, check the modem gets the correct TFTP IP (you'll get from sniffing with your subbed modem), and disable BPI.

cheers, fitz.
