I have a DI-604.  By default, it will provide to client computers a DNS IP
equal to its own (LAN-side) IP.  That works fine on my network.

I would not expect that cable companies change their DNS servers' IP
addresses that often.

Subject: [PCBUILD] DNS and router/pc settings problem

Since this community has been so helpful with my previous virus problem, I
thought I'd appeal to you folks again for a new development on a different
system.

It's a D-Link 604 router with the latest flashed firmware.  When either pc
on the network is connected to the cable modem, no problems.  When either or
both pcs are connected to the router, most web pages require a refresh to
display the desired site.

I thought it might have been an incorrect MTU parameter and I used the
support section of the dslreports.com web site to do some tests and made
some changes.  Got it to work for about three minutes and then it "failed"
again.

Tech Support at D-Link was stumped too, but I had called them before I
discovered one other aspect...

I got a hint that it was a problem with DNS, on the win98 machine when it
reported "unknown host" on one of the ping tests.

I then took the DNS settings from the modem/router and manually entered them
into each of the two machines and the problem went away completely.

First question:  why did my "solution" solve a problem that does not seem to
exist on other networks I've configured, including my own?

Second question:  I have the feeling that setting a static DNS is not a good
idea.  How often does DNS change for the "typical" cable company service?
If they change DNS settings, the router will update, but the pcs on the net
will be at my original numbers.

Last question:  How many words in quotes are too many?  :-)

thanks in advance for your advisories.
