Limited access to Internet using router

[Mattrixx]

Hi, DSL user here posting for my daughter who has Comcast Digital cable TV
and Internet.

I recently connected a Netgear router for her, installing the router after
the modem, and before the desktop (and wireless laptop).

Upon initial connection/setup, everything seemed to be in order as both
computers were able to connect online, go to various sites and also I
network shared files between the two computers with No difficulty.

After I left her place feeling accomplished, it seems *NOW* she is only able
to connect to certain limited sites, but *NOT* to ALL!!
She cannot for example, access her hotmail account along with very many
other sites! She can however access E-Bay and Newegg, Google etc. Some of
the sites load in a very limited what she calls "primitive" state with NO
pictures etc.

By phone, I had her disconnect from the router and plug directly into the
desktop from the cable modem, and all is fine! She then can access any site
without a problem.

So somewhere in the Netgear router lies the problem??
As I have said, I am familiar with SBC/Ameritech DSL.
This is all Very strange for me to hear since with DSL, it is ALL or
NOTHING!!!

Can someone here point out to me what might be a probable cause or setting
with the Netgear router, that might be affecting her ability to access *all*
Internet sites while using the Netgear router?

For example: Is Comcast a Static or Dynamic ISP ?
I have left default *Dynamic* in Netgear Router`s Basic setup Interface.

Thanks for any insight into this matter from any experienced Comcast
Internet/Router users

Matt

If you can get to the Internet at all, you have something configured right.
Some cable modems "bridge", or really, act as a media converter. The router
or computer connected actually gets the IP address. Some other cable
providers use modems that perform "network address translation", like your
router - so you can connect multiple computers on the "inside" to the
Internet using only the single IP address assigned on the "outside". Either
way, you should at least be able to hit the Internet and get full web pages.
If you're not, it's probably a DNS issue. Try putting your ISPs DNS server
settings (you can call them and ask for that information if you don't know
what it is) into your daughter's computer's TCP/IP settings manually. To
test whether or not DNS is the issue, find a web site that you know she
can't get to, then open a command prompt and type "nslookup
<www.website.com>", i.e. nslookup www.google.com, and see if you are
returned an IP address or not. You should also get the name and IP address
of the DNS server that performed the lookup.
