Connected to router but can"t get to internet

[dedotch]

I have a problem with a setup that was working fine. I have a ADSL modem plugged into a Linksys router. 2 computers. 1 LAN one WLAN. They are connected to each other no problem. The Router interface comes up on both. The modem interface shows connection is up. The wireless computer connects to the internet no problem but the LAN will not get online. No internet, no mail, nothing. I have tried Explorer, Avant, and Firefox. No go. Is my winsock damaged maybe?

Please Help.

What IP does your wireless connection get, what IP does your wired connection get? Is it something with that? Something with the gateway address? Something with your DNS? Can you ping anything?

A little more info is needed methinks.

 

[dedotch]

This is what I have tried w/ limited knowledge.
The router gives an ip of 192.168.2.100 as the first address. I kept getting the error can't renew the ip address.
So I specfied one 192.168.2.101

Sub net 255.255.255.0

Defalt Gateway 192.168.2.1

The DNS 4.2.2.2
did not know an alternate.

Like I said I can access the router and modem fine.
Have not pinged anything. I am not at home now. I will try to ping some sites tonight.

 

[captaincrunch00]

The router will give you as many addresses as you specified it could.
If you told the router to start giving numbers at .100 and only give 1 address, that address is probably in the wireless card so your wired computer doesnt have an address to use.

The routers internal IP address is what?

The Wireless PCs address/gateway/dns is set to what?

The above info is for your wired PC? Set it back to DHCP and let it find an address from the router on its own, you shouldnt have to set it manually if you are giving out enough addresses.

 

[dedotch]

The laptops info
address 192.168.2.105
sub 255.255.255.0
gateway 192.168.2.1

The router is set to enable DHCP
the starting ip is 192.168.2.100
it is set to 50 addresses

the reason I gave it an address is when I set to automaticly aquire an sddress it can't obtain one.
I even went to cmd prompt and did ipconfig/release and then ipconfig/renew
It would not renew.
I don't think I ever turned off everything and brouht them back up one at a time. What order woutl you recomend.
Modem-Router-PC?

 

[captaincrunch00]

Yeah, that order.

I'd wait for all the lights to stop blinking before you turn on the next thing.

Your router should have an IP from the modem with a DNS and everything, I'd check that and use that if you have to set a static address.

Do you have another ethernet cable to try from the PC to the Router? Is the Network Interface Card enabled? Does it show up as working properly in Device Manager? Are you getting any link lights on the NIC and router?

 

[dedotch]

I believe the cable and card are good. I can connect to the router interface and to the other computers' drives. The only thing seeming to be not working is the a internet. I am going to do a cold boot on all systems tonight.

Thanks for the help.

 

[Freestone]

I went through all the suggestions since DHCP isn't working on your PC. If the reset doesn't work, report back the OS and Service Pack level so we know what we are dealing with. Any firewall software on the "broke" PC?

 

[cdogg]

The Router interface comes up on both

This piece of info is important. This eliminates a lot of the concerns touched on in other posts.

I noticed you tried to force a DNS setting. That's probably the problem here. You shouldn't have to. A good test to see if you have a DNS issue is to ping the IP address of a web page such as Yahoo:

1) Go to Start -> Run, type cmd and hit OK
2) Type ping 68.142.226.47 and hit enter
- If you get replies, then you know that there is likely an issue with your DNS, HOSTS file, or Winsock configuration.

I strongly recommend you try setting all DHCP (WINS & DNS) back to their defaults on both the router and PC. Make sure you are using Dynamic IP assignments from the router, and that the PC is set to "obtain IP address automatically".

Have you tried doing an IPCONFIG/ release and then a renew? You might also want to unplug the router and shutdown the pc for a couple of minutes. Then restart the router, then the pc's and see if that works.

 

[cdogg]

PRPhx,
If he can pull up the router setup screen from the PC, then we know that the network card, cable, router and IP assignment is not the issue. Turning everything off/on doesn't hurt to try, but if the ethernet connection is already working, it shouldn't make a difference.

Can you set the router back to default?

When in doubt start again!

