Two Networks on Broadband
 

Hi,

Being a broadband novice, I though I would post this to check whether or not this is the norm.

I have had a 300K service from ntl for a few days now. Everything was going well until I got a "new network" message on booting up yesterday. I now have two internet networks that my PC is connected to and, in the light of security worries, wondered if there was anything amiss.

ntl customer support told me that perhaps the PC was seeing itself as an internet connection, but I am not wholly convinced.

I am running an ancient Win 98 SE setup, no bluetooth adapter or the like. Just the cable modem.

Can anyone enlighten me as to the reason for the two networks?

Much obliged.

Dave

Hi DaveW1970 :welcome: to Cable Forum

- do you use Zone Alarm, by any chance??

Re: Two Networks on Broadband
 

Thanks for the welcome.

Yep, I have got Zone Alarm installed. Is that the root of all ntl evil?

:LOL: hmm, some may say that, personally i have had no problems with it, no - I just wondered whether the 'new network detected' message had come from Zone Alarm, as I seem to remember something similar last time I re-installed it. :)

Re: Two Networks on Broadband
 

Ah, I see. I just thought it a bit odd that 2 networks were shown as I could see no real reason for it (as is the case for quite a lot that goes on at ntl methinks).

Cheers anyway.

ZoneAlarm produces this message every time your IP address changes from one sub-net range to another. This is liable to happen at any reboot on a cable system that allocates addresses via DHCP.

Thanks for the help. Would this explain me being connected to two networks (as indicated by two internet ip addresses as shown in ZoneAlarm)?

Thanks Robin - I could remember getting the message before, but that has clarified why it happens, much obliged :tu:

Re: Two Networks on Broadband
 

You aren't connected to two networks. ZoneAlarm is confused.

Quite true, had a root around (using winipcfg) last night and found that it had given an IP address to a generic "Microsoft TV adapter" which it had installed at the same time as the cable modem.

Problem solved :)

Thanks for all the tips :tu:
