DSL Internet Connection Woes

I'm trying to track down where my interenet connection dies.  Around every ten minutes it seems to lose connection and vpn connections are impossible.  Also at time "Detecting proxy server" sits there for 10 minutes when I open up the browser for the first time . Are there any utilities out there that can help?  I connect through a Linksys router model BEFW11S4 connected directly to my PC with a patch cable.

When I ping for example msn.com, I get request timed out; although I can surf with no problem.  Here's what my ipconfig looks like if that helps.

Do you use any proxy settings or it is just the regular
cable modem ------> Router ----> PC
and you get IP address using DHCP ?

If no proxy then ,

a) Check if the connection between cable modem to your NIC card (in the PC) , works fine ?

b) Change the ethernet cable between router and the PC to see if there is any difference ?

c) If you messed around with the configurations of the router which you think might started this issue , then reset the router after backing up all the configurations that you must have done..

Nice catch Steve.. Long time no see..

Jhaiken,

If you are going to use DHCP , you generally donot assign any IP address so there would be NO DNS servers.
If you are using Static IP on your machine ,
give the following for DNS servers and see what happens

Primary DNS server : 192.168.0.1
Secondary DNS server : 4.2.2.2

NO PROXY

YES

One other thing: If I try to open a second browser it sits at "Detecting proxy settings" forever.
jhaiken,

Guess you are using Internet Explorer.
Open IE
go to tools ---> internet options ---> connections ---> LAN settings
and uncheck all the options (if checked and if you donot need)
Now press OK
Close the browser.

Open it again and check if you can connect to internet..

Apart from internet browser, can you sign in to Yahoo or MSN messenger
and can you download emails in your Email client ?

Yes, those seem to be fine
Have you tried my other suggestions in my first comment..

Also do these to see if it would help

Can you connect directly to the cable modem to see if it would work ?

Now if you can directly connect to cable modem and internet works fine , then do these

Power off cable modem
Press the reset button at the back of the router for 2 mins. Power off router
Now turn on the cable modem
wait for 2 mins before all the lights come
once the lights come , turn on router . Wait until the WAN light comes.
Then connect the cable from router to your computer.
If it doesnot get the IP address , restart your computer. Check if you get the IP address and then check if you can connect to internet.

Make sure going to LAN connection's network properties to see there is no static IP address setup.


You receive an "An operation was attempted on something that is not a socket" error message when you try to connect to a network

MSN Does not accept ping request so are many servers in the internet.

That is a DNS issue.

What does your network look like?

1.-  Cable/DSL modem---->router----->server---->Workstation
2.-  Cable/DSL modem---->router-----> Server and/or workstation

I am having a problem with 10.0.0.1 as your DNS server.

What is your router IP Address?
Do you have antother DHCP server beside your router acting as a DHCP server?
Do you have a Server and do you have active directory installed?

Let me know.

Cheers!

NO

NO

Funny that I am not getting the DNS address from my ISP.  Perhaps I need something from them for my router setup???

For your DNS to show as that, it is being provided by something.  Look at what DHCP is pushing for DNS, whether it is from a server or your firewall or router.  Make sure the machines do not have DNS statically set on them.  Usually the router gets a dynamic IP from the cable modem and pushes the DNS it gets from the ISP out to the workstations.  OR, if the Cable modem has a static setup, sometimes you have to manually set it on the workstations....  Anyway, either the workstation (s) have a static DNS set on the network adapter or it is being pushed out by your DHCP server.

Vico1,

     IMHO, The Wan Ip is really irrellivant in this case as it simply seems like an incorrect DNS setting.  He is on the Private 192.168 range and for some reason the DNS is showing up as another private 10.x.x.x range.  Fix this and the problem will most probably disappear.
checxk the dns tab of the tcp properties, it appears someone has entered a dns server ip address of 10.0.0.1

Update on this:

I found out that the modem that was supplied to me by the ISP is doing DHCP and will only connect to the ISP if that is enabled.  I turned it off and couldn't get anywhere.  That would explain the DNS entry of 10.0.0.1

Not sure how I get around this; so I can have my wireless router do the DHCP.
