I don't see anything wrong with this. I assume you have allowed for autodetection and have not configured anything in addition for ipv4, did you enabled ipv6?

No ipv6 is unticked should it be reticked ? What will ipv 6 help me with ?

aem · 04 Nov 2009

Sorry i meant disabled. Leave as disabled. I had another read of the first post and you said you are gettn DNS server not responding.

DNS server issue, if you have not manually configured one in your ipv4, than it has to be from your ISP. Your modem does not go out to your ISP to gather details, it's your ISP that propogates the details to your modem.

Is your setting set to autodetect and in your WINS, is it Enabled "LMHOSTS lookup"
with Netbios Setting as "Default"?

Not true. Modem requests configuration from isp's tftp server.

Is this a hardware issue if so is their a good nic card out their that will support win7 out of the box or is this isp related? any and all help figuring this last issue out i hope will be very appreciated :)

Archangel83,

After the Internet Error, did you try to ping your DNS servers?
Open cmd, Start->type cmd in searchbox, enter.
In the cmd window try this:
ping 208.67.222.222
ping 208.67.220.220

also enter next command:
nslookup <enter>
in nslookup, enter next address:
www.google.com

please copy and paste results to this thread.

Have a nice day!

Hmm I'd like a third opinnion on that if that's ok. Modem by loose term is a device that converts analog signals to digital...when you say requests configuration, i don't agree. The ISP has a open/close "link" to your modem (through their own modem device). The ISP's DHCP is what provides the IP but not in the x.x.x.x format, modems do not go to ISP and specifically asks for IP, it sends a signal of service (not configuration data, just signals) and the ISP reply with signals which the modem "demodulates" to data needed.

Actual configuration of data happens on the machine within the OSI model. From your modem to the ISP's "modem" device that is the internet, there are only 0s and 1s.

I used to witness isp hacks when I was a bit wilder back in the days. I know how things work and I do so well. I would see how people's mac addresses could be used when they posted them online.

Hacks/spoofs possible are alterting sync speeds and also outright using others' accounts. Not advisable to post mac addresses online.

It's weird, your IP is 76.190.235.248, and when you do the nslookup, your default server's IP is 208.67.222.222. So neo.rr.com (your ISP ??) is using opendns.com's service as DNS.

Anyway lets try this.

In your Properties > DNS tab

Append DNS ...

Can you check your WINS tab, does it look like this?

And auto detect settings.