I am not a fan at all of Linksys routers. I find them flakey at times and they will drop random computers off the internet at random times.
I solved 100% of my router issues by buying a high quality D-link router.
Now that I am done with venting on the perils of Linksys routers. on to your issues.

first assign an IP address that is NOT in the dynamic IP range the router assigns
192.168.2.2 thru 192.168.2.99 should be OK to assign manually.
just for sake of making it easy assign the Lan connection as:

address 192.168.2.10
sub 255.255.255.0
gateway 192.168.2.1
primary DNS 192.168.2.1
no secondary DNS assigned



The DNS should be assigned the by the router. thru the 192.168.2.1 address
this should fix the internet issue.

the wireless try:

address 192.168.2.20
sub 255.255.255.0
gateway 192.168.2.1
primary DNS 192.168.2.1
No secondary DNS assigned

this is how I run my router and I am running a mixed system of wireless, 1 gig LAN,lots of devices such as printers to network harddrive's, and multiple computers

Some I let the Router assign the IP and some I have to run as a static IP for proprietary software

The most important thing is to never assign an IP address in the same range as what the router assigns dynamically.
because the router will assign the same IP address that you assigned manually so you end up with 2 computers with the same IP address and a locked up and very confused network.


Good luck

I am truly amazed that so many people are willing to give up their time to help others. Thanks. I did two things last night. Reset all to auto and rebooted everything. modem-router-PC. I also uninstalled a third party firewall. I think with windows and the router I will have enough pertection. One of the two worked. More than likely the reboot. I have had some trouble with the firewall and this network before.

Thanks for all your help.

cdogg:
True, it shouldn't make a difference, but sometime weird things happen and powering everything off and then back on does fix things.

I mention this from personal experience. I have a wired Linksys router and every so often everything seems to be working, but web pages refuse to load. IF I unplug my router, wait a minute or two, plug the power to it back in and let the router re-init, everything works fine. Howevewr, at other times that doesn't work and I need to turn off the pc, router and modem. Very annoying at times.

 

[cdogg]

PRPhx,
I, too, have a Linksys router on my home network (one of the old revisions of the badboy BEFSR41 that I bought back in 2001). The issue you describe can sometimes be solved by powering the router off/on, but did you ever wonder why?

When it happens to me, stopping & restarting the broadband connection in the router config (on the status tab) fixes it almost every time. When people say they had to turn their router off and on to fix a problem, this is really what they're doing that makes a difference. Occasionally when it doesn't fix it, the broadband modem then has to be power-cycled. At work, where I support many other models from D-Link, Netgear, and Linksys, the same is true. Rarely does the router have to be powered off.

Too often do I see advice or suggestions that the router is to blame. In dedotch's situation here, the PC using wireless through the "same" Linksys router was able to connect to the internet just fine. Therefore we immediately know that the router and the broadband modem are fine. Though it doesn't matter now, I suspect the firewall or some process running in Windows was to blame...

cdogg,
I have to agree with you.

I do think that the computers were not seeing the DNS setting the router was sending
"Defalt Gateway 192.168.2.1

The DNS 4.2.2.2"

the DNS should been set as 192.168.2.1

what clued me was the fact the 2 computers could see each other on a LAN/wireless


so in effect he was blind to the internet because of the DNS setting


I had to learn that the hard way.....LOL

 

[dedotch]

Gentlemen I have a setup at work in which I have the same routh and a switch that I have 6 computers all LAN I have disabled the WLAN on the router. When I disabled the wireless I could not get online with any of the computers. Linksys gave me these settings for DNS and they do work.
In fact I was having IP address conflicts so I asigned all the computers forced IP address 192.168.2.101 - 192.168.2.107 and they have been good to go ever since.
That is why I tried those settings at home.

4.2.2.2
38.9.212.2

 

[firewolfrl]

dedotch,
Your IP conflicts were because the router assigns addresses BLINDLY in the range you allocated for it to assign...it assigns the addresses that are allocated in that range and does not see any computer that is assigned the same IP address manually.

example:
192.168.2.1 is the Router
you can manually assign any computer in this range because the router does not assign any computer or device in this range. (this is your forced IP)
192.168.2.2 to 192.168.2.99

the router assigns and allocates in numerical order (BLINDLY)...it only sees what it assigns
192.168.2.100 to 192.168.2.255

so your router can assign up to 155 computers in your network in that range dynamically

and you can assign manually (forced or static) 98 computers


As for the DNS addresses ...are you using the same ISP as your work?
some ISP's just don't work with another company's DNS server

here is are some good ways to find the DNS servers for your ISP

1. Call your ISP and ask for it (easiest)
2. Look at the DNS addresses on the router for the internet
3. Run CMD then IPCONFIG /all |more

when you reset and let all the computers see the router it assigned the correct DNS setting for the internet

Hey I am just glad you got your system working so all is good and serene in the universe...LOL
