 |
|
Since yesterday afternoon I've been having connection issues. I have a two
computer network at home and my connection is via a Sprint broadband card
plugged into a Kyocera router, which feeds both computers.
Sometimes it won't connect at all or I can only receive mail via Outlook, no
other web sites work. Other times I can connect but then only to certain
sites, such as Yahoo mail, or Craig's list. When it does work, it loads
without graphics and everything is just text on the screen. The annoying
pop-ups are gone and so are all the ads. I tried uninstalling AVG but that
didn't change anything. The error message I keep getting for sites is that
it can't find the server. I'm using both IE and Mozilla and get the same
errors. The other computer is running IE and having the same troubles.
Sometimes the only thing that works is mail, using Outlook, no other web
connections, including newsnet. I get the error that it can't find the
server for newsnet also. At the moment, everything is working, but this
happened earlier today and then everything quit again.
When it does connect the speed is fine.
I don't own a laptop so I can't know if it would be a problem with the
Sprint card. I do have Network Magic and I've reset the connection several
times and it says there is nothing wrong with the network or the internet
connection. It resets the IP address and says the connection is fine, but
it didn't work.
At the moment, everything is working and I did a speed test on Speakeasy and
it's showing 750kbps which is average for my connection.
Is it possible there is Internet server troubles for the last 20 hours or do
I have some kind of trouble?
Any thoughts appreciated,
Joe |

Open a DOS box (command prompt window). Try
nslookup www.altavista.com
The returned result shows the results of a DNS lookup, which converts
a symbolic address, into a numeric one (72.30.186.25). And the server
that was consulted, to get the answer.
If there is a long delay, before the answer returns, it means one of
the DNS servers in your list is not working. And as far as I know,
Windows evaluates them in the same order all the time. So the duff one
will be checked first every time. (Other OSes may be clever enough to
consult the known working one first.)
My internet connection uses DHCP for both my router and DHCP from
my computer to my router. In both cases, DHCP automatically asks
for the DNS server addresses from the DHCP host. Two are provided as a
rule, which is intended to give some redundancy against failures.
And in some cases, one or both of the suggested DNS servers might
not actually be working. (Although lately I cannot say I've had
any problems, so they've gotten better at keeping them running.)
You can also assigned DNS addresses statically. My router has
room for a couple entries in its WAN setup page. And in Windows,
I suppose you could disable DHCP, and do some assignments yourself.
The trick is, to know some DNS addresses at your ISP to use.
(Mine used to serve a lot of users through some main DNS servers,
but has now distributed things a lot more. You could do a
reverse lookup on your current DNS addresses, to figure out
whether there is a naming convention for them at your ISP, and
then try some other similarly named nodes.)
Also note, that there was a recent change to DNS, in that during
the last Windows Update, a change was pushed out to fix a DNS
exploit. That would have happened on Patch Tuesday, which is the
second Tuesday of every month.

Tried nslookup and got the following:
SERVER: unknown
Address: 192.168.0.1
Unknown can't find nslookup: non-existent domain. Since I was able to this
right now, everything is working ok, but it quit for the 3 previous hours.

Tried nslookup and got the following:
SERVER: unknown

This is what mine returns. I used this command, to dump the DOS output into
a text file. The ">" redirects STDOUT to a file.
nslookup www.altavista.com >out.txt
And this is the output.
Server: UnKnown
Address: 192.168.1.1
Name: avatw.search.yahoo2.akadns.net
Address: 72.30.186.25
Aliases: www.altavista.com
The reason the server is unknown, is because there is no reverse mapping
for a private address (192.168.1.1). In other words, the computer asks
the router. The router in turn, consults one of the two DNS servers
it was passed, via DHCP, from the ISP. There is no symbolic equivalent
to 192.168.1.1, which is why it has to remain "UnKnown".
But I can see the actual servers used, in my router setup page.
The fact that I got a translation, means it worked, and one of
my two DNS servers at the ISP, was working.
For people who have a static setup for their Windows computer, the
server name could have been translated and named, because then the
nslookup program would be dealing with a public DNS server directly.
If you're not getting the "72.30.186.25" part of the answer, then
DNS is broken. You could talk to the staff at your ISP, for example,
to seek a resolution. I've used workarounds in the past, to avoid
phoning them  Such as manually setting up DNS, when there is a
problem. Now that there are so many more DNS servers at my ISP, this
no longer seems to be an issue here.

Hi Paul,
Thanks for the replies but you're now talking over my head.
What does that mean the "DNS is broken"?
I also don't really know who my Internet Service Provider is?
I connect using a Sprint broadband card. Would Sprint be my ISP?
Sorry for the dumb questions!

DNS, Dynamic Name Server. DNS assigns the IP address of stuff conected to
it.
You can be sure the Internet is not broken.
Your trouble is that the router you are using is having trouble, or your ISP
is dropping the ball. Yes, Sprint would be your ISP (Internet Service
Provider) IP is Internet Protocol, everything has an IP address. Your
broadband card does not tolerate being the Internet connection point for a
network, it only works for a single machine. I suppose in theory, it could
be hosted by a router, then a network could be built around the router that
uses the broadband card. I have to worry that the quality of service (the
ability to send and receive packets of data) would be diminished in an
architecture like this. I recently tried to network behind a machine with a
broadband card used for Internet access, and it did not work. The host
machine (the one with the broadband card in it) reported the second machine
as a conflict with the IP address -- basically, it said two machines with
the same address is not acceptable. |

