Help!!! Urgent!!!! Internet Not Working!!!!

[nileshgr]

We were talking about static IPs in the internal network. The IP of the external network is not causing your problem. Assign static IPs, subnet, gateway, DNS as suggested above and try.



I gave you the link for the modem, no issues with linux, also to illustrate the live cd option.

I am able to access the modem config page using static LAN. But i am unable to access the WWW.

I know that baba, never mind, if you don't want to try it don't

Do you have any option to check internet connection from router? Can you ssh/telnet into the router?
The Unknown, can you rather connect your dad's windows PC directly and see if it works?

Nah. There is no ssh or telnet to the router.

WHERE AM I POSTING INTO THIS FORUM MAN ????

I AM POSTING THIS FROM MY DAD's WIN32 LAPPY!!!!

 

[NucleusKore]

The Unknown, I got an IDEA!!!!!!
In your dad's Windows laptop (I assume its XP or 2000), Go to Start->Run->command
At prompt type

ipconfig /all

and post the output here. We might just know what's happening and why windows is able to browse automatically.

Just look at this

IP Address. . . . . . . . . . . . : 123.236.170.84
Subnet Mask . . . . . . . . . . . : 255.255.254.0
Default Gateway . . . . . . . . . : 123.236.170.1

No wonder we were all farting here.

Your default gateway is 123.236.170.1, and so your IP should be in that range, in this case it has taken 123.236.170.84
Manually in linux you could assign 123.236.170.[size=+1]2[/size] and onwards

Looks like a problem in the DHCP module of Fedora, I had a problem with the DHCP of SuSE 9.3 Professional, allbeit a different one.

 

[nileshgr]

Previously I never used to set them. All those were automatically obtained via Dynamic Host Configuration Protocol (DHCP)

 

[NucleusKore]

My suggestion:
First disable DHCP. You may enable it later after updating your distro.
As I have described above, configure you linux network for manual settings as follows
IP Address. . . . . . . . . . . . : 123.236.170.84
Subnet Mask . . . . . . . . . . . : 255.255.254.0
Default Gateway . . . . . . . . . : 123.236.170.1
DNS Servers . . . . . . . . . . . : 220.225.236.84
220.225.236.85
202.138.96.47

Try now and see. IT SHOULD BROWSE.

Then update your Fedora online. If one of the modules is DHCP, then you're on the way to recovery.

The IP would change when I remove the cable from my dad's lappy. So can't do it now. Also, my box is off now. I will write this in a piece of paper and try it tommorow. But the problem is the IP. Its dynamic and changes from pc to pc.

UPDATE- I THINK I FOUND THE PROBLEM. I ran dhclient today @ 4pm. It got the same DHCPDISCOVER message which @chaitanya posted. But the subnet mask was 255.255.255.255

and reliance's subnet is 255.255.254.0

 

[NucleusKore]

Yes, but please understand, as long as it is in the range allotted in the router, it is not illegal, and will browse.

*img217.imageshack.us/img217/9472/pubthefuture2cisopen466cr4.png

 

[nileshgr]

but why then DHCP doesn't get the IP address ?

 

[NucleusKore]

Sorry I am not a programmer. When I first installed SuSE 9.3 Professional, my system would not take the network settings on boot. It would attempt a DHCP and fail.
However on giving

service network restart

it would take the settings automatically!!

This problem was not resolved by updating online at the time. This forced me to learn a little networking I've been using static IP ever since. Static IPs are great especially when you use P2P, as you can set the routing and NAT, giving you a more stable experience.

So as you have updated above, the DHCP module is having a problem, maybe you can file a bug report But please get your internet working first.

*img217.imageshack.us/img217/9472/pubthefuture2cisopen466cr4.png

 

[nileshgr]

Even service network restart doesn't help me. BTW, doesn't your IP change or you are paying the rent ?

 

[NucleusKore]

My internet story-

Internet was working in F7. I formatted and installed F8.

Now I am unable to get the IP address.

On setting a local ip 192.168.1.2 ; i can login to the DSL router 192.168.1.1 though I don't require it to tune coz reliance dsl is a web-login system @ reliancebroadband.co.in

NOW I AM NEITHER ABLE TO ACCESS INTERNET ON F8 OR F7

AND MY LAN CARD IS WORKING. PLEASE HELP!!!!

Your first post too was misleading, I thought your gateway is 192.168.1.1
Funny you could access it!!!!!

Even service network restart doesn't help me. BTW, doesn't your IP change or you are paying the rent ?

The IPs we set are of the internal network. The IP you have to pay rent for is for your External router IP which is visible to the world. That changes each time you reboot your router.

Just as your system leases an IP from the router, your router leases an IP from reliance DHCP each time it is switched on.

[nileshgr]

^ WRONG! The steps may be correct but suppose first the router is connected to my pc and i get an ip 123.236.171.240 then when I remove the lan cable and put it in my dad's lappy, I get another IP like 123.236.170.96

 

[NucleusKore]

Yes, I assumed you'd understand that, follow those steps, but use the IPs I mentioned above

*img217.imageshack.us/img217/9472/pubthefuture2cisopen466cr4.png

 

[nileshgr]

I have them on a piece of paper. Will try 2moro. Hope it turns to be a success.

btw, i will not switch off my router so that possibly the ip remains the same.

 

[NucleusKore]

1) Disable IPv6. Use the system network config tool

*img341.imageshack.us/img341/2491/netconfigdhcpak3.th.png

Select your interface, click edit, and uncheck the Enable IPv6 configuration option. Enter static IP 123.236.170.84, subnet 255.255.254.0 and save.

2) Then click on manually, type gateway 123.236.170.1, DNS - 220.225.236.84
220.225.236.85
202.138.96.47

Go Next and save your settings

3) In a terminal as root: service network restart

4) ifconfig
and post the output here

For reference: Fedora 8 Network configuration

Happy?

hah! you gave me the link to fc4 config!!! I use f8. btw, its install time config guide. I have system-config-network-gui installed.