Somewhere, in the documentation you got from Sprint, there should
have been a phone number to call, to get support for your Internet
service. That is who you want to call now. If the conclusion is,
that DNS (domain name service, translating symbolic addresses, to
numeric addresses) is broken, then you should talk to the support
people.
Another way to evaluate this. If you go to your web browser, and
type in
http://www.altavista.com
and that doesn't work ("server not found" or whatever).
And then you try instead,
http://72.30.186.25
the second format avoids the DNS translation you should have working
for you. Nobody wants to type in or remember numbers, which is why
we have symbolic addresses instead. The DNS server performs
the translation from the first form, to the second form. The
number form is needed, because numbers are stuffed into the
headers of each packet, indicating where the packet should
go.
DNS servers are an integral part of the service. The "fat pipe"
to Sprint can be working, but it there is no working DNS server,
it'll be damned hard to get anything done.
If your router has a WAN page in the setup for the router,
you might see the addresses of the DNS servers listed.
Keeping track of the DNS servers that are working or not
working, might help when you're talking to Sprint. In
case they offer the usual "we don't see a problem here sir"
kind of answer. I know I've had to do extra research work,
to get any kind of admission from the support at my ISP,
which is why I don't waste a lot of time on them.

It's not a dial-up modem, but works in much the same way but faster.
I would suggest he disable all of the machines on his network and try the
card with only one machine. If this improves things, then his hardware is
all working properly, but the modem can't support all of the connections at
the same time. Basically, he has a QoS issue |

Hi Jeff,
I thought you had sorted that issue ?
Did you assign a static IP for the second machine and put the mapping
into the hosts file.

DNS, Dynamic Name Server. DNS assigns the IP address of stuff conected to
it.
You can be sure the Internet is not broken.
Your trouble is that the router you are using is having trouble, or your
ISP is dropping the ball. Yes, Sprint would be your ISP (Internet Service
Provider) IP is Internet Protocol, everything has an IP address. Your
broadband card does not tolerate being the Internet connection point for a
network, it only works for a single machine. I suppose in theory, it could
be hosted by a router, then a network could be built around the router
that uses the broadband card. I have to worry that the quality of service
(the ability to send and receive packets of data) would be diminished in
an architecture like this. I recently tried to network behind a machine
with a broadband card used for Internet access, and it did not work. The
host machine (the one with the broadband card in it) reported the second
machine as a conflict with the IP address -- basically, it said two
machines with the same address is not acceptable.

Hello Jeff,
Today everything is back to normal and working, so I don't know what the
problem is/was. As far as the broadband card and network, I have been
running that configuration since December without any problems. Two
computers, both wired to the Kyocera router which has the BB Card.
Thanks for the reply,
Joe

Well, I guess it must have been their problem yesterday. All is working
normal today on both machines.
Thanks for your time in replying!!

Tried nslookup and got the following:
SERVER: unknown

previous hours.

This is what mine returns. I used this command, to dump the DOS output
into
a text file. The ">" redirects STDOUT to a file.
nslookup www.altavista.com >out.txt
And this is the output.
Server: UnKnown
Address: 192.168.1.1
Name: avatw.search.yahoo2.akadns.net
Address: 72.30.186.25
Aliases: www.altavista.com
The reason the server is unknown, is because there is no reverse mapping
for a private address (192.168.1.1). In other words, the computer asks
the router. The router in turn, consults one of the two DNS servers
it was passed, via DHCP, from the ISP. There is no symbolic equivalent
to 192.168.1.1, which is why it has to remain "UnKnown".
But I can see the actual servers used, in my router setup page.
The fact that I got a translation, means it worked, and one of
my two DNS servers at the ISP, was working.
For people who have a static setup for their Windows computer, the
server name could have been translated and named, because then the
nslookup program would be dealing with a public DNS server directly.
If you're not getting the "72.30.186.25" part of the answer, then
DNS is broken. You could talk to the staff at your ISP, for example,
to seek a resolution. I've used workarounds in the past, to avoid
phoning them Such as manually setting up DNS, when there is a
problem. Now that there are so many more DNS servers at my ISP, this
no longer seems to be an issue here.
Paul
Hi Paul,
Thanks for the replies but you're now talking over my head.
What does that mean the "DNS is broken"?
I also don't really know who my Internet Service Provider is?
I connect using a Sprint broadband card. Would Sprint be my ISP?
Sorry for the dumb questions!
Joe
Somewhere, in the documentation you got from Sprint, there should
have been a phone number to call, to get support for your Internet
service. That is who you want to call now. If the conclusion is,
that DNS (domain name service, translating symbolic addresses, to
numeric addresses) is broken, then you should talk to the support
people.
Another way to evaluate this. If you go to your web browser, and
type in
http://www.altavista.com
and that doesn't work ("server not found" or whatever).
And then you try instead,
http://72.30.186.25
the second format avoids the DNS translation you should have working
for you. Nobody wants to type in or remember numbers, which is why
we have symbolic addresses instead. The DNS server performs
the translation from the first form, to the second form. The
number form is needed, because numbers are stuffed into the
headers of each packet, indicating where the packet should
go.
DNS servers are an integral part of the service. The "fat pipe"
to Sprint can be working, but it there is no working DNS server,
it'll be damned hard to get anything done.
If your router has a WAN page in the setup for the router,
you might see the addresses of the DNS servers listed.
Keeping track of the DNS servers that are working or not
working, might help when you're talking to Sprint. In
case they offer the usual "we don't see a problem here sir"
kind of answer. I know I've had to do extra research work,
to get any kind of admission from the support at my ISP,
which is why I don't waste a lot of time on them.

Cool.
This must mean that your ISP was having trouble on their side, and your
hardware was doing all it could to keep you connected. |
